Niki from Trulia here. Your listing at 3500 Serene Hills Dr has been claimed to the active listings in your profile and you are showing as the listing agent in the property details.
Per our terms and conditions for listing, if you are a real estate professional, you agree that you will not claim or submit listings that do not belong to you. When a listing is sent in to us there is a "listing agent email" field in the data. We match the email address in the data to the email in an agents profile. When you "claim" a listing our system automatically sends an email to the address in the listing data for permission. This is also the case if the property has been claimed to another agent.
Thank you for using Trulia for all of your real estate needs, please feel free to contact us directly if you have any other questions at firstname.lastname@example.org or by calling 1-888-466-3501.
