Single-family homes in the William Floyd Union Free School District sold for a median of $510,000 (typically $430,000–$575,000) across 479 recorded sales between Oct 17, 2025 and Oct 2, 2026, up 5.2% on the 12 months before. This home's $500,000 list price sits in the mid-market single-family tier for the William Floyd Union Free School District.

ZIP 11951 has about 5.6 months of single family inventory — balanced market. Supply and demand are roughly even, so buyers and sellers share leverage with fair, predictable pricing.

At about $13,897 a year, this home's property tax runs roughly 74% above 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.
