Could you live in a house the size of perhaps a garden shed or a 1-car garage? Well, tiny houses seem to be a growing trend in America. From college grads to retirees, Americans are downsizing and trading space for simplicity. Tiny houses are often paid in full at the time of sale and have the flexibility of being moved from one site to another. No mortgage payments, no permanent address, fewer house chores--it's lifestyle change that can work well for just right type of individuals.
