Funny you should say that. That's exactly what we are contemplating right now. Should we cash out in a falling market or should we wait until it recovers? I doubt the market will recover in several years. And we have yet to see the full extend of the mortgage meltdown and we will see how many banks and other investment institutions it will take down with it.

I should have sold about a year ago...

It sounds to me like we are onto something. It seems to me that your case is not unusual. As was drilled into my head, the plural of anecdote is not evidence. At the same time, patterns do emerge at times that are meaningful. Waiting to sell seems to be a well documented reaction to falling markets. By the way, this does not mean that waiting to sell is either right or wrong.

It's written by Case and Shiller. It's an oldie but goodie. Other papers on the website are worth reading to get an idea about housing bubbles.
