ZIP 11790 has about 1.4 months of single family inventory — hot seller's market. Severe inventory shortage — homes sell fast and often draw multiple offers over asking, giving sellers maximum leverage.

At about $17,292 a year, this home's property tax is in line with the roughly $16,000 typical for Three Village 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.
