Radical transparency

Everyone else hides the numbers.
We show you all of them.

Source-labelled property data

Assessment, tax, recorded-sale, listing and AVM fields are identified by what the provider actually returned—so records and model outputs are never presented as the same thing.

Full math shown

We don't just give you a “score.” We show every calculation and comparison so you can verify the logic before you spend a dime on an appeal.

We say no if it's no

If your assessment is fair or actually low, we'll tell you immediately. We won't sell you false hope or an appeal packet you don't need.

How it works

Simple. Transparent. Fair.

Questions

Frequently Asked Questions

In most jurisdictions, an appeal reviews whether your assessment is too high — it does not raise it. We only recommend appealing when the data shows you are over-assessed, so you are not exposing yourself to risk on a weak case.

When you move forward to purchase a full Appeal Packet ($29.00), we automatically deduct the $4.99 you already paid for the check. You will only pay the $24.01 balance at checkout.

You receive four editable, organized deliverables: a Filing Guide, source-labelled Evidence Packet, Cover Letter, and one combined PDF. Comparable count depends on available provider data, and any unverified local deadline or form is clearly marked for confirmation.
