What Is Economic Obsolescence?
Economic obsolescence (also called external obsolescence) is a loss in property value caused by factors outside the property itself. Unlike physical deterioration or functional obsolescence, economic obsolescence results from changes in the surrounding neighborhood, economy, government regulations, or market conditions that the property owner cannot control.
Common Causes
- Transportation changes: A highway rerouting that diverts traffic away from a commercial property
- Zoning changes: New restrictions that limit the property's highest and best use
- Environmental contamination: Pollution on neighboring land that affects property values in the area
- Economic decline: A downturn in the local economy or closure of a major employer
- Market oversupply: Excessive new construction that reduces demand for existing properties
- Neighborhood changes: Increased crime, declining schools, or loss of amenities
Impact on Property Valuation
Appraisers account for economic obsolescence when valuing property. In the cost approach to value, economic obsolescence is deducted after calculating the replacement cost less physical depreciation and functional obsolescence. In the income approach, reduced rental income or higher vacancy rates reflect economic obsolescence.
Florida Property Tax Implications
Florida property owners experiencing economic obsolescence may petition the county property appraiser or the Value Adjustment Board for a reduced assessment. Evidence such as declining rental income, increased vacancy rates, or comparable sales showing reduced values can support the claim.
