Please help! Need ideas to help make this deal work

[Trevor Carlson]

Thank you for reading this post and giving any ideas you have. 

My wife and I have a relative who would like to sell their property to us. This is a second property for them with a buildable second lot attached. Although this is a 2nd residence, they moved into it a few years ago so they could fix up their primary residence. However, they have settled in to this property and are having difficulty taking action to get their primary residence ready to move into and getting ready to move out of this property.

I have been trying to think of creative ways to make the purchase while allowing them some latitude in allowing them to stay for a time at least. But I need to fix the place up and maximize rent as soon as possible to make the purchase make financial sense. Any ideas?
