This is not as passive as it is thought to be, but can be profitable and fun if you run it like a business. 

Specifically- in 1 year I made $100k in equity + net cash flow of $700/month with 2 properties.2) Who do I gain access to by investing in this program?

But how much do you need to invest in real estate and generate steady passive income?

Yes, it’s passive but I like to say it’s passive aggressive!

The increase in property taxes, insurance, and maintenance/wear and tear may erase all of your gains and more. 

I never scaled beyond a one-person operation but was doing an average of just under two deals per month over the course of about three years before I shut it down to focus on more passive opportunities and partnerships.

It certainly isn't next to passive like LTR'S  can be.Vacation rentals can also be very rewarding and fun to own.

To start, a passive investor would never consider co-hosting so I can’t even answer that question as people have mentioned these are businesses. 

However, this model can be beneficial for folks wanting real estate exposure in a more passive manner.Thoughts?

This also allows you to be involved and gain experience for the future.
