"Julie,
Thank you for all of the extra attention that you gave 
Toni and me in search of our dream home. I am extremely satisfied with your performance.
You handled adversity due to unforeseen circumstances as well as any professional could have done, which is my admiration for excellence in your profession. You were able to sell our old home in two weeks of listing, spend your time driving Toni and me around looking for a new home, and calm our nerves when our patience was running low. Others we talked to commented how courteous and pleasant you were at all times. These complements are only the beginning of our appreciation for you. I would like to volunteer that you have our permission to use us as referrals."
