Buying a house in this economy? Actually, it might not be a terrible idea if you go the flat-pack route found with many of the tiny houses all over Amazon - and thus, avoiding too many lumber tariffs; it could cost you a fraction of the average house price in the U.S. (which is just over $350,000, according to Zillow). Case in point: this two-story container house is listed at Amazon for under $50,000, less than a quarter of the current median home price.
