Single-family homes in the Brentwood Union Free School District sold for a median of $636,000 (typically $575,000–$680,000) across 285 recorded sales between Oct 6, 2025 and Oct 1, 2026, up 5.1% on the 12 months before.

ZIP 11717 has about 3.5 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 $13,026 a year, this home's property tax runs roughly 45% above 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.
