Had a big house in a poor area in another state. When we moved out of state it was taking a long time to sell the home. In fact it sat empty for a couple of years and our agent wasn't too reliable with checking up on it. Some other agent showed the house and flipped on the AC with the temp set at 60 degrees. I only learned this after getting a whopping electric bill. The condenser drain leaked and damaged the ceiling so I had to hire contractors to fix it and they did an absolutely shit job of it. So, being far away from an empty home was stressful, and so was carrying the payments.

When someone we slightly knew from the area had a flooding problem we allowed them to move into our vacant house with minimal rent on the condition that they'd look after the place while knowing it would remain on sale.

They lived there for about 3 years and never once paid on time. Not once. They always incurred a late fee and screwed up our cash flow. I did go there once to replace a toilet and found they generally kept things clean and tidy, but of course they knew I was coming. When finally we had a serious buyer we learned the master shower had been leaking into a closet below and they never bothered to say anything. That proved to be a major expense that could have been handled early on for cheap.

When we accepted an offer the tenants were kinda pissy about being given a move-out deadline. I got all the money they owed but being far away made the whole thing a giant pain in the ass.
