IDX is a system where brokers give each other permission to display their listings on each other’s websites, mobile apps and audio devices. Brokers who participate in the program can display all of each others active listings. If you choose not to participate, no other broker will be permitted to display your listings. You may include your listings in the Broker Reciprocity database without having your own web site.


Frame the MLS search to your website with no programming required on your end. Listings display in real-time and include up-to-the-minute changes. Your private listings are included. The Custom IDX Search feature allows you to display listings in the areas of your expertise.
