Is there any specific documentation or legal process I should be aware of to ensure a smooth and legally sound transaction?

The only change is where we might slide a bit and allow a marginal tenant in with 1 month rent as deposit, we're having to really be strict and insist on a high deposit. 

The properties are running smoothly overall and we continue to see great rent appreciation year over year.

We may both be in the same industry and in the same markets (although different parts of town), but I can tell you that they have a great reputation for running a smooth operation without a lot of drama.  

By having reserves and promptly addressing necessary repairs, we can maintain tenant satisfaction, encourage lease renewals, and ensure smooth operations.

Whenever you are buying a property out of state you should do a few things to ensure it's as smooth as possible.

Then it is a sliding scale down to the worst homes in the worst areas rented last. 

I've done UD before COVID, and it was quite smooth, but not this time.ThanksJames

In over 5 years there we have had one issue with a stolen phone but beyond that it has been smooth sailing.
