The Next Housing Bust - WSJ.com

Everyone knows how loose mortgage underwriting led to the go-go days of multitrillion-dollar subprime lending. What isn't well known is that a parallel subprime market has emerged over the past year -- all made possible by the Federal Housing Administration. This also won't end happily for taxpayers or the housing market.

Last year banks issued $180 billion of new mortgages insured by the FHA, which means they carry a 100% taxpayer guarantee. Many of these have the same characteristics as subprime loans: low downpayment requirements, high-risk borrowers, and in many cases shady mortgage originators. FHA now insures nearly one of every three new mortgages, up from 2% in 2006.
