It misses the biggest advantage of the Tiny House housing sector.
The best tiny houses are really very upscale mobile dwellings. You can get a log cabin built on a trailer that is insulated and durable like standard housing, but which can be moved across the country to follow the job market.
If you work on pipelines, you can move your house from Texas to South Dakota for the or four years, then to where the jobs are after that. But the house has to meet highway standards so one story plus a loft is about it.
Or you could just go old-school and purchase a fifth-wheel travel trailer: more room, less stairs, already comes with kitchen and bathroom of its own.
It’s cheaper to buy an RV or travel trailer.
