WASHINGTON — The Bush administration, trying to deal with a worsening housing slump, announced a new initiative Tuesday aimed at helping homeowners about to lose their homes. For qualified homeowners, it will put the foreclosure process on hold for 30 days.

Dubbed "Project Lifeline," the new program will be available to people who have taken out all types of mortgages, not just the high-cost subprime loans that have been the focus on previous relief efforts.

The program was put together by six of the nation's largest financial institutions, which service almost 50 percent of the nation's mortgages.

These lenders say they will contact homeowners who are 90 or more days overdue on their monthly mortgage payments. They will be given the opportunity to put the foreclosure process on pause for 30 days while the lenders try to work out a way to make the mortgage more affordable to the homeowner.

"Project Lifeline is a valuable response, literally a lifeline, for people on the brink of the final steps in foreclosure," Housing and Urban Development Secretary Alphonso Jackson, said at a joint news conference with Treasury Secretary Henry Paulson.

He said the goal was to provide a temporary pause in the foreclosure process "long enough to find a way out" by allowing homeowners and lenders to negotiate a more affordable mortgage.

Paulson said that the new effort was just one of a number of approaches the administration was pursuing with the mortgage industry to deal with the country's worst housing slump in more than two decades.

In December, President Bush announced a deal brokered with the mortgage industry that will freeze certain subprime loans, those offered to borrowers with weak credit histories, for five years if the borrowers are unable to afford the higher monthly payments as those mortgages reset after being at lower introductory rates.

"As our economy works through this difficult period, we will look for additional opportunities to try to avoid preventable foreclosures," Paulson said. "However, none of these efforts are a silver bullet that will undo the excesses of the past years, nor are they designed to bail out real estate speculators or those who committed fraud during the mortgage process."

Lenders will begin sending letters to homeowners who might qualify for the new program in coming days. Homeowners won't qualify for the program if they have entered bankruptcy or if they already have a foreclosure date within 30 days or if the home loan was taken out to cover an investment property or a vacation home.

The Mortgage Bankers Association reported that at least 1.3 million home mortgage loans were either seriously delinquent or in foreclosure at the end of the July-September quarter.

Private economists are forecasting that the number of foreclosures could soar to 1 million this year and next, about double the 2007 rate.

Officials did not have an estimate of how many people might be helped by the new "Project Lifeline" program.

Democratic critics said the administration was still not doing enough to help with a serious crisis which has slowed the overall economy to a near standstill and raised worries about a full-blown recession.

In a statement, Sen. Hillary Rodham Clinton, who is running for the Democratic presidential nomination, said that last year she had called for a 90-day moratorium on subprime foreclosures. She said the administration has been slow to react to the unfolding crisis.

"The administration's latest initiative is welcome news, but more remains to be done," she said in a statement.
