Market value estimate AVM
An automated estimate of what your home would sell for today, from an address-level valuation model, so you have a number to weigh the assessment against.
Property tax over-assessment check
Assessors value millions of homes with formulas, and plenty come out above what the house would actually sell for. When the assessment is high, the tax bill is high, year after year, until someone challenges it.

What is in the report
Your assessor already published the assessed value. This report puts it side by side with an independent market estimate and the comparable sales, so you can see the gap and act on it.
An automated estimate of what your home would sell for today, from an address-level valuation model, so you have a number to weigh the assessment against.
The taxable value the county has on file for your property, the figure your bill is calculated from.
If the assessment sits above the market estimate, roughly what that gap is costing you each year at your local tax rate.
Recent sales of similar nearby homes, the core evidence an appeal board expects to see.
Where appeals are filed in your area, the kind of deadline to watch for, and how to present the comps.
An honest read of your odds, what an appeal can and cannot do, and when it is worth the effort.
Why it is worth a look
Property tax is charged every single year on the assessed value. If that value is too high, you keep overpaying until you challenge it, and a successful appeal can lower the bill for years, not just once. Most homeowners never check, because the number looks official and the process looks daunting. This report hands you both halves: the gap, and the evidence.
How it works
We pinpoint your specific property, not just your ZIP code or street.
We estimate market value, read your assessed value, gather comps, and work out the gap.
Your gap, estimated overpayment, comps, and a plain-English path to appeal, in seconds.
Questions
It is an automated valuation model (AVM), the same broad approach behind the estimates you see on real-estate sites. It is an estimate, not an appraisal, and it can be off, especially for unusual homes or thin local sales data. We show it as a range and pair it with real comparable sales so you can judge it for yourself. For a formal appeal, some boards prefer a licensed appraisal, and we say so in the report.
Sometimes. If your assessment is genuinely above market value and the comps support that, an appeal can reduce the assessed value and therefore the bill, often for several years. But outcomes vary by county, by how your area assesses, and by the evidence you bring. We give you an honest read of the gap, not a guarantee. This report is not legal or tax advice.
No. This is a report and evidence pack, not a filing service. It gives you the gap, the comps, and the steps so you can file the appeal yourself with your county, which most homeowners can do without a lawyer or a contingency-fee firm taking a cut.
The market value estimate comes from an address-level valuation model, and comparable sales and property details come from public and licensed real-estate data. Assessed values and tax rates come from public assessor and tax records where available. We list our sources on the Sources page.
Then the report tells you that too, and you can stop worrying about it. Knowing your assessment is fair is worth something. If the gap is small or the comps do not support a challenge, we will say the case is weak rather than talk you into a filing that will not go anywhere.
Coverage is best in areas with good public assessor records and sales data, which is most of the US. If we cannot build a meaningful report for your address, contact us and we will refund you.
