Make Mortgage Relief available for families in crisis who can't live together

I have a brain tumor, a divorce pending and share ownership of a house that I had to leave with our 3 kids because my husband refused to move out. We tried to refinance our mortgage so we could rent the house out at an affordable rate to cover the mortgage before selling. Our tenant moved in with a year long lease and monthly payments covering the new mortgage amount, just as the refinance fell through. Because my husband and I had moved out of the house, it became an "investment property' so I was not eligible for help anywhere. Our tenant's rent covers the mortgage less $700 a month but the bank wants all or nothing. Our savings are gone and our income is spent on our own rental accommodation. With my credit rating plummeting and my lease ending soon, foreclosure is looming and possible homelessness. Rentals are hard to find when you have bad credit. My health and children's welfare is at risk as we are falling through the safety net - an exception to the 'Making Home Affordable' eligibility needs to be made on compassionate grounds.
