in an incredibly tough sales market, you made this happen

Thank you so much for helping me sell my house. During the year that we worked together, I was impressed and delighted by your knowledge of the market, your attention to detail, and how well you followed through on everything! Even in an incredibly tough sales market, you made this happen. I would be glad to serve as a reference for you at anytime. Again, my thanks to you for making this sale come true!
