The House is expected on Wednesday to pass a $300 billion housing rescue bill aimed at helping troubled homeowners avoid foreclosure and supporting mortgage giants Fannie Mae and Freddie Mac.If the bill is then passed by the Senate and signed by President Bush, who today withdrew his threat to veto the legislation, thousands of at-risk borrowers will be able to refinance their unaffordable old mortgages into new, low-cost fixed-rate loans insured by the Federal Housing Administration.
