Useful NYC Real Estate Websites

Resources

Find official sources for taxes, ownership, building records, offering plans and financing research.

Property ownership and recorded documents

Use ACRIS to locate recorded documents by property identifiers or parties. Read the underlying document and confirm that it concerns the correct property. A recorded amount alone may not establish a simple arm’s-length resale. Open the official source

Property taxes and bills

Start with the exact borough, block and lot. For condos, confirm the apartment’s lot. A co-op corporation’s property tax bill is not a shareholder’s separate monthly maintenance bill. Open the official source

Buildings, permits and occupancy

Search both current and older record systems as appropriate. Application descriptions and permit statuses are not proof of completed work or a professional condition assessment. Open the official source

Offering plans and amendments

Use the Attorney General’s database to locate plan information. Ask your attorney to obtain and review the relevant plan and amendments; a search result is not an endorsement or legal opinion. Open the official source

Zoning and land use

Use ZoLa to screen the lot’s zoning and mapped context. A map does not establish approval for a proposed renovation or development; consult qualified professionals. Open the official source

FHA condominium project search

Check project name, address, approval status and dates. Ask the lender to confirm current project and unit eligibility; a search match is not a loan commitment. Open the official source

Compare mortgage disclosures

Use the CFPB explainer to compare Loan Estimates on the same basis and identify costs outside principal and interest. Confirm rate-lock details and current fees with the lender. Open the official source

Use sources together

Record the address, identifiers and date checked. Where records disagree, retain the discrepancy and ask the relevant professional to reconcile it. A missing online result does not establish that a document or issue does not exist.
