We are considering something similar. Not a tiny home, but a cottage/park style. They are the 600 to 800 sq. ft. Homes, and cost about 60k. For NE Texas Piney Woods region, that's 4-8k for a less than acre lot within walk to the lake. Electrical and sewar/water less than 10k to set up. Property taxes some stupid amount like 13.00 yr. all told, that's less than I could get a 30 yr old run down house or condo where we currantly live. We're thinking of buying the land now and just running electric. And put a small used camper on it to use as a vacation place until we Fire. Than putting in sewar and dropping the house on it.
