Based  on the  standards  set  forth  in  Item  1115(b)  of  Regulation  AB,  no
information is required in response to this Item.

ITEM 1117 OF REGULATION AB: LEGAL PROCEEDINGS.

There are no material pending legal or other proceedings  involving the mortgage
loans or Residential Funding Company,  LLC ("Residential  Funding"),  as sponsor
and master  servicer,  Residential  Funding  Mortgage  Securities  I,  Inc.,  as
depositor, RFMSI Series 2007-S1 Trust, as the issuing entity, GMAC Mortgage, LLC
("GMACM"), as subservicer, or other parties described in Item 1117 of Regulation
AB that, individually or in the aggregate,  would have a material adverse impact
on investors in the securities (the "Securities") to which this report relates.


<PAGE>


Residential Funding and GMACM are currently parties to various legal proceedings
arising from time to time in the ordinary  course of their  businesses,  some of
which purport to be class actions. Based on information currently available,  it
is the opinion of Residential Funding and GMACM that the eventual outcome of any
currently pending legal proceeding,  individually or in the aggregate,  will not
have a material adverse effect on their ability to perform their  obligations in
relation to the mortgage  loans.  No assurance,  however,  can be given that the
final outcome of these legal proceedings, if unfavorable, either individually or
in the  aggregate,  would not have a  material  adverse  impact  on  Residential
Funding  or GMACM.  Any such  unfavorable  outcome  could  adversely  affect the
ability of  Residential  Funding or GMACM to perform its  servicing  duties with
respect  to the  mortgage  loans  and  potentially  lead to the  replacement  of
Residential Funding or GMACM with a successor servicer.

Among  the  legal  proceedings  to  which  Residential  Funding  is a party is a
putative class action lawsuit that was filed against a lender (Mortgage  Capital
Resources Corporation),  Residential Funding and other parties in state court in
Kansas City,  Missouri.  Plaintiffs  asserted  violations of the Missouri Second
Mortgage  Loan Act  ("SMLA"),  Mo.R.S.  Section  408.233,  based on the lender's
charging or  contracting  for payment of allegedly  unlawful  closing  costs and
fees.  The relief sought  included a refund of all allegedly  illegal fees,  the
refund of interest paid, and the discounted present value of interest to be paid
in the future on active mortgage loans.  The plaintiffs also sought  prejudgment
interest and punitive damages.

Residential  Funding is an assignee of some of the  mortgage  loans in question.
The plaintiffs  contended that  Residential  Funding is strictly  liable for the
lender's alleged SMLA violations pursuant to the assignee provisions of the Home
Ownership  and Equity  Protection  Act of 1994,  15 U.S.C.  Section  1641(d)(1).
Residential  Funding  terminated its  relationship  with the lender in early May
2000.

In connection with that  proceeding,  on January 4, 2008, a verdict was returned
that Residential  Funding pay $4.33 million in actual damages and $92 million in
punitive damages.  Residential  Funding intends to appeal and vigorously contest
the punitive  damage award.  However,  even if the punitive  damage award is not
reduced  upon  appeal,   Residential  Funding's  management  believes  that  any
liability  with  respect to this  proceeding  would not have a material  adverse
effect on investors in the Securities.

Information  contemplated  by Item 1119 of  Regulation  AB has been omitted from

ITEM 1122 OF REGULATION AB: COMPLIANCE WITH APPLICABLE SERVICING
CRITERIA.

Each of Residential Funding, GMACM,  Homecomings Financial, LLC ("Homecomings"),
U.S. Bank National Association and Wells Fargo Bank, National Association (each,
a "Servicing  Participant")  has been  identified  by the  registrant as a party
participating in the servicing  function with respect to the pool assets held by
the Issuing Entity.  Reports  assessing  compliance with the servicing  criteria
applicable to each Servicing  Participant  (each, a "Report on Assessment")  are
attached as exhibits  to this Form 10-K.  In  addition,  an  attestation  report
(each,  an  "Attestation  Report")  regarding each Report on Assessment has been
prepared by the related Servicing  Participant's  registered  independent public
accounting firm and is attached as an exhibit to this Form 10-K.


<PAGE>


Residential  Capital,  LLC,  which  owns  indirectly  all of the  equity of both
Homecomings and GMACM, has restructured the operations of Homecomings and GMACM.
As a result of the restructuring -

   (i) on May 1, 2007, the computer system on which  Homecomings  maintained its
      servicing  platform  was  transferred  from one system  (LSAMS) to another
      system (MortgageServ) on which its affiliate GMACM maintains its servicing
      platform; and

   (ii) on September 24, 2007,  Homecomings  transferred its servicing  platform
      and certain employees responsible for the servicing function to GMACM.

Since  September  24, 2007,  GMACM has serviced the mortgage  loans owned by the
trust that were  previously  serviced by  Homecomings,  and  Homecomings has not
serviced any of those mortgage loans.

