Value your property for free from transactions actually recorded near you, in a few minutes.
The estimator starts from the price per m² actually recorded in your area (DVF), then adjusts it to your property's characteristics. It relies on no listing or self-declared data.
Address, type, area, condition, floor… in a few guided fields.
Cross-referenced with the DVF transactions of your area, adjusted to your criteria.
A low price, a high price and a reference price per m², instantly.
Our estimator does not stop at a town-wide average. For each address, it selects the sales actually completed around the property in the DVF database (Demandes de valeurs foncières), published by the French tax authorities, and derives a reference price per m² specific to your area.
| Situation | Sales used | Minimum threshold |
|---|---|---|
| Large city split into IRIS zones | Sales in the same INSEE statistical district (IRIS) as your property | 8 sales of the same type |
| Quiet IRIS district | Sales in the town within 500 m to 2 km, excluding prices far from the district median | 12 sales |
| Other towns | Sales within a radius widened in steps, from 300 m to 5 km | 25 sales (at least 8 at 5 km) |
Outlier prices are removed using the quartile method. Each remaining sale is weighted by its distance from your property and its age: a sale from a year ago weighs about 2.7 times less than one from this month. The price used is the weighted median of these sales.
DVF sales are recorded with a lag behind the market. The reference price is therefore adjusted to the change in the Notaires-INSEE index, by property type (flat or house), with one series for Paris and one for the rest of the country.
Finally, this reference price is adjusted to your answers. The coefficients vary with the price level of the area: an older building does not weigh the same way in a sought-after city centre and in a rural village.
The result is a range: from 6% below the central value to 12% above it. The more comparable sales there are near you, the sounder the reference price. In quiet areas, the radius widens and the valuation becomes more indicative.
Moselle, Bas-Rhin, Haut-Rhin and Mayotte are not included in the DVF database, as their sales fall under a separate land registration system. For these areas, the estimator relies on broader references and the result is less precise.
At the same address, two homes can show very different prices per m². The table below shows the effect of each factor and how our estimator accounts for it, with the adjustments the calculation actually applies.
| Factor | Effect on value | In our estimator |
|---|---|---|
| Location | The main price driver, from one street or district to the next | Reference price calculated from nearby sales |
| Floor area | The price per m² falls as floor area rises | From +17% below 30 m² to -10% above 120 m² (reference: 50 to 80 m²) |
| Number of rooms | At equal floor area, the layout changes the price per m² | From +8% (1 room) to -6% (6 rooms or more), flats |
| Condition | Work to be done is deducted from the purchase price | From -25% (needs renovation, rural area) to +15% (new) |
| Construction period | Older buildings are valued in city centres, less so elsewhere | From -8% to +18% depending on period and area |
| Energy rating (DPE) | F and G ratings carry a discount, larger outside major cities | From -25% (G-rated house, rural area) to +14% (A rating) |
| Outdoor space | Balconies, terraces and gardens are in high demand | Loggia +2%, balcony +3%, terrace +5%, garden +6%, combined cap of +8% |
| Floor and lift | Ground floors are discounted, upper floors valued | Ground floor -5 to -12%, upper floors up to +8%, -3% on the 3rd floor or above without a lift |
| View | An open or sea view can justify a clear premium | Not modelled: to be assessed during a visit |
| Parking | Highly sought after in cities, where it is scarce | Garage +4%, outdoor space +2%, shared car park +1%, several spaces +5% |
For a house, the number of storeys (from -1% for single-storey to +2% for three or more) and a swimming pool (+6%) replace the floor factor.
Since 1 January 2025, G-rated homes can no longer be let under a new lease, and F-rated homes will follow in 2028. A buy-to-let purchaser factors this timetable and the cost of the work into their offer.
Every estimate relies on public, official sources, cross-referenced to make the result reliable and comparable from one area to another.
Track the change in your town's prices over twelve months and the number of sales in your district. An active market shortens selling times; a slowing market calls for the right price from day one.
Have the surveys carried out before listing: the energy rating must appear in the advert. Also prepare your title deed, recent property tax notices and, for a flat in a shared building, the minutes of general meetings.
Sale through an estate agent (sole or multiple agency), privately, through a notary or by online notarial auction: each option has its own cost, timescale and level of support.
| Survey | When is it required? |
|---|---|
| Energy performance (DPE) | For every home put up for sale |
| Energy audit | House or single-owner building rated E, F or G |
| Asbestos | Building permit issued before 1 July 1997 |
| Lead | Home built before 1949 |
| Electricity and gas | Installations over 15 years old |
| Risk statement (ERP) | For every property, in every town |
| Termites, dry rot, drainage, noise | Depending on the area or the property's equipment |
| Carrez floor area | Unit in a shared building |
An asking price set too high lengthens the sale and often ends in a price cut. Start from actual sales in your area, then adjust for the strengths and flaws a visit reveals.
You are preparing a sale and looking for the right listing price, without over- or under-pricing it.
You follow the value of your assets as the market moves, district by district.
You are looking for a first reference value for an inheritance or a division.
Yes, estimating a price range is entirely free and without obligation.
A few minutes: the form takes under two minutes and the range appears immediately.
No. Your details (email, phone) are only requested to receive the detailed result and be contacted again if you wish.
From transactions actually recorded (DVF), complemented by the references of the Notaires de France and the indices of INSEE. These are public, official sources.
It gives a reliable market range. The final price then depends on the property's exact condition, view, floor, works and negotiation.
An online valuation such as ours and an estate agent's appraisal are usually free. A report by a chartered surveyor or a notary is paid: fees are set freely on quotation, depending on the property and the purpose of the report.
It helps: two or three opinions give you a price range. Be wary of the highest figure, which may be aimed at winning the listing. Above all, compare the recent sales each agent cites to justify its figure, and check them against the DVF prices in your area.
An online valuation is statistical: it starts from nearby sales, without a visit, and gives a range. An estate agent's appraisal adds a visit, with no legal commitment. A formal appraisal produces a written, reasoned report, useful with the tax authorities for an inheritance, a gift or a divorce.
Our range runs from 6% below the central value to 12% above it. Its reliability depends on the number of comparable sales near you: high in cities, lower in quiet areas where the search radius widens. We do not publish an average error rate, because it varies too much from one area to another for a single figure to be honest.
The DVF database is published by the tax authorities in successive releases. Between releases, an adjustment based on the Notaires-INSEE index brings recorded sale prices closer to current market levels.
It gives a solid starting point, based on real sales. To set the asking price, add a visit that accounts for what no database measures: the view, the light, overlooking buildings, the actual condition of the common areas.
