858 Atlantic Avenue trades for $3.9M

Overview

858 Atlantic Development LLC sold 858 Atlantic Avenue in Prospect Heights to Atlantic Equties NY LLC, as the buyer's name is spelled on the deed, for $3.9 million, according to a deed dated Aug. 24, 2026 and recorded on Sept. 1, 2026. PincusCo reported the same $3.9 million price.

The buyer financed the purchase with two mortgages from S3 SB Real Estate Credit A Trust, recorded the same day: $11.1 million and $2.9 million, or $14 million in all. A related assignment of leases and rents was recorded for $2.9 million.

The interior lot, Brooklyn Block 1122, Lot 11, sits on Atlantic Avenue between Vanderbilt and Underhill avenues and holds a one-story garage built in 1930, according to city records. In March 2026, before the sale, permits were filed for a 15-story, 155-foot mixed-use building on the site with 36 apartments and 23,884 square feet, according to New York YIMBY, which named Barry Wagschal of Wagstone Capital as the owner behind the applications. The records do not show whether the new owner will pursue that plan.
