If you live in Phoenix and own a rental. You might be renting out to one of my good hispanic friends that seem to have 30 people in a 3bd house. My friend I call Mexican Joe lived in a 2/1 while we were growing up(neighbors). He lived with his 3 brothers, mom, dad, aunt, uncle and their 2 kids. They also had a 1 bd back house where after the cops busted the coyotes that were living there, a few of Joe's family from Mexico shacked up there, I remember at one point there were 6 people living in that little shack.
They were all great people, are still close family friends today and I attend every party they throw(trust me, you would too) the landlord has never complained and the house has always been immaculate and landscaping the best of the neighborhood.
but of course, that is a isolated situation. I would never buy a rental property with that many people living in it previously(Unless it was Joe and his familia, although Joe has sinced married and moved 2 streets over) or allow that many people to live it one now. I think we have actually have a 2 persons per bedroom rule around here.
