The MLS contains all of the information about expireds, cancelleds and withdrawns. I am not sure how much of the MLS database is made available to third parties. For instance, the standard on line MLS providers like Realtor.com and those types receive active listings…Now someone like Zillow, I am not sure if they receive sold listings from the MLS or if they compile it from the county.
As a Realtor, (joining SDAR and paying dues) access to the MLS is one of the benefits. Since the MLS is really a private database, I do not believe the information is public domain.
Now I would assume Dataquick purchases MLS data to compile all of thier stats as well. Again, whether they purchase all of the other categories besides actives, pendings, solds is speculative. Maybe they do but they decide not to publicize it?
