Bills here run lower partly because homes are worth less. That alone doesn’t mean anyone is over-assessed: what counts is how your home compares with similar homes in Uniondale.

How often Uniondale grieves
Across Nassau, most homes that file win a reduction. The dark line on each bar is Nassau as a whole.
One-to-three family homes. Filings are Nassau’s list of applications for the 2028 roll; a reduction is a final assessment below what the County’s 6% cap would have set. Winners’ cuts averaged 7% on the 2027 roll. Compare every district or read how a grievance works.

How values have moved
Imported rolls cover only one year so far, so this uses the year-by-year values on the County’s own record pages for the 42 homes in Uniondale whose records we have retrieved. That is a sample, not every home, so its medians differ from the figures above.

Reading these figures
A median describes Uniondale, not your home, which may sit well above or below it for good reasons. The tentative roll can still change before it becomes final. Recorded payments are not a tax bill: exemptions and special districts vary by home. This page summarizes published records and is not an appraisal; verify any figure that matters in the Nassau County Land Records Viewer, and see how these pages are built.
