Single-family homes in the Plainview-Old Bethpage Central School District sold for a median of $989,000 (typically $870,000–$1,250,000) across 263 recorded sales between Nov 7, 2025 and Nov 3, 2026, up 4.1% on the 12 months before. This home's $1,988,000 list price sits in the luxury single-family tier for the Plainview-Old Bethpage Central School District.

ZIP 11803 has about 1.6 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 $15,782 a year, this home's property tax is in line with the roughly $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.
