i disagree with your statement many jews would love to buy a house in arab towns  however an arab who sells his place to a jew would be killed in the center of town allready happened a number of times thats why we have the current ridiculous situation in hebron where jews bought a house but the guy who sold it tells the media that he didnt sell it as for the number of people per room mentioned under this comment its only a matter of children per family and customs  an arab person having  children might be just as rich as a jewish person whos got  children hell also have more rooms than the jewish guy has since construction is cheeper for arabs so who is richer i dont think that the people per room is much of an indication
