How to make an owner finance offer?

[Terre B.]

How do I present an offer for an owner carry? There is a mobile home, not on land, so it cannot go FHA. Owner wants $50K. I asked if he'd consider owner carry, and he indicated it would depend on the down. I mentioned 20%, and he wasn't excited. Mobile home financing I can find is 12% for 23 years, so I'm wondering if there is a better way. I'd like to go 10% down, 10% interest, with maybe a balloon?
