No one can speak to a room of 100+ people and give any meaningful advice beyond the very basics about anything.  

Run to your room and quickly build a website (before you bleed to death).A rattle snake just bit you in your left buttcheek? 

I'm currently house hacking three rooms in my house and in my opinion it is a great idea.

That way when you do become 'bankable' for conventional loans, you personally have more wiggle room both from a Debt-to-Income ratio perspective (bc the loans in his name aren't counted against you) and from a loan limit perspective (can only have 10 conventional).Feel free to reach out with more questions!

The only one in which the K-1 indicated dividend income was in an HML fund that converted to public REIT, which was a grand-slam for the investors till Covid took a little bit of luster off the shine.

It sounds like a tough property/project that can't be sold with traditional bank financing, so honestly the seller needs to allow enough room in the purchase price to compensate the buyer for taking the project on.

Originally, I was looking for a "house-hacking" situation with either a small home + attached living space (basement apartment, etc), or renting out rooms in a home I own and occupy. 

So much of the "how to" in REI can be answered with some consideration, slipping on the other parties shoes for a spin around the living room and a bit of consideration of how things look from that other side of things, asking yourself what would be wanted if in that other position, and that generally answers it. 

The first time I did it, the house had a detached garage with a ~380sq ft room above it. 

Today I was speaking with a friend about maximizing cash flow on my rental properties and he came up with a BRRR method minus the last R and I thought it seemed like a good idea.I currently have 2 rental properties and both are paid for.One is a small house that I have about 15k into and it cashflows about 500 per month.The other is a quadplex that I have about 70k into and it cash flows between 800 and 1500 per month (one room is an airbnb).
