Trailers in trailer parks in my rural census designated micropolitan statistical area of Ohio go for 60k at the minimum so there certainly is a lot of modern amenities you would have to accept to live without in the house described in the article. And by modern amenities I mean heat and potentially running water.
This reminds me of a hunting cabin in Alaska you could rent for 100 bucks a month. One room. Wood fire stove. Outhouse. Only an hour outside of Fort Wainwright. Good luck is all I have to say.
