Start by visiting the county’s Real Estate Records page and selecting your search method: address, APN, or owner name. Each result provides a comprehensive profile of the property, including its current assessed value, market value estimate, tax class (residential, commercial, agricultural), and any applicable exemptions.

Land Records, Deeds, and Mortgages in Nassau County
The Land Records division of the Nassau County Clerk’s Office manages all official documents related to property transfers, including deeds, mortgages, liens, and easements. Since 2018, the office has supported electronic filing through the New York Unified Court System, enabling attorneys, title companies, and lenders to submit documents digitally. This e-filing system reduces processing time from days to hours and improves accuracy. Standard recording fees are $45 for a deed, $75 for a mortgage, and $25 for corrected instruments. The division also offers notarization services and maintains a Property Fraud Alert program that notifies owners if suspicious changes appear on their records. In-person help is available at the Hempstead office during business hours.
Property Assessment Data and Tax Information
Nassau County provides transparent access to property assessment rolls through its Land Records Viewer. This interactive tool shows each parcel’s taxable value, class code, exemption amount, and district information. Users can view high-resolution property photos taken during field surveys, detailed tax maps with utility overlays, and a history of tax rates from 2000 to present. The system also includes comparable sales within a one-mile radius, helping owners benchmark their assessments against recent market activity. Property owners receive annual assessment notices in July and can challenge inaccurate values using the online Assessment Challenge Form. The Tax Department publishes a detailed calendar outlining deadlines for filing objections, attending hearings, and receiving final decisions.
Fraud Protection and Public Safety Tools
To combat property fraud, Nassau County offers a free Property Fraud Alert service. Homeowners can sign up to receive immediate notifications if someone attempts to file a deed, mortgage, or lien using their name or property details. This early warning system helps prevent identity theft and unauthorized transactions. The alert is voluntary and requires registration through the Clerk’s Office website. Staff members are trained to assist with fraud concerns and can guide users through next steps if suspicious activity is detected. Additionally, the county prohibits deputy clerks from giving legal advice but provides procedural guidance in line with state law.
Historical Records and Long-Term Research
Nassau County maintains an extensive archive of property transactions dating back to 1895. Researchers, historians, and legal professionals can access indexed records of deeds, mortgages, and subdivision plats through the official portal or by visiting the Clerk’s Office in person. Each document is linked to its official parcel number (APN) and can be filtered by date, document type, or parties involved. The GIS mapping system enhances research by showing how parcels have changed over time, including boundary adjustments, zoning updates, and development patterns. Certified copies of historical documents can be requested via mail for legal or archival purposes.

You can identify property owners by searching the Nassau County Real Estate Records portal using the street address or parcel number. The system displays current owner names, mailing addresses, and legal descriptions. Ownership information is updated after each recorded deed transfer.

Submit the completed form along with supporting evidence—such as recent appraisals or photos of damage—by the published deadline. The Board of Assessment Review holds hearings in January, and decisions are mailed by March. If unsatisfied, you may appeal to the New York State Division of Taxation.
