If you're working with persons involved in a short sale there are a few things that go beyond typical agent advice.
Some of them have to do with financial and legal matters.
For these areas I advise my clients to seek competent legal and financial professionals.
Should they receive creditor calls, I make sure they sign a cease and desist letter that allows them to refer matters of the short sale to the listing agent.
I also provide a link to the government's Fair Debt Collections Practices Act pdf.
This gives them a good reference point for their rights.
There are plenty of resources out there that will assist in matters ouside the scope of the real estate agent.

You are giving excellent advice here, Chuck. We cannot stress how important it is that clients and/or prospects go directly to the source for expert answers to their questions. I handle short sales in Camarillo, CA and always recommend several third party professionals to assist in providing consumer information.
