Depreciating? I built an 8 x 20' tiny home to code. No inspection fees or building permits required. With solar panels, battery bank, awnings, front porch, gas heating, full bathroom with shower, a clothes washer in addition to a full kitchen and library. Fully insured, it's current value ($46k) continues to rise well above the cost to build it ($24k). Not bad for 140 sq ft of warm, safe, and fully owned interior living space.
