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.

ZIP 11751 has about 1.6 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 $16,322 a year, this home's property tax runs roughly 17% 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.
