Seriously, if San Diego homes loose 80% of their value from the peak over the next 5 yrs….that would mean the economy has been completely destroyed by then and we are in a severe depression. Frankly, home prices would be least of my concern by then when I am standing in soup line with my kid and wife (I assuming we both would have lost our jobs by than).
Its great that you got your calls right till now, but don’t get carried away by negativity. I would advise you read Rick’s analysis on inflation and how the Fed can create significant inflation eventually if they keep the printing presses on.

Will quality of life degrade for average american over the next couple of decades? probably yes. But, it will actually happen in the form of inflation as an additional form of taxation, where we will be spending a higher percantage of our disposable income on basic necessities of life like food, housing and clothing, like the rest of the world already does.
