cmbs.news's own rule-based labels on the filed fields (definitions), not a credit rating, a prediction or a view of the borrower.
What the filing shows
- Occupancy has fallen from 89% when the loan was securitized to 80%.
- Net operating income is 16% below the underwritten figure ($1.5M a year against $1.8M).
- Debt service coverage moved from 2.05x at securitization to 1.72x on the latest statements.
- The filing gives Jun 2030 as the lease end date for the largest tenant (University of Chicago), before the loan matures. Lenders look hard at that rollover.
