I've got a bit of an obsession with Borley Rectory lately because it's the most famous 'haunted house' in British history and yet when you actually dig into the evidence, it's... surprisingly thin?
The place is famous because of Harry Price's investigations and his books, but Price had a reputation for being sensationalist and for adding details that weren't well documented. Meanwhile the actual phenomena reported were pretty standard poltergeist stuff - noises, objects moving, apparitions. Nothing that couldn't have been explained by natural causes or fraud.
I visited the site a few months ago (it's mostly just ruins now) and spoke to some of the locals in the village. They were surprisingly blasé about it. Didn't really seem to think the place was particularly haunted. Most of the supernatural reputation seems to have come from Price's books rather than from actual experiences.
Genuine question: Is Borley Rectory actually haunted or is it just a case where a sensationalist investigator created the legend?
