                         AMENDMENT NO. 1 TO SCHEDULE TO

         This Amendment No. 1 amends and supplements the Tender Offer Statement
and Rule 13e-3 Transaction Statement on Schedule TO initially filed on November
8, 2004 (the "Schedule TO"). This Amendment No. 1 relates to the offer by AIMCO
Properties, L.P., a Delaware limited partnership, to purchase units of limited
partnership interest ("Units") of Consolidated Capital Properties IV, a
California limited partnership (the "Partnership"), at a price of $181.82 per
unit in cash, subject to the conditions set forth in the Litigation Settlement
Offer dated November 8, 2004 and in the related Letter of Transmittal (which,
together with any supplements or amendments, collectively constitute the
"Offer"). Copies of the Litigation Settlement Offer and the Letter of
Transmittal are filed with the Schedule TO as Exhibits (a)(1) and (a)(2),
respectively. The item numbers and responses thereto below are in accordance
with the requirements of Schedule TO, and all section and page references are to
the Litigation Settlement Offer. Unless defined herein, capitalized terms used
and not otherwise defined herein, and all section and page references are to the
Litigation Settlement Offer. have the respective meanings ascribed to such terms
in the Litigation Settlement Offer.

         On December 1, 2004, AIMCO Properties, L.P. issued a press release
announcing the extension of the expiration date of the Offer from midnight, New
York City time, on December 8, 2004 to midnight, New York City time, on December
15, 2004. A copy of that press release has been filed as Exhibit (a)(4) to this
Amendment No. 1.

ITEM 1. SUMMARY TERM SHEET.

         The information incorporated by reference into Item 1 of the Schedule
TO is amended and supplemented as follows:

         (1) The first paragraph of the second bullet point beginning with "The
         Settlement Fund" under "SUMMARY TERM SHEET" on page 1 is amended by
         adding the following to the end thereof:

         "In addition, if you requested exclusion from the settlement but tender
         your units, by signing the letter of transmittal, you will release us
         from claims that you would otherwise have preserved by requesting
         exclusion from the settlement class. If you did not request exclusion,
         you will release any known or unknown claims arising out of the class
         and derivative litigation if the judgment approving the settlement is
         affirmed on appeal. By executing the enclosed letter of transmittal,
         moreover, you will release those claims even if the judgment is
         reversed or otherwise vacated on appeal. See "--Release and Assignment
         of Future Claims" below."

ITEM 4. TERMS OF THE TRANSACTION.

         The information incorporated by reference into Item 4(a) of the
Schedule TO is amended and supplemented as follows:

         (1) The third bullet point on the front cover of the Litigation
         Settlement Offer is amended by replacing the second sentence with the
         following:

         "We determined our offer price by estimating a net equity value for
         your partnership units based on an aggregate gross property value of
         $139,130,877 (equal to 106% of the aggregate value determined by the
         independent appraisal in 2003), reduced by estimated prepayment
         penalties of $8,483,965, resulting in an aggregate net property value
         of $130,691,912. The aggregate gross property value is the sum of the
         gross property value for each of your partnership's properties as
         estimated by us, before reduction for any prepayment penalties."

         (2) The fourth risk factor entitled, "OUR OFFER PRICE MAY NOT REFLECT
         THE FAIR VALUE OF YOUR PARTNERSHIP'S PROPERTIES" under "RISK FACTORS"
         on page 5 is amended by replacing the first sentence with the
         following:

         "We determined our offer price by estimating a net equity value for
         your partnership units based on an aggregate gross property value of
         $139,130,877 (equal to 106% of the aggregate value determined by the
         independent appraisal in 2003), reduced by estimated prepayment
         penalties of $8,483,965, resulting in an aggregate net property value
         of $130,691,912. The aggregate gross property value is the sum of the
         gross property value for each of your partnership's properties as
         estimated by us, before reduction for any prepayment penalties."

         (3) The risk factor entitled, "WE COULD DELAY ACCEPTANCE OF, AND
         PAYMENT FOR, YOUR UNITS" under "RISK FACTORS" on page 8 is amended by
         adding the following to the end thereof:

         "We will pay for or return tendered units promptly after expiration of
         the offer."



