Making a property purchase offer at the right price is the step that can turn a purchase into a successful negotiation or a missed opportunity. In France, in 2026, the market remains marked by longer selling times and more active negotiation than before, which changes the game for buyers. But you still need to know how to assess a consistent margin, draft a legally sound offer and anticipate the rest of the procedure through to the compromis de vente (preliminary sales agreement). This guide explains, step by step, how to build a credible, well-argued purchase offer suited to the local market.
In summary
- A written property purchase offer accepted by the seller legally binds both parties, generally for a validity period of 7 to 15 days.
- The average negotiation margin is around 5% in 2026, but it can reach 8 to 15% for an overpriced property or one that has been on the market for more than six months.
- The offer must state the proposed price, the validity period, the conditions precedent and the elements that justify the amount put forward.
- Once the offer is accepted, the next step is the compromis de vente (preliminary sales agreement), generally signed within 8 to 15 days, followed by the 2 to 3 months that separate the compromis from the acte authentique (notarised deed of sale).
What is a property purchase offer and what is its legal value?
A simple definition, but real consequences
A property purchase offer is a document in which a prospective buyer states in writing their commitment to buy a property at a specified price. Unlike a simple viewing followed by a verbal "I'm interested", it formalises a precise, dated intention. It also differs from a verbal purchase offer, which has no binding force and can be withdrawn at any time without consequence.
What the law says once the offer is accepted
As soon as it is delivered to the seller, the offer legally binds the person making it for the entire validity period it sets, most often between 7 and 15 days. But the decisive turning point comes when the seller accepts it in writing, without any modification: an agreement is then formed on the property and the price, which makes the sale legally "perfect" within the meaning of French law. At this stage, the seller can no longer organise further viewings or accept a competing offer, even a higher one. This is why you should never sign an offer lightly, or on a whim during a viewing.
It is essential to understand that a purchase offer is not a mere administrative formality: it is a real commitment that can bind you to the seller as soon as it is accepted.
How to assess a consistent negotiation margin?
Analysing the asking price in light of the local market
Before determining an amount, it is essential to compare the target property with comparable transactions recently completed in the same area. A property valuation carried out by a professional makes it possible to know whether the asking price reflects market reality or is overpriced. An adviser who knows the neighbourhood can also indicate whether prices are trending downward, stable or still under pressure, which directly influences the margin you can reasonably envisage.
Taking into account the time on the market
Time spent on the market is a key indicator for calibrating an offer. In 2026, a property that has been on sale for less than 30 days generally offers a negotiation margin of only 1 to 3%, whereas a property that has remained more than six months without a buyer can justify a discount of 8 to 15%. With the average time to sign a compromis de vente having reached around 107 days in the first quarter of 2026 nationwide, with significant variations depending on the city, a property that lingers well beyond this local average sends a clear signal: the seller may be willing to reconsider the price.
Factoring in works and the property's weak points
An unfavourable energy performance diagnosis (diagnostic de performance énergétique), a roof that needs redoing or a kitchen that needs renovating are all quantifiable arguments that support an offer below the asking price. The trick is to request, as far as possible, quotes or works estimates before making the offer, so as to present a negotiation amount based on facts rather than a mere impression.
What negotiation margin should be applied in practice?
Ranges observed on the market in 2026
2026 market data converge on an average negotiation margin of about 5% of the asking price, with significant variations depending on the situation: around 2% for a property that was correctly priced from the moment it came on the market, and up to 10% or even 15% for a property that is overpriced or has been available for a long time. On average, a property now sells for around 8% below its initial asking price, a figure that confirms the return of more active negotiation than in previous years.
Adapting your strategy to the type of property
A property that is overpriced by 10% relative to the market can remain for several months without a single offer, until the seller is forced to adjust the price. Conversely, a property that is correctly positioned and in high demand leaves little room for negotiation: proposing too large a discount risks simply causing you to lose the opportunity to another buyer. It is therefore essential to adjust your negotiation margin case by case rather than applying a universal percentage.
What should a property purchase offer contain?
The essential details
To be valid and credible, a purchase offer must include a number of specific elements:
- The buyer's full identity and contact details.
- The exact description of the property (address, listing reference, surface area).
- The proposed price, in words and in figures.
- The period of validity of the offer, generally between 7 and 15 days.
- The date and the buyer's signature.
