“Pitch a tent and check the place out for at least four regular weeks, and at least three holidays.
Then go down to the local pub and have a beer, check that there aren’t too many alcoholics, then ask about local legend.
Then you need to go down to the local library to read about the town’s history and if the house or nearby houses have been haunted.
Then listen in on police radio for at least a combined radio-time of 40 hours, to see if there is a lot of crime in the area.
Then you check the sex-offender registry, and get the information of each of the tenants of the building. After that you stalk each of them at least one work day, and one full weekend. Then you go on TOR and find some Russian hackers, pay them to hack the tenant’s and landlord’s social media to see what they’ve been up to.
After that all you need to do is make a freedom of information-act request for the JFK case, to be perfectly sure your neighbours-to-be weren’t involved.
Then move back with your parents, the only safe place in existence.”
