ITEM 1.  SECURITY AND ISSUER

         This Amendment No. 24 to Statement on Schedule 13D relates to the
shares of Common Stock, par value $0.01 per share (the "Shares") of INCOME
OPPORTUNITY REALTY INVESTORS, INC., a Nevada corporation ("IOT" or the "Company"
or the "Issuer") and further amends the original Statement on Schedule 13D as
amended by Amendment Nos. 1 through 23 thereof (the "Amended Statement") filed
by and on behalf of the "Reporting Persons" described below. The principal
executive offices of the Company are located at 1800 Valley View Lane, Suite
300, Dallas, Texas 75234. The CUSIP number of the Shares is 452926-10-8.

         This Amendment No. 24 to Schedule 13D is being filed to reflect various
changes in the information contained in the Amended Statement, including the
disposition through certain transactions of a total of 781,773 Shares by certain
of the Reporting Persons which resulted in the beneficial ownership of the
Reporting Persons being decreased by approximately 54.3% of the number of Shares
of the Issuer outstanding.

ITEM 2.  IDENTITY AND BACKGROUND

         Item 2 of the Amended Statement is hereby further amended as follows:

         This Amendment is being filed on behalf of American Realty Investors,
Inc., a Nevada corporation ("ARL"), its wholly-owned subsidiaries, Income
Opportunity Acquisition Corporation, a Nevada corporation ("IOT AcqSub"),
American Realty Trust, Inc., a Georgia corporation ("ART"), and its wholly-owned
subsidiary, EQK Holdings, Inc., a Nevada corporation ("EQK"), Basic Capital
Management, Inc., a Nevada corporation ("BCM"), IOT AcqSub and Transcontinental
Realty Investors, Inc., a Nevada corporation ("TCI"), each of which have their
principal executive offices located at 1800 Valley View Lane, Suite 300, Dallas,
Texas 75234. All of ARL, ART, EQK, IOT AcqSub, BCM and TCI are collectively
referred to as the "Reporting Persons." The Reporting Persons may be deemed to
constitute a "person" within the meaning of Section 13(d) of the Securities
Exchange Act of 1934, as amended, because (i) EQK is a wholly-owned subsidiary
of ART. ART and IOT AcqSub are each wholly-owned subsidiaries of ARL, (ii) BCM
owns approximately 76.2% of the outstanding securities of ARL, and (iii) BCM
serves as the Advisor to ARL and TCI.

         On May 23, 2003, ARL issued a press release announcing that ARL's Board
of Directors determined that it was not in the best interest of ARL to continue
to pursue previously proposed mergers of IOT and TCI into subsidiaries of ARL.
As a result, ARL requested the consent of the Securities and Exchange Commission
(the "SEC") to ARL's withdrawal of its Registration Statement on Form S-4 (No.
333-83292) relating to the issuance of ARL stock in connection with the proposed
mergers which request effectively terminates such proposed mergers. All
references in the Amended Statement to such proposed mergers are now deleted.

                                      -1-

         by Reporting Persons and                                          =======                     =====
         individua listed above:


         (b) Each of the directors of TCI have shared voting and dispositive
power over the 345,728 Shares held by TCI.

         (c) During the 60 calendar days ended June 2, 2003, the Reporting
Persons and their respective executive officers and directors did not engage in
any transaction in the Shares or any other equity interest derivative thereof
except as follows:

                  (i) On March 18, 2003, IOT AcqSub purchased 265,036 Shares
         pursuant to a cash tender offer at $19 per share (a total of
         $5,035,684) the consideration for which came from the working capital
         of IOT AcqSub.

                  (ii) On June 2, 2003, IOT AcqSub distributed as a dividend to
         ARL all 265,036 Shares at a value of $19 per share.

                  (iii) On June 2, 2003, ARL made a contribution to the capital
         of ART of the 265,036 Shares received from IOT AcqSub

                                      -2-



         at a value of $19 per share, and ART in turn made a contribution to the
         capital of EQK of the same 265,036 Shares at a value of $19 per share
         which, when added together with the 409,935 Shares held by EQK resulted
         in EQK holding a total of 674,971 Shares.

                  (iv) Pursuant to a Stock Transfer Agreement dated June 2, 2003
         (the "Transfer Agreement") between EQK and BCM, EQK sold to BCM, and
         BCM acquired from EQK, 674,971 Shares at a purchase price of $18.45 per
         share (a total of $12,453,214) for which BCM paid and delivered to EQK
         (x) 650,000 shares of TCI at a price of $18.35 per share (a total of
         $11,972,500), and (y) BCM's promissory note payable to the order of EQK
         in the stated principal amount of $525,714 bearing interest and payable
         as set forth therein (the "BCM Note"). The BCM Note bears interest at
         the Wall Street Journal prime rate plus 2% per annum, is unsecured and
         matures on June 30, 2004. The result of such transaction was that BCM
         acquired 674,971 Shares which, together with the 106,802 Shares held by
         BCM resulted in BCM owning and holding a total of 781,773 Shares
         (approximately 54.3% of the issued and outstanding IOT Shares).

                  (v) On June 2, 2003, BCM entered into a Stock Purchase
         Agreement with Syntek West, Inc., a Nevada corporation ("SWI"),
         pursuant to which BCM sold to SWI all 781,773 Shares at a price of
         $18.45 per share in cash (a total of $14,423,711), the purchase price
         for which was paid by SWI crediting the principal balance outstanding
         on a promissory note issued by BCM payable to the order of SWI in the
         stated principal amount of $21,000,000, which bears interest at the
         Wall Street Journal prime rate plus 2% per annum and matures on June
         30, 2004.

After giving effect to the foregoing transactions, each of IOT AcqSub, ARL, ART
and BCM ceased to be the holder of any Shares of IOT, leaving only TCI as a
Reporting Person holding and owning 345,728 Shares which constitute
approximately 24% of the total issued and outstanding IOT Shares.

         (d) No person other than the Reporting Person or its respective Board
of Directors is known to have the right to receive or the power to direct
receipt of dividends from, or the proceeds of sale of, the Shares held by each
of the Reporting Persons, subject to the matters set forth in Item 6 below.

         (e) After giving effect to the transactions occurring on June 2, 2003,
among IOT AcqSub, ARL, ART, EQK and BCM, IOT AcqSub, ARL, ART, EQK and BCM each
cease to be the holder of any Shares of IOT, and cease to be the beneficial
owners of more than 5% of the shares of IOT, leaving only TCI as a Reporting
Person holding and owning 345,728 Shares which represent approximately 24% of
the issued and outstanding IOT Shares. Therefore, the date on which IOT AcqSub,
ARL, ART, EQK and BCM ceased

                                      -3-


to be the beneficial owners of more than 5% of the Shares was June 2, 2003.
