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 2016 sale of $465,000: implied equalized value $1,051,477 is $586,477 above that sale. This is not an appraisal.
This class 2 — residential (four families or less) — net assessment sits above the town class-2 average of $293,682.
