As owners continue to walk away from their homes because of loans they can’t afford, foreclosures rose to .83% of all outstanding mortgages for the end of 2007. This is versus .54% for 2006. This has contributed to a rapid fall in home prices. The central bank estimates that home values decreased by $533 billion during Q4 2007 alone. With this problem growing more dire, Fed Chairman Ben Bernanke has called on lenders to reduce loan amounts in addition to previous calls from President Bush and Treasury Secretary Henry Paulson to modify note rates.
