Introductory Note

This Amendment No. 33 (this “Amendment”) amends the Statement on Schedule 13D (as amended, the “Statement”) previously filed with the Securities and Exchange Commission by AIMCO Properties, L.P. (“AIMCO Properties”), AIMCO-GP, Inc., Apartment Investment and Management Company, AIMCO IPLP, L.P., AIMCO/IPT, Inc. and IPLP Acquisition I LLC (collectively, the “Reporting Persons”).

Item 4. Purpose of Transaction

Item 4 is hereby supplemented by the addition of the following information:

On July 28, 2011, Consolidated Capital Properties IV, LP, a Delaware limited partnership (the “Partnership”), entered into an agreement and plan of merger (the “Merger Agreement”) with AIMCO Properties and AIMCO CCP IV Merger Sub LLC, a Delaware limited liability company of which AIMCO Properties is the sole member (the “Merger Subsidiary”), pursuant to which the Merger Subsidiary will be merged with and into the Partnership, with the Partnership as the surviving entity.

In the merger, each unit of limited partnership interest (each, a “Unit”) of the Partnership outstanding immediately prior to the consummation of the merger (other than Units held by limited partners who perfect their appraisal rights pursuant to the Merger Agreement), will be converted into the right to receive, at the election of the limited partner, either (i) $57.44 per Unit in cash or (ii) a number of partnership common units of AIMCO Properties calculated by dividing $57.44 by the average closing price of Apartment Investment and Management Company common stock, as reported on the New York Stock Exchange, over the ten consecutive trading days ending on the second trading day immediately prior to the effective time of the merger. In the merger, AIMCO Properties’ membership interest in the Merger Subsidiary will be converted into Units of the Partnership. As a result, after the merger, AIMCO Properties will be the sole limited partner of the Partnership and will own all outstanding Units.

Completion of the merger is subject to certain conditions, including approval by a majority in interest of the limited partners holding Units. AIMCO Properties and its affiliates own approximately 69.4% of the outstanding Units and have indicated that they intend to take action by written consent to approve the merger.

The Merger Agreement may be terminated, and the merger may be abandoned, at any time prior to consummation of the merger by the Partnership, AIMCO Properties or the Merger Subsidiary for any reason, and there is no assurance that the merger will be consummated.
