If you are buying, I would suggest you need to ask the agent, "Do you show short sales?"
Many agents still tell me they won't show "short sales" to buyers, so hence the reason I put the above.
Remember not all short sales are "short" in Time Frame...some may close in 2 months, but..many can take months to close, so hopefully you are prepared to wait.
Don't hesitate to contact me.

Interview and ask the agents if they have successfully closed short sale transactions. Ask them to explain the process to you. You should be able to get a good feeling about an agent's knowledge of short sales after some discussion.
Best of luck!
