There is a quietly transformative shift underway in Paris’s luxury real estate scene.
Once regarded as a fringe strategy for selling the rare and wonderful of Paris’ high-end property segment, off-market sales are now reshaping how the city’s most coveted homes are traded.

As 2025 unfolds, this discreet market is no longer just an alternative – for many ultra-prime buyers and sellers it’s now the preferred path.
Paris’ off-market projections
Sales data from the past year says as much. For property sales priced €3 million-plus (US$3.5m) – particularly in the central arrondissements – industry estimates range from about 5% to 20% being off-market, while some boutique brokers say the vast majority of €7m+ listings are handled privately.
For example, property experts ParlezMoiDeParis say while “difficult to estimate” they believe around 10% to 20% of all property sales are being made off-market, and the highest proportion of those sales are for luxury property.
Others, such as Home Catcher give lower-end, practical estimates – commonly 5–15% (or 5–10%) for off-market activity in general markets – but also note the proportion rises in the top-end.
Tightening Paris supply drives off-market activity
The broader market context helps explain why off-market activity is gathering pace: transaction volumes in Paris have softened in recent years even as prime values have held up, according to data from Knight Frank. This has created a tighter supply backdrop in coveted central arrondissements.
As a result, sellers and agents are being pushed towards more controlled, discreet routes to match their wealthy clientele with the rarest stock.
Truly exceptional homes, such as the penthouse suite of a 19th-century hôtel particulier – Parisian townhouses – overlooking the Seine will almost certainly be sold through off-market channels.
Some agencies report that more than half of their ultra-luxury inventory never appears on public listings at all, with sellers relying instead on private introductions and direct client networks.
Discretion, control and variety an encouragement
The attraction is clear. For high-profile clients, visibility has become a liability, and publicity often feels more like intrusion than opportunity. Discretion and control are now part of the product itself.
At the same time, scarcity is a defining feature of the Parisian prime market. In districts such as the 7th, 8th and 16th arrondissements, supply is constrained and competition is fierce.
Buyers willing to engage through private networks gain access to rare opportunities before they are ever visible to the broader market. Increasingly, the process is less about browsing listings and more about being matched to a property through long-established relationships.
Two categories of property illustrate the trend most clearly. Hôtels particuliers, remain among the most desirable assets in the city. Behind elegant façades lie private gardens, secure garages and staff quarters – amenities that are vanishingly rare in central Paris and which speak to a lifestyle of privacy and exclusivity.
Property types impact sales route
Publicly advertised townhouse listings are dwindling. Fewer than 150 were marketed in 2024, while inquiries via off-market channels numbered nearly double that for homes priced between €5m and €15m. This is a segment where the whisper market has become the dominant route.
The second category is last-floor and rooftop apartments with terraces or panoramic views. In the Haussmannian and pre-war buildings that define the city’s skyline, rooftop extensions are tightly restricted or outright impossible, making existing inventory all the more precious.
Apartments with terraces or balconies in Paris often command considerable premiums – up to 10% depending on location – over those without outdoor space, according to brokers such as Meilleurs Agents. This outpaces the broader luxury market.
Some boutique brokers report that a majority of rooftop sales above €4 million are now arranged off-market, often through private agreements arranged well before any public exposure.
Etiquette behind off-market moving
The mechanics of the off-market world demand a different approach from both buyers and sellers. Trusted agencies, family offices and seasoned brokers act as the gatekeepers, with access to select inventories that rarely reach digital platforms.
Buyers must demonstrate seriousness early, often providing proof of funds before viewings are arranged. The process favours speed and efficiency but also places a premium on relationships and trust.
Sellers, meanwhile, gain by limiting unnecessary exposure and by engaging only with qualified prospects. Many also find that concentrating demand among a small pool of motivated buyers can result in more favourable pricing than if the property were openly listed.
A continuing driving force for Paris’ property market
What does this mean for the Parisian ultra-prime market going forward? The answer is that off-market sales are no longer a discreet undercurrent; they are becoming the standard way the city’s most exceptional homes change hands.
Townhouses and rooftop apartments are emblematic of this shift, embodying both heritage and scarcity, while also signalling the modern buyer’s priorities of privacy, uniqueness and controlled competition.
For sellers, off-market channels provide greater autonomy and assurance. For buyers, success increasingly depends on patience, connections and readiness, with advantages accruing to those who can move swiftly and decisively when opportunities arise.
In a city where history and scarcity are the twin currencies of prestige, Paris’s whisper market has become impossible to ignore. It may operate in the shadows, but in 2025 it is the quiet force defining the ultra-prime landscape.
