I wouldn't go up more than once a year for a walk through and make sure to set that expectation upfront with the tenants.

Photos, permits, a Clue report, walking inside tells a good deal of what exists.

To make a long story short, after handling my business at my property I simply walk over and ask him......Me: "how long are we gonna do this?

We chose to walk away and let him take it off our hands for about a $40,000 profit after expenses.  

If you're doing a BRRRR (which I don't recommend doing from far away if not experienced), having honest contractors walk properties for you.

Maybe walk through a few of their properties before agreeing to anything

In addition to this you should also walk all of the units.

If you're not familiar with the area, I would  come for a weekend and drive/walk through areas you might be interested in.

I rode around and managed to find a few people working on rehabs and found out who they were renting to, rents they were getting, and one guy was kind enough to walk me through his rehab project.
