One consideration in choosing a tiny home is function. Currently we're renting a smaller three bedroom, because it's in a safe area, good rent, and was recently redone. It allows us to have people over, something we value. If we just needed space for ourselves, a one bedroom, one bath, would work. Another is how attached you are to your stuff. Maybe this will change, but I love my grandparents bedroom set, the big overstuffed antique sofa we salvaged, and our 1930's china hutch. None of those work in a much smaller space. Build ins would make better sense.
