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.
The stored sale is not used for a change-since-sale figure. SR1A 30 — Several parcels sold as a package, with the price split arbitrarily marks it non-usable, or the price is a nominal amount.
