But my gross vacation rents are 5x what my rents would be with an annual tenant....making these costs tiny in comparison with the increase in rents. 

SupplyLas Vegas is unique in that it is a tiny island of privately owned land in an ocean of federal land.

@Bob Norton This one will rent at around $1,200/mo, maybe a tiny bit more.

An alternative is to buy cheaper land and put 2 tiny homes on it with 20% down on each.

Much more desirable for working professionals than a tiny extra bedroom. 

Unfortunately you're a little late to get in on it, but Duluth did break ground on a tiny house development project in the summer of 2021 that awarded free lots to contractors to build the structures on and they might do it again in the future, so might be something to watch out for.If you're looking outside of the city and up the shore where most of the tourism occurs, you might be able to find something more "affordable".

You can't build tiny homes around where I live.

Tiny markets are probably hardest to know.

When I bought a fire damaged house on Cape Cod to live in, and remodeled it, we decided to not replace the drywall in one bedroom that had just a tiny bit of smoke smudge on the walls. 

Mainly looking at a unique experience, it will include tiny homes, domes, and an area to park RV's.
