Fannie Mae, Freddie Mac and their regulator provided details on Monday for a low down-payment mortgage program, which could open home ownership to thousands of cash-strapped borrowers.

The mortgage-finance companies and the Federal Housing Finance Agency said borrowers could be able to get mortgages with down payments as little as 3%, but noted that the loans will be available only to first-time buyers, buyers who haven't owned a home for at least a few years and those with lower incomes.

Many of the loans will also require borrowers to undergo home-buyer counseling before making a purchase.
