How to propose seller financing or a subject to?

[Megan Arzt]

I know just enough to be dangerous but not enough to not get myself into trouble. I have a lead on a place that the owner would consider some sort of alternate financing. He still owes about $250,000 on the property. What sort of alternate proposals could I offer up to him?  And then how do I go about setting that up? I've heard a lot about subject to an even looked into it a bit but I'm still very fuzzy on it. Thanks!
