Owner Financing or New Loan

[Robert Littke]

Ok, I'm going at re post this because it disappeared and in the BiggerPockets abyss. So here goes the lengthy explanation (Again).
I have a client with a $230,000 mortgage on a $260,00 home and a 6 month old bankruptcy, credit score of 670. She wants to move to and has someone interested in her home who has a $300,000 home they own outright. My client is interested in taking over the buyers home but has been told by a lender she probably wont qualify for a loan for at least 36 months. What are her options, that would best protect buyer and seller. Pro's/Cons. (The homes are in different states)
