Potential Seller finance deal

[Leonard Leon]

In my neighborhood a multifamily property is going to be going for sale. But before it hits the market I'd like to contact the seller and propose seller financing. I've never done this but have heard of it before. I'm wondering if any one has done this? And if you have what has helped sway the seller to go this route? What kinds of questions did you ask to find out their motivation? Any help/advice would be more than appreciated!!
