Single-family homes in the Westhampton Beach Union Free School District sold for a median of $2,200,000 (typically $1,375,000–$3,000,000) across 100 recorded sales between Oct 7, 2025 and Sep 29, 2026, up 16.7% on the 12 months before.

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.
