You're likely better off attending your local REI meet-up to see if you can find an investor who has house-hacked or is currently house-hacking their primary home.

@Kevin Hoover, with certain types of entities it is possible to contribute property to and distribute property from that entity without triggering a tax event. 

Makes me think they could be too busy taking care of a new baby to attend to guest issues? 

The sooner you regain control, prove that you fully intend to enforce the terms of your lease, and that you will not be 'played' by their recall of events or documents, the more effective this action will be.  

This might give a one-time (non-scalable) boost to cash flow, offer multiple value-add options, and allow the house-hacker peace of mind, via the assumed mortgage, in long-term breakeven or positive cash flow in the event that the value-add plans end up not being executed, and/or the person has to move out, and rent by the room or STR become unavailable for some reason at a future date.

Advice is for you to do this for another 5+ yrs to go through some real ups and downs to get a better sense of realized cash flows (net turnovers, evictions, capital events, etc). 

Search online for “real estate meetups” and check their websites for their upcoming speakers.Networking events.

In my opinion, the best "first step" is to find a local REIA to attend. 

The energy in person is different for me, and I've made some of my best connections and friends at Chicago meetups.Here is a list of the Chicago event from BP: https://www.biggerpockets.com/forums/521-real-estate-events-...I also have a list of ALL THE CHICAGO MEETUPS that I am happy to share with you. 

@Devan Praska I do not have a manual for my tenants but have created a manual for each of my properties in the event that something might happen to me and someone else would have to take over the management of them.
