BSTN Commercial Mortgage Trust 2026-L5 secures final Morningstar DBRS ratings for Boston office CMBS
Why this matters
Capital markets activity continues to be defined by the rotation from bank balance sheets to non-bank lenders. Private credit funds have raised record dry powder; banks have tightened CRE underwriting standards for the sixth consecutive quarter. The result is a market where well-sponsored deals clear, and marginal credit pays a meaningful spread to do so. Boston life sciences absorption has moderated from its 2021-2022 pace, and the market is working through a meaningful Cambridge sublease overhang. Multifamily and trophy office remain durable. For LPs, the allocation conversation has shifted decisively toward real estate debt, with equity allocations being deployed more selectively into operator-led platforms.
