There are occasionally problems with showing occupied units such as smells, disorder, etc.

Only occasionally.

We've got some areas that have some really nice older homes that I occasionally take a look at.

What I got back from one of the cities is a list of code enforcement complaints from neighbors of problem properties who have made complaints ranging of all sorts of things such as burnt lawns, overgrown vegetation, abandoned cars left on driveways, furniture being left in the front yard, occasional building permit issues.

Occasionally it is nice to pick up the rent ready property (maybe 1 in 10) just to get the instant cash-flow.

BiggerPockets has been great for meeting other local investors and we occasionally get together for coffee.

Schools do, occasionally you'll find a teacher/professor that doesn't.

I have several of these streams so occasionally sell one or more and invest in something else.

We do this occasionally when we make a private loan if the deal is too "thin" we will also tie up another property in the investor's portfolio to ensure performance.And having the props "owned" by your LLC is not the same as having the financing originated and vested in the LLC.

Also sometimes things don't look like a good deal, but when you make the offer at such a lowball price occasionally it actually gets accepted.
