What principle is essential in the adjustment process in the sales comparison approach?

The principle that is essential in the adjustment process in the sales comparison approach is contribution. This principle refers to the idea that the value of a property is determined by the contribution of its individual components or features to the overall value of the property.

In the sales comparison approach, appraisers analyze comparable properties that have recently sold in the market. To make accurate adjustments when comparing these properties, appraisers must assess how much each unique characteristic—such as the number of bedrooms, the condition of the home, or any additional amenities—contributes to the value of the property being appraised. If a comp has a feature that significantly enhances its value compared to the subject property, an adjustment will be made to reflect that contribution.

Understanding contribution allows appraisers to quantify how different elements of a property enhance or detract from its overall value, making it crucial for determining the adjusted sale price of comparable properties, which ultimately leads to a more accurate estimate of value for the property in question.
