PROSPECTUS SUPPLEMENT

(To Prospectus dated May 4, 2026)

BRT APARTMENTS CORP.

Dividend Reinvestment Plan

$16,000,000 of shares of Common Stock

This prospectus supplement relates to $16,000,000 of shares of common stock, par value $0.01 per share (the "Common Stock"), of BRT Apartments Corp. (the "Company," "we," "us" or "our") that may be offered and sold from time to time pursuant to the BRT Apartments Corp. Dividend Reinvestment Plan (the "Plan"). This prospectus supplements, and should be read together with, the accompanying prospectus dated May 4, 2026 (the "Base Prospectus"). This prospectus supplement describes the terms of the Plan. To the extent that information in this prospectus supplement differs from or updates information contained in the Base Prospectus, you should rely on the information in this prospectus supplement.

The Plan provides an economical and convenient way for our stockholders to invest in our Common Stock. Through participation in the Plan, you will have the opportunity to reinvest cash dividends paid on your shares of Common Stock in additional shares of Common Stock, at a discount ranging from 0% to 5%, as we may determine from time to time in our sole discretion. As of the date of this prospectus supplement, we are offering a discount of 3% on the price of shares of Common Stock purchased directly from us through the reinvestment of dividends pursuant to the Plan. We reserve the right to change or eliminate the discount at any time. (See Question 12 for more detailed information regarding the calculation of the price at which dividends are reinvested.)

Our shares of Common Stock are traded on the New York Stock Exchange under the symbol "BRT." On September 24, 2026, the closing price of our Common Stock as reported on the New York Stock Exchange was $13.70 per share.

Investing in our Common Stock involves risks. See "Risk Factors" beginning on page S-5 of this prospectus supplement, page 6 of the Base Prospectus and in the documents incorporated by reference herein for a description of certain factors you should consider before investing in our Common Stock.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR DETERMINED IF THIS PROSPECTUS SUPPLEMENT IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the terms of the Plan and adds to and updates information contained in the Base Prospectus and the documents incorporated by reference into this prospectus supplement and the Base Prospectus. The second part is the Base Prospectus, which provides more general information about us and the securities we may offer under our Shelf Registration Statement, some of which does not apply to the Plan. If the description of the Plan varies between this prospectus supplement and the Base Prospectus, you should rely on the information in this prospectus supplement.

Please read this prospectus supplement and the Base Prospectus carefully. If you own our Common Stock now, or if you decide to buy it in the future, please keep this prospectus supplement with your permanent investment records, since it contains important information about the Plan.

You should rely only on the information contained in or incorporated by reference into this prospectus supplement and the Base Prospectus. We have not authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. This prospectus supplement may only be used where it is legal to sell these securities. You should not assume that the information contained in this prospectus supplement is accurate as of any date later than the date hereof or such other dates as are stated herein or as of the respective dates of any documents or other information incorporated herein by reference.

Table of Contents

In this prospectus supplement, the words "we," "us" and "our" refer to BRT Apartments Corp. and its subsidiaries.

SUMMARY OF THE PLAN

The following summary of the Plan omits certain information that may be important to you. You should carefully read the entire text of the Plan contained in this prospectus supplement before you decide to participate in the Plan.

Enrollment

You can participate in the Plan by completing and submitting the attached Enrollment Form to the address set forth on (i) such form or (ii) under the caption “Summary of the Plan - Administration.” You may also obtain an Enrollment Form from the Plan Administrator, Equiniti Trust Company, LLC, by accessing its website at www.equiniti.com/us/. Please see Questions 5 and 8 for more detailed information.

If you were enrolled in our dividend reinvestment plan immediately prior to the date of this prospectus supplement (the “Prior Plan”), you will be enrolled automatically into this Plan, and do not need to submit a new enrollment form.

Reinvestment of Dividends

If you are a stockholder of record, you can reinvest any cash dividends paid on all or a portion of your shares of Common Stock. You will be able to purchase shares of Common Stock by reinvesting your dividends without paying any brokerage commissions or other fees on stock purchased directly from us. Except for the restrictions contained in our articles of incorporation (the "Charter") with respect to the ownership and transfer of our shares, the reinvestment of any cash dividends paid on your Common Stock is not subject to a maximum limit. The Plan does not include an optional cash purchase feature; only reinvested dividends may be used to purchase shares of Common Stock under the Plan. Please see "Sources of Shares of Common Stock" and Questions 7 and 9 for more detailed information.

Administration

Equiniti Trust Company, LLC, the transfer agent for our Common Stock, will serve as the plan administrator of the Plan (the “Plan Administrator” or “Equiniti”). All correspondence to the Plan Administrator should be sent to: Equiniti Trust Company, LLC, 1110 Centre Point Curve, Suite 101, Mendota Heights, Minnesota, 55120, Attention: Shareholder Relations. If you are inquiring about enrollments, termination, sale of shares or if you desire to view your account balance, you may log onto the Plan Administrator's website at www.equiniti.com/us. Please see Question 5 for more detailed information.

Source of Shares of Common Stock

Generally, Common Stock purchased by the Plan Administrator under the Plan will come from our authorized but unissued shares of Common Stock. However, we may, in our sole discretion, direct the Plan Administrator to purchase shares of Common Stock in the open market or in privately negotiated transactions with third parties. If shares of Common Stock are purchased for you in the open market or in privately negotiated transactions, you will not receive any discount. Please see Question 11 for more detailed information.

Table of Contents

Purchase Price

Purchases from Us

The purchase price for shares of Common Stock that the Plan Administrator purchases directly from us for dividend reinvestments under the Plan will be equal to the higher of:

•

97% (or such other discount as may then be in effect) of the average of the high and low sales prices of a share of our Common Stock during the five days on which the NYSE is open and for which trades in shares of Common Stock are reported immediately preceding the relevant purchase date, or, if no trading occurs in the shares of Common Stock on one or more of such days, for the five days immediately preceding the purchase date for which trades are reported; and

•

97% (or such other discount as may then be in effect) of the average of the high and low sales prices of a share of our Common Stock on the purchase date.

