Why is the cost approach typically considered less reliable when appraising a 40-year-old home in an active resale subdivision?
- Estimating accrued depreciation on an older structure becomes increasingly difficult and subjective
- Land cannot be valued separately from the improvements
- The income approach always supersedes the cost approach for older homes
- Older homes have no reproduction cost that can be meaningfully estimated by a qualified appraiser at all
Show answer & explanation
Estimating accrued depreciation on an older structure becomes increasingly difficult and subjective — As a structure ages, accurately measuring accumulated physical deterioration, functional obsolescence, and external obsolescence becomes harder and more subjective, reducing the cost approach's reliability compared with ample recent sales data.
