Step 1 · Market value
Likely range $316,227 – $584,555, from 12 comparable Upper 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 Upper assessments sit below market value — republished every October, applied town-wide. A $464,611 home should be assessed near $263,202.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $305,898 above what the ratio math suggests (116.2%).
Step 4 · The tax rate — same for every Upper home
$1.649 Schools · 72% $0.331 County · 14% $0.323 Town · 14%

Looks meaningfully over-assessed
