Walmart sells this tiny house for less than $16,000

Shipping is free, and the house will show up at your address on a flatbed truck.

When you’re buying laundry detergent or toilet paper at Walmart.com, you can also buy a tiny house.

One option, a 19-by-20-foot “expandable prefab house,” comes with a steel frame structure that unfolds from the size of a shipping container to create a basic studio cottage with built-in windows, insulated walls, and an insulated roof. Inside, there’s space for a bedroom, living room, kitchen, dining room, and bathroom. The bathroom comes with a toilet and shower; the rest of the space is unfinished. The cost: $15,900.
