Basic Appraisal Principles Practice Test

The main principle of appraisal that states lower-priced similar commodities will attract greater demand is known as the principle of substitution. This principle is based on the idea that a rational buyer will not pay more for a property than the cost of acquiring a comparable substitute property. Therefore, if two properties are similar in quality and features, but one is priced lower than the other, buyers are more inclined to choose the more cost-effective option. This behavior reflects the concept that consumers seek value and will gravitate towards alternatives that provide similar benefits at a lower price. Understanding the principle of substitution is vital for appraisers as it helps them assess market value based on what buyers are willing to pay for comparable properties. This principle underlies much of valuation methodology, particularly in competitive markets where consumers have many choices and where price can significantly influence demand.
