Why agents care
Most agent websites run on an IDX product, so knowing whether yours allows custom HTML or iframes on property pages determines how you add calculators.
Glossary term
IDX
IDX (Internet Data Exchange) lets participating brokers display other brokers' MLS listings on their websites under MLS rules. IDX vendors provide the search, listing pages and lead registration features many agent websites use. What you can add to IDX pages, such as custom HTML, depends on the vendor.
Example
Example: an agent's IDX template allows a custom HTML block below the property description, so a payment calculator is pasted there with the list price as default.
Questions by topic
IDX: common questions
Can I add a calculator to my IDX listing pages?
If your vendor allows custom HTML, scripts or iframes there. Check settings or ask support.
Is IDX the same as MLS?
No. The MLS is the database. IDX is the framework for displaying its listings on websites.
