America's Abandoned Cities

July 25, 2009— -- The big news in Kansas City is the Chiefs' off-season acquisition of quarterback Matt Cassel. Filling in for injured superstar Tom Brady in New England last season, Cassel became a starter for the first time since his senior year of high school.

When trading for a backup quarterback is cause for citywide celebration, it's a sign of a metropolis starving for good news--and perhaps an indicator that other troubles are afoot.

Indeed, the Kansas City metro area tops our list of America's Abandoned Cities. In Kansas City, rental vacancy rates rose from 11.9% to 15% over the past year; homeowner vacancy rates nearly doubled, up from 2.1% to 3.8%. Comparatively, the average homeowner vacancy rate in the country's 75 largest metro areas improved slightly from 3% to 2.7%, while the rental vacancy rate edged up to 10.2% from 10% a year ago.

Kansas City isn't the only metro where rental and homeowner vacancy rates are rising in tandem. Second on our list is the San Francisco-Oakland metro, where high prices are pushing Bay Area residents out of the region. Third is Tucson, Ariz., where the aftermath of the housing boom has left a glut of inventory. The pair's predicament illustrates both sides of the vacancy coin.

Many of the cities on the list are still digging themselves out of the wreckage of the real estate bubble. Miami, which ranks No. 8, owns a whopping 12.7% rental vacancy rate, up from 11.4% a year ago; residential towers built in the final stages of the boom now stand as empty monuments to an over-hyped market downtown. Homeowner vacancy stands at 5.6%, up from 3.8% last year, thanks mostly to a spate of foreclosures. According to Trulia.com, 40% of the homes available in Miami's city limits are foreclosures.

To form our list, we looked at vacancy data from America's 75 largest metropolitan statistical areas and metropolitan divisions (or metros)--geographic entities defined by the U.S. Office of Management and Budget (OMB) for use by federal agencies in collecting, tabulating and publishing federal statistics.
