Let me know what you think of this idea...

There are lots of people who love to travel and want to go travel, but it can be very expensive. But what if you could rent your home out while you are gone so you don't have to pay for a vacation and the price of your house sitting idle. This could even be done like a house swap where person X wants to vacation where person Y lives, and person Y wants to vacation where person X lives. So instead of paying for an expensive hotel or renting an expensive summer house, person X pays the cost of living in person Y's home (electricity, monthly payments on house) and person Y pays the cost of living in person X's home, for either a week, month, or longer. Therefore people can travel to many more places for longer and for less money.
