Need Some Guidance on a Flip

[Naveed Q.]

I need some advise on a opportunity I received today. I have a very motivated seller who wants to sell her house as she is late on her mortgage payments ,owe HOA and back taxes. I am looking to flip this property as the numbers are there.

The option that I am most interested in is where we start making the mortgage payments on her behalf while we do the rehab work, sell the property and settle all the dues at the time of closing. She just want to get rid of the property. 

Need input as to how we can structure this deal.
