In 2003, my entire graduate class (I think it was accounting 4) and the professor all had a laugh at me, as I tried to explain my belief that there wasn't enough demand for these new homes that everyone was putting their retirement $ into.
i tried to explain that the adjustable rate would be too high - they said the dollar is just getting stronger thanks to 9/11, and that paying higher mortgages wouldn't hurt people.
I tried to explain the population here was flat, and if a recession did hit, as does following wars, then our services/tourism/construciton industries would go belly-up, and they'd move - we'd have thousands of houses sitting empty.
Most everyone in the class owned a home, many were mortgaging it to pay for a 2nd or 3rd.
Today, many of them are in some serious shit.
