How to buy someone out of a property with an outside investor?

[Raquelle S.]

Hello!

Looking to crowdsource some proposal scenarios.  I own a minority stake with my brother in a property that has greatly appreciated.  I won't qualify for a mortgage on the new amount on my own and don't have additional funds to put in, however I can manage the entire project, including building an A.D.U.  There is great opportunity for continued appreciation with the A.D.U., landscaping, maybe a pool, etc. and then rent both the main unit and the A.D.U.  The scenario would ideally include profit sharing / renting out one or both units but it could also include selling the property at a given point in time.  And could this proposal include myself living in the main unit or the A.D.U.? (It doesn't have to but it would be nice).
