                        RULE 14D-1 TENDER OFFER STATEMENT

         Introduction

         This Amendment No. 3 amends and supplements the Tender Offer Statement
on Schedule TO originally filed on November 15, 2002, as amended (the "Schedule
TO") by American Realty Investors, Inc. ("ARL") and Income Opportunity
Acquisition Corporation, a wholly-owned subsidiary of ARL ("IOT Acquisition
Sub"). This Schedule TO includes the Schedule 13E-3 Transaction Statement of ARL
and IOT Acquisition Sub.

         This Tender Offer Statement relates to the offer by IOT Acquisition Sub
to purchase any and all of the issued and outstanding shares of common stock of
Income Opportunity Realty Investors, Inc. ("IOT") for $19.00 net per share in
cash upon the terms and subject to the conditions set forth in the Offer to
Purchase, dated November 15, 2002 and filed as Exhibit (a)(1) to the Schedule
TO. The information set forth in the Offer to Purchase and the Letter of
Transmittal (filed as Exhibit (a)(2) to the Schedule TO), including all
schedules, exhibits and annexes thereto, is hereby expressly incorporated herein
by reference in response to all items of information required to be included in,
or covered by, this Tender Offer Statement on Schedule TO and all items of
information required to be included in, or covered by, the Schedule 13E-3
Transaction Statement. The responses to each item in this Tender Offer Statement
are qualified in their entirety by the information contained in the Offer to
Purchase and the exhibits, as amended, hereto.

ITEM 1. SUMMARY TERM SHEET.

         Item 1 of the Schedule TO is hereby amended as follows:

         IOT Acquisition Sub is extending the expiration date of its offer to
         purchase any and all of the issued and outstanding shares of common
         stock of IOT. The original expiration date for the tender offer was
         12:00 Midnight December 13, 2002. As extended, the tender offer will
         now expire at 12:00 p.m. New York City time, on Friday, December 20,
         2002. IOT stockholders have until the newly-extended expiration date to
         decide whether to tender their IOT shares in the offer. As of 3:00 P.M.
         New York City time on Friday, December 13, 2002, approximately 252,174
         shares of IOT common stock, or approximately 17.2% of the outstanding
         shares, had been tendered and not withdrawn pursuant to the tender
         offer.

ITEM 4. TERMS OF THE TRANSACTION.

         Item 4 of the Schedule TO is hereby amended as follows:

ITEM 13. INFORMATION REQUIRED BY SCHEDULE 13E-3.

         Item 1. Summary Term Sheet is hereby amended as follows:

                  See Item 1 of this Tender Offer Statement.

         Items 4. Terms of the Transaction is hereby amended as follows:

                  See Item 1 of this Tender Offer Statement.

         Item 8. Fairness of the Transaction is hereby amended as follows:

         The following is added after the bullet point on page 24 of the Offer
to Purchase:

         o        The ARL board did not consider the liquidation value or the
                  going concern value of IOT in reaching its fairness
                  determination because it did not have available to it a
                  current liquidation analysis of IOT, or any analysis of the
                  going concern value thereof beyond the value assigned by the
                  ongoing market for IOT's shares. Further, the ARL board did
                  not believe that liquidation of IOT was a realistic
                  alternative.

         o        The ARL board did not consider the purchase prices of IOT
                  common stock paid by its affiliates in the prior two years to
                  be a material factor in its fairness determination because the
                  purchases were made in the open market at market prices, the
                  prices paid were below the offer price and the offer price was
                  determined pursuant to the court-approved Settlement
                  Agreement. See "Special Factors - Overview of the Lawsuit and
                  Settlement Agreement that Led to this Tender Offer."

         o        The ARL board was not aware of any firm offers made by any
                  unaffiliated person during the past two years for the merger
                  or consolidation of IOT with any other company, the sale or
                  other transfer of all or any substantial part of the assets of
                  IOT or a purchase of IOT's stock that would enable the holder
                  to exercise control of IOT and, therefore, did not consider
                  any such offers in its fairness determination.

         o        The offer does not require the approval of IOT stockholders.
                  Each stockholder will determine whether to tender or not and
                  the offer is not dependent upon a vote of stockholders. No
                  stockholder will be compelled to sell in the offer. In the
                  event there is a follow-on merger after the expiration of the
                  offer, ARL intends to seek the approval of at least a majority
                  of unaffiliated IOT stockholders. The ARL board believes the
                  offer is procedurally fair despite the absence of approval of
                  at least a majority of stockholders because the terms of the
                  offer were negotiated by Settlement Counsel representing the
                  IOT stockholders as part of the Settlement Agreement and
                  because no stockholder is required to accept the offer. See
                  "Special Factors - Overview of the Lawsuit and Settlement
                  Agreement that Led to this Tender Offer."

         o        The IOT board did not retain an unaffiliated representative to
                  act solely on behalf of the unaffiliated stockholders for
                  purposes of negotiating the terms of the offer or preparing a
                  report concerning fairness. The ARL board believes the offer
                  is procedurally fair despite the absence of such a
                  representative because the terms of the offer were negotiated
                  by Settlement Counsel representing the IOT stockholders





                  as part of the Settlement Agreement and because IOT has a
                  board of directors that reviewed and approved the Settlement
                  Agreement. See "Special Factors - Overview of the Lawsuit and
                  Settlement Agreement that Led to this Tender Offer."

         o        The ARL board was aware that BCM may receive fees, currently
                  estimated to be $1,939,000, in connection with the sale of any
                  property that may be sold and loans that may be obtained to
                  finance the purchase of shares in the offer. The ARL board did
                  not consider this fact material when making its determination
                  of fairness because the price was determined in arms-length
                  negotiations with Settlement Counsel representing the IOT
                  stockholders as part of the negotiations that led to the
                  Settlement Agreement. See "Special Factors - Overview of the
                  Lawsuit and Settlement Agreement that Led to this Tender
                  Offer."

         The words "procedural and substantive" are added before the word
         "fairness" in the first sentence of the last paragraph on page 24 of
         the Offer to Purchase.

         The words "procedurally and substantively" are added before the word
         "fairness" in the last sentence of the last paragraph on page 24 of the
         Offer to Purchase.





                                    SIGNATURE

         After due inquiry and to the best of my knowledge and belief, I certify
that the information is set forth in this statement is true, complete and
correct.
