Single-family homes in the Islip Union Free School District sold for a median of $716,000 (typically $630,000–$820,000) across 117 recorded sales between Oct 9, 2025 and Sep 29, 2026, up 6.1% on the 12 months before. This home's $680,000 list price sits in the mid-market single-family tier for the Islip Union Free School District.

ZIP 11751 has about 2 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 $13,395 a year, this home's property tax is in line with the roughly $14,000 typical for 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.
