Looking for best way to structure an investment

[Andrew Tothill]

Hello,

I have a unique scenario where 3 people are involved in acquiring a property, just looking for the best way to go about it that satisfies all three parties.

Person 1: Bad credit, Mid-40s income, never owned and hoping to buy a home on their own in a metropolitan area (Fixer upper).  

Person 2: Great credit, Business owner with assets, Home owner, family member to Person 1.  Hoping to help Person 1 acquire a home but wants them to pay to a company, not to them. 

Person 3: Great credit, no income, home owner with a small passive income, and capable with home renovation.  Also has a desire to create a home for Person 1. 

How do these three people fairly go about purchasing something for Person 1, but allow person 2 and 3 be able to benefit (even slightly) from the mortgage payments made? A trust, a company? What is the term for a very watered down REIT?

Side note: Ideally this is just the first scenario.  Person 2 and 3 have plans to create a real estate investment company together to add doors / help low income or low credit people get into homes.  Just in case this helps direct the ideas.  Thank you everyone!