The share prices to be used in the calculation will be the prices reported on the NYSE Composite Transactions Tape and all price calculations will be computed to four decimal places. The discount is subject to change from time to time, in our sole discretion, but will be between 0% to 5%. We will advise participants through a press release of any change in the applicable discount at least five days prior to the effective date of the change. Please see Question 12 for more detailed information.

Purchases on the Open Market

The purchase price for shares of Common Stock purchased in the open market or in privately negotiated transactions with third parties will equal the weighted average of the purchase prices paid for the shares, as computed to four decimal places by the Plan Administrator. Please see Question 12 for more detailed information.

Tracking Your Investment

You will receive periodic statements of the transactions made in your Plan account. These statements will provide you with details of the transactions and will indicate the share balance in your Plan account. Please see Question 20 for information on your transaction statements.

THE COMPANY

We are a real estate investment trust, also known as a REIT, that is focused on the ownership, operation and, to a lesser extent, development of multi-family properties. These properties may be wholly owned or owned by unconsolidated joint ventures in which we generally contribute a significant portion of the equity. Please see our reports and filings with the Securities and Exchange Commission (the “SEC”), incorporated by reference into this prospectus supplement, for a description of our current property portfolio and operations.

Our corporate office is located at 60 Cutter Mill Road, Suite 303, Great Neck, N.Y. 11021 and we can be contacted at 516-466-3100. We maintain a website at www.brtapartments.com. The information contained on or connected to our website is not incorporated by reference into this prospectus supplement, and you must not consider the information on our website to be a part of this prospectus supplement.

We intend such forward-looking statements to be covered by the safe harbor provision for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and include this statement for purposes of complying with these safe harbor provisions.

We have no duty to, and do not intend to, update or revise the forward-looking statements we make in this prospectus supplement (including any information incorporated by reference into this prospectus supplement) whether as a result of new information, future events or otherwise, except as required by law.

Any such statement so modified or superseded shall only be deemed to constitute a part of this prospectus supplement as it is so modified or superseded.

RISK FACTORS

Investing in our securities involves significant risks. Please see the risk factors immediately below and under the heading “Risk Factors” in our Base Prospectus and in our periodic reports filed with the SEC under the Exchange Act, which are incorporated by reference in this prospectus supplement. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus supplement, the Base Prospectus and any other applicable prospectus supplement. The risks and uncertainties we have described are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations.

In addition to the risk factors incorporated by reference into this prospectus supplement, below is a description of certain risks that you may face by virtue of your participation in the Plan. There may be additional risks that are not listed below or in the referenced documents, and you should consult your financial, tax, legal and other advisors prior to determining whether to participate in the Plan.

There is no price protection for your shares of Common Stock in the Plan. Your investment in the shares of Common Stock held in the Plan will be exposed to changes in market conditions and changes in the market value of shares of Common Stock. Your ability to liquidate or otherwise dispose of shares of Common Stock in the Plan is subject to the terms of the Plan and the withdrawal procedures under the Plan. You may not be able to withdraw or sell your shares of Common Stock in the Plan in time to react to market conditions.

The purchase price for shares of Common Stock purchased or sold under the Plan will vary. The purchase price for any shares of Common Stock that you purchase or sell under the Plan will vary and cannot be predicted. You may purchase or sell shares of Common Stock at a purchase price that is different from (more or less than) the price that you would face if you acquired or sold shares on the open market on the related dividend payment date, purchase date or sale date, as appropriate.

Because our Common Stock is not actively traded and the market price for our Common Stock varies, you should purchase shares of Common Stock for long-term investment only. Although our Common Stock is listed on the NYSE, our Common Stock is not actively traded. We cannot assure you that there will, at any time in the future, be an active trading market for our Common Stock. Even if there is an active trading market for our Common Stock, we cannot assure you that you will be able to sell all of your shares of Common Stock at one time or at a favorable price, if at all. As a result, you should participate in the Plan only if you are capable of, and seeking, to make a long-term investment in shares of Common Stock.

We may reduce or eliminate the discount for shares purchased pursuant to the Plan. A benefit of participating in the Plan is that you may be able to reinvest your dividends and acquire our shares at a discount to the then trading price. (See Questions 3, 4 and 12 for further information.) While the discount is currently 3% (although we can increase it up to 5%), we reserve the right, without notice to you (to the extent permitted by law, we will announce the change in the discount by issuing a press release and not by a notice sent to participants in the Plan) to reduce or eliminate the discount. Further, if we elect to have the Plan Administrator purchase the shares in the open market or privately negotiated transactions (see Question 12 for further information), which election may be made without notice to you, there will be no discount with respect to such purchase, and you will be responsible for your pro rata share of fees and commissions, including brokerage fees, incurred in connection therewith. We reserve the right to reduce or eliminate the discount at any time for any reason whatsoever and the reduction or elimination of the discount, which you may not be aware of, may make participation in the Plan of less benefit to you.

S-5

Table of Contents

You will not earn any interest on your dividends pending investment. No interest will be paid on dividends or other funds pending investment or disbursement.

You may incur tax obligations without receiving cash with which to pay those obligations. If you acquire shares by reinvesting dividends under the Plan, you will be treated for U.S. federal income tax purposes as if you received a cash distribution on the date the shares are acquired in an amount equal to the fair market value of the shares acquired under the Plan (including the shares you acquired as a result of the Plan discount) on that date. Any income tax obligation you incur will be the same as if you received such distribution in cash but you will have to pay that obligation using funds from other sources. Certain participants may also be subject to an additional non-deductible 3.8% tax on “net investment income.” See Question 23 for a description of certain U.S. federal income tax consequences of participating in the Plan.

