How the free property tax check works
Your property tax bill is really two numbers: your county’s assessed value for your home, and the local tax rate. You can’t change the rate — but the assessed value is an estimate, and estimates can be too high. Studies of assessment data consistently find that a large share of homes are over-assessed, yet only a small fraction of owners ever challenge it. We look up the assessed value for your address, compare it to similar nearby homes, and email you whether your assessment looks high enough to be worth appealing. Free.
What your assessment review includes
Your assessed value: the number your property tax is calculated from
Comparable homes: how similar nearby properties are assessed
Over-assessment flag: whether yours looks high relative to comps
Appeal basics: your county’s appeal deadline and how the process works
Coverage is rolling out county by county — entering your address puts your county in the queue and gets your review processed as soon as it’s live.
Why homeowners check their property tax assessment
- You may be overpaying: an inflated assessed value means a higher bill every single year until you fix it
- Appeal deadlines are short: most counties give a narrow window each year to challenge your assessment
- Your escrow & mortgage payment: property tax is baked into most monthly payments — a lower assessment can lower it
- After buying or building: new construction and recent sales are common triggers for an over-assessment
- Fairness: if similar homes on your street are assessed for less, that’s grounds to ask why
Frequently asked questions
Is the property tax check really free?
Yes. The over-assessment review is free — no credit card and no hidden fees. We don’t sell your information to agents or contractors.
Where does the assessment data come from?
County assessor and GIS records — the same official source your property tax bill is based on. Your review names the county source so you can verify it yourself.
How do I know if my home is over-assessed?
Compare your assessed value to what similar nearby homes are assessed at. If yours is meaningfully higher for a comparable home, you may be over-assessed — which is exactly what the review checks and flags for your address.
Can I appeal my property taxes, and how much could I save?
Yes — every county has a formal appeal process, usually with a filing deadline once a year. Homeowners who successfully appeal an over-assessment can lower their annual bill. Your review includes your county’s deadline and how the process works so you can decide whether it’s worth it.
Do you file the appeal for me?
The free review tells you whether you likely have a case and how your county’s process works. If you want help filing, we can point you to appeal specialists who typically only get paid if they win — but the review itself is yours to use however you like, with no obligation.
Is this the same as looking up my house square footage or lot size?
Related but different. Your assessment is the county’s dollar value of your property; lot size and building square footage are the physical measurements behind it. If it’s your roof you want measured, our free roof measurement tool works from satellite right now.
