Appealing a commercial property tax assessment in DeKalb County requires a strategic, evidence-based approach. Commercial valuations are complex—often involving detailed analysis of income, expenses, and market conditions. If you suspect your assessment is too high, understanding the appeal process, valuation methods, and necessary documentation is essential to building a successful case.
Commercial assessments often go beyond comparable sales:
Income Capitalization: Based on actual or potential rental income, operating expenses, and a market-derived capitalization rate.
Cost Approach: Considers what it would cost to rebuild the property, minus depreciation.
Sales Comparison: Used when valid commercial comps exist, though adjustments for features, leases, or condition are critical.
Commercial buildings often have unique uses, tenant mixes, and income streams that require specialized valuation.
Assessors use mass appraisal models, which may not fully reflect your property's specific financials or condition.
Check for errors in property characteristics (e.g., square footage, zoning).
Look at the Fair Market Value (FMV) listed for January 1 of the tax year.
Review rent rolls, vacancy history, and actual expenses.
Challenge the county’s assumptions about market rent, expenses, or cap rate.
Confirm depreciation, construction type, and land value are accurate.
Show economic or functional obsolescence if applicable.
Research recent sales of similar commercial properties in DeKalb County or neighboring submarkets.
Adjust for features, location, tenant quality, or lease structures.
📑 Lease agreements, income & expense statements, cap rate surveys.
📷 Photos showing deferred maintenance or external obsolescence.
📈 Independent appraisals or expert testimony from brokers or consultants.
