Single-family homes in the Amityville Union Free School District sold for a median of $689,000 (typically $625,000–$755,000) across 45 recorded sales between Oct 28, 2025 and Sep 22, 2026, up 7.6% on the 12 months before. This home's $699,000 list price sits in the mid-market single-family tier for the Amityville Union Free School District.

ZIP 11758 has about 2.3 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 $11,985 a year, this home's property tax is in line with the roughly $12,000 typical for Amityville Union Free School District. Nassau assessments run on a multi-year cycle, so the assessed value behind this bill can lag what the home actually sells for today. A sale does not automatically reset it, and 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.
