Single-family homes in the Northport-East Northport Union Free School District sold for a median of $850,000 (typically $720,000–$1,200,000) across 289 recorded sales between Oct 17, 2025 and Oct 2, 2026, up 4.3% on the 12 months before. This home's $499,990 list price sits in the entry single-family tier for the Northport-East Northport Union Free School District.
ZIP 11731 has about 1.8 months of single family inventory — hot seller's market. Severe inventory shortage — homes sell fast and often draw multiple offers over asking, giving sellers maximum leverage.
At about $5,088 a year, this home's property tax runs roughly 61% below 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.
