ZIP 11779 has about 2 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 $20,147 a year, this home's property tax runs roughly 68% above the $12,000 typical for Connetquot 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.
