Lab Vacancy Hits 28.7% as Lender Takes Back South End Life Sciences Property
BioMed Realty has handed over ownership of its two-building lab and office complex at 1000 Washington St. and 321 Harrison Ave. in Boston's South End to its lenders, KKR Real Estate Finance Trust and AllianceBernstein, according to Bisnow. BioMed borrowed $322 million against the property in 2021 to convert it from office to lab space during the pandemic-era life sciences boom. That boom reversed, and Greater Boston lab vacancy now sits at 28.7% as of the second quarter, per CBRE.
An ownership transfer like this signals a valuation gap between what a property was underwritten to be worth and what today's market supports. Boston Appraisal Services specializes in exactly these complex, transitional properties, the kind automated valuation models miss entirely. Getting the value right on an asset like this takes more than a desktop estimate.
