I have been watching a series about people building tiny homes on flat bed trailers. They range from 200 to 400 square feet of living space. All living areas are very compact and tight, but they have living rooms, kitchens, baths, and bedrooms. They utilize lofts for extra space for an office or extra sleeping, and they even have outside fold out features for outside living areas. Many put solar panels on the roof to cut energy costs, and composting toilets, but best of all you can move the home anywhere you can drive to. I like the thought of not having to pay property taxes. Even insurance would cheaper because it would be RV insurance instead of a costly home owner's policy. I don't think I would like apartment living, especially as a single senior. I was going to sell my place and move close to my brother, but then he started talking about living with his son, and I realized that if that happened I'd be stuck somewhere where I'd be alone and away from anyone I knew. But with a tiny house on wheels, I could go from one family member to another if I needed or just wanted to visit family members that are in other states. The cost range from $30K to $90K, depending on just how fancy you wish to go. It would mean paring down to bare essentials, but I like simplicity.
