Dear Leonard,

Just a Quick note to thank you for a job well done.

Both Betty and I appreciate very much your pleasant and professional attention to the sale of our townhouse. Our experience with some of your competitors left much to be desired, but once we placed our home for sale with you, things began to happen.

Thanks again, and our every wish for your continued success.
