Lon Welsh and his team over at First Alliance Title are the guru's when it comes to data. They came up with some interesting data. 

So what percentage of deals fall out of contract?  19%.  Interestingly, it doesn’t matter if it’s a cheap or expensive property or if it is spring or fall.  The numbers are remarkably consistent each month for the past two years that we looked at.  This is based on nearly 4,000 deals that we closed at First Alliance Title.

What does this mean to you? If you are a buyer, write backup offers! 19% of the time, you will get the property. If you are a seller, take a backup offer!