                                       3



         (4) "Section 6. Material Federal Income Tax Matters" is amended by
         adding the following to the end thereof on page 19:

                  "Tax Consequences to the General Partner of Your Partnership
         and its Affiliates, including AIMCO Properties, L.P. The sale of your
         units pursuant to this offer will not be a taxable transaction for the
         general partner of your partnership or its affiliates, including AIMCO
         Properties, L.P. Consequently, the general partner of your partnership
         and its affiliates will not recognize gain or loss in connection with
         this offer. We intend to treat the entire offer price as consideration
         paid to you for your units, regardless of whether you requested
         exclusion from the settlement. We, like any other purchaser of units,
         will receive a tax basis in the purchased units equal to the
         consideration paid by us for the units. This tax basis will be
         allocated over the assets owned by your partnership, and we will be
         able to take depreciation and amortization deductions to the extent
         basis is allocated to depreciable or amortizable property owned by your
         partnership."

         (5) "Section 7. Effects of the Offer" is amended by adding the
         following before the paragraph entitled "Accounting Treatment" on page
         20:

                  "Costs Associated with Being a Public Company. There are
         various costs associated with being a public company, including costs
         associated with preparing, auditing and filing our periodic reports
         with the SEC. We estimate these expenses to be approximately $53,000
         per year. This represents approximately 4% of the partnership's general
         and administrative expenses and 0.25% of the partnership's total
         expenses (based on 2003 expenses of approximately $1,334,000 and
         $21,134,000, respectively). In addition, as a result of the
         Sarbanes-Oxley Act of 2002, we estimate our costs will increase by
         approximately 10% beginning in 2005. If the partnership were to
         terminate its registration under the Exchange Act, the estimated cost
         savings would be approximately $53,000 per year."

         (6) The section entitled "Determination of Offer Price" under "Section
         8. Valuation of Units" beginning on page 20 up to, but not including,
         the table on page 23 immediately preceding the section entitled
         "Comparison of Offer Price to Alternative Consideration" is amended and
         restated as follows:

                  "Determination of Offer Price. We determined our offer price
         by estimating the liquidation proceeds that would be payable to limited
         partners if calculating a net equity value of units of limited
         partnership interest based on a valuation of your partnership's
         properties. Our starting point in this process was the value of each of
         your partnership's properties as determined by the court-appointed,
         independent appraiser in 2003. For a more a detailed description of the
         independent appraisals of your partnership's properties, see "The
         Litigation Settlement Offer -- Section 8. Valuation of Units; Estimated
         Liquidation Proceeds Based on Independent Appraisal."

                  For The Apartments, we assigned it a gross property value of
         $7,000,000, which is equal to its appraised value.

                  For Arbours of Hermitage Apartments, we assigned it a gross
         property value of $15,000,000, which is equal to its appraised value.

                  For Belmont Place Apartments (formerly Chimney Hill
         Apartments), we assigned it a gross property value of $10,000,000 after
         considering the value of completed redevelopment activities on the
         property. The appraisal was for $2,900,000 and reflected the value of
         the land only.

                  For Briar Bay Racquet Club, we assigned it a gross property
         value of $18,315,900, which is equal to 90% of its sales price of
         $20,254,000. The appraised value was $12,500,000.

                  For Citadel Apartments, we assigned it a gross property value
         of $7,554,977, which is equal to 94% of its appraised value. We made
         this determination based on certain factors, including the following:

                  - the property's vacancy rate for the month ended July 2004
                  was 5% and its loss rate was 12%, as compared to a vacancy and
                  loss rate of 8% projected by the appraiser;

                  - our assessment of recent housing trends in the local market
                  in which the property is located; and

                  - our assessment of the general economic outlook for the area
                  in which the property is located.


                                       4


                 For Citadel Village Apartments, we assigned it a gross property
         value of $4,950,000, which is equal to 90% of its appraised value. We
         made this determination based on certain factors, including the
         following:

                  - the property's vacancy rate for the month ended July 2004
                  was 3% and its loss rate was 41%, as compared to a vacancy and
                  loss rate of 13.5% projected by the appraiser;

                  - the property has offered fairly significant concessions in
                  order to obtain its 3% vacancy rate. The property's effective
                  gross income for the twelve months ended June 30, 2004 was
                  approximately $776,000 compared to a projected annual
                  effective gross income of $982,757 by the appraiser;

                  - our assessment of recent housing trends in the local market
                  in which the property is located; and

                  - our assessment of the general economic outlook for the area
                  in which the property is located.

              For Foothill Place Apartments, we assigned it a gross property
         value of $21,500,000, which is equal to its appraised value.

              For Knollwood Apartments, we assigned it a gross property value of
         $14,800,000, which is equal to its appraised value.

              For Lake Forest Apartments, we assigned it a gross property value
         of $10,980,000, which is equal to 90% of its appraised value. We made
         this determination based on certain factors, including the following:

                  - the property's loss rate for the month ended July 2004 was
                  11%, as compared to a loss rate of 8% projected by the
                  appraiser;

                  - our assessment of recent housing trends in the local market
                  in which the property is located; and

                  - our assessment of the general economic outlook for the area
                  in which the property is located.

