Residential Funding Mortgage Securities I, Inc.

Ladies and Gentlemen:

     We have acted as your counsel in connection with the authorization and
issuance from time to time in one or more series of Mortgage Pass-Through
Certificates (the "Certificates"). We have examined the Registration Statement
on Form S-3 dated as of January 20, 2006 relating to the Certificates (the
"Registration Statement"), the prospectus (the "Prospectus") forming a part of
the Registration Statement to be filed with the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Act"), and such other documents as we have deemed necessary or advisable for
purposes of rendering this opinion. As set forth in the Registration Statement,
separate trusts (each, a "Trust") will be established and will issue
Certificates pursuant to a pooling and servicing agreement (collectively the
"Agreement"). Except as otherwise indicated herein, all terms defined in the
Prospectus are used herein as so defined.

     We have assumed for the purposes of the opinions set forth below that the
Certificates will be issued in series created as described in the Registration
Statement and that the Certificates will be sold by you for reasonably
equivalent consideration. We have also assumed that the Agreement and the
Certificates will be duly authorized by all necessary corporate action and that
the Certificates will be duly issued, executed, authenticated and delivered in
accordance with the provisions of the Agreement. In addition, we have assumed
that the parties to each Agreement will satisfy their respective obligations
thereunder. We express no opinion with respect to any series of Certificates for
which we do not act as counsel to you.

     On the basis of the foregoing examination and assumptions, and upon
consideration of applicable law, it is our opinion that when an Agreement for a
series of Certificates has been duly and validly authorized, executed and
delivered by the parties thereto, and the Certificates of such series have been
duly executed, authenticated, delivered and sold as contemplated in the
Registration Statement, such Certificates will be legally and validly issued,
fully paid and nonassessable, and the holders of such Certificates will be
entitled to the benefits of such Agreement.



     We hereby consent to the filing of this letter as an exhibit to the
Registration Statement and to the references to this firm under the headings
"Legal Matters" in the Prospectus and "Legal Opinions" in the Prospectus
Supplement forming a part of the Registration Statement, without admitting that
we are "experts" within the meaning of the term used in the Act or the rules and
regulations of the Commission issued thereunder, with respect to any part of the
Registration Statement, including this exhibit or otherwise.

                                        Very truly yours,


                                        /s/ MAYER, BROWN, ROWE & MAW LLP
