Property the one I'm currently working is really old property, they build on 1948.
Some building so much going on in the past 62 years , like people die from natural age, drug related, suicide, etc. and some they discover it couple days or weeks later by neighbors.
One day I was inside some building working on the furnace, I smell something weird from the floor at the front of furnace closet and I have strange feeling for it, so I continue to work on the furnace and try to ignore the smell.
When I get back at the office, I was told years ago the guy shot him self in the head and discovered three weeks later already decomposed

(Even the paramedic can't stand from the odor and view when they remove the body)
I don't believe in ghost but when I was in some place like that, sometime I have strange feeling
