I"m afraid that Tim is actually incorrect. Trulia does receive listings directly from many MLS systems at this time. You can inquire directly with your MLS as to whether or not they send listings to us, or you can send an email to our Customer Service team via the link below.
If you opted in to the listing syndication with Point 2 Technologies through our Association, your listings will feed from our MLS to Point 2, then to Trulia. It usually takes at least 48hrs. If there is a propblem, you will need to contact Point 2. There are other vendors out there that assist in syndication as well.
