Welcome to Trulia Voices and thank you for your question. Your listings are being provided to us directly by two sources: Century 21 and your Superlative website. If you click on the links to 'View more details' that you find on your property detail pages, you'll see which site is the source for each listing.
In order to update your listings you will want to contact Century 21 or Superlative accordingly to ensure that your listings are updated on these sites and in the respective data feeds that these sources provide to us. Once they update the data feeds they send to us, our display should update automatically thereafter with the new information.
Please let us know if you have any additional questions or feedback for us.
Welcome to Trulia.
Difficult to answer your question not having more details. May be your MLS syndicates to Trulia or it is syndicated from another source you are using to post your listings...If a listing is syndicated to Trulia, you would have to edit the source and within 48 hours the change will reflect on Trulia.
