Single-family homes in the William Floyd Union Free School District sold for a median of $510,000 (typically $430,000–$580,000) across 494 recorded sales between Oct 6, 2025 and Oct 2, 2026, up 5.2% on the 12 months before. This home's $799,000 list price sits in the luxury single-family tier for the William Floyd Union Free School District.

ZIP 11950 has about 2 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 $812 a year, this home's property tax runs roughly 90% below the $8,000 typical for William Floyd 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.
