Taxes and assessed value
The city's Department of Finance assessed this lot at $43.8M for the 2026 tax year. That works out to $243K per residential unit. Assessed value is what the city taxes, not what the building would sell for, and the two routinely differ by a wide margin. The bill itself turns on the tax class rate and on any exemptions or abatements attached to the lot, neither of which is published here.
What the eviction record shows
No executed eviction is on record at 400 East 84Th Street in the citywide marshal file, which runs from April 2024.
Rent stabilization at this address
No DHCR rent-stabilization registration is on file for 400 East 84Th Street in the years PulseCities holds.

Has 400 East 84Th Street changed hands recently?

Have there been evictions at 400 East 84Th Street?
No executed eviction at 400 East 84Th Street 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 400 East 84Th Street rent stabilized?
No DHCR registration for 400 East 84Th Street appears in the years PulseCities holds. That is a gap in the registration record rather than an answer about any apartment, and the free rent history from NYS Homes and Community Renewal is what settles it.
What is 400 East 84Th Street assessed at for property taxes?
The Department of Finance assessed the lot at $43.8M 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 400 East 84Th Street?
10028 (Upper East Side) scores 25.2 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.
Sourced from NYC public records: ACRIS deeds, DOB permits, the NYC evictions dataset, and 311. Records reflect what agencies have published and can lag events.
