I agree SDR, if you can absorb the additional 10% cut on asking price and subsequent negotiation cut, odds are your in good enough shape to weather the store to make transaction costs outway the benefit of doing it.
If you bought 2005 you probably can’t absorb the cut and get out without a loss. In 2004, you may be breaking even. If back in 2003, well, free taxes helps, but housing has a ways to go to make it worth that kind of reset.
