Candace is exactly right. And very often the seller may qualify for a loan modification and doesn't need a short sale. Our office has some seven or eight documents and disclaimers that must be filled out and followed to a "T" before moving forward with a short sale. And, MARS spells it out perfectly. Good resource.
Call your State Realtor's Association. Here is a website I googled which explains your fiduciary duties as far as advising on shorts. http://homesolutioncounselors.com/ftcs-mars-rule-short-sales
There are many more. Unless you say to a client, you have now knowledge of shorts, then once you are giving advice you are participating in some way of negotiating.
If you are planning on working with short sales, I strongly suggest the CDPE or CDRS course. It really is a must have if you want to work with short sales.
