DBRS Morningstar Finalizes Provisional Ratings on AMSR 2021-SFR1 Trust

DBRS, Inc. (DBRS Morningstar) finalized its provisional ratings on the following Single-Family Rental Pass-Through Certificates (the Certificates) issued by AMSR 2021-SFR1 Trust (AMSR 2021-SFR1):

-- $118.6 million Class A at AAA (sf)
-- $60.0 million Class B at AA (sf)
-- $16.7 million Class C at A (high) (sf)
-- $21.6 million Class D at A (low) (sf)
-- $18.6 million Class E-1 at BBB (high) (sf)
-- $25.5 million Class E-2 at BBB (low) (sf)
-- $50.0 million Class F at BB (low) (sf)
-- $33.3 million Class G at B (low) (sf)

The AAA (sf) rating on the Class A Certificates reflects 67.6% of credit enhancement provided by subordinated notes in the pool. The AA (sf), A (high) (sf), A (low) (sf), BBB (high) (sf), BBB (low) (sf), BB (low) (sf), and B (low) (sf) ratings reflect 53.7%, 49.2%, 43.3%, 38.2%, 31.3%, 17.6% and 8.6% credit enhancement, respectively.

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

AMSR 2021-SFR1 Trust's (AMSR 2021-SFR1 or the Issuer) 1,706 properties are in 12 states, with the largest concentration by BPO value in Florida (42.4%). The largest MSA by value is Atlanta (12.6%), followed by Orlando (12.0%). The geographic concentration dictates the home-price stresses applied to the portfolio and the resulting market value decline (MVD). The MVD at the AAA (sf) rating level for this deal is 61.2%. AMSR 2021-SFR1 has properties from 36 MSAs, most of which did not experience home-price index (HPI) declines as dramatic as those in the recent housing downturn.

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 model 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 finalized 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 NCFs by evaluating the gross rent, concession, vacancy, operating expenses, and capital expenditure (capex) data. The DBRS Morningstar NCF analysis resulted in a minimum DSCR of higher than 1.0 times (x).

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.
