Questions about 840 East 17 Street
Who owns 840 East 17 Street?
The city's property file lists 840 REALTY LLC as the owner of record for 840 East 17 Street. 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 840 East 17 Street changed hands recently?
No deed for 840 East 17 Street 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.

Yes. Three marshal-executed evictions at 840 East 17 Street appear in the NYC evictions dataset, the most recent on Jul 21, 2025. 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 840 East 17 Street rent stabilized?
DHCR registrations list 29 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 840 East 17 Street assessed at for property taxes?
The Department of Finance assessed the lot at $1.1M 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 840 East 17 Street?
11230 (Midwood) scores 33.6 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.
