I have a tiny home that was built in 2015 that is for a sale for 14500 (or best offer). It is a micro tiny home that needs a few repairs such as the sky light and the plumbing. It is on wheels. Has a Murphy's bed. I've attached a link to YouTube of the company that made it. They have since gone out of business but the video shows the entire interior.

It can even be used as a shed. I own 3.4 acres of land and would be willing to keep the tiny home on the land for $500 a month or you can even buy it and live in it for $600 a month.
