When I moved to Michigan a few years back, I had to find roommates and a property to rent, knowing nobody. I went through that pain but it I was able to apply learnings to my rent by room house hack a couple years later.
Some tips:
-I use Craigslist to find roommates with a "room available" or "looking for roommates" ad. In the ad I give a brief background about me / the other roommates to give candidates an idea about who they would be living with, but do not bias when selecting final candidate. (FB marketplace works as well).
-screening process is same between normal rental and room rental.
-the lease is gospel. It can be same as a normal rental lease, with tweaks for roommates. And you can use a roommate agreement form as well. Things like keeping common areas clean and clutter free, wash dn dry dishes within xx hours of use, guests can stay a max of xx hours, etc.
I've never had an issue finding roommates in metro Detroit. Seems like most people looking for rooms are under 35. Every ad I post gets at least a dozen initial responses . My suggestion would be to post a test ad on Craigslist to gauge demand. Keep in mind this time of year is really slow for onboarding renters but it can still give you an idea.
