Gary Thayer: About to touch the housing bottom

"If you're talking about a bottom in sales, it could happen late this year or early next year," says Gary Thayer, a senior economist at Wachovia. "If you're talking about a bottom in pricing that may take a little bit longer to hit." Thayer tells John Wordock he's watching first for sales to bottom. "We're not there yet. But we're getting some encouraging signs."
