ZIP 11566 has about 2.5 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 $24,428 a year, this home's property tax runs roughly 44% above the $17,000 typical for Merrick Union Free School District.

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.
