Then how do you explain the fact that KJ, an AP with no other source of income, qualified for and got a purchase money loan for a house in Las Vegas?

Las Vegas has a long history of contrarian banking, e.g. E. Parry Thomas loaning millions to mobsters running Las Vegas casinos when no other bank would touch them.
