People who bought a house that needed work - what horror or funny stories have you got?

I'm in process of buying a house that needs some work - new kitchen and bathroom etc. It's scary.

I was partially inspired by my sister and her husband who bought a house in Lithuania long time ago, she could barely afford it. It was abandoned, previously owned by a lady who used to bury beds and pets in the garden. She used to walk around the property and glare at us, creepy. The house had no plumbing or heating (outhouse only) - they had to dig a septic tank when they got it. While doing that, one of the walls in the hole crumbled and a human skull fell out...

Of course police got involved, turned out it was a child of the previous owner, they couldn't afford the proper funeral costs. Despite all this my sister kept the house and did get to fully renovate it. It's lovely now.

Surely, I thought, my story can't be worse 😂 anyone else got some weird stories?
