The Fair Share Report

320 Summit Rd

Mountainside, NJ 07092

The town corrects for market drift once a year — but only on average. This report measures whether this house drifted with the herd or away from it.

Step 1 · Market value

≈ $902,733

Likely range $789,869 – $1,038,957, from 12 comparable Mountainside sales in the past 18 months (home size estimated from assessor data — range widened).

Step 2 · The Director's Ratio

71.29%

The state's official measure of how far Mountainside assessments sit below market value — republished every October, applied town-wide. A $902,733 home should be assessed near $643,558.

Step 3 · Assessed value

$620,100

Set at the last town-wide revaluation and mostly frozen since. That's $23,458 below what the ratio math suggests (3.6%).

Step 4 · The tax rate — same for every Mountainside home

$2.099 per $100 assessed

$1.023 Schools · 49% $0.482 County · 23% $0.594 Town · 28%
