Understanding Long Island Closing Costs

Buying a home on Long Island involves several transfer taxes and closing costs beyond your down payment. Here's what our calculator captures:

NY Mansion Tax (1% – 3.9%)

Applies to residential sales of $1M or more. Paid by the buyer at closing. Rates step up progressively — 1% at $1M, up to 3.9% at $25M+. Common on Nassau North Shore and waterfront Suffolk purchases. Read our full mansion tax guide.

Mortgage Recording Tax

Paid by the borrower when a new mortgage is recorded. Roughly 1.05% under $500K loans, 1.30% above. If you're refinancing, ask about CEMA — it can save you thousands.

Title Insurance

Two policies typically: an owner's policy (protects you) and a lender's policy (protects your mortgage company). Combined cost varies with purchase price and loan amount.

Peconic Bay Community Preservation Fund (East End only)

If you're buying in Riverhead, Southampton, East Hampton, Shelter Island, or Southold, a 2% transfer tax applies to amounts above a town-specific threshold. Paid by the buyer.

Attorney Fees, Survey, and Inspections

Real estate attorney fees on Long Island typically range $1,500–$3,000. Add a survey ($750–$1,200) if required, plus inspection costs (septic/well for Suffolk properties, termite, oil tank, etc.).
