Homeowners who can't afford their mortgage payments can get a better deal from their lender. But the process is complicated and potentially onerous, and concessions are offered only to borrowers who earn neither too much nor too little income to meet the lender's guidelines.

"If they can afford to pay, they should pay. If they can't afford to pay, we need to make sure they have a fighting chance to make the new payments and pay back the loan over the long term," says Thomas Kelly, a spokesman for J.P. Morgan Chase, which also owns the Washington Mutual, or WaMu, and EMC brands.
