ZIP 11803 has about 1.5 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 $14,391 a year, this home's property tax runs roughly 15% below the $17,000 typical for Plainview-Old Bethpage Central School District. Nassau assessments run on a multi-year cycle, so the assessed value behind this bill can lag what the home actually sells for today. 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.
