Viager Explained: Buying a French Home With the Owner Still Living In It

Published on: June 9, 2026

Quick answer: A viager lets you buy a French property at a discount, with no mortgage, while the seller keeps living in it for life. The buyer (débirentier) pays a bouquet, an upfront cash sum, usually 20% to 40% of the occupied value, plus a rente viagère, a lifetime annuity to the seller (crédirentier) that stops when they die. In the most common form, viager occupé, the seller stays in the home and the price carries a décote of roughly 25% to 45%, calculated actuarially from the seller's age (commonly via the Daubry scale). The core risk is longevity, if the seller lives a very long time, as in the famous Jeanne Calment case, you keep paying for decades, so treat a viager as a long-dated, illiquid, cash-funded commitment rather than a quick discounted purchase.

There is a way to buy a French property at a steep discount, with no mortgage, while the current owner keeps living in it for the rest of their life. It is called a viager, and it is one of the most distinctive transactions in European real estate. It is also, quite openly, a bet on how long someone lives, which is what makes it fascinating, controversial, and worth understanding properly before you go near it.

This guide explains how a viager actually works in 2026, the numbers behind the discount, the risks (including the most famous cautionary tale in property history), and what foreign buyers in particular need to watch.

What a viager is

A viager is a property sale structured around uncertainty. Under French law it is a contrat aléatoire, an "aleatory contract", because its total price depends on something nobody can predict: the seller's lifespan.

The two parties have specific names. The seller is the crédirentier. The buyer is the débirentier. Instead of paying one lump sum, the buyer typically pays:

• A bouquet, an upfront cash payment made on signing, usually 20% to 40% of the property's occupied value.
• A rente viagère, a monthly (or quarterly) annuity paid to the seller for as long as they live.

When the seller dies, payments stop and the buyer holds the property outright. The longer the seller lives, the more the buyer ends up paying. That uncertainty, the aléa, is not a flaw; it is legally what makes the contract valid.

Occupé, libre, and the variations

There are a few structures, and the difference is mostly about who gets to use the property.

Viager occupé is by far the most common, around two-thirds of all viager transactions. The seller stays in the home until death, retaining a Droit d'Usage et d'Habitation (DUH), the right to use and occupy. Because the buyer cannot use or rent the property in the meantime, the price is discounted significantly.

Viager libre is rarer (roughly one in seven deals) and usually involves a second home. The seller moves out, so the buyer can occupy or rent immediately. There is no occupancy discount, so the price is higher.

There are two related structures worth knowing. In a nue-propriété with reserved usufruit, the seller keeps the usufruit, the broader right not just to live in the property but to rent it out and collect the income, while the buyer holds the bare ownership (nue-propriété). And in a vente à terme, the buyer pays installments over a fixed, predetermined period rather than until death, which removes the longevity gamble.

How the discount is calculated

The headline appeal of viager occupé is the décote, the reduction from the property's normal market (vacant) value. It typically runs 25% to 45%, and it is not arbitrary. It is calculated actuarially from the seller's age and statistical life expectancy, most commonly using the nationally recognised Daubry scale (with a technical rate around 4.5%) or actuarial mortality tables.

The logic is simple: the older the seller, the shorter the expected occupation period, the smaller the discount and the higher the price. A 90-year-old seller commands a much smaller décote than a 70-year-old. The bouquet and the rente are then derived from this occupied value and split according to what the seller needs upfront versus monthly.

The market in numbers

The viager is no longer a fringe curiosity. According to market observers, roughly 5,500 viager transactions were signed in France in 2025, representing about EUR 1.5 billion in volume, and the format is growing as the population ages and seniors look to unlock home equity while staying put. The split runs about 65% occupé, 14% libre, 11% nue-propriété, and 10% vente à terme. The southeast of France alone accounts for close to 45% of activity.

The risks (and the Jeanne Calment problem)

This is where buyers must be honest with themselves. The defining risk of a viager is longevity: the seller simply lives a very long time, and you keep paying the rente for decades.

The legendary example is Jeanne Calment of Arles. In 1965, at age 90, she sold her apartment en viager to her notary, who was 47. He expected to inherit within a few years. She went on to become the longest-lived person ever documented, reaching 122. He died first, in 1995, and his widow had to keep paying the rente. By the end, the family had paid far more than the apartment was worth and never lived in it. It is an extreme case, but it captures the core gamble precisely.

Beyond longevity, watch for:

• Charges and works. Responsibility for maintenance, repairs, and property taxes is split between the parties depending on the contract type, and the buyer often carries large structural works on a property they cannot occupy.
• The clause résolutoire. If the buyer stops paying the rente, the contract can be cancelled and the seller may keep the sums already paid. Default is expensive.
• Indexation. A well-drafted contract indexes the rente (usually to the consumer price index), so the payment rises over time. Budget for that increase.
• Financing. Banks are reluctant to lend against an occupied viager because there is no clean mortgage security, so most viagers are done without credit. You generally need the bouquet in cash.

The ethics question

It is fair to feel uneasy about a transaction whose profit improves when someone dies sooner, and critics raise exactly that. The more grounded view is that a viager occupé can be a genuinely good arrangement for an asset-rich, cash-poor senior who wants to stay in their home while converting equity into guaranteed lifelong income and a tax-favoured upfront sum. The arrangement is regulated, notarised, and entirely voluntary on both sides. The discomfort is real, but so is the utility, and informed buyers treat it as a long-term commitment rather than a quick flip.

What foreign buyers should know

A viager is fully open to non-resident buyers, with a few specifics:

• A notary is mandatory. Every viager is an acte authentique signed before a French notaire, who verifies the parties, computes the rente, and registers the sale. Use an independent notary and ideally a specialist viager agency.
• Tax on the rente. The seller benefits from an age-based allowance (only part of the rente is taxed), but as the buyer you should understand the French property tax position and, if relevant, France's Impôt sur la Fortune Immobilière (IFI), the real-estate wealth tax, which can apply to the value you hold.
• The obligation is inheritable. If you die before the seller, your heirs inherit the duty to keep paying the rente, though they can also resell the viager with the seller's agreement.
• Currency and horizon. You are committing to euro-denominated payments for an unknown number of years. Treat it as a long-dated, illiquid position, not a discounted purchase.

Is a viager for you?

A viager can make sense if you have cash for the bouquet, a long time horizon, no urgent need to occupy the property, and the temperament to treat the open-ended rente as a feature rather than a frustration. It is poorly suited to anyone who needs the home soon, wants leverage, or is uncomfortable with the underlying gamble. As with any unusual structure, the due diligence (the seller's age, the contract clauses, the décote calculation, and an independent notary's review) is where the deal is won or lost.

Frequently Asked Questions

What does viager mean?

It is a French property sale where the buyer pays an upfront sum (the bouquet) plus a lifetime annuity (the rente viagère) to the seller, who often keeps living in the home until death.

How much cheaper is a viager?

In a viager occupé, the discount from market value typically ranges from 25% to 45%, calculated from the seller's age and life expectancy using the Daubry scale.

Can a foreigner buy a viager in France?

Yes. There is no nationality restriction. The sale must be completed before a French notary, and bank financing is usually unavailable, so buyers generally need cash for the bouquet.

What happens if the buyer dies before the seller?

The buyer's heirs inherit the obligation to keep paying the rente. They may continue payments or resell the viager with the seller's agreement.

What is the difference between viager occupé and viager libre?

In viager occupé the seller stays in the home (discounted price); in viager libre the property is vacant and the buyer can use or rent it immediately (higher price).
