But even if you don't have a garden or a spare room you can still earn money from penny pinching tourists by renting out your sofa!
That's right, you can pimp out your sofa for the night. The idea of couch surfing started in America by a site called couchsurfing.org and spawned a social phenomenon with over 4.16 million successful 'surfings' to date.
But while that particular site is all about meeting people and letting them crash on your sofa for free, www.rentasofa.com let's you earn money from couch surfers. In London a number of sofas are available 'for rent' and fetch around £20 a night.
If you really want to embrace making money from your sofa then you could even list it here on the gumtree website with other sofa letters.
So if you are strapped for cash and want to meet some interesting people then pimp that sofa. Let's be honest with the Olympics just around the corner demand is only set to increase as hotels become oversubscribed.