Plan accounts are not insured or guaranteed by the FDIC or any other governmental agency. Shares of Common Stock held in your Plan account, and any cash dividends or other funds held by the Plan Administrator pending investment or disbursement under the Plan, are not deposits, savings accounts, or other obligations of any bank or depository institution, and are not insured or guaranteed by the Federal Deposit Insurance Corporation, the Securities Investor Protection Corporation, or any other federal or state governmental agency or instrumentality. An investment in shares of Common Stock through the Plan is subject to the same investment risks as a direct investment in our Common Stock, including possible loss of principal, and neither we nor the Plan Administrator makes any representation regarding, or assumes any responsibility for, the safety of your investment beyond what would apply to a direct holder of our Common Stock.

Certain lawsuits and other legal proceedings against us or certain of our representatives may be brought only in certain courts and jurisdictions, which limits your ability to seek redress against such persons. Our bylaws (the “Bylaws”) provide that, unless we consent in writing to the selection of an alternative forum, the Circuit Court for Baltimore City, Maryland, or the Supreme Court of Nassau County, New York, or, if neither such court has jurisdiction, the U.S. District Court for the District of Maryland, Baltimore Division, or the United States District Court for the Eastern District of New York, will be the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of any duty owed by any of our directors, officers or other employees to us or to our stockholders, (3) any action asserting a claim against us or any of our directors, officers or other employees arising pursuant to any provision of the MGCL, the Charter or the Bylaws, or (4) any other action asserting a claim against us or any of our directors, officers or other employees that is governed by the internal affairs doctrine.

This provision may limit your ability to choose the jurisdiction in which you desire to bring a claim against us or our representatives. Alternatively, if a court were to find the choice of forum provisions contained in our Bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could materially adversely affect our business, financial condition and operating results. For example, under the Securities Act, federal courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act, and investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. In addition, the choice of forum provisions described above do not apply to any actions brought under the Exchange Act.

TERMS AND CONDITIONS OF THE PLAN

The following constitutes our Dividend Reinvestment Plan. All references in this prospectus supplement to "Common Stock" refer to our shares of common stock, par value $0.01 per share.

S-6

Table of Contents

Purpose

1. What is the purpose of the Plan?

The purpose of the Plan is to provide our stockholders with a simple, convenient and cost effective way to reinvest all or a portion of their cash dividends in additional shares of our Common Stock. To the extent that shares of Common Stock are purchased directly from us, we will receive additional funds to repay debt, make investments in real estate and for other purposes. See Question 12 and “Use of Proceeds.”

Participation Options

2. What are my investment options under the Plan?

Once enrolled in the Plan, you may increase your holdings of Common Stock through the following investment options:

•

Full Dividend Reinvestment. You may have cash dividends paid on all of your shares of Common Stock automatically reinvested in additional shares of Common Stock.

•

Partial Dividend Reinvestment. You may have cash dividends paid on a specified number of your shares of Common Stock held by you automatically reinvested in additional shares of Common Stock. We will continue to pay you cash dividends on your remaining shares of Common Stock.

The Plan does not include an optional cash purchase feature. Only reinvested dividends may be used to purchase shares of Common Stock under the Plan.

Advantages

3. What are the advantages of the Plan?

The advantages of the Plan are as follows:

•

Reinvestment of Dividends. Participants may purchase additional shares of Common Stock automatically by reinvesting all or a portion of their cash dividends. Dividend payments not reinvested will be paid by check. (Except as otherwise expressly indicated or the context otherwise requires, references in this prospectus supplement to payments “by check” include direct deposit or other similar forms of electronic payments or credits to an account that you have designated with the Plan Administrator, if and to the extent you have registered with the Plan Administrator for such electronic payments).

•

Fractional Shares. All cash dividends paid on a participant's shares of Common Stock are fully invested in additional shares of Common Stock because the Plan permits fractional share interests to be credited to Plan accounts. In addition, dividends will be paid on, and may be reinvested with respect to, such fractional share interests.

•

Discount. We may offer a discount of up to 5% of the market price on purchases of shares of Common Stock under the Plan for stock purchased directly from us. Currently, we offer a discount of 3.0% for reinvested dividends. We will advise participants through a press release of any change in the applicable discount at least five days prior to the effective date of the change. If you hold your shares in the name of a broker, bank or other nominee, this discount will be available to you only if your broker, bank or other nominee elects to participate in the Plan on your behalf. See Question 6 and Question 8.

•

Sale or Transfer of Shares. Participants may request that the Plan Administrator effect the sale of a portion or all of their Plan shares. Please see Question 22 for additional information.

•

Reduced Fees. No brokerage commissions or fees are charged with respect to shares of Common Stock acquired directly from us with reinvested dividends. With respect to shares of Common Stock purchased with reinvested dividends on the open market or in privately negotiated transactions, you will pay your pro rata share of the brokerage commissions incurred by the Plan Administrator with respect to such purchase. With respect to shares of Common Stock you sell through the Plan Administrator, you will pay the Plan Administrator's applicable transaction and per-share fees then in effect. Please see Question 22 for more information.

•

Simplified Recordkeeping. Participants are furnished periodic statements which show the detail of each transaction and indicate the share balance of the Plan account, providing a simplified method of recordkeeping.

S-7

Table of Contents

Disadvantages

4. What are the disadvantages of the Plan?

The disadvantages of the Plan are as follows:

•

No interest paid on funds pending investment. No interest is paid on dividends held by the Plan Administrator pending reinvestment.

•

Purchase/sale price determination. Participants have no control over the share price or the timing of the purchase or sale of Plan shares. Participants cannot designate a specific price or a specific date at which to purchase or sell shares of Common Stock or the selection of a broker/dealer through or from whom purchases or sales are made. In addition, participants will not know the exact number of shares purchased until after the investment date.

•

Reinvested dividends will be treated as distributions for tax purposes. Participants who reinvest dividends paid on shares of Common Stock will be treated for U.S. federal income tax purposes as if they received a cash distribution equal to the fair market value of the shares acquired through the Plan (including the shares acquired as a result of the Plan discount) but will not receive cash to pay any tax payment that may be owed on such distribution. Regardless of any Plan discount, the amount of such distribution will equal the fair market value of the shares as of the date the shares are acquired under the Plan. Please see Question 23 for more detailed information.

