“I am writing to express my appreciation for your assistance in the sale of my cooperative apartment. You helped me find a buyer promptly, and you and John were always responsive to any request.
I also greatly appreciated the fact that you and John went to my apartment the night before the closing and found small personal items that were very important to me. And, finally, your calmness on the morning of the closing and your assistance with the last remaining, annoying issues was greatly appreciated.”
