If you have money, you can just go visit the old missile silos, build a nice home underground elsewhere, and still have a bunch of money left over that you didnt spend trying to renovate an old ruin not really meant for people to live in. For example, there's one of those old missile silos that a guy runs scuba diving tours out of. Apparently it's very cold, but interesting. Trying to remember what show it was on, maybe Abandoned on Vice?