              For Nob Hill Villa Apartments, we assigned it a gross property
         value of $9,630,000, which is equal to 90% of its contracted sales
         price of $10,700,000. The appraised value from 2003 was $12,400,000.

              For Post Ridge Apartments, we assigned it a gross property value
         of $7,400,000, which is equal to its appraised value.

              For Rivers Edge Apartments, we assigned it a gross property value
         of $7,500,000, which is equal to its appraised value.

              For Village East Apartments, we assigned it a gross property value
         of $4,500,000, which is equal to 90% of its appraised value. We made
         this determination based on certain factors, including the following:

                  - the property's vacancy rate for the month ended July 2004
                  was 8% and its loss rate was 50%, as compared to a vacancy and
                  loss rate of 18% projected by the appraiser;


                                       5


                  - the appraisal assumed the loss rate would improve over a
                  24-month period as the property leased up. The lease up has
                  been slower than anticipated;

                  - our assessment of recent housing trends in the local market
                  in which the property is located; and

                  - our assessment of the general economic outlook for the area
                  in which the property is located.

              We then deducted from the gross property values estimated
         prepayment penalties of $1,457,257 for The Apartments, $185,059 for
         Arbours of Hermitage Apartments, $114,639 for Briar Bay Racquet Club,
         $1,812,524 for Citadel Apartments, $80,247 for Citadel Village
         Apartments, $330,814 for Foothill Place Apartments, $222,071 for
         Knollwood Apartments, $2,380,811 for Lake Forest Apartments, $810,254
         for Post Ridge Apartments, $974,868 for Rivers Edge Apartments and
         $70,421 for Village East Apartments, respectively, to determine their
         net property values. The following table compares the appraised values
         of your partnership's properties to the net property values that we
         used to determine our offer price:

</Table>


              The aggregate net property value for all of your partnership's
         properties is $130,691,912. This is determined by aggregating the net
         property values of all properties. After determining the aggregate net
         property value, we then calculated a net equity value for your
         partnership based on such aggregate net property value by adding the
         value of the non-real estate assets of your partnership and deducting
         its liabilities, including mortgage debt and debt owed by your
         partnership to the general partner or its affiliates.

              Finally, we allocated 100% of this net equity value to limited
         partners, which is the percentage of net proceeds that would be paid to
         limited partners in the event of a liquidation of your partnership. Our
         offer price represents the net equity value per unit determined in this
         manner, plus a pro rata portion of the settlement fund, as indicated
         below."

         (7) The first line of the table on page 23 immediately preceding the
         section entitled "Comparison of Offer Price to Alternative
         Consideration" under "Section 8. Valuation of Units - Determination of
         Offer Price" is amended by replacing "Aggregate gross property value of
         partnership properties" with "Aggregate net property value of
         partnership properties".

         (8) "Section 8. Valuation of Units - Estimated Liquidation Proceeds
         Based on Independent Appraisal" on page 24 is amended by replacing the
         first paragraph with the following:

                  "Selection and Qualifications of Independent Appraiser. Your
         partnership's property was appraised by American Appraisal Associates,
         Inc. ("AAA"), an independent appraiser appointed by the court. Under
         the terms of the settlement, the independent appraiser was required to
         provide in writing its professional opinion as to the market value of
         each of the partnership's properties as of the date of the delivery of
         the written appraisal, describing the methodologies used and other
         information which the appraiser deemed appropriate to support or
         explain its work. The appraiser was also required to prepare an
         executive summary of each appraisal that included all material
         information. As the appraiser was court-appointed, no special valuation
         instructions were given to the appraiser by the partnership, us or our
         affiliates. The information set forth below was provided to us by AAA
         with respect to its appraisals."


                                       6


         (9) The paragraph entitled, "Summary of Independent Appraisals of Your
         Partnership's Property" on page 28 under "Section 8. Valuation of Units
         - Estimated Liquidation Proceeds Based on Independent Appraisal" is
         amended by replacing the last sentence with the following:

         "The estimated total "as is" market value of the fee simple estate of
         your partnership's property is $131,700,000, which was determined by
         adding the estimated values determined by AAA for each of your
         partnership's properties and which is higher than the aggregate net
         property value of $130,691,912 as estimated by us."

