My goal with this is so funds are not commingled and protected with lawsuits.

@Michael Frost So what would this mean for property that is under prop 13 protection and was last sold years ago? 

Is there anything else that I can do to protect our relationship and the contract we signed?

The project suffered as the recession gained steam and were never able to sell all 36 units to owner-occupants.

As far as last month rent, that is just protection against a tenant that decides not to pay thier last month.

(Alternatively, bill in advance for $X,XXX dollars to be spent on materials, and then provide receipt tracking for materials bought against that bill, billing additional as needed)The problem I've seen over and over again is that investors will turn contractors into unwilling lenders with none of the protection (Deeds) or benefits (Interest) afforded to a real lender.

There are certain things you can't turn away or it's illegal discrimination, but "AirBnB" is not a protected class like religion or gender or familial status. 

@Jason Kicza, I'm moving further and further away from the idea that a year-long lease offers any protections to the landlord.

What should be stated in the contract to protect myself from losing money?

@Rudy TateI just got this from fundrise:Fundrise Advisors, in our capacity as Manager of the eREITs and eFunds, has determined that it is necessary at this time to suspend the processing and fulfillment of redemption requests.While under normal market conditions, we seek to provide investors with the ability to redeem their investments on a regular basis, during times of financial crisis or extreme uncertainty, it is absolutely critical that we suspend redemptions in order to protect the interests of all our investors.As Manager, we have an obligation to make decisions based upon what is best for the entire Fundrise investor community and must always put the priorities of the whole above any one individual.Fundamentally, Fundrise investors own real property, which is simply not liquid.
