Are tiny homes feasible as rentals?

Since my daughter moved out, my home needs are greatly changed. I can’t afford to buy a house, but apartment living is absolutely not me. I have been looking into tiny homes, but from what I see, there isn’t much available. I see sales, lot rent, and vacation rentals.
This is a search I’m doing on nationwide availability.

There just aren’t many one bedroom homes standing anymore.
Is it cost, land availability, or something else which makes rentals unavailable?

If anyone knows first hand of tiny homes which are being used as long term rentals, please share that information.
