A real estate appraiser assistant provides administrative support to a real estate appraiser or a real estate appraiser’s office. Typically, your duties as an assistant are market research and information gathering to help the appraiser make a proper estimate on the value of a commercial or residential building a client wants to sell. Using internet searches and requesting property and home sale records from municipal and county departments, you collect relevant data and develop an initial appraisal for your boss based on comparable sales in a neighborhood or district. You may have other administrative responsibilities, such as filing paperwork, scheduling meetings and inspections with clients, and taking notes.
