No. A couple minutes with zillow.com or trulia.com will show you lots available for well under $10,000. Sure, they won't exactly be in premium locations, but with some work you can find some that are desirable & decent. I've seen some under $2000 just outside Atlanta, rural half-acre lots close to rivers & lakes.
The tech inside the house visually appears to be mobile home tech not self contained RV tech. So you'll need the $10K septic field, the $10K electric power line, maybe natgas/propane for heating/cooking, a $5K and up water well or $10K to connect to city water if available, it adds up.
(edited to add I forgot to add the cost of a foundation, in the south the freeze line is like 2 inches, but where I live I believe its 4-5 feet, so you're already spending 90% of the cost of a full basement, may as well finish it off and have a basement, but thats another $10K perhaps for something this small?)
TL;DR - buy/access a "plat book" for each county you're interested in, correlate each lot with a topographic map to identify interesting properties, visit the Assessor's Office to find the owners, write a polite but terse offer letter to the owners who live farthest away - good chance they don't want the property and will part with it fast for a reasonable offer. Yes, takes some work & money, but a whole lot less than list price.
