Very common if you want to live in domicile. It works well because you get more "living space" than you pay for.... some of your roomies are always on a trip.

The problem living with non-pilots, is they expect you to pay your full share of utilities even though you're gone half the time. I actually bailed on an arrangement like that where the house had a cleaning and garbage rotation...I was gone for three weeks, and came back to find that my roomies had saved up the cleaning and trash for me since I missed my duty week. Of course I wasn't even there to contribute to the mess. I moved out immediately, without doing any cleaning
