1. Tenants lived upstairs for 3 months, didn’t pay the third month’s rent, called in (as me) to cut off my utilities, reported me to Children’s Division for child abuse… moved out leaving 18 bags of garbage & reported me to the fire department for the garbage hazard.
2. I had a tenant pour concrete down the drains. There was no repair possible. It was literally more cost-effective to demolish, salvage what we could and rebuild. It even got into the septic system and we had to settle with the city for damaging their infrastructure. Biggest nightmare ever. We sued the former tenants, but when you’re suing a scumbag, best case scenario, you might get a 1990 Toyota Tercel.
Tenants are pretty decent as a whole, but if you have to evict, it’s worth it to just offer them a couple hundred dollars cash to move out while you’re there and can watch the whole process.
