When looking into doing a Short Sale the biggest mistake a Seller can make is not Listing their property with an Agent who is highly educated and Certified in Short Sales.  Make sure the Agent has an CSP Designation.  Too many Agents are Advertising themselves as Short Sale Experts who are not.  There are key aspects to being successful in Listing and Selling Short Sale Property.  Agents who know what they are doing, who are trained and certified have a higher success rate in closing a transaction than those who do not.
