Single-family homes in the Southampton Union Free School District sold for a median of $3,150,000 (typically $1,695,000–$5,140,000) across 95 recorded sales between Oct 9, 2025 and Sep 29, 2026, up 27.4% on the 12 months before.

At about $8,682 a year, this home's property tax runs roughly 45% above the $6,000 typical for Southampton 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.
