Selling a property, the most asked questions
How much does an estate agent cost to sell a house?+
A traditional agency charges a percentage of the sale price negotiated in the mandate, which most often represents tens of thousands of euros on a house. At Briveo, the Smart plan is 2% and the Premium plan 5%, due only when the deed is signed at the notary. You can also list for free, with no mandate and no commission.
Who pays the agency fees, the seller or the buyer?+
Whoever the mandate designates. At Briveo, the fees are paid by the seller, their amount is shown in the listing, and they are only due if the sale is signed at the notary. The buyer pays nothing to Briveo.
How do you sell your house without an agent?+
Price the property at market value, have the energy certificate and the mandatory surveys done, write a precise listing with good photos, run the viewings, then entrust the preliminary contract and the deed to a notary. On Briveo, you can list for free and handle everything yourself, or let LAIA estimate, draft the mandate and prepare the negotiation with the Smart plan.
How do you get a free house valuation?+
Enter the address, the property type and the floor area on the valuation page. LAIA compares your property with the actual sales recorded by the French tax authority in your neighbourhood, adjusts for condition, floor, outdoor space and energy rating, and returns a price range with its reliability index. It is free and without commitment.
Which surveys are mandatory to sell?+
The energy certificate, mandatory from the listing onwards. Then, depending on the property, asbestos for a building permit issued before July 1997, lead for a construction before 1949, electricity and gas for installations over fifteen years old, termites and the risk report depending on the municipality, non-collective sanitation where there is no mains drainage, and the Carrez measurement for a co-ownership lot. Your Briveo file lists those that apply to your property.
Is the energy certificate mandatory to sell?+
Yes, for a dwelling. The certificate must exist before the listing is published, and the listing shows its rating. It is valid for ten years, but certificates issued before 1 July 2021 have no longer been valid since 1 January 2025. Without a valid certificate, Briveo does not draft a mandate and does not publish the listing. Land, a parking space or a cellar do not need one.
Simple or exclusive mandate, what is the difference?+
With a simple mandate, you can entrust the sale to several agencies and sell on your own. With an exclusive mandate, a single agency sells for the duration of the mandate. At Briveo, the exit rules are the same for both. You have fourteen days to withdraw (Terms 12.1), you may revoke the mandate at any time (Terms 12.7) and request its termination from your account or by any written notice (Terms 12.8). Three months after signing, either party may also give notice to end it with fifteen days' notice, in any written form, no registered letter required (Terms 12.9).
How long does it take to sell a property?+
A property priced at market value most often finds its buyer within two to three months, then allow about three months between the preliminary contract and the deed at the notary. A price set too high at the start is the first cause of delay. The Briveo valuation positions you from day one against the actual sales in your area.
Does a purchase offer bind the seller?+
A written offer at the listed price binds the seller who accepts it in writing. On Briveo, you receive offers in your account, LAIA has checked the buyer's identity and collected their financing plan, declared by them, with no check made with their bank, and you accept, decline or counter. The preliminary contract and the deed are then signed at the notary, never on Briveo.
What is the cooling-off period after a preliminary sale contract?+
A non-professional buyer has ten days from the day after notification of the preliminary contract to withdraw, without giving a reason and without penalty (article L.271-1 of the French building and housing code). The seller has no cooling-off period.
Can you sell a jointly owned or inherited property?+
Yes, provided all the owners sign the mandate and then the deed. On Briveo, each co-signatory receives their own signing link and identifies themselves separately. For an inheritance, the certificate of ownership drawn up by the notary serves as the title deed.
Is the electronic signature of the mandate valid?+
Yes. The mandate is signed online only, after identification by email and SMS, with a key created on your device. Each signature is timestamped by a third party, you receive your own copy, and the mandate is entered in the mandate register with its number, as required by the Hoguet law.
Price & commission
What is Briveo's commission?+
Two plans, Smart at 2% (self-serve sale powered by LAIA) or Premium at 5% (dedicated agent). In both cases, commission is only due at the notary signing. If your property doesn't sell, you pay no fee. You can also list for free (0%, hosting only, no mandate) if you'd rather handle everything yourself.
