Step 1 · Market value
Likely range $584,669 – $743,930, from 12 comparable Sparta sales in the past 18 months, at this home's 2,361 sq ft.
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 $645,665 home should be assessed near $386,237.
