You know there is no need to respond by stooping to the level of the under-cutters. I had an unhidden map, that I priced as the highest and I actually even forgot about it. 2 weeks later is sold for 500K, when everyone was undercutting down to 250K or less. All it takes is some patience and just wait. If you got the guts and believe the stuff is priced too low, buy low and sell high. It is a flipping opportunity, you are doing yourself a disservice by trying to beat the undercutters in their game.
