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.

ZIP 11951 has about 5.3 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 $5,377 a year, this home's property tax runs roughly 33% below the $8,000 typical for William Floyd Union Free School District.

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.
