You already have two great answers to your question and I agree completely. Best of bold worlds for you. I just had a disturbing item show up on a title search - a $23,000 lien on the person buying my listing and we're scheduled to close on Friday. Would you know how to handle that or any other issues that could arise?
The experienced agent will know how to get over the humps that almost always arise between acceptance of an offer and closing.
Best of luck to you.
