A property appraiser is a person responsible for the evaluation of residential real estate and the determination of its value, based on factors like the size of the home, location, comparable homes in nearby neighborhoods, and projected growth of the area. You often work closely with real estate agents, mortgage lenders, banks, and insurance companies to determine the value of various residences. A good property appraiser must have strong attention to detail and be able to build relationship networks with other real estate professionals.
