Single-family homes in the Brentwood Union Free School District sold for a median of $640,000 (typically $580,000–$685,000) across 273 recorded sales between Oct 17, 2025 and Oct 1, 2026, up 5.8% on the 12 months before. This home's $719,000 list price sits in the upper single-family tier for the Brentwood Union Free School District.

ZIP 11717 has about 3.4 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 $7,840 a year, this home's property tax runs roughly 13% below the $9,000 typical for Brentwood 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.
