Despite home prices rising at their fastest clip in seven years, Robert Shiller, founder of the S&P Case-Shiller Home Prices Indices, noted that homes are still affordable, and there is no national price bubble. Per CNBC:
"I define a bubble as a time when people have extravagant expectations, and the expectations are driving home price increases," said Robert Shiller, Case-Shiller index co-founder and Yale University professor of economics, in an interview with CNBC. "We don't have the mindset of earlier this century."
"Affordability is still good compared to any time over the last 50 years. Mortgage rates are still around 4½ percent; that's not high. Homes are still roughly, in real terms, where they were 25 to 50 years ago," he said.
