You missed the bigger reason the 3rd party sites will want to inlcude as many lisitngs as possible and will most likely include contingent properties. At the core, each and every 3rd party site is a lead generation tool. More listings = More leads = More Revenue…simple as that.

FWIW, I heard 2nd hand through a Sandicor Board Memeber that Realtor.com will still have them.
