Three steps, three tests, one packet.
Everything on this page is what happens when you enter an address. Nothing is hidden behind the fee.
- Step 1 · 10 seconds
Enter your address
We find your parcel in the county’s certified roll and read the assessed value from it. Nothing is stored about you until you choose to save the report.
- Step 2 · a few seconds
Read the verdict
We select comparable homes by fixed rules, compute the medians, and run three tests. The verdict, the estimate and the math show free.
- Step 3 · $49, under a minute
File the packet
If it is worth filing, we build the county-specific packet. You file it online or by mail; the county page says how.

Each comparable home is adjusted to yours with the district's own values: your land value, plus the comparable's building value per sq ft times your living area (the equal-and-uniform method boards apply under Tex. Tax Code §41.43(b)(3)). Same neighborhood or nearby, similar size and age, from the county roll read 20 Oct 2026. An estimate from public records, not a promise: the review board decides.
