February 15, 2023

DBRS, Inc. (DBRS Morningstar) assigned the following provisional ratings to the Single-Family Rental Pass-Through Certificates (the Certificates) to be issued by AMSR 2023-SFR1 Trust (AMSR 2023-SFR1):

-- $185.1 million Class A at AAA (sf)
-- $48.1 million Class B at AA (high) (sf)
-- $23.4 million Class C at AA (low) (sf)
-- $32.1 million Class D at A (low) (sf)
-- $24.7 million Class E-1 at BBB (high) (sf)
-- $24.7 million Class E-2 at BBB (low) (sf)
-- $40.7 million Class F at BB (sf)

The AAA (sf) rating on the Class A Certificate reflects 55.09% of credit enhancement provided by subordinated notes in the pool. The AA (high) (sf), AA (low) (sf), A (low) (sf), BBB (high) (sf), BBB (low) (sf), and BB (sf) ratings reflect 43.41%, 37.72%, 29.94%, 23.95%,17.96%, and 8.08% credit enhancement, respectively.

Other than the classes specified above, DBRS Morningstar does not rate any other classes in this transaction.

The Certificates are supported by the income streams and values from 1,655 rental properties. The properties are distributed across 14 states and 31 metropolitan statistical areas (MSAs) in the U.S. DBRS Morningstar maps an MSA based on the ZIP code provided in the data tape, which may result in different MSA stratifications than those provided in offering documents. As measured by BPO value, 45.0% of the portfolio is concentrated in three states: Florida (19.8%), Georgia (12.9%), and Texas (12.3%). The average value is $298,234. The average age of the properties is roughly 37 years. The majority of the properties have three or more bedrooms. The Certificates represent a beneficial ownership in an approximately five-year, fixed-rate, interest-only loan with an initial aggregate principal balance of approximately $412.1 million.

The Sponsor intends to satisfy its risk-retention obligations under the U.S. Risk Retention Rules, EU Risk Retention Requirements, and UK Risk Retention Requirements by Class G, which is 6.8% of the initial total issuance balance, either directly or through a majority-owned affiliate.

DBRS Morningstar assigned the provisional ratings for each class of Certificates by performing a quantitative and qualitative collateral, structural, and legal analysis. This analysis uses DBRS Morningstar’s single-family rental subordination analytical tool and is based on DBRS Morningstar’s published criteria. (For more details, see DBRS Morningstar developed property-level stresses for the analysis of single-family rental assets. DBRS Morningstar assigned the provisional ratings to each class based on the level of stresses each class can withstand and whether such stresses are commensurate with the applicable rating level. DBRS Morningstar's analysis includes estimated base-case net cash flows (NCFs) by evaluating the gross rent, concession, vacancy, operating expenses, and capital expenditure data. The DBRS Morningstar NCF analysis resulted in a minimum debt service coverage ratio of more than 1.0 times. (For more details, see the Analysis section in DBRS Morningstar presale report.)

Furthermore, DBRS Morningstar reviewed the third-party participants in the transaction, including the property manager, servicer, and special servicer. These transaction parties are acceptable to DBRS Morningstar. (For more details, see the Property Manager and Servicer Summary section.) DBRS Morningstar also conducted a legal review and found no material rating concerns. (For details, see the Scope of Analysis section.)
