Appeal Process

Step 1: Get comparables — 3-5 similar properties with lower assessments. Step 2: Calculate cost approach (land + depreciated replacement cost). Step 3: File formal appeal (deadline typically 30-90 days from assessment notice). Step 4: Hearing — present evidence. Step 5: Possible court appeal if denied.

When Most Likely to Win

Comparable properties assessed lower than yours. Errors in property record (incorrect sq ft, lot size, beds/baths). Major market decline since last assessment. Damage to property reducing value. Different zoning than recorded.

DIY vs Attorney

DIY: $0-100 fees, 6-12 hours work. Attorney: $200-500 typical, 1-2 hours of your time + 5-15% of savings on contingency. Tax consultants: 30-50% of first year savings. DIY most cost-effective for smaller properties.
