Hi Trent,
I would recommend not doing this in a MF situation. I have owned 3 single family homes and rented out all of the rooms while I lived there which worked well because I could screen the folks and minister everything. I had amazing luck but there were a few instances where I had to resolve disputes.
I just bought (literally yesterday!) my first 4plex and I had the same idea you did because if the income potential but it's honestly just not worth the trouble. I'm willing to bet you would have such high turn over on the rooms that the potential empty rooms would wash out the profit from it being fully rented. If you have the units on leases, you more or less have no worries for that term as opposed to all of the screening and vetting of 8 people on month to month leases.
Now, what I do plan on doing since I am doing owner/occupy, is I will be renting out the 2 extra rooms in my owners unit to bring in about $1100 extra per month and when summer hits, I will have at least one of those units completely furnished and have it set up as an Airbnb.
You could also have one unit dedicated to that for the tourist season.
Good luck sir!
