Step 1 · Market value
Likely range $517,531 – $648,087, from 12 comparable Sparta 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 Sparta assessments sit below market value — republished every October, applied town-wide. A $595,804 home should be assessed near $356,410.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $90,610 below what the ratio math suggests (25.4%).
Step 4 · The tax rate — same for every Sparta home
$2.362 Schools · 64% $0.624 County · 17% $0.681 Town · 19%
Step 5 · The bill
This home vs. every recent Sparta sale · assessed ÷ market

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