You have to go through your lender for the HAMP (Home Affordable Modification Program) program.
The government web site for the various programs is http://www.makinghomeaffordable.gov/ It's possible a HUD-approved housing counselor may be able to help. From the government's web site:
A HUD-approved housing counselor will talk to you about your situation and help you decide what mortgage options are best for you. A counselor will explain what documents you will need to provide to your mortgage company and may be able to contact the mortgage company on your behalf.
If your daughter is delinquent on her mortgage, here's the number to call: 888-995-HOPE (4673)
Hope that helps.
A housing counselor can also help you make a budget so that you can meet your monthly mortgage payment and other expenses. The counselor will have information about local resources that may be helpful to you.
There is no charge to work with a HUD-approved counseling agency.
HUD sponsors housing counseling agencies throughout the country that can provide advice on buying a home, renting, defaults, foreclosures, credit issues, and reverse mortgages.
