Setback

We had some bad news today. The people that were going to buy our townhouse pulled the contract because the husband's new job for which they were relocating lost its funding, and therefore they are apparently staying in California. Hopefully this is just a minor and temporary setback. But, it puts a few unknowns back into the equation. Will we get a new offer quickly enough to be able to close by the time the new house is ready? Will the next offer be for less money than the first? Will the next offer we accept even make it through to closing or die beforehand like the first one? Stay tuned...
