ZIP 11572 has about 3.5 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 $12,325 a year, this home's property tax runs roughly 12% below the $14,000 typical for Oceanside 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.
