That house reminds me of an old house in Arkansas that my parents occupied when they first got married in 1935. The family calls it the "Weener" home, located on the family farm. It's a first home used to be weened off of living at home with your parents to see if you can make it by yourself. I assume it was rent free, a financial advantage to support yourself and simply put food on the table. You can see it at 1:45 in this video below. This video is my cousins property today, you can see his house earlier in the video.
