Introductory Note

     This Amendment No. 34 (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. and AIMCO/IPT, Inc. (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, Century Properties Fund XVII, LP, a Delaware limited partnership (the “Partnership”), entered into an agreement and plan of merger (the “Merger Agreement”) with AIMCO Properties and AIMCO CPF XVII 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 Series A unit of limited partnership interest (each, a “Series A Unit”) of the Partnership outstanding immediately prior to the consummation of the merger (other than Series A Units held by limited partners who perfect their appraisal rights pursuant to the Merger Agreement) will be converted into the right to receive either (i) $311.18 per Series A Unit in cash or (ii) a number of partnership common units of AIMCO Properties calculated by dividing $311.18 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 Series A Units of the Partnership. As a result, after the merger, AIMCO Properties will own all outstanding Series A Units. The Series B units of limited partnership interest of the Partnership will not be affected by the merger and will remain outstanding following consummation of the merger.

     Completion of the merger is subject to certain conditions, including approval by a majority in interest of the limited partners holding Series A Units. As of July 21, 2011, the Partnership had issued and outstanding 75,000 Series A Units, and AIMCO Properties and its affiliates owned 52,866 of those Series A Units, or approximately 70.49% of the number of outstanding Series A Units. 25,833.5 of the Series A Units owned by AIMCO IPLP, L.P., an affiliate of Fox Partners and of AIMCO Properties, are subject to a voting restriction, which requires such Series A Units to be voted in proportion to the votes cast with respect to Series A Units not subject to this voting restriction. AIMCO Properties and its affiliates have indicated that they will vote all of their Series A Units that are not subject to the voting restriction described above (27,032.5 or approximately 36.04% of the outstanding Series A Units) in favor of the merger. As a result, AIMCO Properties and its affiliates will vote a total of 41,236 Series A Units, or approximately 54.98% of the outstanding Series A 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.

Item 5. Interest in Securities of the Issuer

     Item 5 is hereby amended and restated in its entirety as follows:

     (a)-(b) The information in rows (7) through (11) and (13) of each Reporting Person’s cover page is incorporated herein by reference.
