This little -known method allows you to know which houses will be sold even before they appear on real estate ad sites. And it’s totally legal.
Knowing that a property will be put up for sale even before it appears on the ad sites could be clairvoyance. However, there is a perfectly legal method for anticipating future sales in your neighborhood or your municipality, and it is based on administrative data accessible to all.
This technique is based on a regulatory obligation: when an owner wishes to sell or rent his property, he must have an energy performance diagnosis (DPE). This document, made compulsory by law since 2006 for sales and 2007 for rentals, assesses the energy consumption and the environmental impact of housing through two labels ranging from A (very efficient) to G (very energy -consuming).
Once the DPE has been carried out by a professional, the diagnosis must be transmitted to the Environment and Energy Management Agency (ADEME), a public body responsible for ecological transition. ADEME then attributes a 13 -digit identification number which must appear on the DPE to make it valid.
This is where the trick resides: Ademe publishes all the DPEs made in a database called “DPE data”, accessible free online. This colossal database contains more than ten million diagnoses available by all. By filtering this information by date and by location, it then becomes possible to identify the goods which have recently been the subject of a DPE in your sector, and which are therefore likely to arrive on the real estate market soon.
The richness of the available information is impressive: precise address, energy class, housing area, construction year, but also much more specific details. For an apartment, you can even know the floor and the position on the landing. Regarding the technical characteristics, the dataset specifies the energy used, the quality of the insulation, the type of heating, and all the criteria used to determine the energy classification of the property.
In parallel, ADEME also publishes data from energy audits. Unlike the DPE which is a simple observation of energy performance at an instant T, the energy audit goes further by proposing an in -depth study of the building and the recommendations of work to improve this performance. This second database is even more detailed than that of DPEs, providing an even more complete vision of goods likely to arrive on the market.
