The answer is actually very simple. Trulia does not subscribe or cannot subscribe to any MLS or board data base therefore the listings are loaded from 3rd party websites such as Point 2NLS, #1 Expert, and a host of other realtor paid sites .
The most complete database of properties was always and will most likely remain Realtor.com and all of the other Agency websites . But then again if an agency does not participate in IDX than those won't be out there either.
