Single-family homes in the East Islip Union Free School District sold for a median of $735,000 (typically $645,000–$870,000) across 167 recorded sales between Oct 17, 2025 and Oct 1, 2026, up 8.1% on the 12 months before. This home's $749,999 list price sits in the mid-market single-family tier for the East Islip Union Free School District.

ZIP 11730 has about 2.8 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 $10,953 a year, this home's property tax is in line with the roughly $12,000 typical for East Islip 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.
