MLS's can update the data feeds they send to Trulia at any time, and we process these updates every night. However, we receive listing information from many other sources as well.
To ensure that our data is accurate and up-to-date, we ask that you alert us when you do encounter listings for sale that have already been sold. You can do this by using the "Report an Error" feature on every property page: http://i.imgur.com/1xZ5V.png
I hope that helps to answer your question. If there's anything else I can do for you, don't hesitate to reach out.

The metropolitan MLS system or "MRIS" has a consumer site available for home buyers called
LISTING BOOK which is owned by the MRIS system. The Listing Book website is refreshed every 90
seconds for accurate housing availablility and also gives you more individual information on each home.
Email me your email address and I will set you up with a FREE... Listing Book account.

Lots of lag on the websites. Be happy to set you up with the best site there is, and you can search in realtime like agents do.
Give me a call or drop me an email, and I'll get you going.
I can also set you up for my daily search for all my buyers, done by a real person. If you are searching, and we are searching, all the better!
I'm right here in Frederick and work everyday in the area market. Look forward to hearing from you and to helping you.
