I have decided to pass on the house and not bother with an offer. The house needs a lot of work and is all smoked up, not worth it in my opinion even without its history.
There is a house nearby my parents looked at that was the scene of a messy suicide back in the 70s, the original owner who I believe was a Vietnam Veteran used a shotgun, very sad situation. The house was only two years old when it happened and the only reason we knew its history is we knew the people that owned it, they bought it from the widow of the guy that killed himself. They lived there for over 30 years and enjoyed the house greatly.
The house where I lived during much of my childhood was built in the 1880s and has at least 3 natural deaths occur in it that I knew of, both my grand parents and my great grandmother passed there. This was during the 60 years that the house was owned by my family who bought it in 1950, so there was over 60 years of unknown history. I do know that there was a fire in the house prior to 1950 but I don't know how bad it was or if anyone passed because of it.
I will say in that house there was a bedroom on the second floor that always made me feel uncomfortable, even as an adult. Maybe it was just a carryover from my childhood, but even at 30 years old it really bothered me, it is just something I cannot explain other than it felt like someone was watching me. I am not sure if I believe in the paranormal or not.
