Item 1. Security and Issuer

     The name of the issuer is Consolidated Capital Properties IV, a Delaware limited partnership (the “Partnership”), and the address of its principal executive offices is 4582 South Ulster Street Parkway, Suite 1100, Denver, Colorado 80210. The title of the class of equity securities to which this statement relates are the units of limited partnership interest of the Partnership (the “Units”).

     This Amendment No. 31 (this “Amendment”) amends Item 4 of the Statement on Schedule 13D filed previously by AIMCO Properties, L.P. or certain of its affiliates.

Item 4. Purpose of Transaction.

     Item 4 is hereby amended by adding the following paragraphs:

     ConCap Equities, Inc. is the general partner (the “General Partner”) of the Partnership. The General Partner is an affiliate of the Reporting Persons. The Partnership owns a 99% interest in Foothill Chimney Associates Limited Partnership, a Georgia limited partnership (the “Operating Partnership”). The Operating Partnership owns Belmont Place Apartments (“Belmont”), a 326-unit apartment complex located in Marietta, Georgia. On September 29, 2008, the Operating Partnership and one other partnership that together own two apartment complexes containing an aggregate of 1,046 apartment units entered into an Agreement for Purchase and Sale and Joint Escrow Instructions, as amended on October 2, 2008 (the “Purchase Agreement”) with third parties, JRK Property Holdings, Inc., a California corporation, and JRK Birchmont Advisors, LLC, a Delaware limited liability company (collectively, the “Purchaser”), to sell the two apartment complexes to the Purchaser for a total sales price of $75,200,000, $35,200,000 of which is to be allocated to Belmont (the “Transaction”).

     Upon the completion of the sale of the Property, the Partnership will continue to conduct its business.

     The Transaction must be approved by the General Partner and a majority in interest of the limited partners of the Partnership. The General Partner’s affiliates (including the Reporting Persons), which own a majority of the outstanding units of limited partnership interests in the Partnership, have indicated that they intend to take action by written consent to approve the Transaction. As a result, approval of the Transaction is assured, and no other limited partner’s consent to the Transaction would be required.