As a result of the integration of the Homecomings and GMACM servicing  platforms
on a single computer system as described in clause (i) above -

   (x) the Report on Assessment and related Attestation Report filed as Exhibits
      33.3 and 34.3 to this Form 10-K address  Homecomings'  compliance with the
      applicable servicing criteria for the pre-platform integration period from
      January 1, 2007 through April 30, 2007; and

   (y) the Report on Assessment and related Attestation Report filed as Exhibits
      33.2 and 34.2 to this Form 10-K  address (1) GMACM's  compliance  with the
      applicable servicing criteria for the pre-platform integration period from
      January 1, 2007 through April 30, 2007, and (2) each of  Homecomings'  and
      GMACM's  compliance  with  the  applicable   servicing  criteria  for  the
      post-platform  integration  period from May 1, 2007  through  December 31,
      2007.

Vendors

A Servicing  Participant may engage one or more vendors to perform  specific and
limited,  or scripted  activities  that  address all or a portion of one or more
servicing criteria applicable to such Servicing Participant. In general in these
cases,  the Servicing  Participant  has  instituted  policies and  procedures to
monitor whether such vendors'  activities  comply in all material  respects with
such  servicing  criteria,  and may elect to take  responsibility  for assessing
compliance with the servicing criteria applicable to such vendors' activities in
such  Servicing   Participant's  Report  on  Assessment.   Where  the  Servicing
Participant  has not  instituted  such  policies  and  procedures,  or where the
Servicing  Participant  does  not  otherwise  elect to take  responsibility  for
assessing its vendors'  activities,  the vendor is itself treated as a Servicing
Participant  and is required to provide its own Report on Assessment and related
Attestation Report.


<PAGE>


Exceptions

Except as disclosed below, no Report on Assessment or related Attestation Report
has identified  (i) any material  instance of  noncompliance  with the servicing
criteria  identified  in such Report on  Assessment as applicable to the related
Servicing  Participant  or  (ii)  any  material  deficiency  in  such  Servicing
Participant's policies and procedures to monitor vendor compliance.

GMAC Mortgage,  LLC: The Report on Assessment  prepared by GMACM and the related
Attestation Report have identified  material  noncompliance with two elements of
one servicing criterion applicable to it. Specifically, with regard to servicing
criterion 1122(d)(2)(vii),  which contemplates that reconciliations are prepared
on a monthly basis for all asset-backed securities related bank accounts -

   o  certain  custodial  account  reconciliations  were not reviewed within the
      timelines outlined in GMACM's policies and procedures,  as contemplated by
      criterion 1122(d)(2)(vii)(C); and

   o  certain  custodial  accounts had reconciling items which were not resolved
      within 90 calendar days of original  identification,  as  contemplated  by
      criterion 1122(d)(2)(vii)(D).

The registrant  does not believe these instances of  noncompliance  had material
impacts or effects on  investors,  and  appropriate  measures have been taken to
resolve the bank reconciliation items noted in the Report on Assessment,  and to
prevent such instances of  noncompliance in the future or to detect them in such
a manner as to permit prompt correction.

Homecomings Financial, LLC: The Report on Assessment prepared by Homecomings and
the related Attestation Report have identified  material  noncompliance with one
servicing  criterion  applicable to it.  Specifically,  with regard to servicing
criterion  1122(d)(4)(x)(C),  certain refunds resulting from payoff transactions
were not returned to the obligor  within 30 calendar  days of full  repayment of
the related pool asset, as  contemplated by such criterion.  The registrant does
not believe these instances of noncompliance  had material impacts or effects on
investors, and appropriate measures have been taken to prevent such instances of
noncompliance  in the  future  or to  detect  them in such a manner as to permit
prompt correction.

Platform-Level Reports

Regulations of the Securities and Exchange  Commission  (the "SEC") require that
each  Servicing  Participant  complete a Report on  Assessment  at a  "platform"
level,  meaning that the transactions covered by the Report on Assessment should
include  all  asset-backed  securities  transactions  involving  such  Servicing
Participant  that are backed by the same asset type.  Further  guidance from the
SEC staff identifies  additional  parameters  which a Servicing  Participant may
apply to define  and  further  limit its  platform.  For  example,  a  Servicing
Participant  may define its  platform  to include  only  transactions  that were
completed  on or after  January  1, 2006 and that were  registered  with the SEC
pursuant  to  the  Securities  Act  of  1933.  Each  Servicing   Participant  is
responsible  for defining its own platform,  and each  platform  will  naturally
differ based on various factors,  including the Servicing Participant's business
model,  the  transactions  in which it is involved  and the range of  activities
performed in those transactions.


<PAGE>


Based on our understanding of their platforms and the guidance that is available
at this time, we believe that the parameters by which the Servicing Participants
have defined their platforms should be permissible.  However,  because the SEC's
regulations  are new and the guidance  that is available at this time is subject
to clarification or change, we cannot assure you that the SEC and its staff will
necessarily agree.

ITEM 1123 OF REGULATION AB: SERVICER COMPLIANCE STATEMENT.

Each of Residential Funding, GMACM and Homecomings (each, a "Servicer") has been
identified by the  registrant as a servicer with respect to the pool assets held
by the Issuing Entity. Each Servicer has provided a statement of compliance with
its  obligations  under the servicing  agreement  applicable to such Servicer (a
"Compliance  Statement") for the portion of the period covered by this Form 10-K
during which such Servicer was servicing the pool assets, in each case signed by
an authorized officer of such Servicer. Each Compliance Statement is attached as
an exhibit to this Form 10-K.  None of the Compliance  Statements has identified
any instance  where the related  Servicer has failed to fulfill its  obligations
under the applicable servicing agreement in any material respects.
