You may look for willing landowners, farms, RV parks, tiny home villages, or consider purchasing real estate. Real estate often might involve running new utilities to the property in order to accommodate the tiny home, if they are legal. Sometimes they are considered as ADU’s, or accessory dwelling units on properties that already have housing on them.
Some suggestions:
Backyards where RVs or sheds are allowed
Renting your own piece of land
RV parks
