what is idx in real estate

IDX, or Internet Data Exchange, is a system and software used by real estate professionals to display MLS (Multiple Listing Service) listings on their websites. It establishes a data connection between the MLS database and the real estate agents or brokers website, allowing them to integrate and display property listings. IDX was created to enable real estate agents and brokers to share each others listings, level the playing field for smaller brokers, and standardize property listings across the board. It is a policy established by the National Association of REALTORS®, under which brokers exchange permission to display one anothers listings on the internet. IDX is crucial for real estate professionals as it allows them to provide comprehensive and up-to-date property listing data on their websites, thereby aiding in generating and retaining leads. Additionally, IDX is only available for members of real estate board MLS® Systems for display on their websites, and licensing is required by MLS® Systems for its use.
