Welcome to Trulia Voices and thank you for your question.
Only those listings that have been submitted to Trulia manually can be edited at this time. All other listings should be updated with the source, which in your case is your MLS and Listhub.net. Please contact your MLS and/or Listhub.net to ensure that they have the most up-to-date prices for your listings on their site and in the data feed they send to us. Once Listhub updates their data feed, our display should update automatically with the new information.
Please be sure to let us know if you have any additional questions or feedback about this.
