Real Estate - The Real Estate feature is a great tool for real estate agents to showcase properties they're renting or selling. Import listings via a CSV file, IDX API account integration, or manually. IDX is a type of data feed provided with your MLS membership. In some cases, MLS may require you to pay for access to this data feed. IDX typically (but not always) mirrors the data available on your MLS site. If your MLS provides access to this data feed, you may use that access to promote ALL listings on your website, not just your featured listings.
