Real estate rollercoaster

Well, we found out that the people who we want to buy our house from rejected our offer and have decided not to sell right now for financial reasons.  So, what should we do now?  Last night, when Laurie came home, we drove around the neighborhood to look at what's on the market near us.  It would really be hard to move away from this area because East West Exchange is on our corner and thus I am able to go to the knitting group there and yoga without needed someone to drive me.  We'll see what happens...
