Informational use only

BlockBook republishes public records from City of New York open data and performs standard mortgage arithmetic on them. Nothing on this site is financial, legal, tax, or investment advice, and no figure shown here should be the sole basis for a purchase, sale, loan, or legal decision.

Data accuracy

Public records can be incomplete, delayed, or wrong, and this site may display them with errors of its own. In particular:

• Tax figures are computed from the city's current assessment roll and official class rates. They can differ from the owner's actual bill, which may include abatements, exemptions, or recent changes.
• Condominium and co-op units are assessed individually; a building-level lookup may show the base lot rather than any specific unit.
• Assessed "market values" are the Department of Finance's estimates and are usually well below what a property would sell for.
• Rent-regulation status is an indicator derived from public datasets, not a legal determination.

Verify anything important directly with the NYC Department of Finance, ZoLa, or a licensed professional.
