I paid $76.71/sq ft for my house in Phoenix in February 2013. I'm in NJ now, and the house where I'm renting a room is valued at $177.47/sq ft.
Taxes are killer, though. $10,409 in NJ for this house (~3k sq ft home, 5001 sq ft lot, built in 1901). $748 for my AZ house (1825sq ft, 10,110 sq ft lot, built in 1976).
