Questions about 9 Thayer Street
Who owns 9 Thayer Street?
The city's property file lists GVS PROPERTIES IV, LLC as the owner of record for 9 Thayer 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 9 Thayer Street changed hands recently?
No deed for 9 Thayer 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.
Have there been evictions at 9 Thayer Street?
Yes. Six marshal-executed evictions at 9 Thayer Street appear in the NYC evictions dataset, the most recent on Aug 3, 2026. 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 9 Thayer Street rent stabilized?
DHCR registrations list 78 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 9 Thayer Street assessed at for property taxes?
The Department of Finance assessed the lot at $2M 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 9 Thayer Street?
10040 (Inwood) scores 40.4 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.