•

No discount for open market or privately negotiated transactions. If we direct the Plan Administrator to purchase shares of Common Stock in the open market or in privately negotiated transactions with third parties (as we may do in our sole discretion without notice to you), you will not receive any discount on the purchase. As of the date of this prospectus supplement, we do not contemplate the purchase of shares of Common Stock in the open market or in privately negotiated transactions for dividend reinvestments.

•

The purchase price used in calculating the number of shares to be issued to you may not be as favorable as the purchase price you may have obtained had you purchased the shares on the open market. The number of shares of Common Stock purchased directly from us under the Plan is based on the share price that is determined by a formula described under Question 12. As a result of this formula, the purchase price under the Plan may not be as favorable to you, even after giving effect to the discount, as you would have obtained had you purchased the shares without participating in the Plan. Additionally, without giving you prior notice, we may direct the Plan Administrator to buy shares of Common Stock under the Plan either in the open market or in privately negotiated transactions with third parties. The purchase price for shares of Common Stock purchased in the open market or in privately negotiated transactions with third parties will equal the weighted average of the purchase prices paid by the Plan Administrator for the shares, you will not receive the benefit of any discount, and you will pay your pro rata share of the brokerage and similar fees incurred by the Plan Administrator in effecting such purchases. Please see Question 22 for more detailed information.

•

Delay of sales. Sales of shares held in the Plan may not take place promptly upon your request because the Plan Administrator will generally not sell shares more than once per day. Accordingly, sales of shares of Common Stock held in your Plan account may be delayed. (See Question 16 for more detailed information.)

•

Plan shares may not be pledged. You may not pledge shares of Common Stock deposited in your Plan account unless you withdraw those shares from the Plan.

Administration

5. Who will administer the Plan?

Equiniti Trust Company, LLC has been appointed as administrator of the Plan. Enrollment, sale of share requests and other transactions or services offered under the Plan should be directed to the Plan Administrator through use of any of the following:

Telephone. Customer Service Representatives are available 8:00 a.m. to 8:00 p.m., New York City time, Monday through Friday (except holidays) at 1-888-888-0144.

S-8

Table of Contents

In Writing. You may also write to the Plan Administrator at: Equiniti Trust Company, LLC, 1110 Centre Point Curve, Suite 101, Mendota Heights, MN 55120, Attention: Shareholder Relations. Be sure to include your name, address, daytime phone number, social security or tax I.D. number and a reference to BRT Apartments Corp. on all correspondence.

Internet. For terminations, sale of shares or to view account balances or history, you may visit the Plan Administrator's website at www.equiniti.com/us. In order to use the website, you must be enrolled in the Plan and have available your social security number and account number. Once you have gained access, you should follow the instructions on the menu.

Employees of the Plan Administrator are not permitted to give any opinions on the merits of any security or class of securities. The Plan Administrator may use, and commissions may be paid to, a broker-dealer that is affiliated with the Plan Administrator. Investors must make independent investment decisions based upon their own judgment and research.

We may replace the Plan Administrator at any time upon written notice to the Plan Administrator, and the Plan Administrator may resign as the Plan Administrator. If we replace the Plan Administrator or the Plan Administrator resigns, we may designate another qualified administrator as successor to the Plan Administrator for all or a part of the Plan Administrator's functions under the Plan. All participants will be notified of any such change. If we change the Plan Administrator, references in this prospectus supplement to the Plan Administrator shall be deemed to be references to the successor Plan Administrator, unless the context requires otherwise.

Participation

6. Who is eligible to participate in the Plan?

Record Owners. You are a record owner if you own shares of Common Stock that are registered in your name with our transfer agent. If you are a record owner, you may participate directly in any or all of the features of the Plan.

Beneficial Owners. You are a beneficial owner if you own shares of Common Stock that are registered in the name of a broker, bank or other nominee. If you are a beneficial owner, you must (a) become a record owner by having one or more shares transferred into your own name, or (b) coordinate your participation in the Plan through the broker, bank or other nominee in whose name your shares of Common Stock are held. If you wish to participate as a beneficial owner, your broker, bank or other nominee must itself enroll as a record owner and elect to participate in the Plan on your behalf; we and the Plan Administrator have no obligation to make the Plan, or any discount offered under the Plan, available to beneficial owners whose broker, bank or other nominee does not so participate. Whether, and on what terms, your broker, bank or other nominee makes the Plan available to you, including whether it will pass through any discount described in this prospectus supplement, is determined solely by your broker, bank or other nominee and not by us or the Plan Administrator. You should contact your broker, bank or other nominee directly to determine whether, and how, you can participate.

Plan Restrictions

7. What are the restrictions on participation in the Plan other than those described under Question 6?

Legality. You may not participate in the Plan if it would be unlawful for you to do so in the jurisdiction where you are a citizen, reside or to which you are otherwise subject. We reserve the right to terminate the participation of any participant if we deem it advisable under any applicable laws or regulations.

REIT Status. Our Common Stock is subject to certain restrictions on ownership and transfer designed, among other things, to preserve our qualification as a real estate investment trust, or REIT, for U.S. federal income tax purposes. In furtherance thereof, our Charter, among other things, restricts any person, with certain exceptions, from actually or constructively owning more than 6.0%, in value or number of shares, whichever is more restrictive, of our outstanding shares of Common Stock. Our Charter provides that we have various rights to enforce this limitation, including the transfer of such shares of capital stock to a trust. This summary of the ownership limitation is qualified in its entirety by reference to our Charter. We reserve the right to invalidate any purchases made under the Plan that we determine, in our sole discretion, may violate the ownership limitation set forth in our Charter or any REIT provision in the Internal Revenue Code of 1986, as amended.

