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 2019 sale of $11,000,000: implied equalized value $18,062,100 is $7,062,100 above that sale. This is not an appraisal. This is a reassessment year, so the ratio is treated as about 100% and the gap is today’s assessment minus the sale price.

This town revalued/reassessed for tax year 2026. New assessments are set near true market value, so we treat the ratio as ~100% for this year. Published Chapter 123 average ratio for appeals/statistics is still 87.00% (often still reflecting the prior assessment base).

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.
