I agree that EO does lower the economic life, but I was referring to the practice of extracting depreciation on a yearly basis. Economic obsolescence is not worse for a 50-year-old property vs a 5-year-old property. It would inherently be the same on a percentage basis (less on a dollar amount basis if calculating physical/ functional obsolescence first). If economic obsolescence is present, extracted depreciation from a sale of a newer property will overstate depreciation on an older property if applying on a per year basis. That is something that I've seen done on ad valorem appraisals quite frequently."economic obsolescence" defines the Great Recession. So I respectfully disagree. EO can crash the effective life when credit seizes up and homes sell for pennies on the dollar. That is the very definition of "economic" obsolescence in my book.
Just making up an example, ignoring FO for simplicity:
Sale 1: 10 years old. 50% depreciated. 40-year useful life, but the implied economic life is 20-years. That indicates that economic obsolescence is 33.33% of the physically depreciated cost.
An appraiser concludes 5%/ year depreciation. Applying that to a 15-year-old property suggests 75% depreciation. BUT, if physical deterioration is 2.5%/ year and EO is 33.33% of physically depreciated cost, total depreciation on the 15-year-old property is not 75%, but 61%.
