This is a big red flag to me because obviously someone in the investing game would have trustworthy contacts to do those types of things for them they wouldn't just ask some stranger on a forum.

if you bring strangers together in an investment your creating a security and as such you should contact a securities attorney .. usually 10k or so for the documents you are asking about.

Thinking it may be dIfficult to get 3 strangers to rent the 3 bedrooms together.

It is still a people business and you can't trust unless you have verified. 80k should not be treated lightly, sight unseen with strangers you may have better odds at a casino!

I've spent a good part of my career in sales so I'm perfectly comfortable talking to and "selling" strangers and the pieces and parts of this business are starting to click for me. 

You'll get all kinds of strange (and often wrong) answers from strangers that don't have a clue what your state law says.Read this attorney blog or this article.

My fav was when the UWM trolls put fliers on all the cars in the Quicken HQ parking lot showing their retail v wholesale rate sheets with a message that said something like "who treats strangers better than friends?"

Instead of bringing strangers into the property in a sublease situation why not just get rid of the current broke guy and find a new tenant that can afford your property ?

I say should because I'm still only using funding from my personal network and have not had to approach a stranger for funding yet.  

To introduce a non vetted, temporary stranger into their space who would not be subjected to that would undermine what I have created.
