Besides the mandatory educational grade, which can vary from Finance to Construction Technology, most, but not all, countries require appraisers to have the license for the practice. Usually, the real estate appraiser has the opportunity to reach 3 levels of certification: Appraisal Trainee, Licensed Appraiser and Certified Appraiser. The second and third levels of license require no less than 2000 experience hours in 12 months and 2500 experience hours in no less than 24 months respectively. Appraisers are often known as "property valuers" or "land valuers"; in British English they are "valuation surveyors". If the appraiser's opinion is based on market value, then it must also be based on the highest and best use of the real property. In the United States, mortgage valuations of improved residential properties are generally reported on a standardized form like the Uniform Residential Appraisal Report. Appraisals of more commercial properties (e.g., income-producing, raw land) are often reported in narrative format and completed by a Certified General Appraiser.
These appraisers also perform valuations on commercial property ranging from single to multiple tenant office buildings, shopping centers, retail, industrial, malls, hospitals, health care facilities, warehouses, and hotels to multi-family apartment buildings, co-ops, senior housing, condominium developments, and even vacant land, agricultural, and golf courses. Regardless of the property type or local zoning, they'll determine the highest and best use of the project and assess the value using the actual or projected cash flow from the property's rent roll and financial statements, using both cap rates for capitalizing year one net operating income (NOI) and discounted cash flow (DCF) of multiple future income streams. If you're a commercial lender, investor, builder, contractor, architect, or agent, you'll want to use these appraisers to conduct a feasibility analysis of any income producing real estate project you may be considering. They can also help consult on construction costs and projected absorption rates. They generally produce a commercial narrative appraisal when engaged for any commercial assignment.
