How can I make this deal work?

[Michael Grant]

My aunt has a home that she owes about  $50,000 mortgage left on the property. She wants the home out of her name  and currently her brother is currently renting it from here and he has bad credit, but have the funds to continue to pay. He wants me to take over the house in my name and he pay me . How can I make this work and get the property when my finances are not available right now. The home is currently valued at about $180,000.
