ZIP 11777 has about 5.8 months of single family inventory — balanced market. Supply and demand are roughly even, so buyers and sellers share leverage with fair, predictable pricing.

At about $21,503 a year, this home's property tax runs roughly 43% above the $15,000 typical for Port Jefferson Union Free 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.
