Could more mortgage shopping prevent foreclosures?

"The Consumer Financial Protection Bureau is currently examining how consumers shop for mortgages, which could provide some clues to unraveling the housing crisis. In its first semi-annual report to Congress, the CFPB notes that home buyers are taking on less complex mortgages than they were before the bust, but suggests that many may be reluctant to shop around for the best deal. The implication is that mortgage borrowers might miss potential savings that could make paying off their homes easier."
