Private Listings, Buyer Representation, and the Future of Portugal’s Real Estate Market

A debate that has been simmering in the American real estate industry for years is finally spilling into the legislative arena.

New York is considering legislation that would restrict private home listings, joining states such as Washington and Connecticut in challenging a practice that many industry insiders have long defended.

The proposed law doesn't eliminate seller choice, but it does force a conversation that the real estate industry often prefers to avoid: Who benefits when property listings are kept private?

The answer is not always the seller.

For generations, many real estate businesses were built on controlling access to information. The professionals with access to the most information often held the greatest advantage. Buyers didn't see every available property. Sellers couldn't always verify whether their home had reached the widest possible audience. Agents controlled access to inventory, and that control became part of their value proposition.

The internet changed that reality years ago and the industry is only now catching up.

Imagine telling a homeowner that before selling their stock portfolio, you planned to show it to only a handful of potential buyers. Or imagine an auction house deliberately excluding most bidders from participating in a sale. The logic falls apart almost immediately.

Yet in real estate, limiting exposure has often been presented as a legitimate strategy.

Sometimes it is. Privacy matters. High-profile individuals, sensitive family situations, or security concerns can justify a discreet sale. But these cases are the exception, not the rule. Too often, private listings and off-market properties serve the interests of intermediaries more than the interests of the homeowner.

The fundamental question is simple. If a seller's objective is to achieve the highest possible price under the best possible terms, why would they voluntarily reduce the number of people competing for the property?

Competition is not a flaw in a marketplace. It is the mechanism that determines value.

The debate is not merely theoretical. Over the past year, two of the largest players in American real estate, Compass and Zillow, fought a highly public battle over private listings. Compass argued that sellers should have the freedom to market properties privately before broader exposure. Zillow countered that housing markets function best when inventory is visible to everyone and buyers have equal access to listings.

While the legal dispute was eventually resolved, the underlying question remains: should access to property information be controlled by brokerage networks, or should transparency be the default?

Increasingly, regulators, consumer advocates, and many technology platforms appear to be answering that question in favor of greater openness.

For additional context on Zillow's position.

Beneath the legal arguments lies a larger question. Should real estate professionals create value by controlling information, or by helping consumers navigate information?

The future of the industry may depend on the answer.

The winners of the next decade will not be gatekeepers. They will be advisors.

The fact that this debate has reached courtrooms, boardrooms, and now state legislatures suggests something bigger is happening. The industry is being forced to reconsider whether controlling information is still a sustainable business model in the digital age.

This is why the debate unfolding in New York deserves attention far beyond the United States. It touches on a broader issue that is highly relevant here in Portugal.

Portugal's real estate market has evolved dramatically over the past decade. The buyer pool is now global. International investors, digital entrepreneurs, retirees, and families from across Europe and North America are all competing for opportunities in Portuguese cities and coastal markets.

The buyers have modernized.

The market infrastructure has not.

Portugal has attracted a global buyer base, yet much of the industry still operates on assumptions developed for a local market twenty years ago.

Property information remains fragmented across portals, brokerage networks, private databases, WhatsApp groups, and informal agent-to-agent relationships. There is no universally shared marketplace. There is no complete view of available inventory. Many buyers never see every property that matches their criteria, and many sellers have no reliable way of knowing whether their property was truly exposed to the entire market.

For an industry that prides itself on professionalism, that should be uncomfortable.

Portugal's real estate market has become remarkably digital without becoming truly transparent.

We have modern portals, sophisticated marketing tools, AI-powered search capabilities, and unprecedented global demand. Yet buyers still struggle to see the entire market, and sellers still struggle to know whether they have reached it.

Portugal's market has become so dependent on portal distribution that many industry participants have begun to confuse visibility with transparency. They are not the same thing.

A property appearing on a dominant portal such as Idealista may be highly visible, but that does not necessarily mean the marketplace itself is open, collaborative, or fully transparent. Visibility is important. Transparency is something much bigger.

A truly transparent marketplace is one where buyers can confidently access available inventory regardless of which brokerage controls the listing. It is one where agencies cooperate because it serves the client. It is one where information flows efficiently, allowing the market itself to determine value.

Portugal arguably has a dominant portal. What it does not yet have is a fully transparent marketplace.

Transparency is often portrayed as a threat to real estate professionals. In reality, the opposite is true.

The agents who fear transparency are usually competing on access. The agents who embrace transparency compete on expertise.

Consumers increasingly understand this distinction.

A seller doesn't need someone to hide information. A seller needs someone who can interpret information, position an asset correctly, negotiate effectively, and guide a transaction to a successful closing. Those skills become more valuable, not less, when markets are transparent.

The same is true for buyer representation.

As buyer representation becomes more established around the world, buyers increasingly expect their advisor to provide a complete view of the market, not merely access to the inventory controlled by a particular brokerage. When listings are scattered across private networks, closed databases, and brokerage silos, buyers are forced to wonder whether they are seeing everything that is available or simply everything that happens to be accessible through a particular channel.

That uncertainty undermines trust.

The most consumer-friendly real estate markets are not the ones where buyers need to know the "right agent" to discover opportunities. They are the ones where every qualified buyer has access to the same inventory and where professional advisors create value through insight, negotiation, and advocacy.

Research highlighted by Realtor.com found that homes marketed privately took significantly longer to sell and showed no measurable pricing advantage compared to properties exposed to the broader marketplace. Researchers also concluded that fragmented inventory systems disadvantage both buyers and sellers by limiting access to information and reducing market transparency.

The future of real estate will belong to advisors, not gatekeepers.

What is happening in New York reflects a broader shift taking place across many industries. Consumers are demanding visibility. They want to understand their options. They want confidence that they are seeing the full picture before making one of the largest financial decisions of their lives.

Real estate should not be exempt from those expectations.

Portugal has an opportunity to learn from this discussion before regulators eventually force the issue. The industry can choose to move toward greater openness on its own terms, or it can wait until public pressure makes change unavoidable.

History suggests that industries rarely regret becoming more transparent. They usually regret waiting too long.

The question facing real estate is no longer whether information should be open.

That battle was settled years ago.

The real question is which professionals will thrive once it is.

My bet is on the advisors.