S-9

Table of Contents

Our Discretion. We reserve the right to modify, suspend or terminate the Plan. Additionally, we may modify, suspend or terminate the participation in the Plan by any participant in order to eliminate practices which are, in our sole discretion, not consistent with the purpose or operation of the Plan or which adversely affect the price of our shares of Common Stock.

Enrollment

8. How do I enroll in the Plan?

If you are eligible to participate in the Plan, you may join the Plan at any time. Once you enroll in the Plan, you will remain enrolled until you withdraw from the Plan or we terminate the Plan or your participation in the Plan.

Enrollment Form. To enroll and participate in the Plan, you must complete the attached Enrollment Form and mail it to the Plan Administrator at the address set forth in such form or as indicated in the response to Question 5. You may also enroll by accessing the Plan Administrator's website at www.equiniti.com/us. If your shares of Common Stock are registered in more than one name (such as joint tenants or trustees), all such registered holders must sign the Enrollment Form. The Plan Administrator must receive a properly executed Enrollment Form by the dividend record date for the relevant dividend payment.

Record Holders. If you own shares of Common Stock that are registered in your name (not the name of a broker, bank or other nominee), you can enroll in the Plan by completing an Enrollment Form and submitting it to the Plan Administrator. As a record holder, you may participate in any of the services of the Plan.

Beneficial Holders. If you are a beneficial holder (i.e., your shares are not registered in your name but are held through a bank, broker or other nominee) you may arrange to have your broker, bank or such nominee participate in the Plan on your behalf. Whether your broker or bank agrees to participate in the Plan on your behalf, and whether it passes through to you any discount or other terms offered under the Plan, is a decision made solely by your broker or bank, in its discretion; neither we nor the Plan Administrator can require any broker or bank to participate in the Plan or to extend the discount to its customers. If your broker or bank does not participate in the Plan, you will not be able to reinvest dividends under the Plan unless you become a record holder. The Plan Administrator will not have a record of your transactions or your account since they will remain under the name of your broker or bank.

Dividend Reinvestment Options

9. How do I reinvest dividends?

Choosing Your Investment Options. If you elect to reinvest your dividends, you must choose one of the following when completing the Dividend Reinvestment section of the Enrollment Form:

•

Full Dividend Reinvestment: This option directs the Plan Administrator to reinvest the cash dividends paid on all of the shares of Common Stock owned by you then or in the future in additional shares.

•

Partial Dividend Reinvestment: This option allows you to specify a fixed number of full shares held by you on which you would like to receive a cash dividend payment and directs the Plan Administrator to reinvest the cash dividends paid on all remaining shares of Common Stock owned by you then or in the future. We will continue to pay you cash dividends, when, as and if declared by our board of directors, on the specified number of shares, unless you designate those shares for reinvestment pursuant to the Plan.

You should choose your investment option by checking the appropriate option(s) on the Enrollment Form, a copy of which is enclosed. If you sign and return an Enrollment Form without checking an option, the Plan Administrator will choose the "Full Dividend Reinvestment" option and will reinvest all cash dividends on all shares of Common Stock registered in your name. If you select both Full and Partial Dividend Reinvestment, the Plan Administrator will choose "Full Dividend Reinvestment."

S-10

Table of Contents

The Plan Administrator must receive a properly executed Enrollment Form by the dividend record date for the relevant dividend payment.

Changing Your Investment Option. You may change your investment option by contacting the Plan Administrator. The Plan Administrator must receive any change with regard to your participation in the Plan by the record date for a dividend payment in order for the change to be effective for that dividend payment. You may, of course, choose not to reinvest any of your dividends, in which case the Plan Administrator will remit any dividends to you.

Timing of Dividend Reinvestments

10. When are dividends reinvested?

The Plan Administrator will invest dividends in additional shares of Common Stock that are purchased directly from us on the dividend payment date, unless the dividend payment date is not a day on which the NYSE is open for trading, in which case the dividends will be invested on the next trading day. In the case of purchases on the open market or in privately negotiated transactions with third parties, the Plan Administrator will make such purchases as soon as practicable on or after the dividend payment date.

We cannot assure you that we will pay dividends on any particular schedule, and nothing contained in the Plan obligates us to do so. Neither we nor the Plan Administrator will be liable when conditions, including compliance with the provisions of our Charter and rules and regulations of the SEC or the NYSE, prevent the Plan Administrator from buying shares of Common Stock or interfere with the timing of such purchases.

For purposes of the Plan, we may aggregate all dividend reinvestments for participants with more than one account using the same social security or taxpayer identification number. For participants unable to supply a social security or taxpayer identification number, we may limit their participation to only one Plan account. In addition, all Plan accounts that we believe to be under common control or management or to have common ultimate beneficial ownership may be aggregated. Unless we have determined that reinvestment of dividends for each such account would be consistent with the purposes of the Plan, we have the right to aggregate all such accounts and to return, without interest, within 30 days any amounts in excess of the investment limitations applicable to a single account received in respect of all such accounts.

We pay dividends as and when authorized and declared by our board of directors. We cannot assure you that we will declare or pay a dividend in the future, and nothing contained in the Plan obligates us to do so. The Plan does not represent a guarantee of future dividends.

Common Stock Purchases

11. What is the source of shares to be purchased under the Plan?

All dividends reinvested through the Plan will be used to purchase either newly issued shares directly from us, or shares on the open market or in privately negotiated transactions with third parties, at our discretion. Shares purchased directly from us will consist of authorized but unissued shares of Common Stock.

Price of Shares Purchased

12. At what price will shares be purchased?

The purchase price for shares under the Plan depends on whether the Plan Administrator obtains shares in the open market or in privately negotiated transactions with third parties or by purchasing them directly from us. Specifically:

•

the purchase price for shares of Common Stock purchased in the open market or in privately negotiated transactions will equal the weighted average price of all the shares purchased by the Plan Administrator for all participating participants on the applicable purchase date; and

S-11

Table of Contents

•

the purchase price for shares of Common Stock that the Plan Administrator purchases directly from us will be equal to the higher

of (i) 97% (or such other discount as may then be in effect) of the average of the daily high and low sales prices of our Common Stock on the NYSE for the five trading days on which shares are traded immediately preceding the purchase date, or if no trading occurs in the shares of Common Stock on one or more of such days, for the five days immediately preceding the purchase date for which trades are reported, and

(ii) 97% (or such other discount as may then be in effect) of the average of the high and low sales prices of our Common Stock on the purchase date.

