Remaining economic life is the appraiser's estimate of the number of years a property's improvements are expected to continue contributing positively to its overall value. It represents the period during which the structure remains functional, competitive and economically viable in the marketplace.
In the cost approach, remaining economic life is used alongside effective age to calculate depreciation and assess the overall condition of the improvements relative to their total economic life. A property with a short remaining economic life may carry significant depreciation, which directly affects the value contribution of the improvements.
Lenders and reviewers pay close attention to remaining economic life estimates, particularly when they appear inconsistent with the property's described condition or effective age. For appraisers, the estimate must be grounded in market evidence and align logically with other condition-related conclusions in the report — an inconsistency between remaining economic life and effective age is a common appraisal review finding.
