@Kandi Sterling yes, you are correct about why larger properties book out further in advance. That is not requirement for profitability but I certainly sleep better at night.
I do agree that smaller units can be a better ROI than 2- and 3- bedroom properties, especially since there is so much overlap in the guest avatars between those bedroom counts. I personally don't like 3 bedrooms because the nightly rate to be profitable is too expensive to compete with hotels and 1- and 2- bedrooms, but not enough space for larger groups. That said, I don't think I could've acquired 2 smaller properties for the price of my 5 bedroom that also outperformed it.
As for your tiny home photo, I'm simply not a fan of that design. I don't doubt the practicality and workmanship, however the design doesn't do it for me. I think tiny homes are constrained by the dimensional requirements to be street legal without a state trooper escort. I've seen some great designs in the container or mini-MCM realm, however a lot of those have square footage that is closer to a small house than a true tiny home.
To each their own- I hope you have success.
