Nobody made loans "under the CRA program" CRA is not a loan program. It sets numerical targets for lending by location, race, and ethnicity. CRA often required lending to uncreditworthy persons to get a satisfactory CRA rating, and it did indeed cause Freddie and Fannie to take on huge amounts of dreck. "The chief executive of Countrywide Financial, the nation's largest mortgage lender, is said to have 'bragged' that in order to approve minority applications, 'lenders have had to stretch the rules a bit.'"There never were laws that would prevent lenders from making bad loans. Nothing was deregulated by the Bush Administration in that regard. Lenders did their best to not make bad loans.
Then the Clinton Administration rewrote the CRA to REQUIRE loans be made to low credit quality borrowers. And engaged FNMA and FRE to buy these loans.
In order to make loans and homes more affordable for lower income borrowers the unusual loan products were developed. Interest only, Option ARM, and the low teaser rate products were answers to helping people who did not otherwise qualify get a home, as REQUIRED by CRA. These low standards for qualification were applied to everyone who wanted a mortgage.
This is not even close to my thing...
