Single-family homes in the Central Islip Union Free School District sold for a median of $610,000 (typically $545,000–$665,000) across 171 recorded sales between Oct 6, 2025 and Oct 2, 2026, up 5.2% on the 12 months before. This home's $514,999 list price sits in the entry single-family tier for the Central Islip Union Free School District.

ZIP 11722 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 $8,400 a year, this home's property tax runs roughly 16% below the $10,000 typical for Central 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.
