My current house is a delapidated mobile home I bought for $800, gutted, and am completely re-doing the inside using lumber from the old house and other scrounged and beautiful materials.
I'm only at the land three days a week and was having terrible problems with rats and mice getting between the walls, chewing up wiring and generally making a mess and even getting into the house and chewing up rugs and so forth. Very destructive little creatures. I didn't want to poison them, and I hate traps that sometimes maim but don't kill. So I built a pole barn around the mobile home.
