U.S. metropolitan residential real estate markets are peaking, and some cities are in another pricing bubble, according to the latest national index produced by Florida Atlantic University and Florida International University faculty. The Beracha, Hardin & Johnson Buy vs. Rent Index scale goes from minus-1 (good time to buy) to 1 (better to rent) with zero being neutral. Two metropolitan areas—Dallas (0.92) and Denver (0.77)—are significantly overheated and rapidly approaching a score of 1, said Ken Johnson (above), one of the index’s creators and associate dean and professor in FAU’s College of Business.
