Appraisal practice mainly includes what type of services?

Appraisal practice primarily revolves around the professional process of valuing real estate and other properties carried out by an individual specifically designated as an appraiser. This individual is typically licensed or certified to perform appraisals according to established standards and ethical guidelines. The appraiser's role is to analyze various aspects of the property, including its condition, location, and market trends, to provide an unbiased valuation.

This distinction is crucial because valuation services must adhere to specific regulatory requirements and professional standards that govern the appraisal process. Unlike other options that may involve informal assessments or market opinions provided by non-appraisers, the accuracy and credibility of valuation services depend on the deeply informed expertise of the appraiser. Therefore, the correct answer highlights the necessity of having a qualified professional conduct these essential valuation services, ensuring reliability and validity in appraisal practice.