The high and low sales prices will be the prices as reported on the NYSE Consolidated Transaction Tape. All price calculations will be made to four decimal places. Currently, we offer a discount of 3.0% on shares purchased by dividend reinvestment directly from us. We may change the discount at any time, in our sole discretion, but the discount will always be between 0% and 5%. In the event there is no trading in the Common Stock, or if for any reason we and the Plan Administrator have difficulty in determining the price of shares to be purchased under the Plan, then we, in consultation with the Plan Administrator, will use such other public report or sources as we deem appropriate to determine the market price and the appropriate discount.

Stock Certificates and Safekeeping

13. Will I receive certificates for shares purchased through the Plan?

No. Shares of common stock acquired through the Plan are held in non-certificated, “book-entry” form. This means that paper certificates evidencing the shares of common stock that you own will not be issued. Rather, the Plan Administrator maintains an electronic account for each record holder of shares that reflects the number of shares owned by that stockholder. The number of shares credited to an account under the Plan will be shown on the participant's statement of account. This additional service protects against loss, theft or destruction of stock certificates.

14. Can I get certificates if I want them?

No.

15. May I deposit stock certificates I currently hold into my Plan account?

If you own shares of Common Stock in certificated form, you may deposit all or a portion of the certificates in your possession with the Plan Administrator for safekeeping. To deposit your stock certificates, you should send the certificates to the Plan Administrator by registered or certified mail, return receipt requested (or some other form of traceable mail), and properly insured. The insured amount represents the approximate cost to you of replacing the certificates if they are lost in transit to the Plan Administrator. The Plan Administrator will send you a statement confirming each stock certificate deposited. The Plan Administrator will credit the shares of Common Stock represented by the certificates to your account in book-entry form and will combine the shares with any whole and fractional shares then held in your Plan account.

In addition to protecting against the loss, theft or destruction of your certificates, this service also is convenient if you sell shares of Common Stock through the services of the Plan Administrator. See Question 16 for more information on how to sell your shares of Common Stock under the Plan.

The Plan Administrator charges a fee for stock certificates deposited with it for safekeeping, which fee is waived if the shares deposited are to be sold at or about the same time as the stock certificates are deposited.

Sale and Transfer of Shares

16. How can I sell shares in my Plan account?

S-12

Table of Contents

You can sell any number of shares held in your Plan account at any time by contacting the Plan Administrator. After receipt of your sale request, the Plan Administrator will sell such shares through a designated broker or dealer. The Plan Administrator will mail to you a check for the proceeds of such sale, less applicable fees described in Question 22 and any taxes. The Plan Administrator generally intends to sell shares of Common Stock at least once per day at the then current market prices through one or more brokerage firms.

Cost of Selling Shares. Please see Question 22 for a description of such fees and costs.

Termination of Your Account Upon Sale of All Shares. If you no longer hold any shares in your Plan account, the Plan Administrator may close your Plan account. Similarly, if you hold less than one share in your Plan account, the Plan Administrator may liquidate the fractional share and remit the proceeds to you, less any applicable fees, and close your Plan account.

Timing and Control. If the Plan Administrator sells your shares, we do not have the authority or power to control the timing or pricing of shares sold or the selection of the broker making the sales. Therefore, you will not be able to precisely time your sales through the Plan, and will bear the market risk associated with fluctuations in the price of shares of Common Stock. If you request the Plan Administrator to sell your shares, it is possible that the market price of shares of Common Stock could go down or up before your shares are sold, and the per share sales price you receive will be the average price of all Common Stock shares sold through the Plan Administrator with respect to that sale date. In addition, you will not earn interest on a sales transaction.

17. How can I transfer or give gifts of shares?

You may transfer or give gifts of shares of Common Stock to anyone you choose (subject to applicable law and the restrictions set forth in our Charter), by completing the transfer and other forms required by the Plan Administrator. See Question 5 for information about obtaining the necessary forms.

Note that fractional shares may only be transferred to the account of another record holder - fractional shares may not be transferred electronically to beneficial owners (as such term is used in Question 6).

18. Can I transfer my right to participate in the Plan to another person?

You may not transfer your right to participate in the Plan to another person. However, you may change ownership of all or part of your Plan shares through a gift, sale or otherwise at any time.

Termination of Participation

19. How would I terminate my participation?

You may withdraw from the Plan at any time. To do so, you must provide notice to the Plan Administrator instructing it to terminate your Plan participation. Notice may be provided by mail, telephone or through the Plan Administrator's website. To be effective for any given dividend payment, the Plan Administrator must receive notice at least three days prior to the next purchase date. If your Plan withdrawal notice is received less than three days before the next purchase date, the dividend will be applied in accordance with the Plan, but subsequent dividends will be paid to you in cash. Upon termination of your Plan account, you will receive a check for any fractional shares held in your account at the time of termination based on the current market value less any applicable service fees. After the Plan Administrator terminates your account, future dividends will be sent directly to you by check. Alternatively, if you so direct, the Plan Administrator will sell all whole and fractional shares in your Plan account and send you a check for the proceeds less any applicable fees.

Rejoining the Plan After Withdrawal. After you withdraw from the Plan, you may rejoin the Plan at any time by delivering a new Enrollment Form to the Plan Administrator. However, the Plan Administrator has the right to reject your Enrollment Form if you repeatedly join and withdraw from the Plan, or for any other reason. The Plan Administrator's exercise of this right is intended to minimize unnecessary administrative expenses and to encourage use of the Plan as a long-term stockholder investment service.

