Kerch: Mortgage rates may not surge again from here

"The days of easy credit are behind us. The days of really low mortgage rates may be behind us," too. But Steve Kerch, MarketWatch.com's real estate editor, tells Steve Potisk this week's spike higher in average rates may have "been one bad week given all that we've seen in financial markets." Kerch adds that if rates remain in the current range, topping near 6 1/2 percent, that's not bad.
