The document summarizes how government policies from the 1990s through the 2000s contributed to inflating the housing bubble by: 1) Increasing the percentage of FHA loans with down payments of less than 3% from 13% in 1992 to 50% in 2000. 2) Lowering standards for approving mortgage loans so that the ratio of homeowners with less than 3% down payments increased from 1 in 230 in 1989 to 1 in 7 in 2003 to 1 in 3 in 2007. 3) Government increasingly backing subprime and risky mortgages so that by 2008, Fannie Mae and Freddie Mac alone held or insured 13.4 million while overall government guaranteed over 20 million risky loans.
