Single-family homes in the Three Village Central School District sold for a median of $835,000 (typically $730,000–$990,000) across 338 recorded sales between Oct 4, 2025 and Oct 1, 2026, up 9% on the 12 months before. This home's $729,000 list price sits in the entry single-family tier for the Three Village Central School District.

ZIP 11790 has about 2.1 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 $15,396 a year, this home's property tax is in line with the roughly $17,000 typical for Three Village Central 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.
