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 $150,000: implied equalized value $103,018 is $46,982 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 $109,810.

Flood zone for 959 SO 2ND ST

FEMA’s flood map places the mapped point for 959 SO 2ND ST in zone X.

The state’s 10-foot ground scan puts the lowest cell on this lot at 83.5 feet and the highest at 85 feet (NAVD88).

These figures are estimates. The zone and any flood elevation come from FEMA’s flood map at a point for this address, and that point can fall in the street. The high and low come from the state’s 10-foot ground scan of the lot outline. A cell can catch a ditch, the street, or the edge of the lot. They are not a survey and not an insurance rating. A licensed surveyor measures the ground and the building. The town floodplain administrator, or a licensed engineer, confirms what the zone means for this lot. No zone at this point, or zone X, does not mean the lot will not flood.
