Since the housing crisis began in 2008, approximately 4.6 million homes were lost to foreclosure, according to CoreLogic. The vast majority of those homeowners became renters. Even as housing recovered, credit tightened, pushing even more potential buyers out of homeownership and into rentals, both apartments and single-family rental homes.
There are now 43 million renter households, or 35 percent of all U.S. households, the highest rate in over a decade for all age groups, according to Harvard's Joint Center for Housing Studies; 4 million more renters today than there were in 2007. For those aged 25 to 54, rental rates are the highest since the center began record keeping in the early 1970s.
As a result, rental vacancies have fallen dramatically, and rents have skyrocketed.
