And there are also property managers for self storage facilities, retail, office buildings, etc.

This could include tips for cleaning, when/where to return the keys, when you will inspect, when they can expect the deposit back (based on the law, not your personal schedule), etc.

Any advice or tips would be greatly appreciated.

All really good points and tips.

I think the first thing to do is sit with a really good lender, I have one in my office I love, Paige Solberg at lending concepts.
