Because much private, corporate, and public wealth lies in real estate, the determination of its value is essential to the economic well-being of society. It is the job of the professional appraiser to determine these values by gathering, analyzing, and applying information pertinent to a property.

Unquestionably, the professional opinion of the appraiser, backed by extensive training and knowledge, influences the decisions of people who own, manage, sell, purchase, invest in, and lend money on the security of real estate. And because the appraiser is trained to be an impartial third party in the lending process, this professional serves as a vital "check in the system," protecting real estate buyers from overpaying for property as well as lenders from over lending to buyers.

The appraiser gets his or her information from a wide variety of sources, including the local Multiple Listing Service, local tax assessors records, local real estate professionals, county courthouse records, private public record data vendors, interviews with sellers and buyers, appraisal data co-operatives and his or her own personal knowledge or office files from previous appraisals. The quality and reliability of each piece of information is considered by the appraiser.
Typically, an appraiser needs to document the condition of the property, both inside and out, from the layout and features to degree of modernization including any updates as well as the overall quality of construction. This information will help to assist the appraiser throughout the valuation and comparison process.

The appraiser estimates the square footage (GLA - gross living area), by measuring the exterior of the home. Non-living areas, such as garages or covered porches, aren't included in GLA, but are accounted for and considered in value seperately. Finished basements are also calculated separately from the above-ground GLA. The local market will dictate the contributory value of the finished basement, which can be influenced by governmental regulations, the degree of modernization, the quality of the finish, and other factors.

The appraiser will generally consider only permanent fixtures and real property. Because many above-ground swimming pools and small sheds are not permanent structures, they typically usually aren't included in the valuation. Depending on the specific installation process and local custom, however, an above ground pool or small shed might be considered part of the real property.
