Has 601 Prospect Avenue changed hands recently?

Have there been evictions at 601 Prospect Avenue?
No executed eviction at 601 Prospect Avenue 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 601 Prospect Avenue rent stabilized?

What is 601 Prospect Avenue assessed at for property taxes?
The Department of Finance assessed the lot at $168K 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.
