In Tucson, one in eight homes vacant

"The number of vacant homes and rentals has exploded 52 percent in Pima County in the past 10 years, thwarting a housing market recovery and driving even some middle- and upper-income neighborhoods into decline.

An Arizona Daily Star analysis of U.S. Census Bureau data shows the spike in unoccupied homes and apartments has pushed Pima County's vacancy rate from 9.4 percent of housing units in 2000 to almost 12 percent in 2010. That means about one in eight homes or apartments in Tucson is vacant."
