Dear Margi,

Thanks for your call letting me know about the completion of the sale. I would like to thank you and your team for their efforts. Karen did a fantastic job in your absence, I hope you had a good holiday. 

 I really valued the supportive and practical approach. You both understood that there are emotions involved in these enterprises and that came through.

 I found you both very easy and professional to deal with. I would have no hesitation in recommending your company for the reasons I've already stated.

 Thank you again and very best wishes
