Halloween Fun: Anyone Ever Own a Haunted Property?

[Karl B.]

I may have posted a similar thread around Halloween in years past but only because the paranormal and ghost stories entertain me so much!

So the question must be asked: have any of y'all ever had/have a rental, flip, etc. that was haunted or (at the very least) where unexplained, creepy happenings occurred? (horrendously low appraisals don't count!)
