Slightly more than 600 multiple listing services (MLSs) operate in the United States and Canada that are the envy of the global real estate industry. Cooperation and the offer of compensation among participating brokers create the foundation for these organizations. Over time, these principles have transformed MLSs into the epicenter of technology for real estate agents, creating nation-wide marketplaces.

Subsequently, many technology companies have developed add-on software that enables MLSs to add helpful services to the core MLS software.

In this guide to software, delivered primarily through the MLSs, RE Technology highlights a variety of applications that enable a richer and more effective platform for agents, brokers, and the consumers that we serve. As our industry changes, these technology tools integrate into multiple listing platforms to drive innovation and end-to-end services.

Please enjoy this overview and let us know if there are additional products that you believe we should feature in future RE Technology Success Guides.

A number of significant trends are emerging to shape America’s MLSs today.

  • Real Estate Standards Organization
  • Security for Authentication and Data
  • Systems Integration for Single Sign-On
  • Smart Bi-Directional Data Integration Between Applications.

The Real Estate Standards Organization became a different organization a few years ago when the National Association of REALTORS® (NAR) adopted an MLS policy that requires all NAR® affiliated MLSs to adopt the standards or face the revocation of their charter. Over the past few years, this encouragement by NAR® has catapulted MLSs into high gear to adopt the RESO data dictionary to normalize data fields, and the WebAPI to replace RETS as a more contemporary transportation method. All of this effort goes a long way to reducing the costs of connecting software to MLS data, providing an extraordinary benefit to all broker and agent subscribers to the MLS.

MLSs have also made great progress on adding access security. Perhaps only a hundred or so MLSs remain that have yet to lock down password sharing. MLS system developers have wisened to best practices on security too. Systems protect against hacking by taking added security measures. Application programming interfaces (APIs) have security, and firms connecting to MLS data require higher levels of authentication. Additionally, leading MLSs have begun to follow a technique called data seeding. This process drops little seeds of data into data feeds that allow the MLS to “watch” where the data goes. Soon you will see the news stories of data pirates being charged with theft. Exciting!

A key barrier to adopting MLS services and software extensions was username and password management. Frankly, remembering the MLS password is hard enough – now imagine remembering a dozen or more passwords to access the many software extensions to an MLS. That has been solved through MLS Single Sign-On. When a user signs into the MLS, they are automatically signed onto other software applications without the need to log in to each one of them – ergo the term – single sign on. We are delighted to see more than listing data being shared across software in the MLS today. In this new era of connecting software and data using APIs, the MLS system can now securely send and receive customer records, saved searches, saved favorites, and many other consumer-centric data that an agent needs to manage. Agents can send these records easily, without being required to re-key the data. This not only saves real estate professionals valuable time but improves accuracy and reduces the likelihood of an error that could compromise a transaction.

These are exciting days for our nation’s MLSs. More than ever before, they can assemble a group of software products that work together to design an effortless system of productivity. We will illustrate this trend through the narrative of applications covered in this guide.

RE Technology dedicates a private section of digital publication specifically to MLS related software. Because these solutions are not sold to agents or brokers, only our MLS subscribers have access to this section of the site.

Always start with the price. If products being offered to the MLS are not priced in line with expectations, looking at the software is a waste of time unless you have already gotten your board to agree to a price increase. If a price increase is out of the question, there is no need to look at more expensive products than you can afford.

Negotiate with your existing vendor first. We know that the cost of switching technology vendors is very expensive. It requires more training, support, and communication activities and those require capital and labor. Unless your subscribers hate your current product, or the company is not supporting you correctly – stick with what you have or budget correctly to deliver a new and better service.

Check their references. It is pretty commonplace for technology companies to have a handful of favorite customers. You want to check references carefully by looking at similar sizes of MLSs who offer the product. You also want to talk to some new customers about the onboarding process and some old customers about the company’s dedication to improving the product on a regular basis. By the way, it is also a good idea to check to see if the company is a member of the Real Estate Standards Organization and if they are certified.

Find out how long the new vendor will run in parallel before the billing starts. Nothing can hurt a new product launch more than a cut over that happens before it should.

Take a very close look at the contract terms and conditions, especially the data licensing agreement. These are critical business terms to your contract that are sometimes looked over. Also, be certain to negotiate your exit. You need to enter a contract through the lens of failure. You may also want to negotiate growth and shrinkage into your agreement by securing the pricing levels in advance.

Reporting is one of the most overlooked areas of buying MLS products. Insist on reports that show the number of daily users, weekly users, monthly users. You should be able to pull reports on those users to check on their satisfaction with the product. You may also want to enlist the support of the vendor at driving adoption. Alternatively, rather than negotiating a site license, only purchase licenses for the average number of monthly unique users.


Today’s era of MLS consolidation mandates responsiveness in the delivery of services to the brokers and agents that you serve. The complaints that lead to MLS consolidation are pretty consistent. Understanding these complaints and learning how to respond to them will position your MLS for high levels of customer satisfaction and a platform for expansion.

The biggest complaint among brokers and agents is customer support and training. Whenever brokers and agents feel like the MLS is out to get them, there is a problem. If your customer calls and you can’t take care of their problem, the problem is you. These are pretty strong statements, but you must understand that your customers are your biggest fans when you are doing a great job. Customers belonging to more than one MLS will be very outspoken about which MLS is better. Be sure to meet with your large brokers, top producing agents, and survey everyone to learn what you can do better. They will give you the answers.

MLSs can become more attractive with the array of products they offer for the fees they charge is a classic economic model of return on investment. An MLS delivering great service on top of highly satisfying technology at a reasonable price likely will grow. Price is a pain point for many agents and brokers when the services offered beyond the core MLS system are not appropriately valued. Research the offerings of nearby MLSs to make sure that you are competitive.

Building a great core technology stack for basic MLS services is table stakes today, but many MLSs have developed a premium service. In some cases, MLSs offer an array of technology for a very low bundle price. In other cases, MLS support brokers and agents with a la carte pricing for specialty software. The value of the MLS in both of these premium subscription models includes data integration, support, training, and much lower prices.

Lastly, it is important for MLSs to be extremely skilled in data management. MLSs who have technical staff that can manage data are in a much better position than MLSs who need to rely on a vendor. A growing MLS needs to be able to manage the details of system migrations and data shares. Having this skill assures that a growing MLS does not drop the ball on onboarding new customers.
