If you are able to get a loan, real estate is ‘as affordable as it gets’ according to data from Moody’s Analytics. Home affordability has returned to pre-housing bubble levels or even fallen below the average in many U.S. markets.

In September 2010, the ratio of home prices to annual household income had fallen to 1.6–below the historical average of 1.9 between 1989 and 2003. The ratio peaked in 2005 at 2.3.

“Based on incomes, this is as affordable as it gets,” says Mark Zandi, chief economist at Moody’s Analytics. “If you can get a loan, these are pretty good times to buy.”

Some of the most undervalued markets include Cleveland, Detroit, Las Vegas, Atlanta, and Phoenix.

But those cities also are facing high rates of foreclosures and more borrowers defaulting on their mortgages that could decrease values further in those cities before they start to improve, Zandi says.

In Phoenix, for example, “it’s become cheaper to buy than to rent,” Jon Mirmelli, a real estate investor in Scottsdale, Ariz., who rents out foreclosed homes, told The Wall Street Journal. “But the question is: can you qualify for a loan?”
