Which of the following is NOT a characteristic relevant to an appraisal?

The appraiser's personal preferences are not a characteristic relevant to an appraisal because professional appraisals must be objective and based on factual data rather than subjective opinions or feelings. An appraisal seeks to determine the market value of a property based on observable characteristics and comparable sales, ensuring a standardized and impartial assessment.

In contrast, the other characteristics—size of the property, neighborhood amenities, and the property's condition—are all critical factors that directly influence the value of a property. The size impacts potential uses and overall marketability, neighborhood amenities can enhance desirability and comfort for potential buyers, and the condition affects the functional utility and long-term maintenance costs related to the property. Each of these elements is grounded in measurable or observable data, making them integral to accurate appraisals.
