      Item 8.01.  Other Events

            Computational Materials

            Origen Residential Securities, Inc. (the "Registrant") anticipates
      that it will issue a series of notes entitled Origen Manufactured Housing
      Contract Trust Collateralized Notes, Series 2005-A (the "Notes"), to be
      issued pursuant to an indenture, dated as of May 1, 2005, among Origen
      Manufactured Housing Contract Trust 2005-A, as issuer, and JPMorgan Chase
      Bank, N.A., as trustee. The Notes will be collateralized by a trust estate
      (the "Trust Estate") consisting primarily of all of the issuer's right,
      title and interest in and to certain manufactured housing installment
      sales contracts and installment loan agreements (the "Contracts"),
      including, without limitation, all related security interests and any and
      all rights to receive payments which are due pursuant thereto after the
      applicable cut-off date, but excluding any rights to receive payments
      which are due pursuant thereto on or before the applicable cut-off date.

            Citigroup Global Markets Inc. (the "Underwriter") has advised the
      Registrant that it has furnished to certain prospective purchasers of
      Notes certain materials, herein referred to as "Computational Materials,"
      in written form, which Computational Materials are in the nature of data
      tables and term sheet information relating to the Contracts or other
      assets of the Trust Estate, the structure of the Notes and terms of
      certain classes of Notes, and the hypothetical characteristics and
      hypothetical performance of certain classes of Notes under certain
      assumptions and scenarios.

            The Computational Materials have been provided by the Underwriter.
      The information in the Computational Materials is preliminary and will be
      supplemented by a prospectus supplement relating to the Notes and by any
      other information subsequently filed with the Securities and Exchange
      Commission.

            The Computational Materials were prepared by the Underwriter at the
      request of certain prospective investors. The Computational Materials may
      be based on information that differs from the information set forth in the
      related prospectus supplement.
