"Nationally, McMansions are falling out of favor," notes Francesca Faris, a spokesperson at Trulia. "In just a decade, according to our recent report on McMansions , the median price per square foot on a home that is 3,000 to 5,000 square feet has dropped from $623,966 in 2006 to $599,483 in 2016. While McMansions aren't necessarily losing favor in Rochester Hills, MI, some of the drop in value could be due to the fact that the home lost its newness."
