Step 1 · Market value
Likely range $630,078 – $907,746, from 12 comparable Mendham 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 Mendham assessments sit below market value — republished every October, applied town-wide. A $706,215 home should be assessed near $507,133.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $144,033 below what the ratio math suggests (28.4%).
Step 4 · The tax rate — same for every Mendham home
$1.661 Schools · 66% $0.302 County · 12% $0.563 Town · 22%
Step 5 · The bill

Paying about right
