When property is being sold, bought, or evaluated for a loan or estate, someone who does not have an interest in the transaction must consider its value. A real estate appraiser provides that objective analysis. The appraiser inspects the property, considers its location, and does research. He or she might interview people who have a connection to the property, and examine public records. Both the condition of the property, and recent sales of similar properties are factored into the calculation. The appraiser takes pictures of the outside and inside of the property, too. Then a written report is prepared. This is a job for people who enjoy getting away from the desk, to inspect property and conduct research. But an ability to develop a clear written report is also important. Some appraisers are salaried employees of banks, insurance companies, or other financial institutions. Others are independent contractors. For example, the heirs of a property owner might commission an appraisal when the owner dies, to re-set the value of the property for tax purposes. Some vocational schools offer courses in real estate appraisal, but most people working as appraisers have additional experience in fields that give them knowledge that helps them evaluate property. For example, it helps to know about building and construction materials, or the history of a neighborhood. Real estate appraisers are licensed in most states. They take a National Uniform Appraiser Examination, which is offered monthly.
