CNN - "Mortgage defaults: Latest woe for housing" (2-12-07)

"Just as the struggling real estate market seems to be stabilizing, a fresh problem is brewing far from real estate offices or home construction sites: a jump in defaults by higher-risk borrowers."

"News of rising default rates by buyers with less than stellar credit could put a crimp in financing for home purchases - and prices. That's because the rapid growth of new types of mortgages was one of the key factors behind the boom that sent home buying, and prices, to record highs for five straight years through 2005."
