KBRA downgrades the ratings of four classes and affirms all other ratings for GSMS 2017-485L, a CMBS SASB transaction. The rating actions follow a surveillance review of the transaction, which has exhibited a decline in performance since KBRA’s last review and securitization, primarily as a result of lease rollover, which has caused a decrease in occupancy from 99.4% at closing to 76.9% at KBRA’s current review. The resulting KNCF and KBRA value have declined 29.5% and 31.8%, respectively, from securitization. Given the current performance, the borrower is likely to face refinancing difficulties at the loan’s February 2027 maturity.

The transaction collateral is a non-recourse, first lien mortgage loan secured by the borrower’s fee simple interest in 485 Lexington Avenue, a 32-story, 935,452 sf, Class-A, office building located in the Midtown neighborhood of New York City’s borough of Manhattan. The principal balance for this transaction is $350.0 million as of the January 2026 remittance period. The fixed rate, interest-only loan has a loan term of 10 years with a maturity date in February 2027. The loan sponsor is an affiliate of SL Green Realty Corp. (NYSE: SLG), a REIT.

KBRA analyzed the cash flow for the property utilizing information from the trustee and servicer to determine KNCF. The analysis produced a KNCF of $22.2 million and a KBRA value of $296.4 million ($317 per sf). The resulting in-trust KLTV is 118.1%, compared to 100.3% at last review and 80.5% at securitization. KBRA maintains a KPO of Underperform for the loan due to the decline in financial performance since securitization and the difficulty the borrower will likely face in refinancing the loan at its maturity in February 2027 without improvement in performance or additional equity.
