“This isn’t a forecast, but it’s a worry,” Robert Shiller, founder of the index, told unwilling ears on CNBC, “that home prices might drop substantially from here foreward, once this government support is taken away… Mortgage rates will go up, the economy might double dip, the expectations for housing -- which helped drive the markets -- might change suddenly when people see the support being withdrawn. Some people were buying because of the homebuyer tax credit. When that’s withdrawn, a lot of people will be absent the market. There is substantial downward risk right now."

“But on the other side,” he added, unable to control laughter sprung from true insanity of it all, “we’ve seen a bubbly nature in the market recently. So I think just uncertainty is at a maximum right now.”
