Step 1 · Market value
Likely range $630,076 – $849,381, 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 $748,793 home should be assessed near $755,607.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $274,407 below what the ratio math suggests (36.3%).
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 $1.661 per $100 — below the general rate, usually a deduction on the bill (senior, veteran, disabled).
Step 5 · The bill

Keep quiet and enjoy it
This home's assessment ratio sits below the Warren pack — the frozen assessment is treating it kindly. It pays less than a fresh look would charge.
