US mortgage giants Fannie Mae and Freddie Mac are developing new types of loans to help borrowers with high-risk mortgages avoid losing their homes.
The general US housing market has seen a slowdown
The move comes amid turmoil in the sub-prime lending market, which offers higher priced loans to people with low wages or poor credit histories.
With US home repossessions hitting a record high last year, the situation has caused concern on Wall Street.
The two firms are looking at "more consumer-friendly sub-prime products".
Sub-prime mortgages are typically variable rate, starting with a low interest rate which can then rise sharply.
Fannie Mae and Freddie Mac said they were aiming to introduce new 30-year, and possibly 40-year, fixed rate deals, with the chance for existing sub-prime customers to switch.
Their announcement came after a high-level group of mortgage industry executives, federal officials and bankers met to discuss the difficulty in the sub-prime market.
They have agreed on a goal of keeping deserving borrowers with high-risk mortgages in their homes.
"It is going to be a very challenging task...we've not going to be able to save everybody," said Sheila Bair, chairman of the Federal Deposit Insurance Corporation.
The downturn in the sub-prime market has led to a number of specialist firms in the sector also falling into financial difficulty.
New Century Financial, one of the largest sub-prime lenders in the US, filed for Chapter 11 bankruptcy protection earlier this month.
Wall Street is concerned that the weakness in the sub-prime market, which is also reflected in a general slump in the US housing market, could spread over into the wider economy.
