Step 1 · Market value
Likely range $2,385,614 – $3,018,365, 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 $2,655,556 home should be assessed near $2,567,923.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $716,423 below what the ratio math suggests (27.9%).
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 $0.921 per $100 — below the general rate, usually a deduction on the bill (senior, veteran, disabled).
Step 5 · The bill

Keep quiet and enjoy it
This home's assessment ratio sits below the Rumson pack — the frozen assessment is treating it kindly. It pays less than a fresh look would charge.
