Boulder, CO, United States

Capital City

Home prices have skyrocketed 60% since 2010 to $648,200, and growth is severely restricted by a gauntlet of zoning laws. The city of 108,250 residents is a liberal enclave surrounded by gorgeous mountains, but bureaucracy and Chinook winds are persistent headaches. With its highly educated, younger-than-average population, Boulder is best suited for those who can afford the high cost of living and don't mind the occasional bitterly cold winter.