Conditions precedent to anticipate
It is strongly recommended to include the intended conditions precedent in the offer from the outset, in particular obtaining a mortgage, in order to avoid any misunderstanding with the seller. Stating the method of financing (cash or credit) also reassures the seller about the seriousness of the buyer's approach. A well-constructed offer, accompanied by a short cover letter explaining the buyer's project, can make the difference against a competing offer that is equivalent in financial terms.
How to draft and submit your offer effectively?
Going through a professional rather than dealing directly
Drafting an offer with the support of a real estate advisor helps secure the formal requirements of the document and avoid errors that could invalidate it or create a later dispute. The professional also knows how to present negotiation arguments to the seller constructively, without antagonizing the other party. Browsing the property listings with the support of an expert in the field also helps you objectively compare the target property with other similar properties on the market.
Taking care over the presentation and the arguments
An offer accompanied by factual elements (market comparables, diagnostic reports, renovation quotes) is taken more seriously than a standalone offer with no justification. It is also useful to specify your personal situation (relocation, timeline, financing already pre-approved), as these details reassure the seller about the buyer's ability to see the transaction through to completion under good conditions.
What happens after the offer is accepted?
From verbal agreement to the compromis de vente
Once the offer has been accepted by the seller, both parties move towards signing the compromis de vente (preliminary sale agreement), generally arranged within 8 to 15 days. This document, most often drafted by a notary or an agency, formalizes all the conditions of the sale: final price, conditions precedent, and the expected date for signing the acte authentique (notarized deed of sale).
The timeline to the acte authentique
Between signing the compromis and signing the acte authentique, you should generally allow a further two to three months, the time needed for the legal procedures, the processing of the financing and any conditions precedent to be fulfilled. This period can vary significantly depending on the complexity of the file and the responsiveness of the various parties, particularly where a bank loan is involved.
Conclusion
Making a real estate purchase offer at the right price requires weighing several factors: the asking price, the local market context, how long the property has been on the market, and its general condition. In 2026, the average negotiation margin is around 5%, but it can be significantly higher for an overpriced property or one that has been available for a long time. A well-argued offer, drafted rigorously and supported by a professional, remains the best way to convince a seller while protecting your own interests. Being supported by a local expert makes it possible to fine-tune your negotiation strategy and to approach the next steps calmly, through to the compromis de vente and then the acte authentique.
The expert's word
"Making a purchase offer is not just about proposing a figure: it is about building a coherent file that makes the seller want to trust you. Too many buyers simply apply a "standard" negotiation percentage without really analysing the property or the local context, and end up either paying too much or seeing their offer rejected because it is perceived as disconnected from market reality. What really makes the difference is the ability to justify your offer with concrete elements: how long the property has been on the market, recent comparables in the area, work to be carried out, the energy performance diagnostic. A seller who receives a well-argued offer, even one below the asking price, takes it far more seriously than a proposal with no explanation. It should also be borne in mind that an accepted offer legally binds both parties: it is therefore never an exercise to be undertaken lightly or in the heat of the moment. At Capifrance, our advisors support each buyer in assessing a realistic negotiation margin, securing the drafting of the offer and calmly anticipating the steps that follow, through to the signing of the compromis de vente. It is this local, hands-on support that makes it possible to buy at the fair price, without losing the property you had spotted."

FAQ - Frequently asked questions
Can a real estate purchase offer be withdrawn after it has been sent?
As long as the seller has not accepted the offer, the buyer can in principle withdraw it. However, once it has been accepted in writing without modification, the offer binds both parties and can no longer be freely cancelled without risk of legal consequences.
What is the usual validity period of a purchase offer?
It is generally set at between 7 and 15 days. After this period, if the seller has not replied, the offer lapses and the buyer is no longer bound by the amount proposed.
Can you make several purchase offers at the same time on different properties?
Yes, nothing prohibits submitting several offers on separate properties as long as none has been accepted. However, you should remain vigilant: if two offers are accepted simultaneously, the buyer is legally bound on both properties.
Should you always offer a price below the asking price?
Not necessarily. For a correctly priced property that is in high demand, an offer at the asking price, or even slightly above in certain tight markets, may be the best strategy to avoid losing the property to other buyers.
What happens if the seller rejects the purchase offer?
The seller is under no obligation to accept an offer, even one at the asking price in some cases. They may reject it, not respond, or make a counter-offer, which then opens a negotiation phase between the two parties.
