The loan transferred to special servicing on 7/3/2024 due to non-monetary monetary default due to Borrower's non-compliance with cash management provisions after the credit downgrade of the tenant (Walgreens). Special Servicer is working on final revisions of the DACA with Borrower's counsel. Once established and funded, Special Servicer will work to execute a settlement agreement with Borrower, and subsequently begin the Return to Master process.
