Step 1 · Market value
Likely range $1,781,812 – $2,657,473, 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 $2,242,948 home should be assessed near $2,168,931.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $1,049,169 above what the ratio math suggests (48.4%).
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 $0.943 per $100 — below the general rate, usually a deduction on the bill (senior, veteran, disabled).
Step 5 · The bill

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 $11,006/yr at stake. NJ appeals are generally due April 1.
