seller financing

[Rasheed Hope]

I have a seller who's willing to do a seller financing deal, the thing is I don't have a clue how to structure a deal like this. He has a mortgage on the property of around 76k and a second of around 10k. The property is worth about 215k and needs roughly 15k in rehab. He's willing to sell the property to me outright for 165k but I'm not sure that's a good enough deal for me to wholesale. Anybody have any input I'll be happy to listen.
