ZIP 11729 has about 2.7 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 $15,452 a year, this home's property tax runs roughly 19% below the $19,000 typical for Half Hollow Hills Central School District. Suffolk bills combine town, school and special-district levies, so two homes at the same price in neighboring districts can carry materially different taxes. 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.
