Questions about 784 Knickerbocker Avenue
Who owns 784 Knickerbocker Avenue?
The city's property file lists JC REAL ESTATE DEVELOPMENT L.P. as the owner of record for 784 Knickerbocker 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 784 Knickerbocker Avenue changed hands recently?
No deed for 784 Knickerbocker 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 784 Knickerbocker Avenue?
Yes. One marshal-executed eviction at 784 Knickerbocker Avenue appears in the NYC evictions dataset, the most recent on May 28, 2024. The dataset covers executed evictions only, so it undercounts housing court activity: cases that settle or end in a move-out never reach a marshal.
Is 784 Knickerbocker Avenue rent stabilized?
DHCR registrations list 3 stabilized units at this building in 2019. 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 784 Knickerbocker Avenue assessed at for property taxes?
The Department of Finance assessed the lot at $466K 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 784 Knickerbocker Avenue?
11207 (East New York) scores 45.9 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.
