Beginning today, November 10th, you will be able to display multiple, MLS-provided map overlays at the same time.
When editing a Map Search or on the Map tab, open the Overlays menu and click to select each MLS overlay you would like to display. As shown in the example below, each overlay you select will have a check mark next to it and multiple overlays can display simultaneously.
If you want to stop displaying an overlay on the map, open the Overlays menu and click to uncheck the overlay.
Please Note: The ability to choose multiple overlays only applies to MLS overlays; overlays in the My Map Overlays section are still limited to displaying one overlay at a time.
