220 HARTSHORN DRIVE

Assessment

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 2013 sale of $7,500,000: implied equalized value $13,178,806 is $5,678,806 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 $1,315,956.

Flood zone for 220 HARTSHORN DRIVE

The flood map could not be checked for 220 HARTSHORN DRIVE, because the address did not place a point on the map. Assessment and tax figures on this page are from our own records.

The state’s 10-foot ground scan puts the lowest cell on this lot at 345.6 feet and the highest at 401.6 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.

Assessed value & ratio history

Tax year history

Assessed net is from that year’s MOD-IV file. Est. tax = assessed × that year’s general rate when we have the rate sheet. Billed tax is the MOD-IV tax field when present (often empty for the newest file year).

Of the estimated increase of $3,414, the school portion moved $1,200 up, the county portion $369 down, and the municipal portion $2,584 up. Those are pieces of the dollar change. They are not a change in each share of the rate.

Property details

The class, building class, SR1A, and special-tax words are the state’s names for those codes. The zoning code is the town’s. A code that is not on the state list keeps the code and says so.
