Jack Guttman has added to his Long Island City holdings with the acquisition of a discounted life sciences building.

Pearl Realty Management bought the Hatch Life Sciences Building at 43-10 23rd St. in Queens from Longfellow Real Estate Partners for $86.9M, according to property records.
That is roughly $6M less than Boston-based Longfellow paid when it partnered with Sculptor Real Estate to buy the 215K SF building in 2021 from Columbia Property Trust for $92.5M, Commercial Observer reported.
The partners then redeveloped the property, a former parachute manufacturing factory, into life sciences space from August 2022 to September 2023, Crain's New York Business reported.
It is unclear how much Longfellow ended up pouring into its remodeling, but it had planned to invest $120M to convert the former parachute manufacturing plant into a mix of labs and offices, CO reported.
The deal is a possible deed-in-lieu-of-foreclosure transaction, because Pearl Realty had purchased the debt on the building from its former lender, Affinius Capital, PincusCo reported.
The loss comes as New York City’s life sciences real estate struggles. The city had the highest availability rate of any U.S. life sciences market at the end of Q1, at 37%, according to JLL.
