The ink has long since dried on the purchase and sale agreement for that seaside inn you have always dreamed of owning, but the seller has backed out at the last minute without explanation and failed to attend the closing. You suspect that another buyer has offered a higher price and the seller will try to close on that better deal post haste. You've done your due diligence - you know the inn is profitable and is exactly what you have been looking for. You want this property, and you want it for the price you have agreed to pay. How can you protect yourself from losing this special opportunity to the third party buyer waiting in the wings - whose identity you don't know?
