Investor Warren Buffett, CEO of Berkshire Hathaway,appeared yesterday on CNBC’s “Squawk Box” saying that buying single-family homes is such a great investment right now, if it were practical, he’d buy a couple hundred thousand of them. Given how low rates are for a 30-year fixed-rate mortgages (3.95 percent, according to the Freddie Mac Mortgage Index), Buffett told CNBC’s Becky Quick that homes, held over the long term, provide a better investment than stocks. If you factor in that prices in some areas are at a 10-year low and inventory levels are high, the conditions are ideal for buying.
