I got an answer from someone I have known all my life and who lives on the Navajo reservation in a hogan. He said it shouldn't take more than a few thousand dollars to build a simple home with a small kitchenette and a bathroom. He is a handyman.
The thing is if I e-mail him back, he probably won't reply for a year. That's how he is. He used to be a friend of my grandpa when grandpa was alive, so he's really old too.
A simple home with a kitchenette and bathroom for a few thousand dollars?
I had stayed at this hotel one weekend. easyupload.io/c2890m
Each cabin had two queen beds, a full-sized bathroom and a kitchenette. The owner told me each cabin had cost him only $10,000. This was about 5 years ago.
