Questions about 3950 Blackstone Avenue
Who owns 3950 Blackstone Avenue?

Has 3950 Blackstone Avenue changed hands recently?

Have there been evictions at 3950 Blackstone Avenue?
Yes. Six marshal-executed evictions at 3950 Blackstone Avenue appear in the NYC evictions dataset, the most recent on Jul 17, 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 3950 Blackstone Avenue rent stabilized?

Yes. New York State granted 1 rent overcharge case at this address, meaning DHCR found a tenant had been charged above the legal rent.

The figures come from a freedom of information response covering cases closed between January 2021 and April 2026.
What is 3950 Blackstone Avenue assessed at for property taxes?
The Department of Finance assessed the lot at $6.8M 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 3950 Blackstone Avenue?
