Which of the following is a component that would typically influence an appraiser's report?

Historical sales data is a key component that significantly influences an appraiser's report. This data provides appraisers with essential context about what similar properties in the same area have sold for, allowing them to make informed decisions regarding a property's value. This comparative analysis helps establish a baseline for pricing, ensuring that the appraisal is grounded in real market trends rather than subjective opinions. By relying on historical sales data, appraisers can create a more accurate and credible evaluation of the property being assessed.

In contrast, unverified employee records, agent marketing strategies, and owner personal preferences do not serve as reliable or objective sources of information for appraisal purposes. Unverified records may lack credibility, marketing strategies are often subjective, and personal preferences do not reflect the intrinsic value of a property on the market. Hence, they are not considered typical components influencing an appraiser's report.
