Step 1 · Market value
Likely range $723,375 – $1,986,224, from 12 comparable Summit 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 Summit assessments sit below market value — republished every October, applied town-wide. A $1,461,043 home should be assessed near $450,147.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $87,547 below what the ratio math suggests (19.4%).
Step 4 · The tax rate — same for every Summit home
$2.335 Schools · 52% $1.092 County · 24% $1.043 Town · 23%
This home's own bill implies $4.402 per $100 — below the general rate, usually a deduction on the bill (senior, veteran, disabled).
Summit also levies a Special Improvement District charge inside its district boundaries — the county roll doesn't say which homes are in it, but a bill's "IMPROVEMENT DISTRICT" line does. District homes pay $4.654 per $100 all-in (+$0.184).

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