If you are in foreclosure then you need to find out if it is backed by Freddie Mac, Fannie Mae of HUD (FHA). You can visit: freddiemac.com, fanniemae.com or hud.gov. You can also call the federally funded HOPE for home owner's line for advice: 888-995-4673.
If your loan is a "portfolio" loan, meaning the bank owns the note then you will need to call the bank / lender and ask them if they would consider working with you to modify.
