"I'm writing to send you my very, very grateful thanks. You've been absolutely amazing and I really appreciate all your hard work, patience, kindness and support over the past few months. You have helped to make a complicated and frankly slightly scary process so much simpler and easier. I really appreciate the fact that you have always taken the time to explain everything to me and have been so patient with all my questions. I'm also really grateful for how fast and competently you got everything sorted. I know that the fact that I am already in the house now has everything to do with you moving things forward so fast and keeping on everybody's case."
