Step 1 · Market value
Likely range $1,109,218 – $1,399,697, from 12 comparable Demarest 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 Demarest assessments sit below market value — republished every October, applied town-wide. A $1,264,537 home should be assessed near $1,282,367.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $65,733 above what the ratio math suggests (5.1%).
Step 4 · The tax rate — same for every Demarest home
$1.149 Schools · 64% $0.219 County · 12% $0.438 Town · 24%
