Winning strategies

3 Arguments That Win Protests

1

Plead both grounds

Always check both "value over market" AND "unequal appraisal" on Form 50-132. Unequal appraisal (§41.43) is often stronger — CADs must prove your value is at or below the median of your comparables.

2

Request the evidence packet

File a written HB201 request for all CAD evidence. If they fail to deliver it 14 days before your hearing, that evidence is excluded at the hearing (§41.67(d)).

3

Show up to the informal

60–80% of Texas protests settle at the informal stage before reaching the ARB. Bring printed comps and a one-page summary. Appraisers settle when the data is clear.
