This mod has a total of 4 new homes, as well as 3 purchasable upgrades for the Atomic Wrangler Room. The 4 homes are entirely free, whereas the upgrades cost anywhere from 800-1000 caps each. I also threw in a map marker just outside the Atomic Wrangler for convenience.
Just a quick look at the outside of each home. I have to say that the Small Farmhouse was my favorite to work on.
