Single-family homes in the Northport-East Northport Union Free School District sold for a median of $845,000 (typically $720,000–$1,185,000) across 301 recorded sales between Oct 6, 2025 and Oct 2, 2026, up 3.7% on the 12 months before.

ZIP 11768 has about 2.9 months of single family inventory — seller's market. Demand is outpacing supply, so homes sell quickly with firm pricing and limited room to negotiate.
At about $28,561 a year, this home's property tax runs roughly 120% above the $13,000 typical for Northport-East Northport Union Free School District. Suffolk bills combine town, school and special-district levies, so two homes at the same price in neighboring districts can carry materially different taxes. Exemptions such as STAR, Senior or Veteran move the number as well — a new owner's bill is often not the same as the seller's.
