In reply to SKJSS (formerly Klayfish) :
Have you considered a really nice RV?
I own 2, and rent them for "glamping" on AirBnB and VRBO. They're in a really nice location (I rent the lots).
My units are lightly used, in like-new condition. One is a 2020, one is a 2021. I bought them for about half the price of new units, and it was well under 10% of the purchase price of small vacation properties. My rents are about 75% of the rents of small vacation properties.
I charge a premium, and get good guests. The buy-in was pretty low, and if I decide I don't like where they are parked I can relocate them easily.
The only trick was hiring a cleaning person I could train in the specifics of RVs.
I'd happily live in one.
