Step 1 · Market value
Likely range $1,059,799 – $1,473,980, from 12 comparable Mountainside sales in the past 18 months (home size estimated from assessor data — range widened).
Step 2 · The Director's Ratio
The state's official measure of how far Mountainside assessments sit below market value — republished every October, applied town-wide. A $1,348,694 home should be assessed near $961,484.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $21,484 below what the ratio math suggests (2.2%).
Step 4 · The tax rate — same for every Mountainside home
$1.023 Schools · 49% $0.482 County · 23% $0.594 Town · 28%
Step 5 · The bill
This home vs. every recent Mountainside sale · assessed ÷ market

Paying about right
This home's ratio lands inside Mountainside's normal band. The drift hasn't singled it out — no case for a tax appeal.
