Step 1 · Market value
Likely range $747,556 – $1,104,731, 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 $833,646 home should be assessed near $598,641.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $48,941 below what the ratio math suggests (8.2%).
Step 4 · The tax rate — same for every Mendham home
$1.661 Schools · 66% $0.302 County · 12% $0.563 Town · 22%
