More and more MLS's require vendors like us to pay Data Access Fees that are passed through to the customer (you). These vary from $0/month up to $33/month. If we don't have to charge a pass-through fee, we don't. For your MLS, you can check their pass-thru fee on their information page by visiting https://showcaseidx.com/mls-coverage/. Although the rates may vary slightly, 99% of IDX companies charge these fees.
