GMAC's mortgage-lending unit will continue to make home loans after the company receives a promised $6 billion federal bailout.
"We will continue to originate mortgage products that can move in the secondary market," GMAC spokeswoman Gina Proia said in an e-mail, referring to a lender's ability to sell loans to securities investors.
"We are in a more stable position to conduct servicing operations."
Residential Capital, GMAC's home loan unit, wrote $46.3 billion in mortgages in the first nine months of 2008, making it the seventh-largest U.S. mortgage lender, according to Guy Cecala, publisher of Bethesda, Md.-based Inside Mortgage Finance.
ResCap is also the sixth-largest among U.S. mortgage servicers, which collect monthly payments from borrowers.
GMAC, the Detroit-based lender owned by General Motors Corp. and Cerberus Capital Management, ran short of cash after losing $7.9 billion over five quarters, mostly from defaults on subprime mortgages originated by ResCap. GMAC applied to become a bank holding company so it could gain access to the Treasury Department's Troubled Asset Relief Program.
Subprime mortgages were available to borrowers with damaged or incomplete credit histories.
The $6 billion in federal funding for GMAC is in addition to the $13.4 billion that the Treasury Department agreed this month to lend to GM and Chrysler, also a unit of Cerberus, a New York-based buyout firm.
