The Off-MLS Debate Has a Data Problem
The real estate industry is in the middle of a heated conversation about off-MLS marketing, and much of it is generating more heat than light. Critics have focused their attention squarely on Compass and its structured approach to pre-market and private listings, framing the brokerage as if it invented a practice that circumvents the Multiple Listing Service. But according to Compass International Holdings Chief Economist Mike Simonsen, that framing ignores a fundamental truth baked into the data: off-market selling was already happening at massive scale long before Compass formalized anything.
The number at the center of Simonsen's argument is 1.4 million. That's the estimated volume of existing listings that transact each year entirely outside the MLS, without any structured pre-market program, without institutional backing, and largely without scrutiny. If the industry is serious about protecting consumers and promoting transparency, that's where the conversation needs to start — not with a single brokerage's branded marketing strategy.
What Compass Actually Built
To understand Simonsen's argument, it helps to be clear about what Compass did and did not do. Compass did not create off-market real estate transactions. Private sales, pocket listings, and deals made through personal networks have existed for as long as real estate has been a profession. Wealthy sellers have long preferred discretion. Agents have always known people. Properties have always changed hands quietly.
What Compass did create was the first large-scale, structured, and transparent framework for managing the pre-market phase of a listing. Its program gives sellers an organized way to test market interest before going live on the MLS, with defined timelines and explicit opt-in consent. Rather than a handshake deal conducted in the shadows, Compass built a documented process with guardrails.
Simonsen's point is that this distinction matters enormously. A structured alternative to an existing practice is fundamentally different from the practice itself. When critics conflate the two, they end up arguing against the more transparent version of something that isn't going away regardless of what any policy body decides.
The 1.4 Million Listings the Debate Ignores
Here is where the data becomes impossible to dismiss. An estimated 1.4 million real estate transactions per year occur outside the MLS with no structured framework, no formal pre-market program, and no organized accountability. These are deals struck through agent networks, seller relationships, and informal channels that leave buyers with little visibility and sellers with no institutional support guiding their choices.
These transactions don't make headlines. They don't inspire industry task forces. They don't generate op-eds about consumer harm. Yet by virtually any measure of transparency or fair access, they represent a far larger and less regulated portion of the off-market universe than anything Compass has built.
The selective focus on Compass while 1.4 million informal off-market transactions proceed each year raises legitimate questions about what the debate is truly about. If the concern is genuinely about consumer protection and equal access to listings, the industry's energy would be far better spent addressing the broader, unstructured off-market ecosystem than targeting the one player that actually formalized the process.
Why the MLS-First Argument Isn't as Simple as It Sounds
Proponents of mandatory MLS-first rules argue that listing a property on the MLS before any other marketing gives all buyers equal access and produces the best outcomes for sellers through maximum exposure. It's a reasonable principle on its face, and maximum exposure does often correlate with stronger offers and better prices.
But the argument becomes more complicated when you apply it uniformly across every seller situation. Some sellers have privacy concerns that are entirely legitimate — high-profile individuals, people going through divorce, estate sales with family sensitivities, or simply homeowners who don't want a parade of strangers through their homes before they're ready. For these sellers, a pre-market window isn't an attempt to game the system. It's a practical tool that reflects the reality of their circumstances.
Simonsen's broader argument is that policy should grapple with this complexity rather than defaulting to one-size-fits-all mandates that ignore why sellers seek alternatives in the first place. Structured pre-market programs, done with proper disclosure and seller consent, can actually serve those sellers better than leaving them to navigate informal off-market channels entirely on their own.
Transparency as the Real Standard
If there is a productive path forward in the off-MLS debate, Simonsen's perspective suggests it runs through transparency and informed consent rather than blanket prohibition. The question should not simply be whether a listing appears on the MLS first. It should be whether sellers fully understand their options, whether buyers have reasonable visibility into available inventory, and whether the process — whatever form it takes — is documented and accountable.
By that standard, a well-structured pre-market program with defined timelines and explicit seller consent compares favorably to the alternative: 1.4 million annual transactions conducted through informal channels with no oversight whatsoever.
What the Industry Should Actually Be Talking About
The off-MLS debate is not going to disappear, and the underlying tensions it reflects — between seller autonomy and buyer access, between innovation and standardization, between private discretion and public transparency — are real and worth working through carefully.
But any honest reckoning with those tensions has to start with the full picture of how off-market real estate actually works today. That means looking at all 1.4 million transactions happening outside the MLS every year, not just the ones operating under a recognized brand with a formalized program that critics can point to.
Compass didn't invent the problem. It built a structure around something the industry was already doing informally at enormous scale. Whether that structure is the right one is a fair question. But dismissing it while ignoring the broader off-market reality it was designed to address isn't a policy argument — it's a distraction.
