Warren Buffett is a housing bull

Billionaire investor Warren Buffett believes housing is a better investment than stocks right now:

Warren Buffett says along with equities, single-family homes are a very attractive investment right now.

Appearing live on CNBC's Squawk Box, Buffett tells Becky Quick he'd buy up "millions" of single family homes if it were practical to do so.

If held for a long period of time and purchased at low rates, Buffett says houses are even better than stocks. He advises buyers to take out a 30-year mortgage and refinance if rates go down.

His housing recommendation is likely based on the fact that mortgage rates are incredibly low right now. Nationally, home prices are no cheaper than their pre-bubble norm, although it varies depending on where you live.

I believe that some housing markets are far better buys than others. Cities with very high unemployment rates have dirt-cheap home prices right now. Places like Las Vegas, Phoenix, Detroit, and most of Florida have prices below their historical norms.
