3. Appraisal Review Board (ARB) 5-Step Hearing Strategy:
- Collate 4 Copies: Hand 1 copy to each of the 3 panel members and 1 copy to the county appraiser.
- Focus on Facts, Not Taxes: State tax boards have zero control over tax rates; frame arguments strictly on Fair Market Value and Uniform Assessment Equity.
- Stick to the Lien Date: Only cite market transactions and physical condition occurring on or before the statutory valuation date.
- Present Contractor Estimates: Unrepaired physical defects must be supported by third-party licensed bids.
- Politely Rebut County Comps: Point out superior upgrades, square footage variances, or busy road differences in county comps.
