Current owner wants to rent after sale

[Kyle Soderman]

Hey All! 
Helping my brother go about a purchase of a property and we are brainstorming the best way to structure the deal. Here's the cliff-notes version of the story:

The current owner of the property is going through a divorce but also has a son (the property is across the street from the Elementary school). So the soon to be ex-husband and wife want to sell the property and take their fair shares. The wife wants to stay in the property and rent the home for a few years while the child gets through Elementary. 

Has anyone seen/dealt with a situation like this before? Any tips or recommendations when putting together an agreement?

Thanks!
