Step 1 · Market value
Likely range $3,753,211 – $5,083,829, 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 $4,186,244 home should be assessed near $4,048,098.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $770,102 above what the ratio math suggests (19.0%).
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 $0.925 per $100 — below the general rate, usually a deduction on the bill (senior, veteran, disabled).
Step 5 · The bill
This home vs. every recent Rumson sale · assessed ÷ market

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