Can any agent do a short sale?
Absolutely not. Many agents have no interest in doing short sales because they require a tremendous amount of time and expertise, and if you do not know what you are doing, they often go to foreclosure and then the agent does not get paid. If an agent is not extremely experienced at doing short sales  then you may not want to use them.
 In every market, there are agents who specialize in short sales and have a team of staff members assembled to work on them, and then there are agents who are inexperienced at short sales and just recently started trying to do them, learning as they go, because they’ve realized they have no choice due to the state of current market.
You get one shot at doing a short sale – if your agent does not know what they are doing and has not learned the many tricks to the trade, you will likely find yourself being asked to sign a promissory note or worse, be denied by your lender or lenders and go to foreclosure.
In other words, let the inexperienced agents and/or attorneys learn the short sale process on someone else’s property – as the saying goes, don’t allow yourself to be one of the surgeon’s first patients.
