It's Still On

We finally heard back from the Estate Agent yesterday. Our buyer is still going ahead with the sale, provided that a SOLD sign goes up. She was apparently confused when she didn't see one, and assumed that we hadn't accepted the sale or something.
I'm finding the intermediary of an Estate Agent actually rather unhelpful. We keep talking to different people, and getting a different story from each of them. Of course, it is the same for our buyer. We briefed one person to reassure them that we were not looking for a higher offer etc., and then our buyer ended up speaking to another person who didn't seem to pass any of that on.
We are going to write our buyers a letter to cut out the middle woman, and make sure that they get the message that we are not the type of people who would accept a higher offer once we had proceeded with a sale. Then we will just see how it goes. I will be so glad when this is all over.
