You will not be buying the "Market"; you will buy one house. I presume you will be living in it, so things like the floor plan, the quality, the accessories, the yard and the neighborhood will be important. The big question is; is the price you pay, more important that these things. If the price is the only thing that matters, then I expect you to be living in a 2/2 by the railroad in a high crime area that stinks.
As another consideration: You will proitively know where the absolute bottom of the Market occurs: You be able to see it clearly a year or two later, looking back! There will be no announcements, no headlines in the newspaper or on TV, there will be no Bell Ringer on a street corner. There never has been, and there never will be. If you choose to believe that it will happen in two years, for you, that will be correct; It will.
