Step 1 · Market value
Likely range $1,559,367 – $2,292,963, 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 $1,893,544 home should be assessed near $1,920,243.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $269,643 below what the ratio math suggests (14.0%).
Step 4 · The tax rate — same for every Demarest home
$1.149 Schools · 64% $0.219 County · 12% $0.438 Town · 24%
