An agent does not need to be earned in as a Luxury agent by their Market Center in order for their qualifying listings to sync to the syndication sites. You can find more information on the earn-in process here (agent side of the process) and here (leadership side of the process)
Each Market Center will have a minimum price point set that a listing would need to meet to be designated as Luxury. This also determines whether a listing qualifies to appear on KWLuxuryhomes.com.
Market Center Leadership can view these minimum price points, for each county, in the CommandMC Administration Applet, and is set by the Regional Leadership team, based on the local market and various other factors.
It is no longer necessary to designate a listing as Luxury in Command > Listings. A listing will automatically be designated as such based on the price and the guidelines above.
