Archived IMMO BTC reviews: local DVF 2025 snapshot methodology

DGFiP / Etalab open data, ordinary sales (Vente). Records are selected with ratios between EUR 500 and EUR 25,000/m². Filtering is at property-row level; a sale may contain several properties. Record counts therefore differ from exact sale counts. Values outside the range, including the most expensive properties, are excluded. Results describe the sample without adjustment for quality or property mix. The new 2024–2025 comparison uses a stricter selection of one apartment or house per sale: results from these two methods should not be joined directly into a time series.
