This home's $749,000 list price sits in the upper single-family tier for the Amityville Union Free School District.

ZIP 11758 has about 2.4 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 $15,163 a year, this home's property tax runs roughly 26% above the $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.
