ZIP 11793 has about 2.6 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 $17,039 a year, this home's property tax runs roughly 14% above the $15,000 typical for Wantagh 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.
