Exhibit 33.3

Managements Assertion

Management of First Republic Bank (the Bank) is responsible for assessing compliance with the applicable servicing criteria set forth in Item 1122(d) of
Regulation AB of the Securities and Exchange Commission relating to the servicing of residential mortgage loans serviced for others (the Platform), except for the servicing criteria 1122(d)(1)(iii), 1122(d)(3)(i)(C) and 1122d(4)(xv), which the Bank
has determined are not applicable to the activities it performs with respect to the Platform, as of and for the year ended December 31, 2017. Appendix A identifies the individual asset-backed transactions and securities defined by management as
constituting the Platform.

With respect to servicing criteria 1122(d)(4)(iv), 1122(d)(4)(xi) and 1122(d)(4)(xii), management has engaged various vendors
to perform the activities required by these servicing criteria. The Banks management has determined that none of these vendors is considered a servicer as defined in Item 1101(j) of Regulation AB, and the Banks management has
elected to take responsibility for assessing compliance with the servicing criteria applicable to each vendor as permitted by the SECs Compliance and Disclosure Interpretation (C&DI) 200.06, Vendors Engaged by Servicers(C&DI 200.06). Management has policies and procedures in place designed to provide reasonable assurance that the vendors activities comply in all material respects with the servicing criteria applicable to each vendor. The Banks
management is solely responsible for determining that it meets the SEC requirements to apply C&DI 200.06 for the vendors and related criteria.

The
Banks management has assessed the Banks compliance with the applicable servicing criteria as of and for the year ended December 31, 2017. In making this assessment, management used the criteria set forth by the Securities and
Exchange Commission in paragraph (d) of Item 1122 of Regulation AB.

Based on such assessment, management believes that, as of and for the year ended
December 31, 2017, the Bank has complied in all material respects with the servicing criteria set forth in Item 1122(d) of Regulation AB of the Securities and Exchange Commission relating to the servicing of the Platform.

KPMG LLP, an independent registered public accounting firm, has issued an attestation report with respect to the Banks compliance with the applicable
servicing criteria as of and for the year ended December 31, 2017.
