In the twin-city, Minesota, it's about the same. Even around big cities, like suburbs of Chicago,say, in Evanston, Deerfield, Skokie, you can get a mid-size house (2200 squre feet) for about 200,000. Just avoid those hot-shot places, like San Jose, Boston, and Connecticut. All these houses I am talking about are actually around heavily populated metro areas, the houses in those southern states (such as Alabama) are much cheaper.
So the average housing price for US is very likely to be 140000
