Frequently Asked Questions
How do I know if my property is over-assessed?
Compare your assessed value to recent sales of similar homes (same size, age, condition, neighborhood). If your assessment is 10%+ higher than comparable sales, you likely have grounds for an appeal. Check your county assessor website for comps.
What is the success rate for property tax appeals?
About 50-70% of formal appeals result in some reduction. Having 3-5 comparable sales supporting a lower value significantly increases your chances. Many homeowners never appeal, even when over-assessed.

Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
