Seller Finance newbie

[Tyrel Rose]

Hello Bigger Pockets,

I am in the middle of working my first seller finance deal and have come upon some questions that I need help answering. I have no experience with this type of financing so I am a bit out of my lane but hopefully not for long. 

I have found a For Sale By Owner single family in an area that is familiar to me. The seller is willing to finance but they still owe a mortgage on the property, What steps do i need to take to make this deal happen, and how do I protect myself so that i can ensure that the mortgage is getting paid to the bank so I dont lose the house?

Thank you for all the help.
