6. Do open house comments appear on Zillow?

Yes, they normally do unless the MLS and Zillow have made other arrangements. 

7. What external sites receive MLS data?

Brokers under the MLS will define what third party websites receive these listings. Usually, these external parties include the following:

  • Zillow
  • Trulia
  • Redfin

  • realtors.com

8. How many photos can be uploaded?

10. To be in compliance with IDX, must an MLS provide both a downloadable data feed and frameable web site capability or just one or the other?

Generally, IDX does not require MLS to provide a website for public display of listings but NAR obliges MLS to provide downloadable listings if requested by a subscriber.

11. Does IDX conflict with the real estate licensing law or the NAR Code of Ethics?

According to the Bridge MLS Website: “Implementation of IDX is not inconsistent with state law. NAR’s IDX policy statement is consistent with the Code of Ethics since no display of other Participants’ listings can occur without their consent, and consent is assumed unless affirmatively withheld by the listing Participant.”

12. Can MLS charge a fee for downloading listing information to participants and subscribers?

The answer is yes. NAR’s policies do not limit associations or MLS from charging their members. The range of fees can be decided based on how much it costs to maintain MLS services. 

13. Can all MLS members participate in IDX?

MLS has the freedom to include agents or brokers within a dedicated framework. 

14. Can I authorize other members to display my listings under IDX or the other way around?

You can choose to display yours or others’ listings but you should seek their approval. In case you prohibit someone’s listings to be displayed, you cannot display theirs either.  

15. Can sellers “opt-out” of displaying their property listings on IDX?


16. Can the MLS refuse my listings if I do not permit other participants to display them on their web sites?

No. There are no obligations to consent for displaying other participant’s listings.

17. What listing statuses are included in IDX?

Pending and sold are official IDX statuses. MLS might include others like withdraw, canceled, expired or etc. 

18. What if I don’t want to display sold listings?

Brokerages may choose to show or not to show these statuses because they are entitled to it, but not limited to. They often do this for marketing purposes. 

19. Does IDX include confidential information that is available to the public?

This is a tricky question. NAR’s requirement is that information intended for other realtors cannot be shared with the public. However, since this is not a mandate, local MLS can remove this requirement. 

20. Does the MLS have to be listed as the source of the data and how often does the data have to be updated? 

Yes and yes. The source of these data is the MLS and generally the data must be refreshed every 12 hours.

21. Why should we allow our listings to be displayed by competitors?

This is a mutual decision by all realtors which helps to provide better service for clients and the whole industry as a whole.  

22. What can I put in the public remarks?

These are public information that affects the tenants or describes the property.

23. Can I load a listing for comparison purposes only?

Contact your MLS and check if it is  possible.

24. Which lockbox is okay to use?

MLS use a variety of lockboxes or combinations of them. Consult with your MLS or brokerage to make a decision. 

25. Do I have to upload a photo to my listings even though it is pending?

Yes, you must upload a photo of the exterior of the building in 3 days unless the seller opts out. 

26. Can I advertise another Broker’s listings on Craigslist or Facebook?

It is against the regulations to do so unless you have a written permission from them.

27. How long do I have to mark a listing sold on the MLS?

You should mark a sold property in less than 1 day from the escrow. Otherwise, you are violating terms.

28. I have a secretary that will be helping me with my listings. Does he/she need to become a member in order for his/her contact information to be on my listings?

Yes, they can and should join as an admin/secretary, for which there might be a membership fee by the association.

29. Can I state the commission is split 50/50 or subject to lender approval?

No. According to the MLS rules, you cannot state the commission. Read more here
