This document summarizes the author's experience as a young appraiser over 35 years ago when cell phones and computers were not available. The author describes an instance where one of their staff members was given an address for an appraisal assignment but due to a digit error in the address, inspected the wrong property, a community center, and spent hours measuring it before realizing the mistake. The staffer then had to contact the correct property to do the inspection, wasting valuable time. The moral of the story is to verify address details before visiting a property to prevent inspecting the wrong building and save time.
