Off-market property in Paris, from first lead to completion

Off-market property in Paris means homes and buildings sold without public marketing: no portal listing, no agency window, no photographs online. The owner chooses discretion and offers the property to a handful of serious buyers introduced by professionals they trust. Acropolis Real Estate acts only for buyers: we find these properties, check them thoroughly and negotiate on your behalf.

The Paris off-market property market at a glance

There are no official statistics on unadvertised sales, because notaries record a transaction without knowing whether it was ever listed. Industry professionals generally estimate that 15% to 25% of transactions in the most sought-after arrondissements (6th, 7th, 8th and 16th) take place without a public listing, and that the share rises markedly above €2 million. Treat these as orders of magnitude, not hard data.

Market conditions matter too. According to the Notaires du Grand Paris, the average price of existing apartments in Paris held steady at around €9,600 per m² in the first quarter of 2026, while prime arrondissements such as the 8th and 16th were showing year-on-year falls at the end of 2025. In a calmer market, many sellers prefer to test a price quietly rather than leave a property online for months.

Why owners sell without advertising

The reasons are often personal, and understanding them is part of negotiating well:

• Privacy: public figures, business owners and families who do not want their interiors or address exposed.
• Estates and separations: situations where a quick, quiet solution is preferred.
• Price testing: a seller sounds out a few buyers before deciding on a formal launch.
• Buildings and offices: an investor disposing of an asset without alerting tenants or competitors.
• Security: high-value homes, art collections and sensitive addresses do not suit open viewings.

Our guide to finding off-market property in Paris looks in detail at the channels through which these properties circulate.

Off-market versus listed: what changes for the buyer

An off-market home is not automatically cheaper. It is less exposed: the advantage lies in access and in negotiating without a bidding war. Our job is to check that the asking price is consistent with comparable sales, not to make you pay a premium for scarcity.

How we reach unlisted homes

The discreet market runs on trust. An owner opens the door only to a buyer whose intent is established and whose discretion is vouched for by a professional. Our work happens in two stages.

Upstream, we present your search anonymously to our network: notaries, wealth managers and private banks, family offices, partner prestige agencies, architects, building managers and owners. Each contact knows exactly what you are looking for and that the budget is funded.

Downstream, we qualify every proposal before it reaches you: a preliminary viewing, a review of the file, a price analysis and a check of the seller's legal position. You see only what deserves your time.

To judge a price without a public listing to compare against, we rely on recent notarial sales in the same building or street and on our knowledge of each area. Our guide to Paris prime real estate neighbourhoods and prices gives the benchmarks we start from.

The international network of our founder, Nicolas Milonas, built over more than 25 years of cross-border investment between Europe, Asia and the Middle East, is an asset here: it also reaches foreign owners selling a Paris property without going through an agency. His background is set out on our about Acropolis Real Estate page.

The legal framework: the Hoguet law and due diligence

Off-market does not mean outside the rules. In France, the Hoguet law of 2 January 1970 governs all property intermediation: a professional must hold a licence and a written mandate before acting. On the seller's side, the property is covered by a sale mandate, often with a confidentiality clause. On the buyer's side, we act under a search mandate that defines the assignment and the fees.

Disclosure obligations are the same as for any sale. Before you commit, we check in particular:

• Mandatory surveys: energy performance certificate (DPE), asbestos, lead, electrics, gas, termites, natural-risk report and certified floor area.
• Co-ownership records: minutes of recent general meetings, building regulations, maintenance log, approved works, the multi-year works plan, service charges and arrears.
• Title and planning: the seller's title, easements, compliance of past works and the permitted use of the premises (residential or office).
• Timeline: preliminary contract before a notary, a ten-day cooling-off period for a private buyer of a home, then the final deed, usually two to three months later.

A discreet sale can move fast. That is exactly when these checks protect the buyer.

A typical off-market assignment

The following illustrates how an assignment usually unfolds. It is not an account of a real transaction.

1. Brief: a buyer based abroad wants a four-bedroom family apartment in the 7th, with a view and a lift, and does not want their name to circulate.
2. Mandate and anonymous outreach: the search is described to the network without identity, backed by proof of funds.
3. Leads arrive: several proposals come in, some off-brief; we view a few and keep two.
4. Viewing and analysis: the buyer spends one day in Paris, with a full file on each property.
5. Negotiation: the offer rests on comparable sales and on the works the building will need.
6. Signing: preliminary contract under power of attorney, then the final deed a few weeks later.

Actual timing depends on the market and the brief. We do not guarantee timelines, but we give you an honest estimate from the outset.

Fees, confidentiality and international buyers

Our fees start from 2% of the purchase price (VAT included), with a minimum fixed fee quoted on request, and are payable only if you buy. We never charge for access to a list of properties. Our article on property finder fees in France explains market practice.

For non-resident buyers, we coordinate financing (French lenders typically ask for a larger deposit), structuring with your advisers and remote signing. If your plans reach beyond Paris, the same method applies to off-market villas on the French Riviera and to prime residences and offices across Europe.
