Step 1 · Market value
Likely range $549,313 – $744,827, from 12 comparable Berkeley sales in the past 18 months, at this home's 2,197 sq ft.
Step 2 · The Director's Ratio
The state's official measure of how far Berkeley assessments sit below market value — republished every October, applied town-wide. A $643,652 home should be assessed near $340,814.
