The term "hybrid" in valuation refers to which of the following?

The term "hybrid" in the context of valuation commonly refers to an appraiser assisted valuation model. This approach combines elements of both technology and traditional appraisal methods. In a hybrid valuation, an appraiser utilizes automated tools and data analytics to enhance their valuation process while still applying professional judgment and expertise. This integration allows for a more comprehensive and accurate assessment of property value.

The other options focus on specific valuation methodologies or statistical techniques. Simple linear regression and multiple linear regression are forms of statistical analysis used to model the relationship between variables but do not inherently include the appraiser's expert involvement that characterizes a hybrid model. Mass appraisal is a method used primarily for property tax purposes and often relies on automated processes without the personalized touch of an appraiser. Thus, the definition of "hybrid" as relating to an appraiser assisted model is clearly aligned with the characteristics that define hybrid methodologies in valuation.
