I answered "no" and I don't mind getting rather specific.
I bought in Ormewood Park in '04, and I've paid that mortgage down to close to $200K, and I'm reasonably sure I could get close to what I paid for it back in 2004 if I put it back on the market (upper 2's). I was unsuccessful in trying to sell it in late '06 early '07 because I think the agent had it listed far too high (upper 3's dropping to lower 3's by the time I pulled it off the market. The renovated house across the street sold in the lower 3's last year.
In East Atlanta, I purchased in foreclosure at the height of the real estate boom, just before the crash, in the summer of '07, but since it was a foreclosure I still think I got a good deal on it, even in the face of the crash. I've paid that mortgage down to close to 300K, and I'm reasonably sure I could sell for far more than that today, even in the midst of the crash, especially with all the improvements we've made on the house.
So, I don't think I'm under water on either one, right now. Now, if home values continue to drop, either or both could turn into an under water situation, but if values go that low I'll just throw in the towel.
