House Swap

See how they do it in Cuba. Yes, the government owns their housing, but, they don't have mortgages. It might sound like madness to us, but i think it's a very creative barter system to trade houses instead of buying them. One may not always get what they want, but how many of us feel completely satisfied with our own housing situation in our current system? In the future, we might have to take some cues from Cuba's house trading system when building materials in the U.S. might become unavailable and there are a glut of houses already in existence.
