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 2012 sale of $2,490,000: implied equalized value $3,628,200 is $1,138,200 above that sale. This is not an appraisal.

Published average ratio exceeded 100%; New Jersey treats that as 100% for equalization.
