Going north can be a bit of a pain to get to I-65 and the airport is a bit small but Southwest is flying out of there now.  

The rules on this stuff is pretty clear, but my knowledge of it is murky as I've generally not taken advantage of this- too much of a pain in the a$$.

I had some family that had rentals when I was young and I thought it was such a pain for them.

In short - get your license.... it's worth it to prevent the pain and hassle of defending yourself in an investigation.At times this business is awesome, and other times it's not incredibly fun - so no matter what niche you pick, you always have to figure out how to mitigate as much risk as you can... and the sandwich scenario you mentioned is fraught with more risk than walking into a room full of angry hornets naked.

The door casing must have been a pain to make considering it probably decreases the value of the home haha.

I'm  new at owning rentals and my current growing pain is on how to collect rent and give notices to tenants.

The pain will PROBABLY pay off.  

Getting super detailed with unique finishes, tiles, or paints causes him pain.

Individually renting rooms sounds like a major pain. 7 rent checks to worry about...Nah just rent the whole thing.
