This home's payments are about right
It sits inside Alpine's normal range — market price changes haven't singled it out. No case for a tax appeal.
Step 1 · Market value
Likely range $3,134,013 – $3,704,063, from 10 comparable Alpine sales in the past 18 months, at this home's 4,969 sq ft.
Step 2 · The Director's Ratio
The state's official measure of how far Alpine assessments sit below market value — republished every October, applied town-wide. A $3,480,289 home should be assessed near $3,349,430.
Step 3 · Assessed value
Set at the last town-wide revaluation and mostly frozen since. That's $911,930 below what the ratio math suggests (27.2%).
