DBRS Morningstar Finalizes Provisional Ratings on AMSR 2023-SFR4 Trust

DBRS, Inc. (DBRS Morningstar) finalized its provisional ratings on the Single-Family Rental Pass-Through Certificates (the Certificates) to be issued by AMSR 2023-SFR4 Trust (AMSR 2023-SFR4):

-- $76.5 million Class A at AAA (sf)
-- $44.1 million Class B at AA (high) (sf)
-- $3.9 million Class C at AA (sf)
-- $7.8 million Class D at A (high) (sf)
-- $28.5 million Class E-1 at BBB (sf)
-- $6.1 million Class E-2 at BBB (low) (sf)
-- $11.2 million Class F at BB (sf)

The AAA (sf) rating on the Class A Certificates reflects 60.9% of credit enhancement provided by subordinated notes in the pool. The AA (high) (sf), AA (sf), A (high) (sf), BBB (sf), BBB (low) (sf), BB (sf), and BB (low) (sf) ratings reflect 38.3%, 36.3%, 32.3%, 22.6%, 17.7%, 14.6%, and 8.9% of credit enhancement, respectively.

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

The AMSR 2023-SFR4 Certificates are supported by the income streams and values from 832 rental properties. The properties are distributed across 15 states and 29 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 broker price opinion value, 37.2% of the portfolio is concentrated in three states: Missouri (14.1%), Arizona (13.0%), and Georgia (10.1%). The average property value is $268,313. The average age of the properties is roughly 46 years. The majority of the properties have three or more bedrooms. The certificates represent a beneficial ownership in an approximately four-year, fixed-rate, interest-only loan with an initial aggregate principal balance of approximately $195.3 million.

The sponsor intends to satisfy its risk-retention obligations under the U.S. Risk Retention Rules. The sponsor does not make any representation with respect to whether such risk retention satisfies EU Risk Retention Requirements and UK Risk Retention Requirements by retaining Class G, which is 6.3% of the initial total issuance balance, either directly or through a majority-owned affiliate.

DBRS Morningstar finalized 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 www.dbrsmorningstar.com.) 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 rate, 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 the 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 in the DBRS Morningstar presale report.) DBRS Morningstar also conducted a legal review and found no material rating concerns. (For details, see the Scope of Analysis section in the DBRS Morningstar presale report.)

DBRS Morningstar’s credit ratings on the Certificates address the credit risk associated with the identified financial obligations in accordance with the relevant transaction documents. The associated financial obligations for each of the rated Certificates are the related Interest Distribution Amounts, Deferral Rate Interest Distribution Amounts, and Principal Distribution Amounts.

DBRS Morningstar’s credit ratings do not address nonpayment risk associated with contractual payment obligations contemplated in the applicable transaction document(s) that are not financial obligations.

DBRS Morningstar’s long-term credit ratings provide opinions on risk of default. DBRS Morningstar considers risk of default to be the risk that an issuer will fail to satisfy the financial obligations in accordance with the terms under which a long-term obligation has been issued.
