The main purpose of this legislation, known as the Homeownership Eligibility Reform Act, is to ensure that only U.S. citizens can access certain types of mortgage insurance and financing options. Specifically, it aims to restrict eligibility for mortgage insurance provided by the Federal Housing Administration (FHA) and for the purchase and securitization of mortgages by Fannie Mae and Freddie Mac to American citizens only. Key provisions of the Act include amendments to existing laws that govern mortgage insurance and the operations of Fannie Mae and Freddie Mac.
