Win-win for an elderly seller?

[Amanda G.]

A grandfather is FSBO-ing his deceased mother's house. He had a tenant in it, but didn't get several months rent before they left. He just wants it gone. His thinking is that he doesn't want his heirs getting $200/mo forever, just collect the lump sum and call it done.

The difficulty is that he wants about $20k more than the house is worth in that neighborhood. He is asking $80k, and it is worth $60k (at least to me).

I'm trying to come up with creative ways to get him closer to his asking price over time. I don't want to do an option because I want to make some major renovations to up its value as a rental. I was thinking about opening up the conversation about owner financing again, with some language in the note that it will come due 90 days after he passes or 3 years, whichever is later. is this too weird? Anyone have other ideas I could use to sweeten the deal for him?

He appears to be selling because he wants a lump sum as opposed to the monthly income he is currently getting, he also seems to be in no rush to sell.  Both of these things make it quite difficult for you, I don't think getting more creative would help in this situation, because the seller's motivation for selling seems to be to make things less complicated.  It may not be the answer you want to hear but that is my opinion.
