The Company is responsible for the specified attributes identified by the Company in the Data File.

The Specified Parties have agreed to and acknowledged that the procedures performed are appropriate to meet their intended purpose of assisting specified parties in evaluating the accuracy of the specified attributes in the Data File. This report may not be suitable for any other purpose. No other parties have agreed to or acknowledged the appropriateness of these procedures for the intended purpose or any other purpose.

The procedures performed may not address all the items of interest to a specified party of this report and may not meet the needs of all specified parties of this report and, as such, specified parties are responsible for determining whether the procedures performed are appropriate for their purposes. We make no representation regarding the appropriateness of the procedures either for the intended purpose or for any other purpose.

Unless otherwise stated, the following definitions have been adopted in presenting our procedures and findings:

• The term “compared” means compared to the information shown and found it to be in agreement, unless otherwise stated. Such compared information was deemed to be in agreement if differences were within the reporting threshold.

• The term “recomputed” means recalculated and compared the result to the information shown and found it to be in agreement, unless otherwise stated. Such recomputed information was deemed to be in agreement if differences were within the reporting threshold.

• The term “reporting threshold” means that dollar amounts, percentages, and number of days were within $1.00, 0.1%, and 30 days, respectively.

• The term “Cutoff Date” means October 31, 2023.

• The term “Source Documents” means the following information provided by the Company for each of the Selected Loans (defined below): (i) sales contract, (ii) credit report, and (iii) Company’s servicing system screenshots listed in electronic data file entitled “Copy of SENT–- SAFCO 2024-1 Exceptions SAFCO Responses 12.5.2023 (002).xlsx” received on December 11, 2023 (the “Servicing System Screenshots”).

• The term “Instructions” means the instructions provided by the Company pertaining to a procedure, attribute, or methodology, as described in the “Source Documents/Instructions” column of Exhibit B.

• The term “Provided Information” means the Cutoff Date, Source Documents, and Instructions.

The procedures we were instructed by the Company to perform and the associated findings are as follows:

A. We randomly selected a sample of 125 Loans from the Data File (the “Selected Loans”). A listing of the Selected Loans is attached hereto as Exhibit A. For purposes of this procedure, the Company did not inform us of the basis they used to determine the number of Loans we were instructed to randomly select from the Data File.

B. For each Selected Loan, we compared or recomputed the specified attributes in the Data File listed in Exhibit B to or using the corresponding information included in the Source Documents, utilizing the Instructions, as applicable. The Specified Parties indicated that the absence of any of the information in the Source Documents or the inability to agree the indicated information from the Data File to the Source Documents for each of the attributes identified, utilizing the Instructions as applicable, constituted an exception. The Source Documents are listed in the order of priority.

We found such information to be in agreement except as listed in Exhibit C.

We were engaged by the Company to perform this agreed-upon procedures engagement and conducted our engagement in accordance with attestation standards established by the American Institute of Certified Public Accountants, which involves us performing the specific procedures agreed to and acknowledged above and reporting on findings based on performing those procedures. We were not engaged to, and did not, conduct an examination or review, the objective of which would be the expression of an opinion or conclusion, respectively, on the specified attributes in the Data File. Accordingly, we do not express such an opinion or conclusion. Had we performed additional procedures, other matters might have come to our attention that would have been reported.

We are required to be independent of the Company and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements related to our agreed-upon procedures engagement.

The procedures performed were applied based on the information included in the Data File and Provided Information, without verification or evaluation of such information by us; therefore, we express no opinion or any other form of assurance regarding (i) the reasonableness of the information provided to us by the Company, (ii) the physical existence of the Loans, (iii) the reliability or accuracy of the Provided Information which was used in our procedures, or (iv) matters of legal interpretation.

The procedures performed were not intended to address, nor did they address: (i) the conformity of the origination of the Loans to stated underwriting or credit extension guidelines, standards, criteria or other requirements, (ii) the value of collateral securing any such Loan being securitized, (iii) the compliance of the originator of the Loans with federal, state, and local laws and regulations, or (iv) any other factor or characteristic of the Loans that would be material to the likelihood that the issuer of the asset-backed securities will pay interest and principal in accordance with applicable terms and conditions. The procedures performed were not intended to satisfy any criteria for due diligence published by the nationally recognized statistical rating organizations (“NRSROs”).

The terms of our engagement are such that we have no responsibility to update this report because of events and circumstances that may subsequently occur.

This report is intended solely for the information and use of the Specified Parties.
