Single-family homes in the Islip Union Free School District sold for a median of $715,000 (typically $630,000–$820,000) across 114 recorded sales between Oct 22, 2025 and Sep 29, 2026, up 5.9% on the 12 months before. This home's $699,000 list price sits in the mid-market single-family tier for the Islip Union Free School District.
ZIP 11751 has about 2.1 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 $15,907 a year, this home's property tax runs roughly 14% above the $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.
