People who rent out property on sites such as airbnb make more money than traditional landlords whose tenants stay much longer. One San Fransisco resident claims he makes $500,000 each year from 14 homes he leases out by night. Those who rent out their homes for a night price lure in tenants by offering better deals than what hotels can afford to offer. If a hotel charges $250 a night, they'll ask for $150 or less. Sounds like a good way to make money if you live in a place where hotels are very expensive.
