Mail Stop 4561 July 13, 2005 Kathryn L. Hale Chief Financial Officer Amerivest Properties Inc. 1780 South Bellaire Street, Suite 100 Denver, Colorado 80222 	Re:	Amerivest Properties Inc. 		Form 10-K for Fiscal Year Ended December 31, 2004 		Form 10-Q for Fiscal Quarter Ended March 31, 2005 		File No. 1-14462 Dear Ms. Hale: We have reviewed your response letter dated July 8, 2005 and have the following additional comments. These comments should be addressed in all future filings. Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filing. We look forward to working with you in these respects. We welcome any questions you may have about our comments or on any other aspect of our review. Feel free to call us at the telephone numbers listed at the end of this letter. Form 10-K for Fiscal Year Ended December 31, 2004 Management`s Discussion and Analysis of Financial Condition and Results of Operations, page 29 Results of Operations, page 30 Same Store Property Results 1. We note your proposed disclosure in response to our comment. Because same store net operating income is not determined on a basis consistent with the consolidated income statement, it is not reasonably possible to reconcile this information to a comparable GAAP performance measure. You may continue to include discussions of same store revenues and expenses within the context of discussing your operating results in your MD&A, but please remove discussions of same store net operating income as it not reconcilable to a GAAP measure. Further to the extent that you present net operating income on a consolidated basis, please ensure that you discuss how management uses this information and why this measure is useful to an investor as required by Item 10(e) of Regulation S-K. Please respond to the comments included in this letter within ten business days. If you have any questions, you may contact Thomas Flinn, Staff Accountant, at (202) 551-3469 or the undersigned at (202) 551-3498 if you have questions. 			Sincerely, Cicely D. Luckey Accounting Branch Chief Ms. Kathryn L. Hale Amerivest Properties Inc. July 13, 2005 Page 1
