Many homeowners believe that they have the strongest insight into the value of their home; after all, only they understand all of the blood, sweat, and tears (and money) that have been put into countless maintenance and improvement projects over the years! Other people are certain that computer-generated automated valuation models (AVMs), with their access to millions of data points from the overall market, comparable properties, and buyer tendencies, can give estimates that no human can match. So which side is actually better at valuing a home, the owner or the AVM? As it turns out, there isn't really much of a difference between the two options, partially because neither is very good at the job!
