Questions about 621 Flatbush Avenue
Who owns 621 Flatbush Avenue?
The city's property file lists FENIMORE PLAZA LLC as the owner of record for 621 Flatbush Avenue. No deed for this lot appears in the ACRIS records PulseCities holds, so that name comes from the tax roll rather than from a recorded transfer.
Has 621 Flatbush Avenue changed hands recently?
No deed for 621 Flatbush Avenue appears in the ACRIS records PulseCities holds. That means no transfer has been published for this lot in the current window, not that the building has never been sold.
Have there been evictions at 621 Flatbush Avenue?
No executed eviction at 621 Flatbush Avenue appears in the NYC evictions dataset, which PulseCities holds from April 2024 forward. Executed evictions are the end of the process, so a building with none may still have active housing court cases.
Is 621 Flatbush Avenue rent stabilized?
DHCR registrations list 9 stabilized units at this building in 2023. Registration is building-level, so it does not settle whether one apartment is stabilized. The free rent history from NYS Homes and Community Renewal does.
What is 621 Flatbush Avenue assessed at for property taxes?
The Department of Finance assessed the lot at $532K for the 2026 tax year. That is the figure the city taxes rather than a sale price, and the bill depends on the tax class rate and on any exemptions on the lot.
What is the displacement risk around 621 Flatbush Avenue?
11225 (Crown Heights) scores 43.4 out of 100 on the PulseCities displacement index. The score reads five ZIP-level signals: LLC acquisition rate, permit intensity, 311 complaint volume, executed evictions, and serious HPD violations. It describes the area around the building, not the building itself.
