Welcome to the site!
Many of the yurts you are looking at, while considered temporary in many places, are structures that can last quite some time. To build a yurt you describe would probably cost between $25,000 - $30,000. You are going to have to build some sort of platform, and if you are going to reside in it, the town is probably going to want you to upgrade the
. Wiring, gas and septic would have to be to code.
Now with this being said, you could re-sell most of this away after 1 year and recover a good portion of your money providing it is in good condition.
I would definitely check with the town/city to see if they have approved yurts in the past, and if so, which manufacturer did they approve. It will save you some $$ I would think.
Honestly though, if you are just looking for a structure to live in for a year and then be done with it, then I would just get a second hand trailer while you build. Much cheaper and everything is in it. In fact, I do believe you can lease them.
