For this principle to apply effectively, there must be equally desirable substitutes that are available for potential buyers. This means that if a buyer is considering a property, they will look at other similar properties to determine what they would be willing to pay based on the competition in the market.

Having accessible and comparable options allows buyers to make informed decisions, supporting the rationale behind the principle of substitution. It is crucial that these substitutes are equally desirable, as significant differences in quality, features, or location would alter the comparison and value assessment. This principle is foundational to market analysis and helps ensure that appraisers evaluate properties fairly by benchmarking against directly comparable alternatives.

Unique features may enhance a property's appeal but do not facilitate a direct comparison necessary for the principle of substitution to be applied. Historical trends may inform the market context but do not fulfill the requirement for the existence of substitutes that can affect pricing decisions. Thus, the
