The county appraiser's staff is required to visit your real estate property at least once every four years. First, they will try to visit with the owner to review the current information. Then an exterior inspection is done where they will look for changes, such as, adding on a room, a garage or a deck. They will verify the dimensions, checking for structural damage, and the property's current condition.
Back in the office, the appraiser's office uses computer-generated data to analyze the property based upon its age, size, and style of construction and replacement costs. Sale prices of similar properties are also analyzed.