S-13

Table of Contents

Reports and Notices to Participants

20. How will I keep track of my investments?

The Plan Administrator will send you a transaction notice confirming the details of each transaction you make. If you continue to participate in the Plan but have no transactions, the Plan Administrator will send you an annual statement after the end of the year detailing the status of your holdings of shares of Common Stock in your Plan account. Participants who have elected to have their dividends reinvested will receive a quarterly Plan account statement in addition to the transaction notices.

21. Where will notices be sent?

The Plan Administrator will address all of its notices to you at your last known address. You should notify the Plan Administrator promptly, in writing, of any change of address.

Fees and Commissions

22. What are the costs of participating in the Plan?

If the Plan acquires shares directly from us, you will not pay any fees or brokerage commissions for shares of Common Stock purchased with your reinvested dividends. We have agreed to pay the Plan Administrator's fees in connection with reinvested dividends. If the Plan purchases shares in the open market or in privately negotiated transactions, you will (unless we decide in our sole and absolute discretion to pay such costs), be responsible for your pro rata share of fees and commissions, including brokerage fees, incurred in connection therewith. As of the date of this prospectus supplement, the Plan does not intend to acquire shares in the open market or through privately negotiated transactions.

If you request that the Plan Administrator sell your shares, you will pay the Plan Administrator's applicable transaction and per-share fees then in effect. Please contact the Plan Administrator for further information about these fees.

Federal Tax Consequences

23. What are the federal income tax consequences of participating in the Plan?

The following is a brief summary of the U.S. federal income tax consequences of participation in the Plan as of the date of this prospectus supplement. However, this summary does not reflect every situation that could result from participation in the Plan, and, in addition to reviewing the disclosure under the caption “Federal Income Tax Considerations” in the Base Prospectus, we advise you to consult your own tax and other advisors for information about your specific situation, including any applicable state, local or foreign income and other tax consequences that may result from your participation in the Plan. Any state tax consequences will vary from state to state, and any tax consequences to you if you reside outside of the U.S. will vary from jurisdiction to jurisdiction. This summary does not address all of the tax implications of your ownership of shares of Common Stock of a REIT, including the effect of distributions made in respect of such shares.

Under Internal Revenue Service rulings in connection with similar plans, the fair market value of the shares acquired through the Plan (including the shares acquired as a result of any Plan discount) will be taxable as dividends to the extent of our current or accumulated earnings and profits notwithstanding that such dividends are in stock. The amount of such dividends will equal the fair market value of the stock acquired with the reinvested dividends as of the date the stock is acquired under the Plan, regardless of any Plan discount.

Distributions with respect to our shares that are not designated as capital gain dividends will generally be taxable as ordinary income, and generally will not constitute "qualified dividend income" eligible to be taxed at capital gains rates for U.S. federal income tax purposes to the extent made out of our current or accumulated earnings and profits. Because we are generally not subject to U.S. federal income tax on the portion of our REIT taxable income distributed to our stockholders, our dividends generally will not be eligible for the reduced tax rate on qualified dividend income, except to the limited extent described in the tax discussion incorporated by reference or set forth in our other SEC filings. Distributions in excess of our current or accumulated earnings and profits will be treated for U.S. federal income tax purposes as a return of capital. The amount of a return of capital would first reduce the adjusted tax basis of the shares to which the distribution is attributable, with any excess treated as a taxable gain from the disposition of such shares.

S-14

Table of Contents

In the event that we designate a part or the entire amount distributed as a capital gain dividend, the amount so designated should be treated as a long-term capital gain to the extent that such distribution does not exceed our actual net capital gain for the taxable year, without regard to the period for which a stockholder has held its shares.

Your tax basis in shares of Common Stock acquired under the Plan (including the shares acquired as a result of any Plan discount) will be equal to the fair market value of such shares as of the date the shares were acquired. Your holding period for shares of Common Stock acquired under the Plan generally will commence on the day following the date on which the Common Stock is credited to your Plan account or, if the shares are purchased in the open market, the holding period will commence on the day following the date of purchase.

You will generally recognize gain or loss (which for most participants will be capital gain or loss) when you sell or exchange shares received from the Plan or when a fractional share interest is liquidated. Such gain or loss will equal the difference between the amount that you receive for such fractional share interest or such shares and your adjusted tax basis in such fractional share interest or shares.

Generally, the specific shares (and related tax basis) that are sold or exchanged will be determined on a FIFO (i.e., First In, First Out) basis. However, tax lot adjustments may be requested after a sale transaction has been completed and prior to the issuance of Form 1099-B (which generally is issued by January 31^st following the applicable tax year), by submitting a request for a tax lot adjustment and the related updated statement to HelpAST@equiniti.com and including the Company’s name, your name, your account number, the Book Lot Number(s), the share quantity, and the specific tax lot(s) to be applied. Please see “Question 5 Who will administer the Plan” for further information regarding contacting the Plan Administrator.

Certain Plan participants, including individuals, estates and trusts, may also be subject to a nondeductible 3.8% tax on the lesser of (i) "net investment income" for the taxable year, which includes, among other things, dividends on and gains from the sale or other disposition of stock, or (ii) the amount by which such participant's modified adjusted gross income for the taxable year exceeds a certain threshold amount depending on the participant's U.S. federal income tax filing status. Participants should consult with their own tax advisers regarding this tax.

In the case of foreign participants who elect to have their dividends reinvested and whose dividends are subject to United States income tax withholding, an amount equal to the dividends payable to such participants who elect to reinvest dividends, less the amount of tax required to be withheld, will be applied by the Plan Administrator to the purchase of shares of Common Stock. A Form 1042-S, mailed to each foreign participant after the final purchase of the calendar year, will show the amount of tax withheld in that year.

The foregoing is intended only as a general discussion of the current federal income tax consequences of participation in the Plan, and may not be applicable to certain participants, such as tax-exempt entities. You should consult your own tax and other professional advisors regarding the foreign, federal, state and local income tax consequences (including the effects of any changes in applicable law or interpretations thereof) of your participation in the Plan or the disposal of shares acquired pursuant to the Plan.

