Methodology & disclaimer

A "tax appeal candidate" is a property whose most recent assessed value exceeds its most recent sale price (within the past 36 months) by 15% or more. Estimated annual overpayment is calculated as the assessment gap multiplied by the property's effective tax rate.

This page is informational only. Property-tax appeal eligibility depends on jurisdiction rules, deadlines, and exemptions — consult a licensed property-tax professional before filing an appeal.
