It sounds to me as though you are a seller without professional representation. By electing to work with your attorney, your attorney is the ONLY one who can and should provide you with advice.
We don't know any of the details of the transaction.
I find it incredible that you would post questions like you have to a public forum. We all may Look Good and Sound Good, but in truth we have no idea of the complete situation and I for one would be very skeptical about taking any advice from any of us in your situation.
This probably will be not win me any bonus points on Trulia, but sometimes we can do more harm than good by offering advice, which may be good advice....but for the fact that we do not know your situation. So it could happen that you take some poster's advice, apply it, then you are worse off because it caused MORE problems.
The ONLY advice I would give you is to get some competent advice from a Realtor that knows three things:
Your personal situation (when you need to close, how much you need to net), your property, and the local market values and conditions.
My last word is that Realtors would not be around for over 100 years IF we did not add value to real estate transactions. I strongly advise you to stop blaming the buyer's agent. His only duty is to his buyer. Your challenge is that you do not have a Realtor representing you.
