I don't know if it's true or not, but I've heard that Muslims won't sell their property to non-Muslims. There is a nice little house in Denison, Tx that is owned by a Muslim. He doesn't live there and I'm told that he won't sell to anybody but another Muslim. The house is vacant, the yard unkempt, and the empty house is nothing but a detriment to the owner and the neighborhood. I don't see why the Christian Community should reciprocate if this IS true.
