At about $12,393 a year, this home's property tax runs roughly 11% below the $14,000 typical for Massapequa Union Free 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.
