France Property Valuation & Sold Prices (DVF) – AVM API

How much is this apartment or house in France worth? Give an address and the living area – get an automated valuation based on official sale prices from notarial deeds (DVF) nearby, with a value range, a confidence level and the comparable sales used. Or ask for a market report for any address, commune or postcode.

The data comes from DVF – Demandes de valeurs foncières, the register of property sales recorded by the French tax administration (DGFiP) from notarial deeds, in the geolocated version published by Etalab. Addresses are located with the official IGN Géoplateforme (Base Adresse Nationale).

What you get

Valuation (one record per property):

• estimated value in € and price per m², with a range (25th–75th percentile of similar sales)
• confidence (high / medium / low) and the number of comparable sales used
• the 10 most similar sales: date, price, area, rooms, price per m², street and number, distance
• the local market: median price per m² within 500 m, sales per year, year-on-year change
• the price level date – DVF is published twice a year, so every result says which quarter it reflects

Market report (one record per area): number of sales, median and quartiles of the price per m² for apartments and houses, prices by number of rooms and by year, year-on-year change, share of new builds – for a radius around an address or a whole commune (Paris, Lyon and Marseille arrondissements included). Optionally the list of individual sales.

Value many properties at once

Put up to 100 properties in properties:

{
  "properties": [
    { "address": "25 cours de l'Intendance, Bordeaux", "areaM2": 80, "rooms": 3 },
    { "address": "8 boulevard Carnot, Toulouse", "areaM2": 62, "rooms": 3 },
    { "address": "10 rue Camille Goillot, Mérignac", "areaM2": 110, "rooms": 5, "propertyType": "house" }
  ]
}

Each successful valuation is a separate record and charge; addresses that cannot be valued get an error record and are not charged.

Use it from an AI assistant (MCP)

Connect the Apify MCP server to Claude, ChatGPT, Cursor or your own agent and ask, for example: "What is a 45 m² two-room flat at 12 rue de la Roquette in Paris worth, based on DVF sales?" The assistant calls this Actor and answers with the estimate, the range and the comparable sales.

How the estimate is calculated

1. Comparable sales – DVF sales of a single apartment or a single house (outbuildings such as a cellar or parking allowed) within 300 m, extended to 700 m, 1.5 km, 3 km or 8 km when there are too few; the last 36 months of data by default. Exchanges, auctions, sales of several dwellings at once and sales including commercial premises are excluded, as are implausible prices.
2. Time adjustment – each sale is moved to the price level of the newest quarter in DVF with the local quarterly trend (smoothed, at most ±15%).
3. Similarity weights – distance, living area (±30% weighs most), number of rooms and recency.
4. Estimate – the weighted median price per m² × your living area; the range is the weighted 25th–75th percentile.
5. Confidence – high with many consistent sales; lower when sales are few, prices vary a lot, or only the street or the commune of the address was found.

This is an automated valuation model (AVM), not a formal appraisal. It does not see the condition, floor, view or energy rating (DPE) of the property – the range shows how much similar properties differ. DVF uses the built area from the land registry (surface réelle bâtie), which can differ slightly from the Carrez area in listings.
