I guess I am questioning why you would want to invite trouble by supporting illegal activity? 

I am looking to potentially put together and invite high level local investors to a mastermind group to share ideas on business/investing/personal and professional growth/mindset/scaling. 

The police will come and remove them from the house as soon as I call, even if they are a legal "tenant" with a lease.t @Joe Kelly, Nah, the "squatters" were invited to move in by the former tenant before he moved; so perhaps "off lease tenants" is a more accurate characterization.

Most loans will have numerous clauses that convert non-recourse to recourse under a wide variety of circumstances.

There are numerous investors, agents, etc. on BiggerPockets with experience in CA who would be able to give you a better perspective on the types of investments that work there.WIth regards to RentToRetirement, I worked with Zach and his team for my first property, detailed in the link below.

I'd also invite you to post the question on our facebook page.

If the person they invest with doesn't have this, it's dirty and probably dead from the start.Competence - What do you know about the deal you're inviting people to? 

That's why it's really important to think about all the things that could go sideways and set your standards before inviting them to sign it.

I provided my phone number, email and a welcome invitation to contact me with any issues they had.  

I was a tenant for 10+ years in numerous properties and learned real quick you rarely get a full deposit back.
