Single-family homes in the Brookhaven-Comsewogue Union Free School District sold for a median of $640,000 (typically $575,000–$705,000) across 170 recorded sales between Oct 7, 2025 and Oct 2, 2026, up 4.1% on the 12 months before. This home's $899,990 list price sits in the luxury single-family tier for the Brookhaven-Comsewogue Union Free School District.

ZIP 11776 has about 2.7 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 $18,356 a year, this home's property tax runs roughly 53% above the $12,000 typical for Brookhaven-Comsewogue 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.
