Back when I was managing my own units, I would have said yes to this arrangement. 

Or can I have a separate contract arrangement agreeing to that with just one person on title ?

@David Trevino, have you talked to lenders about this arrangement?  

I assume either you're looking at a larger building or it's an office share-type arrangement where individuals and small businesses are renting small offices/suites/desks.

Even Those that I reached out to when arranging for large problems like flooding or no ac in summer go back to the PM once the problem is solved.

May I ask how you arrange to have traveling doctors and nurses stay at your Airbnb?  

There are no written contracts for any arrangements made between the two parties. 

I have possible arrangement with my brother.

If you are keeping the same residents and want them on a new lease, make sure you give proper notice of rent increase, (in my market its 30 days for a mtm tenant and 60 if they are on a lease) and a good strategy that I got from these forums is to increase it the most for a Month to month arrangement, and to increase it less for renewed lease.  

I've never heard about this strategy before and curious if anyone has done it, pros/cons, and what the execution of such an arrangement is like.
