Exhibit 34.5

[Ernst & Young LLP Letterhead]

Report of Independent Registered Public Accounting Firm

Board of Directors

SunTrust Mortgage, Inc.

We have examined managements assertion, included in the accompanying Certification Regarding Compliance with Applicable Servicing Criteria, that SunTrust
Mortgage, Inc. (the Company) complied with the servicing criteria set forth in Item 1122 (d) of the Securities and Exchange Commissions Regulation AB for the residential mortgage loan servicing platform, except for the instances of
material noncompliance described therein, as of and for the year ended December 31, 2013, and except for criteria 1122(d)(1)(iii), 1122(d)(4)(i), 1122(d)(4)(ii) and 1122(d)(4)(xv), which the Company has determined are not applicable to the
activities performed by them with respect to the servicing platform covered by this report. See Appendix B of managements assertion for the asset backed transactions covered by this platform. Management is responsible for the Companys
compliance with those servicing criteria. Our responsibility is to express an opinion on managements assertion about the Companys compliance with the servicing criteria based on our examination.

Our examination was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants, as adopted by the
Public Company Accounting Oversight Board (United States) and, accordingly, included examining, on a test basis, evidence about the Companys compliance with the applicable servicing criteria and performing such other procedures as we
considered necessary in the circumstances. Our examination included testing of less than all of the individual asset backed transactions and securities that comprise the platform, testing of less than all of the servicing activities related to the
platform and determining whether the Company processed those selected transactions and performed those selected activities in compliance with the servicing criteria. Furthermore, our procedures were limited to the selected transactions and servicing
activities performed by the Company during the period covered by this report. Our procedures were not designed to determine whether errors may have occurred either prior to or subsequent to our tests that may have affected the balances or amounts
calculated or reported by the Company during the period covered by this report for the selected transactions or any other transactions. We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a
legal determination on the Companys compliance with the servicing criteria.

Our examination disclosed the following material noncompliance with
servicing criteria 1122(d)(2)(v), 1122(d)(4)(vi), and 1122(d)(4)(vii) applicable to the Company during the year ended December 31, 2013:



| |  |  | 1122(d)(2)(v)  Certain custodial accounts were not maintained in accordance with the transaction agreements.
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | 1122(d)(4)(vi)  Certain loan modifications were not made, reviewed or approved in accordance with the transaction agreements.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | 1122(d)(4)(vii)  Certain loss mitigation actions or recovery actions were not initiated, conducted and/or concluded in accordance with timeframes or other requirements established by the transaction agreements.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The information in the accompanying Certification Regarding Compliance with Applicable Servicing Criteria, under
Appendix C, regarding remediation activities is presented by the Company for information purposes. Such information has not been subjected to the procedures applied in our examination of managements assertion as described above and
accordingly, we express no opinion on it.

In our opinion, except for the material non-compliance described in the third paragraph, the Company complied,
in all material respects, with the aforementioned servicing criteria as of and for the year ended December 31, 2013.