         (10) The second bullet point on page 74 under "Section 19. Conditions
         to the Offer" is amended by replacing items "(v)" through "(vii)" with
         the following:

         "(v) any limitation (whether or not mandatory) by any governmental
         authority on, or any other material event which, in either case, could
         reasonably be expected to affect the extension of credit by banks or
         other lending institutions, or (vi) in the case of any of the foregoing
         existing at the time of the commencement of the offer, a material
         acceleration or worsening thereof; or"

         (11) The first sentence of the last paragraph on page 75 under "Section
         19. Conditions to the Offer" is amended by replacing the first sentence
         with the following:

                  "The foregoing conditions are for our sole benefit and may be
         asserted by us regardless of the circumstances (other than
         circumstances arising out of actions or inactions by us or our
         affiliates) giving rise to such conditions or may be waived by us at
         any time in our reasonable discretion prior to the expiration of this
         offer."

ITEM 12. EXHIBITS.

         Item 12 of the Schedule TO is amended and supplemented as follows:

         (a)(4) Press Release dated December 1, 2004.



                                       7


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

         ITEM 7. PURPOSES, ALTERNATIVES, REASONS AND EFFECTS.

              The information incorporated by reference into Item 7(d) of
         Item 13 of the Schedule TO is amended and supplemented as follows:

              (1) "Section 6. Material Federal Income Tax Matters" is amended by
              adding the following to the end thereof on page 19:

                       "Tax Consequences to the General Partner of Your
              Partnership and its Affiliates, including AIMCO Properties, L.P.
              The sale of your units pursuant to this offer will not be a
              taxable transaction for the general partner of your partnership or
              its affiliates, including AIMCO Properties, L.P. Consequently, the
              general partner of your partnership and its affiliates will not
              recognize gain or loss in connection with this offer. We intend to
              treat the entire offer price as consideration paid to you for your
              units, regardless of whether you requested exclusion from the
              settlement. We, like any other purchaser of units, will receive a
              tax basis in the purchased units equal to the consideration paid
              by us for the units. This tax basis will be allocated over the
              assets owned by your partnership, and we will be able to take
              depreciation and amortization deductions to the extent basis is
              allocated to depreciable or amortizable property owned by your
              partnership."

              (2) "Section 7. Effects of the Offer" is amended by adding the
              following before the paragraph entitled "Accounting Treatment" on
              page 20:

                       "Costs Associated with Being a Public Company. There are
              various costs associated with being a public company, including
              costs associated with preparing, auditing and filing our periodic
              reports with the SEC. We estimate these expenses to be
              approximately $53,000 per year. This represents approximately 4%
              of the partnership's general and administrative expenses and 0.25%
              of the partnership's total expenses (based on 2003 expenses of
              approximately $1,334,000 and $21,134,000, respectively). In
              addition, as a result of the Sarbanes-Oxley Act of 2002, we
              estimate our costs will increase by approximately 10% beginning in
              2005. If the partnership were to terminate its registration under
              the Exchange Act, the estimated cost savings would be
              approximately $53,000 per year."

         ITEM 9. REPORTS, OPINIONS, APPRAISALS AND NEGOTIATIONS.

              The information incorporated by reference into Item 9(b) of
         Item 13 of the Schedule TO is amended and supplemented as follows:

              (1) "Section 8. Valuation of Units - Estimated Liquidation
              Proceeds Based on Independent Appraisal" on page 24 is amended by
              replacing the first paragraph with the following:

                       "Selection and Qualifications of Independent Appraiser.
              Your partnership's property was appraised by American Appraisal
              Associates, Inc. ("AAA"), an independent appraiser appointed by
              the court. Under the terms of the settlement, the independent
              appraiser was required to provide in writing its professional
              opinion as to the market value of each of the partnership's
              properties as of the date of the delivery of the written
              appraisal, describing the methodologies used and other information
              which the appraiser deemed appropriate to support or explain its
              work. The appraiser was also required to prepare an executive
              summary of each appraisal that included all material information.
              As the appraiser was court-appointed, no special valuation
              instructions were given to the appraiser by the partnership, us or
              our affiliates. The information set forth below was provided to us
              by AAA with respect to its appraisals."

              (2) The paragraph entitled, "Summary of Independent Appraisals of
              Your Partnership's Property" on page 28 under "Section 8.
              Valuation of Units - Estimated Liquidation Proceeds Based on
              Independent Appraisal" is amended by replacing the last sentence
              with the following:

              "The estimated total "as is" market value of the fee simple estate
              of your partnership's property is $131,700,000, which was
              determined by adding the estimated values determined by AAA for
              each of your partnership's properties and which is higher than the
              aggregate net property value of $130,691,912 as estimated by us."