Are there any hidden fees?+
No. Zero setup fees, zero listing fees, zero cancellation fees on Smart. The displayed price is the total price.
When do I have to pay?+
Only after signing the deed at the notary. Legally (French Hoguet law art. 6), no real estate agent can collect payment before. We strictly enforce this rule.
Can I switch from Smart to Premium mid-sale?+
Yes, anytime. A mandate amendment is sent to you and a licensed dedicated agent is assigned promptly in your area. You can also stay on Smart and request a one-off Delegated Visit, the rate then rises to 5% only for the buyer an agent introduced, only if that buyer purchases, and after the euro amount has been shown to you upfront. The rate is fixed on the day the offer is accepted, with no automatic switch over time.
Can I do all the viewings myself and keep the Smart rate?+
Yes, and that is exactly what the Smart plan provides for. The fee clause of the mandate states that the seller carries out the viewings, and the 2% rate reflects that work being done by you. BRIVEO only carries out a viewing if you expressly request one from your account, after the matching amount in euros has been shown to you. In that case only, and only if the buyer who purchases is the one that Delegated Visit brought in, the rate rises to 5%. The rate is settled on the day the offer is accepted, with no automatic switch over time.
Process & mandate
How long does it take to get a mandate?+
The mandate is drawn up automatically by LAIA once you upload your deed and ID, then numbered and entered in the register of mandates. It is then signed online, through BRIVEO's electronic signature ceremony, and a sealed copy is handed to you.
Is a Briveo mandate as valid as a high-street agency's?+
Yes, it is the same contract under the same rules. Briveo operates under the French law of 2 January 1970, holding a professional T license and covered by a financial guarantee. The mandate is written, dated and signed electronically by the parties, one copy is handed to you (art. 6), and it carries a number from the agency's register of mandates (art. 72 of the decree of 20 July 1972). That register is kept for 10 years.
Can I terminate the mandate?+
The type of mandate is chosen separately from the plan, on Smart as on Premium. Yes, and the rules are the same whatever the type. You first have fourteen days to withdraw (Terms 12.1). You may then revoke your mandate at any time (Terms 12.7) and request its termination from your account or by any written notice (Terms 12.8). Three months after signing, either party may also give notice to end it with fifteen days' notice, in any written form, no registered letter required (Terms 12.9). Without any step on your part, the mandate runs to its term and exclusivity does not lapse on its own.
Is Briveo a real estate agency?+
Yes. French company (SIREN 952 992 634), professional license T (Real Estate Transactions) issued by the Chamber of Commerce, GALIAN-SMABTP financial guarantee €120,000. Subject to the same obligations as a traditional agency.
Which documents do you need to draw up the mandate, and which ones can wait?+
To draw up the mandate we need to identify the parties, designate the property, set the price and pick the plan. Two documents are enough to start, your title deed and your ID. To that we add details filled in online, your date and place of birth, your nationality, your occupation, your home address as distinct from the property's, then the cadastral reference, the floor area, the number of rooms, the year of construction and whether the property is occupied. If the seller is a company, the mandate also requires its name, its company number and the document establishing the signatory's authority. For a dwelling, a valid energy performance certificate is required before the mandate is drawn up, which is BRIVEO's own rule, stricter than French law, which only requires it for the listing. The other surveys can wait, the law only requires them for the preliminary contract, and the journey tells you what is missing before publication. The rest of the file is completed later, as a buyer moves forward.
Can I keep advertising my property myself during the mandate?+
It depends on the mandate you sign, and you are the one who picks it. With a simple mandate you keep the right to sell on your own or through any other intermediary, owing BRIVEO nothing. With a semi-exclusive mandate you cannot hand the property to another agency, but you keep the right to look for a buyer by your own means. With an exclusive mandate you undertake not to sell during the term, either directly or through another intermediary. In all three cases you cannot deal with a person BRIVEO introduced to you, during the mandate and for the twelve months following its end.
