In property valuation efforts, which principle is NOT included in Brewster's analysis?

In the context of property valuation, Brewster's analysis primarily revolves around principles that directly affect the value of real estate. The principle of location is indeed a fundamental factor in determining property value, as it greatly influences desirability, accessibility, and potential appreciation over time. Factors like proximity to amenities, schools, transportation, and community characteristics make location a crucial component.

On the other hand, desire, utility, and purchasing power are also significant in property valuation, but concepts like utility refer to the property's ability to fulfill the needs of its owner or tenant and thus contribute to its value. Purchasing power relates to the ability of potential buyers to afford certain properties, which actively affects market dynamics and valuations.

In contrast, the exclusion of location from Brewster's analysis presents an oversight, as it is one of the most critical determinants of real estate value. Therefore, valuing property without considering location would lead to incomplete and potentially inaccurate assessments of worth.
