Sell My Property

My husband deserted me and my daughter and his name is still on the contract. He gives me no $$ support. I gross only $2300/mo. A mortgage broker told me my debt to income ratio is too high to get a loan and that my credit score, 545 is too low. They want $180/k for the house and they want me to pay the property taxes, $2700 and since my husband left me with the financial burden and I don’t have his whereabouts. I hate this bind I am in, can anyone give me some advice? My payment is $1000/mo and I am living on paycheck advances to buy food because of the high house payments which are not being credited to anything, really…The mortgage holders are lawyers and are having the payments taken out of my paycheck through a collection company and aren’t even having the payments reported to the credit bureau to help improve my credit score? I need a quick solution since my husband has been gone for 7 months now. Help?????
