Appraisal districts assess hundreds of thousands of homes using models that aren’t always accurate. Texas law gives you the right to challenge yours. With the right comparable data, the process is more straightforward than it looks and could save you hundreds. Enter your address to see how your appraisal compares to similar homes nearby and generate your protest documentation in minutes (for free!).
From address to filed protest in four steps - all free, no account required.
Search for your property by street address. We pull live data directly from your county appraisal district's public records.
We find similar homes in your neighborhood and calculate adjusted values using standard Texas appraisal methods.
If your appraisal is higher than the adjusted median of comparable properties, you have grounds to protest under §42.26(a)(3).
Generate a complete evidence package - pre-filled Form 50-132, comp analysis, and legal argument - ready to submit to your appraisal district.
The models they use aren’t always accurate - and the corrections only happen when someone files a protest. If you’ve challenged your appraisal before and want stronger evidence to work with, this tool gives you the comparable data and adjusted analysis in seconds. If you’ve been meaning to file but weren’t sure where to start, it walks you through the whole process and generates your filing packet for you. Either way, you’ll know exactly where your appraisal stands before you commit to anything.

Texas law requires that your property be appraised at the median level of appraisal of a reasonable sample of comparable properties. If your appraisal district has appraised your home higher than that median - even if the value seems "fair" in the market - you are legally entitled to a reduction. This tool identifies comparable properties in your neighborhood, applies standard Texas adjustment methodology for differences in size, features, and age, and tells you whether you have grounds to protest. The full methodology is shown on the analysis page.
Everything you need to know before you start.
This tool is built for two groups of Texas homeowners: those who already protest their own appraisals and want better comparable data and documentation to work with, and those who have been meaning to protest but found the process too daunting to start.
If you've filed a protest before, you already know it's worth doing - this tool gives you the same depth of analysis in seconds that would otherwise take hours to pull together manually. If you're filing for the first time, it walks you through every step and generates your complete filing packet automatically. Either way, you'll know exactly where your appraisal stands before you commit to anything.
We're Texans who believe every homeowner deserves access to the same protest tools that professionals use - not just those who can afford to pay $50–$80 in flat fees or give up 40% of their savings to a commission firm.
We keep our costs low by using publicly available data from each county's appraisal district. Voluntary donations help us cover operating costs and expand to new counties, but the service will always be free to use.
We currently support Williamson County and Brazos County. We're actively working to add Harris County, Travis County, and additional Texas counties. If your county isn't listed yet, check back soon.
In Texas, the general deadline to file a protest is May 15, or 30 days after your appraisal notice is mailed - whichever is later. Missing the deadline typically means waiting until next year.
Check the deadline printed on your official appraisal notice, as it may differ slightly by county or property type. Don't wait - the process takes only a few minutes with this tool.
No. Texas law gives every property owner the right to protest their own appraisal and represent themselves at the Appraisal Review Board (ARB) hearing. No license, agent, or legal representation is required.
DIY is a completely legitimate strategy and the approach this tool is designed to support. The ARB process is an administrative hearing, not a court proceeding - there's no legal complexity that requires an attorney. The evidence that matters is straightforward: comparable properties and the numbers behind them.
Professional protest firms charge either a flat fee ($50-$80+) or a commission of 30-40% of your first year's savings. With this tool, you keep 100% of whatever you win. The packet we generate is built on the same methodology those firms use.
Yes - if you have a valid case, this tool simplifies the process to protest yourself. Just enter your address, review the comparable properties the tool finds, and download a ready-to-file evidence packet. The whole thing takes most people under 10 minutes.
The ARB process itself is also more straightforward than most people expect. Many protests are resolved at an informal hearing before you ever see the full ARB panel. Showing up with well-organized evidence is often all it takes. The tool walks you through exactly what to expect at every step.
The tool pulls live data directly from your county's public appraisal records and applies the same adjustment methodology appraisal professionals use under Texas Tax Code §42.26. It's not a guess - it's the same math.
That said, the ARB makes the final decision, and outcomes vary depending on the comparable properties available in your neighborhood and the strength of your specific case. The tool will tell you upfront if the data suggests you have strong grounds to protest.
