KBRA Affirms All Ratings for 280 Park Avenue 2017-280P

KBRA affirms all outstanding ratings for 280 Park Avenue 2017-280P, a $1.1 billion CMBS SASB transaction. The affirmations follow a surveillance review of the transaction, which has exhibited a decline in KNCF and KBRA value since issuance. However, the magnitude of the change does not warrant rating adjustments at this time. The affirmations reflect the high quality of the collateral asset and experience of the sponsor. KBRA also considered the loan modification and maturity extension, and the property’s low near-term lease rollover exposure.

The transaction collateral is a non-recourse, first-lien mortgage loan secured by the borrower’s fee simple interest in a 1.3 million-sf Class-A office property at 280 Park Avenue between East 48th and East 49th Streets in the Plaza District of New York City’s Manhattan borough. The loan’s sponsor is owned by affiliates of SL Green Realty Corp. (50.0% ownership) and Vornado Realty Trust (50.0%). The floating-rate loan has an outstanding principal balance of $1.075 billion ($853 per sf) as of the August 2026 remittance period.

The loan’s original fully extended maturity date was September 9, 2024, but the loan was modified in April 2024, extending maturity to September 2026. The modification provides for two additional extension options, subject to certain conditions including an equity contribution for each extension. The new fully extended maturity is in September 2028. Per the servicer, the borrower has provided notice to exercise its extension through September 2027.

The review utilized information from the trustee and servicer to analyze the loan collateral. The analysis produced a KNCF of $63.6 million and a KBRA value of $894.7 million ($710 per sf). The resulting in-trust KLTV is 120.1%, compared to 117.2% at last review and 103.0% at securitization. KBRA maintains the loan’s K-LOC designation and its KPO of Underperform.
