Assessments are tax year 2026; latest published general rate we have is 2025. Estimate uses that rate until the 2026 rate is loaded.
Estimated tax down $4,332 ($9,152 → $4,820) using 2024→2025 rates (3.906 → 2.057) × assessed net.
Assessment net change: 0.0% ($234,300 → $234,300).

How the ratio works: New Jersey towns often assess below full market value. The average ratio (Director’s / Chapter 123) estimates what percent of true market value the town’s assessments represent. Implied equalized value ≈ assessed net ÷ (ratio ÷ 100). Example: assessed $187,600 at 55.89% ≈ $335,700 equalized. Tax bills still use assessed value × the general tax rate — not the equalized figure.
Change since the 2025 sale of $221,000: implied equalized value $234,300 is $13,300 above that sale. This is not an appraisal.
This class 2 — residential (four families or less) — net assessment sits below the town class-2 average of $362,615.
Published average ratio exceeded 100%; New Jersey treats that as 100% for equalization.

The state’s 10-foot ground scan puts the lowest cell on this lot at 497.8 feet and the highest at 501.6 feet (NAVD88).
These figures are estimates. The zone and any flood elevation come from FEMA’s flood map at a point for this address, and that point can fall in the street. The high and low come from the state’s 10-foot ground scan of the lot outline. A cell can catch a ditch, the street, or the edge of the lot. They are not a survey and not an insurance rating. A licensed surveyor measures the ground and the building. The town floodplain administrator, or a licensed engineer, confirms what the zone means for this lot.
