What Is an Economic Obsolescence Appraisal?
An economic obsolescence appraisal is a property valuation that specifically identifies and quantifies the loss in value caused by external factors beyond the property owner's control. Appraisers use this analysis to determine how much a property's market value has been reduced by economic, environmental, or regulatory changes in the surrounding area.
Appraisal Methods
Professional appraisers use three primary methods to measure economic obsolescence:
- Matched pair analysis: Compares sale prices of similar properties, one affected by the external factor and one not, to isolate the value impact
- Income capitalization: Measures the reduction in rental income or increase in vacancy rates caused by external conditions and converts the income loss into a property value reduction
- Cost approach adjustment: Deducts economic obsolescence from the property's replacement cost after subtracting physical and functional depreciation
When an Economic Obsolescence Appraisal Is Needed
- Property tax challenges: To support a petition to the Florida Value Adjustment Board for a reduced assessment
- Eminent domain proceedings: To demonstrate consequential damages to remaining property when part of a parcel is taken
- Insurance claims: To document value loss from environmental contamination or other covered events
- Litigation: To support damage claims in lawsuits involving property value diminution
- Loan modifications: To demonstrate reduced collateral value to lenders
Florida Property Tax Applications
Florida property owners can use an economic obsolescence appraisal to challenge their county property tax assessment. The petition is filed with the Value Adjustment Board during the annual review period. The appraisal must demonstrate that external factors have reduced the property's market value below the county's assessed value.
