Principle of substitution
The maximum value of a property tends to be set by the cost of acquiring an equally desirable substitute.
Substitution is the foundation of the sales comparison approach and the reason comparables matter at all. Related principles include contribution, which measures what one component adds to the whole, conformity, progression and regression.
See it in a question
One question from Valuation and Analysis, so the term lands in the context the exam uses it in.
An appraiser values a 40-year-old single-family home in an established neighbourhood with many recent sales. Which approach carries the most weight?
Written to DRE's published topic list. Not a real examination question, since reproducing those is a misdemeanour under B&P Code section 123.
