Substitute information provided in accordance with General Instruction J to Form 10K:

None.

Item 1114(b)(2) of Regulation AB: Credit Enhancement and Other Support, Except for Certain Derivatives Instruments (Financial Information).

None.

Item 1115(b) of Regulation AB: Certain Derivatives
Instruments (Financial Information).

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-S2 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.



---

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.

Item 1119 of Regulation AB: Affiliations and Certain Relationships
and Related Transactions.

Information contemplated by Item 1119 of Regulation AB has been omitted from this report in reliance on the
Instruction to Item 1119.

Item 1122 of Regulation AB: Compliance with Applicable Servicing Criteria.

Each of Residential Funding, GMACM, Homecomings Financial, LLC (Homecomings), Wachovia Mortgage Corporation, First American Real Estate Solutions of Texas,
L.P., ZC Sterling Insurance Agency, Inc., 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.



---

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.



---

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 



| |  |  | 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
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.

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.
