The AAA (sf) rating on the Class A Certificate reflects 57.8% of credit enhancement provided by subordinated notes in the pool. The AA (high) (sf), A (high) (sf), A (low) (sf), BBB (sf), BBB (low) (sf), BB (high) (sf), and BB (low) (sf) ratings reflect 46.5%, 40.7%, 33.4%, 26.5%, 21.3%, 13.2%, and 6.3% credit enhancement, respectively.

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

The AMSR 2021-SFR4 certificates are supported by the income streams and values from 2,239 rental properties. The properties are distributed across seven states and 17 metropolitan statistical areas (MSAs) in the United States. 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, 64.4% of the portfolio is concentrated in three states: Florida (26.1%), North Carolina (21.0%), and Georgia (17.2%). The average value is $301,373. The average age of the properties is roughly 21 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 $583.0 million.

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 model and is based on DBRS Morningstar’s published criteria. 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 flow (NCF) 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 higher than 1.0 times.

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. DBRS Morningstar also conducted a legal review and found no material rating concerns.
