Depends on your location, because I live near the world's largest medical center, only a few minutes from tourist attractions, as well as the NRG Stadium (where the Superbowl was this year), I have been booked almost every day since starting Airbnb. I make about $1300-$1400/mo from the space at $50/night and pay $975 a month in rent&bills so I come out with about $300-400 a month in profits. Superbowl was particularly profitable, I made $1200/3days so I have some leeway for future losses if they arise. It's profitable and convenient if you have an easy alternative place to live close by.
