The proportion of U.S. homes listed at or above $1 million is steadily growing. Between 2014 and 2017, seven-figure-plus abodes increased from 3.2 percent of U.S. listings to 4.3 percent. While that number might not sound enormous, the increase has had an outsized impact on certain urban areas. Realtor.com ranked more than 900 metro areas by their rate of increase in million-dollar listings over the last three years, excluding already-pricey towns like Aspen and San Francisco.
As it turns out, Colorado is home to two of the top-three towns where the proportion of seven-figure listings has grown the most. Denver, Colorado, which has a booming tech scene and burgeoning pot industry, leads the list with a 6.1 percent increase in its proportion of million-dollar homes. Just three years ago, Denver was a solid middle-class market. But by the first quarter of 2017, nearly 1 in 10 Denver homes hit the $1 million mark.
