Arm yoursellf with information yourself from the multitudes of real estate sites both local and national. Then based on what you know- similar homes sold, similar homes for sale currently and for what price- "how to sell distressed property" info. With that information sit down with your agent and if possible their principal broker and voice your concerns regarding their marketing and action steps. you can not just throw a distressed property up on the multiple listing service and hope for the best.
They may be doing alot that you are not aware of, but you wont know if you dont ask. If your agent is new to this type of sale ask that the principal broker assist.
Last resort is that you do have a legal right to cancel your listing with that company and resign with someone who markets themselves as a specialist in distressed property, but be sure you are not comitting to pay a commission to the current company AND the new company before you make that decision.
