A real estate appraiser is a professional who is qualified to estimate the value of real property. The main role of a real estate appraiser is to provide an unbiased estimate of a home's fair market value. In order to do this, they must have a thorough understanding of both the local housing market and the principles of appraisal. Most appraisers are also certified by the Appraisal Institute, which is the largest professional organization for appraisers in North America.

A real estate appraiser is responsible for estimating the monetary value of a property. They use their knowledge of real estate, as well as recent sales data in the area, to come up with an estimate. Typically, an appraiser will visit a property and take pictures, measure it, and assess the condition. They will also review any recent sales data in the area to get an idea of what similar properties have sold for. From there, they will create a report that includes their estimate of the property's value.
