Origen Financial Announces Preliminary Unaudited Year-End Results and
Schedules Formal Earnings Release and Conference Call

     SOUTHFIELD, MI. (February 23, 2005) — Origen Financial, Inc. (NASDAQ: ORGN), a real estate investment trust that originates and services manufactured home loans, today announced its preliminary unaudited financial results for the year ended December 31, 2004. The information in this press release reflects Origen’s preliminary unaudited year-end results. Origen’s final year-end results and the payment amount of a fourth quarter dividend will be discussed in greater detail in an earnings release to be distributed on March 14, 2005 and in an earnings conference call to be held on March 15, 2005.

     Sun Communities, Inc. (NYSE: SUI), a publicly-traded company that owns approximately 20% of Origen’s common stock, is an “accelerated filer,” meaning that it is required to report its earnings before Origen. To facilitate Sun Communities’ accurate financial reporting of its ownership interest in Origen, and to ensure that Origen’s investors have the most accurate information available, Origen has released its unaudited earnings.

     Origen announced a net loss of $1.77 million, or $0.08 per share on a weighted-average, fully-diluted basis, for the year ended December 31, 2004. Origen also announced a net loss of $5.76 million, or $0.23 per share on a weighted-average, fully-diluted basis, for the quarter ended December 31, 2004.

     The net losses for the year and the fourth quarter are primarily the result of an increase in Origen’s reserves for recourse obligations on certain pre-2002 loans and restructuring and related relocation costs associated with an 8% overall personnel reduction in the fourth quarter.

     As indicated in previous press releases, Origen has observed increases in late-stage delinquencies on loans originated before 2002. Many of these loans were sold with recourse by a predecessor of Origen. As a consequence of these continuing higher delinquencies on sold loans, Origen decided to increase its recourse reserves to reflect the anticipated future losses with respect to these loans. After the adjustment to the recourse loss reserve, on a going-forward

basis, Origen does not expect to experience any significant increases in its provision for recourse reserves with respect to these loans. Were it not for the loan loss adjustment, Origen would have reported positive net income for 2004.

Earnings Call and Webcast

     A conference call and webcast are scheduled for March 15, 2005, at 11:00 a.m. EST to discuss 2005 financial results. Registration for the conference call and webcast can be made through Origen’s website at www.origenfinancial.com. The toll-free call-in number for Q&A is 800-289-0496.
