In Canada, as a poor student/underemployed person, I lived in mansions with 6-10 friends. Those things are •very• hard to rent out. The neighbors hated us though ( we were young, drove crappy cars, sometimes had loud parties, and just generally made a mockery of the rich neighborhood we lived in. The absentee landlords were just parking there money in property, so were quite happy with us.
Things might be different in the States or elsewhere.
