There is a persistent piece of folklore about buying property in France: that you should always open at ten per cent below the asking price. I have watched that opening lose two flats to other buyers, and I have watched a far politer offer win a third at a bigger discount. The number is not the strategy.

The average discount is not one number, and that matters
Start by distrusting any single figure, including the ones I am about to give you. For the first quarter of 2026, the Interkab observatory put the national gap between asking price and agreed price at around 5.3 %, the Laforêt network at 5.1 %, while the Stéphane Plaza network spoke of margins reaching 10 % in the second-hand market. These are networks measuring their own transactions, not a national register, and they do not agree.
The geography is wider still. Published comparisons of large French cities in early 2026 range from roughly 2.8 % in Lyon to 12.7 % in Nantes. So the useful takeaway is not a percentage to recite at the viewing. It is this: ask your agent what the last three comparable properties in that street actually sold for, not what they were listed at. That single question changes the conversation, because it is the only figure that binds.
The four levers that genuinely move a price
Time on the market
A property advertised three weeks ago and a property advertised seven months ago are not the same asset, whatever the listing says. Duration is the cheapest information you can gather and it costs one question. A seller who has already bought elsewhere, who is paying two sets of charges, or who has had a sale fall through, has a calendar working against them.
The energy label
This is now the strongest documented lever in France, and I will come back to it below because it deserves its own section.
Works you can cost precisely
“It needs redoing” moves nothing. A written quote from a tradesman moves a lot. Two or three quotes obtained between the viewing and the offer turn a vague impression into a number the seller has to answer. Roof, wiring, damp treatment and window replacement are the four that reliably carry weight, because nobody enjoys arguing about them.
Your own certainty
A buyer with a mortgage agreement in principle, a clear completion date and no property to sell first is worth real money to a seller. Sellers accept lower offers from buyers who will not collapse the chain, and they say so openly once you ask them why they chose someone else.
Why the DPE became the best argument in the room
The DPE, France’s energy performance certificate, stopped being paperwork and became a price. In December 2025 the Notaires de France published their green value study on 2024 transactions: houses rated G sold on average 25 % below comparable houses rated D, and for apartments the gap was 12 %. Properties rated E, F or G made up 40 % of 2024 transactions, so this is not a niche case.
The regulatory clock explains the discount. A dwelling rated G has been barred from the rental market in mainland France since 1 January 2025, F follows on 1 January 2028 and E on 1 January 2034. A buyer of an F-rated house is buying a deadline, and that belongs in the negotiation.
Better still, the seller has usually already costed the works for you. Since 1 April 2023 a compulsory energy audit accompanies the sale of a single-ownership house rated F or G, extended to class E on 1 January 2025 and due to reach class D in 2034. That audit sets out renovation scenarios with orders of magnitude. Read it before you make an offer. It is the rare document where the other side’s own expert tells you what to deduct.
One caution, and it cuts the other way. Since 1 January 2026, following an order of 13 August 2025, the primary energy factor applied to electricity in the DPE calculation fell from 2.3 to 1.9. The French government estimated that around 850,000 dwellings left the F or G bracket without any work. On this coast, where electric heating is everywhere, an older certificate may understate a flat. Check the date on the DPE before you build a discount on it.
The calendar protects you more than you think
French law gives a non-professional buyer a ten day cooling off period after the preliminary contract, running from the day after the notification is first presented. You can walk away within it, without justification and without penalty.
On top of that, if you need a loan, the suspensive condition of obtaining credit has been a fixture of French preliminary contracts since 1979. If the bank refuses, the sale falls and your deposit comes back. Never let anyone talk you into waiving it to look like a stronger buyer.
Two figures belong in your budget rather than your negotiation, and confusing the two wastes goodwill. Since 1 April 2025 French departments have been allowed to raise their share of transfer duty from 4.50 % to as much as 5.00 %, a measure running to 30 April 2028. In practice that puts total duties near 6.32 % of the price in most departments against 5.81 % in those that did not move. First-time buyers of a main residence are excluded from the 0.5 point increase. None of this is the seller’s fault, and none of it is negotiable with them.
What sinks a negotiation before it starts
- The insulting opening. A very low first offer with no supporting reason tells the seller you are not serious, and some simply stop replying.
- Criticising the decor. Taste is personal and remarks about it land as rudeness. Talk about the boiler, not the wallpaper.
- Revealing your ceiling. Saying you could stretch to a figure means that figure is now the floor.
- Negotiating twice. Reopening the price after the preliminary contract, without a genuine new finding, is the fastest way to lose a cooperative seller.
Which lever to use, and how far it usually gets you
| Lever | What you need in hand | How hard it is to refuse |
|---|---|---|
| Energy label | DPE and, where required, the energy audit | Very hard, it is documented and dated |
| Costed works | Two or three written quotes | Hard, if the quotes are credible |
| Time on the market | First listing date, price history | Moderate, it is a pressure not a fact |
| Comparable sales | Agreed prices, not asking prices | Moderate to hard |
| Buyer reliability | Agreement in principle, no chain | Not an argument, a preference, and it works |
Three questions people put to me at the school gate
Should I make my offer in writing?
Yes, and understand what it commits. A written offer accepted by the seller binds the parties in French practice, which is exactly why the amount and the conditions have to be right before you send it.
Can I still negotiate after the survey findings?
You can, if the finding is genuinely new and material. Reopening on something visible at the first viewing is what makes sellers walk. Discovering termite damage in a coastal property that was not disclosed is a different matter entirely.
Is a property that has been reduced already a bad target?
Not at all. A seller who has already cut once has accepted that the first price was wrong, which is usually the hardest step. If you can bring a documented reason, the second cut is often easier than the first.
Most of the evidence you will use comes from the inspection itself. If you are buying something with history, my list of checks to run before buying an old house is where the negotiating material tends to come from.
Get the financing settled first
A buyer whose loan is already lined up negotiates from a completely different position.
