Jobs,jobs, and or income! It’s all about affordability. When I first clicked on the link I thought he knew what he was talking about, then I read more and decided to skim the rest. In general I do agree with him, just not with his logic. It was interesting to see that the country as a whole has not gone insane, there are actually places where home prices are dropping. If I take my total monthly mortgage and divide it by total yearly household income, I get 1.17%, which in my opinion is affordable. If that percentage gets above 3% then I would say there could be trouble, 4-5% and you should seriously be thinking about if you are paying too much to keep a roof over your head.
