Which valuation approach relies most heavily on the principle of substitution?

• A. Cost approach
• B. Diminishing returns
• C. Sales comparison
• D. Income approach

Answer: (C)

The principle of substitution says buyers won’t pay more for a property than the cost of obtaining a close substitute. The sales comparison approach uses this idea most directly: appraisers identify recently sold, similar properties (comparables) and adjust for differences to estimate value, reflecting what buyers would be willing to pay for a substitute on the market. The other methods rely on different foundations: the cost approach is based on how much it would cost to replace or reproduce the property minus depreciation, the income approach on how much income the property can generate (capitalization), and diminishing returns is an economic concept about how adds of value from improvements taper off rather than a valuation method. So the sales comparison method best embodies substitution in practice.
