Host people

Software: Airbnb

Service: Host people in your spare room, sleep out or house. You keep the place clean (though you can hire cleaners), welcome guests and help them find nice spots in your area (no need to cook or provide food). Airbnb handles the website and payments while you focus on being a good host.

Income: You earn a big percentage of what guests pay per night. Airbnb takes a small cut.
