Step 1 · Market value
Likely range $295,510 – $423,049, from 12 comparable Berkeley 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 Berkeley assessments sit below market value — republished every October, applied town-wide. A $373,898 home should be assessed near $197,979.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $22,679 below what the ratio math suggests (11.5%).
Step 4 · The tax rate — same for every Berkeley home
$1.213 Schools · 47% $0.582 County · 22% $0.795 Town · 31%
Step 5 · The bill
This home vs. every recent Berkeley sale · assessed ÷ market

Paying about right
This home's ratio lands inside Berkeley's normal band. The drift hasn't singled it out — no case for a tax appeal.
