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 $915,000: implied equalized value $785,228 is $129,772 below 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 $1,004,213.
