Step 1 · Market value
Likely range $752,289 – $1,136,400, from 12 comparable Warren 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 Warren assessments sit below market value — republished every October, applied town-wide. A $900,251 home should be assessed near $908,443.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $70,343 below what the ratio math suggests (7.7%).
Step 4 · The tax rate — same for every Warren home
$1.140 Schools · 65% $0.333 County · 19% $0.279 Town · 16%
This home's own bill implies $1.645 per $100 — below the general rate, usually a deduction on the bill (senior, veteran, disabled).
Step 5 · The bill
This home vs. every recent Warren sale · assessed ÷ market

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