An out of town client
Thank you for being so understanding John.  You are a very patient realtor indeed.  We haven't worked with many before, particulalry any that are out of town like you are, and I don't think our local realtor was as responsive as you are.
 
Thank you again, we really, really appreciate your efforts.

I want to express my gratitude to you for all you have done in the past 3 weeks to get our home sold.  You have truly been up front with us, very professional and we were very fortunate to have you present our home.  You will be highly recommended for the expert job you did.
Thank you again,

Diane
