Supplemental listings are properties you wish to include on your website but which are not listed in your MLS. To add a Supplemental listing to your account click Listings, then Supplemental in the submenu, and click Create New in the upper-right corner.
Here, you will see a form you can use to enter in details about your listing. To begin, choose options in both the Select MLS and Select Property Type fields. Once these options are chosen, fill out any other information about the listing.
NOTE: Adding photos is done in the next step after the fields are saved.
Your new supplemental listing will show up under Listings -> Supplemental. From here you can add photos, open houses, and virtual tours to each listing. You can manage supplemental listings the same way you manage Active listings. Please see this article for more information on managing listings including adding photos, etc.

You can now display your Supplemental Listings on either your Supplemental Listings page or Featured Properties page in your IDX Page Links.
Note: Adding a property under Supplemental Listings in IDX does not submit it to the Multiple Listing Service.
