What does off-market mean in real estate? The Luxembourg version

What does off-market mean, exactly?

Literally "off the market": the property is for sale, but not on the visible market. It appears on no portal, in no agency window, on no social network. It is presented directly, one by one, to buyers whose project and financing the agent already knows.

It is neither a cut-price sale nor a hidden sale. The price is set on the same references as any other sale, signed prices: an average of €7,712 per m² for an existing apartment in Luxembourg over the twelve months to the end of June 2026, according to the Observatoire de l'Habitat and STATEC (gouvernement.lu). What changes is how the buyer is reached, not what the property is worth.

Luxembourg has no official statistic on the share of off-market sales. For an order of magnitude, in the United Kingdom about one sale in ten in 2022 happened without public marketing, and nearly one in four in London and prime markets, according to Hamptons (PrimeResi). That is a British benchmark, not a Luxembourg one, but it shows that discretion is nothing exotic.

Off-market, pre-market, coming soon: what is the difference?

It all comes down to one question: will the property end up in a public listing? Off-market, no, unless you change strategy. The whole sale takes place in a closed circle, from first contact to signature.

Pre-market is a test phase. The property is shown discreetly, for a few weeks, to a network of buyers before it goes online. If an offer comes in at the right price, the sale closes without a listing. If not, the public listing follows, with a price already tested on real buyers. "Coming soon" goes the other way: it is a public listing announcing a listing. Teaser photos, a sign, a "coming soon" banner: the aim is to build anticipation, not discretion.

Off-market: never public. Pre-market: private first, public later if needed. Coming soon: public from the start, as a preview.

All three have their logic. A standard apartment in a sought-after commune can benefit from a short pre-market. An exceptional house, a let property whose tenants you do not want to worry, a delicate estate or a publicly known owner belong rather in true off-market.

Why do so many sellers in Luxembourg choose discretion?

Because the country is small, dense with agencies and wealthy. In its 2023 inquiry, the Autorité de la concurrence counted 1.99 estate agencies per 1,000 inhabitants, the highest density in Europe, against 0.83 in France and 0.35 in Germany (Paperjam). A property put online is quickly picked up, shared and talked about. Every price cut shows, and so does every month spent online.

Luxembourg also has the highest median wealth per adult in the world, €336,498 according to UBS (IndexBox). At the top end, where asking prices reach €12,578 per m² in Belair according to Immotop (Chronicle.lu), many owners want neither their living room on the internet nor their address linked to a price. Some buyers also prefer not to be seen at viewings. Discretion serves both sides.

What stays public no matter what?

The deed, its price and the statistics. In Luxembourg, every property sale goes through a notarial deed, transcribed at the Publicité foncière in one of the three mortgage registry offices: Luxembourg I, Luxembourg II or Diekirch. Article 2196 of the Civil Code obliges these offices to deliver copies of transcribed deeds "to all who request them", for a fee (Luther). In other words, anyone can obtain the deed and the price, provided they make the request.

The cadastre, for its part, records parcels, their areas and the holders of rights. According to the same note, consultation on geoportail.lu and requests for a cadastral extract are free. The exact conditions for access to the owner's name should be checked with the cadastre administration. Finally, the Observatoire de l'Habitat and STATEC publish aggregated prices from the deeds, by commune, canton and size band. No individual sale appears there, but your transaction feeds into the average.

The conclusion is simple: a sale is never secret in legal terms. Off-market controls the marketing phase, meaning who sees the property, when and with what information. It does not erase the official trace of the sale, and no serious agency should promise you otherwise.

What has the RBE restriction changed since February 2025?

It better protects the identity of people who hold property through a company. On 22 November 2022, the Court of Justice of the European Union invalidated general public access to registers of beneficial owners, and Luxembourg suspended that access the same day. A law in force since 1 February 2025 now reserves the RBE for national authorities, professionals subject to anti-money-laundering rules such as notaries, lawyers and accountants, and persons with a legitimate interest, on a justified request (IFC Review).

In practice, if your property belongs to a property company (SCI) or an SA, the general public can no longer trace it back to you through the RBE. The company itself remains visible at the Publicité foncière and in the trade register. Discretion improves, it does not become absolute. Before restructuring how you hold a property for this reason alone, talk to your notary: the tax consequences often weigh more than the gain in confidentiality.

Is off-market always the right choice?

No, and it needs saying. Fewer buyers see the property, so there is less competition between them. If the starting price is off, nobody will correct it upwards. The Autorité de la concurrence has also criticised the bidding-up by some agencies that win mandates with prices disconnected from the market (Autorité de la concurrence). Off-market, that mistake costs even more, because no public market brings you back to reality.

Off-market works when three conditions are met: a valuation based on real sales, a network of qualified and vetted buyers, and a seller who accepts a sometimes longer timeline in exchange for discretion. If one is missing, a short pre-market or a well-prepared public sale is the better option.

How do you know if your property suits off-market?

Start with the price. Use the free estimator at secretimmo.lu/valuation: you get a price range in two minutes. Secretimmo is an off-market agency and platform, not a listings portal. We then match your property against the buyers in our network and tell you frankly whether it will do better staying discreet or going public. The valuation is free if a mandate is signed within a week, otherwise it costs €600 excl. VAT. Our fees: 5 % off-market, 3 % for a public exclusive mandate.

Rules on access to registers change: this information is indicative and does not replace the advice of your notary or tax adviser.

Frequently asked questions

What does off-market mean in real estate?

An off-market property is for sale without being publicly advertised: no portal, no photos online, no published price. It is presented directly to identified buyers whose project and financing have been checked.

What is the difference between off-market and pre-market?

Pre-market is a period of a few weeks during which the property is offered privately before it may go online. Off-market, the property never appears in a public listing, unless the seller changes strategy.

Does an off-market sale stay secret in Luxembourg?

No. The notarial deed is transcribed at the Publicité foncière, and Article 2196 of the Civil Code obliges the mortgage registry offices to deliver a copy to anyone who asks. Off-market protects the marketing, not the deed.

Will my property's price appear in official statistics?

Only in aggregated form. The Observatoire de l'Habitat and STATEC publish average prices by commune, canton and size band, never an individual sale.

Can the RBE still reveal who owns a property company?

Not to the general public. Since 1 February 2025, access is reserved for authorities, professionals subject to anti-money-laundering rules such as notaries, and persons with a legitimate interest. The company remains visible at the Publicité foncière and in the trade register.
