What is MLS?
The acronym stands for Multiple Listing Service.
Why do I need MLS services?
This is the platform in which you will enter data for the listings your clients want you to sell.  It provides information to other MLS users as to the specifics of the property being sold.  It is where you will look for listings that your buyers want to purchase.  It is a venue for offering compensation to others for their representation of a buyer in the sale of real property.
How often do I pay MLS fees?
MLS Fees are always due before the first day of each calendar quarter.

Service fees for NTREIS MLS are paid on a quarterly basis through our GDWCAR Association Management Service (AMS) software at, using your username (NRDS # - 9 digits) and password. (Last Name with First letter Capitalized).

Why do I need to send in supporting documentation for an extension etc.? 

Having the documentation is for the protection of our members, as we do not want listings being altered without our members' written permission and it is against Association policy to update listings without documentation.  


Why am I getting a violation when this address is correct? 

Remember, you know more about your listing than the MLS Coordinator does, and the MLS Coordinator only knows what the system flags. Communication between the members and MLS Coordinator is ideal for us to handle these violations properly. 


The selling agent is outside of NTREIS, what do I enter for the SA license number? 

If the selling agent is not an MLS participant or subscriber of NTRIES then enter the following number for the SA #99999999. 

Who do I contact to update my contact information in Matrix? 

Fill out our Change of Contact and it will be updated in all systems.

Who is reporting my listing as "out of compliance"?

This information is anonymous and cannot be released. The best way to avoid “out of compliance” reports are to review your MLS Rules & Regulations to make sure your listing complies or contact your MLS Coordinator if you are unsure.

I took the correct avenues to set up my Teams for my office, why don’t I have access to certain listings? 

  1. Once your Team is registered in TREC, you can place your team in Matrix by sending in a Teams Form in with the members included along with their functions. Email this form to​.

  2. At this point every listing completed under the Team will have to be under the Team Leader, however, if team members have their own listings that you want to have access to "as a team" the listings will have to be transferred to the team leader. 

Can I search by school ratings in the MLS? 

No, however, whatever you can’t search in Matrix MLS, you can search under RPR (Realtors Property Resource) which is a one-stop-shop nationwide property database with comprehensive reports that includes school ratings feature. 

How long do I have to update my status in the MLS?

NTREIS MLS requires all updates within 72 hours of the change. Regarding Clear Cooperation, once advertised it must be listed in the MLS within 1 business day. Clear Cooperation video can be found here.


I want to use the Subdivided feature, which listing do I mark Subdivided? 

The main listing is marked “Yes” & the sub listings will all be marked “Subdivided”. 


What is List Hub? 

List Hub is the company NTREIS uses to syndicate the listings to various vendors/public sites. For more information, you can go the Links in Matrix and see what vendors/public sites are available. 

What is considered Real Property? 

The legal definition of real property is land, and anything growing on, affixed to, or built upon land. It is characterized as a property that doesn’t move or that is attached to the land.
