Its not the morality but the expectation of the housing prices bouncing back to normal like the rest of the economy that is keeping them from walking away.<p>But the issue with realestate is that its not as agile a market as stocks or commodities. the volatility observed in a month in the stock market is probably going to be observed in a year in real estate market. And I am not not even talking about the phase lag but the different scales of variation between the 2 types of markets.
