This course was created to provide a broad review of basic techniques and procedures for measuring single-family residential dwellings. The measurement and area computation methods are based upon the American National Standards Institute Square Footage-Method for Calculating ANSI Z765-2013. The course is an exploration of the public records system, automated valuation models, and the MLS. Specifically, this course identifies ways in which square footage numbers reported by various sources impact home values. In every residential transaction, at some point and time, a home’s “size” will impact the perception of value.
