Single-family homes in the West Islip Union Free School District sold for a median of $775,000 (typically $700,000–$920,000) across 187 recorded sales between Oct 8, 2025 and Oct 2, 2026, up 2.5% on the 12 months before. This home's $1,168,000 list price sits in the upper single-family tier for the West Islip Union Free School District.

ZIP 11795 has about 2.4 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 $12,434 a year, this home's property tax runs roughly 11% below the $14,000 typical for West 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.
