Wouldn't it be roomier and cheaper to live in a mobile home?
I'm not getting it.
It would be, most likely, cheaper to just buy a mobile home. However, many places put a ban on them, unless you put it in a mobile home park. They're banned in my county, for example, and most of the counties that are near Washington DC. I think lot rents usually run around $600-800 per month, and then you have the cost of the mobile home on top of that.
However, I'm sure there are going to be even more bans and restrictions on these "tiny homes". In many cases, they're just homes on wheels, which is a fancy way of saying a trailer.
One advantage, however, is that you could probably just take one of these tiny homes and park and level it pretty easily, whereas a mobile home would take up more space, and might require more effort to level.
Mobile homes aren't designed to be moved around a lot. Usually, just from the point of manufacture to the trailer park. The more you move them, the more likely they are to start falling apart. But, you never know, those tiny homes might have that same problem.
