LONG ISLAND HOME BUYING
Buying a home in Nassau County.
For a Nassau County home purchase, assemble the property record and the ownership-cost details before comparing offers. Taxes, alterations and association obligations can affect the decision as much as the advertised room count. Use the county's records as a starting point, then confirm the details with the offices and professionals responsible.
Read the Land Records Viewer carefully
Nassau's Land Records Viewer provides assessment information, district details, tax maps, property photographs, past taxes, exemptions and comparable-sales resources. Match the section, block and lot to the property being sold. Keep the record date and tax year with your notes. A historical exemption or past tax amount is not a promise of the bill a new owner will receive.

Trace additions to the appropriate approvals
Ask which town, city or village office holds the building records for this address. Request documentation for material additions, converted spaces, pools and other improvements important to your purchase. Have the appropriate professional compare the actual use with the available approvals. Budget separately for planned work; the asking price does not establish that a renovation or additional occupancy is permitted.

Separate recorded rights from physical features
Use the county's land-record entry point to identify documents for counsel's review. A driveway, fence, parking area or waterfront feature can require questions about title, survey and access rights. Ask the insurer about the specific address and coverage needed. For an association property, include monthly charges and assessments in the comparison rather than looking only at the mortgage payment.

Bring the open questions into your offer plan.
Use the documents to decide what still needs investigation, who will obtain it and which dates matter. Review the proposed price, financing, inspections and any requested seller payment of brokerage fees together. A lower fee does not remove the need for a clear agreement and property-specific review.
- Section block lot and district information
- Actual tax bills and exemption questions

- Title survey and access documents
- Insurance and association costs
A question before your move.
Will I receive the seller's property-tax exemptions?
Do not assume they transfer. Identify the exemptions reflected in the records and ask the assessor which requirements and applications would apply to you. Use a budget that accounts for uncertainty until confirmed.
Compare the places you are considering.
