Step 1 · Market value
Likely range $824,585 – $1,357,884, from 12 comparable Madison 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 Madison assessments sit below market value — republished every October, applied town-wide. A $1,214,899 home should be assessed near $731,612.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $255,312 below what the ratio math suggests (34.9%).
Step 4 · The tax rate — same for every Madison home
$1.423 Schools · 63% $0.350 County · 16% $0.481 Town · 21%
Step 5 · The bill
This home vs. every recent Madison sale · assessed ÷ market

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