Step 1 · Market value
Likely range $4,060,141 – $6,246,383, from 12 comparable Rumson 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 Rumson assessments sit below market value — republished every October, applied town-wide. A $4,912,559 home should be assessed near $4,750,445.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $2,743,855 above what the ratio math suggests (57.8%).
Step 4 · The tax rate — same for every Rumson home
$0.594 Schools · 57% $0.210 County · 20% $0.245 Town · 23%
This home's own bill implies $0.917 per $100 — below the general rate, usually a deduction on the bill (senior, veteran, disabled).

Looks meaningfully over-assessed
Even at the generous end of the range, this home's ratio clears the Chapter 123 appeal line (100.00%) — roughly $28,783/yr at stake. NJ appeals are generally due April 1.
