Dear [NAME],
I wanted to write and let you know how much I appreciate you showing my listing at [PROPERTY ADDRESS] this week.
Please let me know if you or your clients have any questions or comments about the property, or if there's any additional information I can provide. You may also wish to take a look at the web presence I have created for this home at [WEB ADDRESS]. Feel free to call me at [PHONE] or write me at [EMAIL] with any questions or feedback.
I hope the showing went well, and I look forward to hearing from you soon.
Sincerely,
[NAME][TITLE]