Other Information

24. How can I vote my shares?

You will receive proxy material for all shares in your Plan account. You may vote your shares of Common Stock either by designating the vote of the shares by proxy or by voting the shares in person at the meeting of stockholders. The proxy will be voted in accordance with your direction. If you do not return the proxy card or if you return it unsigned, none of your shares will be voted.

S-15

Table of Contents

25. Can the Plan be amended, modified, suspended or terminated?

We reserve the right to amend, modify, suspend or terminate the Plan at any time. You will receive written notice of any material amendment, modification, suspension or termination. We and the Plan Administrator also reserve the right to change any administrative procedures of the Plan.

If we terminate the Plan, we will credit your book entry account for the number of whole shares held in your Plan account and a check representing the value of any fractional shares based on the then current market price. We also will return to you any uninvested dividends held in your account.

26. How will a stock split or a rights offering affect my Plan account?

Stock Split. We will adjust your account to reflect any stock split or dividend payable in shares of Common Stock. In such event, the Plan Administrator will receive and credit to your Plan account the applicable number of whole and/or fractional shares of Common Stock.

Rights Offering. If we have a rights offering in which we issue separately tradable and exercisable rights to registered holders of shares of Common Stock, we will transfer the rights attributable to whole shares of Common Stock held in your Plan account to you as soon as practicable after we issue such rights. The Plan Administrator will sell for your account any rights attributable to fractional shares.

The Plan Administrator, at its sole discretion, may curtail or suspend transactions pending under the Plan until completion of any stock split or dividend, rights offering or other corporate action.

27. Are there any risks associated with the Plan?

Your investment in shares of Common Stock purchased under the Plan is no different from any investment in shares of Common Stock that you hold directly. Neither we nor the Plan Administrator can assure you a profit or protect you against a loss on shares that you purchase. You bear the risk of loss and enjoy the benefits of any gain from market price changes with respect to shares purchased under the Plan. We encourage you to carefully consider the various risk factors associated with an investment in our shares of Common Stock incorporated by reference into this prospectus supplement.

28. What are the responsibilities of you and the Plan Administrator?

Neither we nor the Plan Administrator will be liable for any act done in good faith or for any good faith failure to act, including, without limitation, any claim of liability (a) arising from the failure to terminate your account upon your death or judgment of incompetence prior to the Plan Administrator's receipt of notice in writing of the death or incompetence, (b) relating to the prices and times at which the Plan Administrator buys or sells shares for your account, or (c) relating to any fluctuation in the market value of the shares of Common Stock.

We, the Plan Administrator and each of our respective agents will not have any duties, responsibilities or liabilities other than those expressly set forth in the Plan or as imposed by applicable law, including Federal securities laws. Since we have delegated all responsibility for administering the Plan to the Plan Administrator, we specifically disclaim any responsibility for any of the Plan Administrator's actions or inactions in connection with the administration of the Plan. None of our directors, officers or stockholders will have any personal liability under the Plan.

The payment of dividends is at the discretion of our board of directors and will depend upon future earnings, our financial condition and other factors. The board of directors may change the amount and timing of dividends at any time without notice.

29. How will you interpret and regulate the Plan?

S-16

Table of Contents

We may interpret, regulate and take any other action in connection with the Plan that we deem reasonably necessary in our sole discretion to carry out the Plan. As a participant in the Plan, you will be bound by any actions taken by us or the Plan Administrator.

30. What law governs the Plan?

The laws of the State of Maryland govern the Plan.

USE OF PROCEEDS

We will receive the proceeds from the sale of shares of our Common Stock that the Plan Administrator purchases directly from us. We will not receive proceeds from the sale of shares of Common Stock that the Plan Administrator purchases in the open market or in negotiated transactions. We intend to use the net proceeds of the sale of any newly issued shares of Common Stock issued under the Plan for (i) the acquisition of additional multi-family properties (including equity investments in joint ventures that acquire such properties and/or the acquisition of the interest of our joint venture partners in one or more joint ventures), (ii) other direct or indirect acquisitions of, or investments in, real estate and related assets, and (iii) general corporate purposes. General corporate purposes may include, among other things, the purchase of our Common Stock, repayment of debt and capital expenditures.

We will have significant discretion in the use of any net proceeds. Investors will be relying on the judgment of our management regarding the application of the proceeds from any sale of the securities. We may invest the net proceeds temporarily until we use them for their stated purpose. We consider the Plan to be a cost-effective means of expanding our equity capital base and furthering our investment objectives while at the same time benefiting our stockholders.

PLAN OF DISTRIBUTION

Except to the extent the Plan Administrator purchases shares of Common Stock in the open market or in negotiated transactions, we will sell directly to you through the Plan Administrator the shares of Common Stock acquired under the Plan. The shares of Common Stock may be resold in market transactions on any national securities exchange on which shares of our Common Stock trade or in privately negotiated transactions. Our shares of Common Stock are currently listed on the New York Stock Exchange.

Persons who acquire shares of Common Stock through the Plan and resell them shortly after acquiring them, including coverage of short positions, under certain circumstances, may be participating in a distribution of securities that would require compliance with Regulation M under the Exchange Act, and may be considered to be underwriters within the meaning of the Securities Act. We will not extend to any such person any rights or privileges other than those to which it would be entitled as a participant under the Plan, nor will we enter into any agreement with any such person regarding such person's purchase of such shares or any resale or distribution thereof.

Subject to the restrictions contained in our Charter, our by-laws, and the availability of shares of Common Stock registered for issuance under the Plan, there is no maximum number of shares of Common Stock that can be purchased by a stockholder pursuant to the reinvestment of dividends. In connection with any reinvestment of dividends in which the Plan Administrator purchases shares of Common Stock in the open market or negotiated transactions, you will pay your pro rata share of any trading fees. You also will have to pay any fees and commissions set forth in Question 22 of the Plan.
