Am I asking the right question on a Duplex?

[Tyson Hosey]

I found a Duplex that is FSBO, and I'd like to do owner financing. But I want to make sure that they're understanding what I'm talking about. I know it's a rental unit already, it sounds like the current owner has a pretty good financial situation, because it's getting low rents (lower than market), the property is listed below market and a ton of repairs were just made to the property.. so I want to negotiate down a little bit for my own finances, and have the owner carry the note.

How should I be phrasing this to the owner? "carry the note"? "owner finance"? or just lay out the details of what the deal would look like, so there's no confusion over the terminology?
