Unequal Appraisal vs. Market Value Protests: Which Argument Wins?

When you protest your property's appraised value in Texas, you're not limited to a single argument. State law actually gives you two distinct grounds to challenge your value, and understanding the difference can significantly change how strong your case is.

The Two Arguments, Explained

Market value is the argument most people think of first: "My home isn't actually worth what the appraisal district says it's worth." You support this by showing recent sales of comparable properties that sold for less than your assessed value.

Unequal appraisal is a different, separate argument: "Even if my value is close to market value, I'm being appraised higher, relative to actual value, than similar properties around me." Texas law requires appraisals to be equal and uniform. If your home is appraised at 100% of a defensible market value while comparable homes nearby are appraised at 85–90% of theirs, that's a legitimate basis for protest even if your number isn't technically wrong.

Why the Difference Matters

These are not just two ways of saying the same thing. They can produce very different results depending on your situation.

• If home prices in your area have recently dropped or plateaued but your appraised value went up anyway, market value is usually your stronger argument.
• If your neighborhood was appraised unevenly (common after a mass reappraisal, or in older neighborhoods where some homes haven't been reassessed as aggressively as others), unequal appraisal can succeed even when your market value estimate is roughly accurate.
• In many cases, the strongest protests present both arguments together, since the appraisal district and ARB will consider each independently, and having two lines of evidence gives you more paths to a reduction.

Building Evidence for Market Value

• Pull 3–6 recent comparable sales (ideally within the last 6–12 months, within roughly a half mile to one mile, similar size, age, and condition).
• Adjust for meaningful differences. A comp with a pool, an extra bathroom, or a recent renovation isn't a clean comparison without adjustment.
• Document any condition issues on your own property that reduce its value relative to those comps: deferred maintenance, foundation issues, outdated systems.

Building Evidence for Unequal Appraisal

• Most Texas appraisal districts publish appraisal ratio data or make comparable appraised values searchable through their own online systems.
• Identify a set of similar properties near you and compare their appraised value per square foot to yours.
• If your per square foot appraised value is notably higher than similar, nearby homes, that gap is your evidence. You're not arguing your home is worth less, you're arguing you're being taxed unevenly relative to comparable properties.
• Screenshots or printouts of these comparisons, organized clearly, work well as hearing evidence.

Presenting Both at a Hearing

You don't have to pick one argument and abandon the other. A clean approach:

1. 1Open with your unequal appraisal comparison if the gap is clear and well documented. It's often the more objective, harder to dispute argument.
2. 2Follow with market value comps as supporting evidence, especially if your own condition issues or recent local sales strengthen the case further.
3. 3Keep both sets of evidence organized separately and clearly labeled. Appraisers and ARB panels see a lot of protests, and organized evidence gets taken more seriously than a stack of printouts.

A Note on Which Argument to Lead With

There's no universal answer. It depends on your specific market and neighborhood. In a fast changing market with a lot of recent turnover, market value evidence tends to be more persuasive because there's more recent data. In stable, established neighborhoods where reappraisals have been uneven over the years, unequal appraisal often carries more weight. If you're unsure, gathering evidence for both before your hearing costs little extra time and gives you flexibility to lead with whichever looks stronger once you see the actual numbers.
