Automated Valuation Modeling (AVM) is a term given to home price estimation and utilizes statistical or mathematical applications to assess the value of real estate in moments; single-family residences and condominiums are the subjects of these high-speed estimates. At present, there are some fifteen models, and perhaps a few more, that exist in the United States. Most of these applications have been in the market for a minimum of seven years and some, for as many as twenty years.
