856 Washington AvenueRecorded sales & closing prices

856 Washington trades as new-development condominium inventory in Prospect Heights, which means it prices on square footage, finish, floor, outdoor space and amenity load — a fundamentally different pricing grammar from the neighborhood's prewar cooperative stock, which prices on rooms. A buyer weighing 856 Washington against a converted Eastern Parkway or Plaza Street co-op is not comparing like with like; the correct comparison runs through total monthly carrying cost, not asking price.

Within the building, the spread is driven by floor, line and outdoor space. The set-back penthouse tier is a separate market from the typical floors, and the difference between an upper-floor apartment with terrace and open southern outlook and a lower-floor apartment behind the neighboring roofline is large. Through the last complete year, the reliable anchor has been the same-line comparable inside this building, with the neighborhood's other post-2015 condominium product as the secondary check.

The competitive set is small and specific: the Pacific Park and Atlantic Yards condominium tier to the northwest, the boutique Prospect Heights condominium conversions, and the newer Park Slope and Crown Heights product. Very little of it sits this close to the Brooklyn Museum, and none of it carries this amenity program at twenty-six units. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.
