My mother and I owned a rental together. It was a nightmare. First off we sucked at it. If there is a list of what not to do as a landlord, we filled it.
We had no intentions of being landlords it just happened as we could not sell the house in this market.
We rented the place out twice and both tenants ended up leaving our rental a mess. The first tenant was completely bizarre. She only lived in the house 5 weeks! She didnt turn on any utilities and the neighbor called me one day to let me know she had a moving van in the driveway. She was moving out in a hurry. The neighbor who I had a good friendship with parked his truck in front of the driveway blocking her in. She called me and asked if I knew the neighbor as she needed to leave for work. I said really, I hear you are moving out. She was pretty shocked and confessed that she needed to leave and gave me this long list of excuses. Personal stuff like her ex bf's mother was stalking her and this was going on and that...The woman was a nut. Since she had been a nightmare from day two (refusing to get the utilities turned on in her name, taking in a dog when I said no etc etc), I told her to get out. When I went to the house it was hit. I was in complete awe how someone could trash a house in as little as 5 weeks.
The carpet was trashed, she ripped the oak banister off the stairs moving her bed out, everything was filthy. She left a bunch of junk behind, walls had odd stains on them and the best part the whole place was infested with fleas. As soon as you walked in the house you see and feel them crawling all over you.
So it took us a couple of months to get the house back into shape. We find another idiot, he stopped paying and we sent eviction papers. Same thing, moved out in a hurry. This guy did bigger damage. He busted the cast iron sink in the kitchen. I have no idea how. Didnt even think it was possible. He wrote all over the mirrors with a black sharpie. Just like a little kid would do. He wrote odd sayings and pictures of stuff. The house was filled with empty liquor and beer bottles. The carpet was hit. We tried to sue him and found out he had several lawsuits pending.
That was enough for us. We are not landlord material. We put the house up as a short sale and took the hit. I have no idea why someone would trash a rental. All I can say is a person that cares only about themself and lack intelligence.
