Forty percent of American households rent their homes, and one-fourth of these renters have no intention of becoming homeowners, according to ApartmentList.com, a San Francisco-based apartment-finding search engine.

Rents in Iowa have increased 18.9 percent over the last two years, according to the report. Click here for more.