Buyers & notary
How do you check a buyer's identity and financial standing?+
Identity is verified, financial standing is declared. No offer can be submitted on BRIVEO without a completed identity check, backed by a document, read and then screened against sanctions and politically exposed persons lists, as required by article L.561-5 of the French monetary and financial code. Where the buyer purchases through a company, its entry in the public register and the absence of insolvency proceedings are checked as well. BRIVEO does not, however, check a buyer's income or bank accounts, and issues no proof of funds. The offer you receive states the amount financed by a loan and the conditions attached, and it is the bank and then the notary who test them. A viewing request is not subject to that identity check, which you should know before you open your door.
Can I use BRIVEO's notary once the offer is accepted?+
The notary is chosen by the parties, and BRIVEO imposes none on you. When the offer is accepted, a sale file is opened with the mandate and the documents already uploaded, then passed on. Where BRIVEO has an active partner notary office in the property's département, the file is assigned to it automatically, otherwise the team opens it manually and sends it to the firm you name. BRIVEO drafts neither the preliminary contract nor the deed, both of which are the notary's alone. BRIVEO holds no funds, the deposit is held in escrow at the notary's office, and fees are paid only when the deed is signed.
LAIA, artificial intelligence
What exactly is LAIA?+
LAIA is BRIVEO's AI assistant. It runs on Anthropic's Claude models with a knowledge base assembled by BRIVEO, French real estate law (Hoguet, GDPR, monetary code), DVF transaction data and official sources. It values properties, prepares documents and helps qualify listings.
Can LAIA hallucinate?+
Like any AI, LAIA can make mistakes. It is designed to rely on official sources (cadastre, French tax data, DVF), to cite where a figure comes from, and to say when data is missing rather than invent it. On legal topics its answers are informative, and a human adviser takes over when in doubt.
Can I talk to a human?+
Yes, on Premium you get a dedicated agent, authorised under the carte T of Liberty House Real Estate SAS. On Smart, the LAIA chat 24/7 answers the vast majority of questions. If LAIA cannot answer, your question is forwarded to the Briveo team during business hours.
Valuation
Is the AI valuation free?+
Yes, totally free. No commitment. In 2 minutes you get a high/low range, the price per sq.m and the number of real sales it is based on.
What is the valuation based on?+
On official French gov data (cadastre + property transaction database), up to 10 comparable sales within a 400m adaptive radius, the energy rating you declare, and the 12-month local trend. No subjective estimates.
Is the valuation reliable?+
Each valuation displays a confidence level and a range. The confidence level depends on the number of comparable DVF sales retained within the radius around the property, it is lowered when the available sales are old or when the postal code covers several communes, and it stays indicative in the departments DVF does not cover. The more recent comparable sales an area has, the narrower the range. The full method is published at briveo.fr/methode. The valuation remains indicative and does not replace a survey.
Security & data
Are my documents secure?+
Your documents are encrypted at rest (AES-256-GCM), each with its own key, itself protected by a master key kept outside the database. Access to the documents is limited to authorised BRIVEO staff and to LAIA for reading them, and every consultation is recorded in a chained log (SHA-256) where any alteration is detectable. Your data is never used to train models.
Where is my data hosted?+
Your data is hosted in the European Union, server in France at Hostinger, encrypted backups under EU jurisdiction. Some processing involves subprocessors established in the United States, notably Anthropic's Claude API for document analysis, governed by the 2023/1795 adequacy decision and, as a fallback, by the 2021/914 Standard Contractual Clauses incorporated into their data processing addendum. Your data is never used to train models. Details are in our privacy policy. BRIVEO's data protection contact answers at dpo@briveo.fr.
Can I request data deletion?+
Yes, right to erasure (GDPR art. 17). Form at /droits-rgpd: you receive an acknowledgement carrying your request reference. Response time max 1 month (art. 12), with a reminder to the data protection contact before the deadline and escalation beyond it. Some data is kept 5 years for AML/CFT law or 10 years for Hoguet law (art. 17(3)).
