Here in South Florida, one of the epicenters of the RE bubble, prices are down anywhere from 20-40% from the peak so far. My own townhouse (currently for sale) is down about 15% so far, but many others are already much worse. I just found a 3/2 REO going for less than 50% of its current FMV, which is 20% below where it was at the peak. :shock:
Realtors I've spoken with here said we're seeing approximately a 2% per month steady decline. I'd expect a 50% total haircut on a lot of stuff down here by the time it's all said and done. My guess is it'll take another 1-2 years for the bottom to be reached, and I don't think it'll bounce right back up quickly thereafter, it'll probably flatline for another year or two.
If we get back to historical averages of appreciation, it would mean it would take another decade or longer to get back to where prices were at their peak, and some might not get back there for far longer than that, since their bubble prices were so out of whack to begin with.
