The 272-152 vote reflected a congressional push to send election-year help to struggling borrowers and to reassure jittery financial markets about the health of two pillars of the mortgage market.
Hours before the vote, President Bush dropped his opposition to the measure, which now is on track to pass the Senate and become law within days.
The White House swallowed its distaste for $3.9 billion in grants for devastated neighborhoods. In return, the administration got both the power to throw Fannie Mae and Freddie Mac a lifeline and the legislation Republicans long have advocated to rein in the government-sponsored mortgage companies.
Treasury Secretary Henry M. Paulson and lawmakers in both parties negotiated the final deal. It accomplishes several Democratic priorities, including aid for homeowners, a permanent affordable housing fund financed by the two mortgage companies and the money for hard-hit neighborhoods. The grants are for buying and fixing up foreclosed properties.
The bill would let the Federal Housing Administration back $300 billion in new loans so an estimated 400,000 homeowners who cannot afford their house payments could try to escape foreclosure by refinancing into safer, more affordable mortgages. Lenders would have to agree to take a substantial loss on the existing loans, and in return, they would walk away with at least some payoff and avoid the often-costly foreclosure process.
"The industry really has to step up and use it," said Bruce Dorpalen, director of housing counseling for Acorn Housing Corp., a nonprofit housing group based in Philadelphia.
The plan also creates a new regulator with tighter controls for Fannie Mae and Freddie Mac and modernizes the agency. It includes about $15 billion in housing tax breaks, including a credit of up to $7,500 for first-time buyers, and increases the statutory limit on the national debt by $800 billion, to $10.6 trillion.
