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 $690,000: implied equalized value $579,600 is $110,400 below 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 class 2 — residential (four families or less) — net assessment sits below the town class-2 average of $991,079.

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 85.11% (often still reflecting the prior assessment base).
