This is not exactly another list of cities in which to invest in real estate in Greater Paris. Nor is it Ile-de-France’s arrangement of towns and villages in France where life is good. The observatory just unveiled by the National Union of Real Estate Agents of Greater Paris on the real estate attractiveness of nearly 300 cities in Greater Paris* is an unprecedented observatory.
Admittedly, the tool traditionally bypasses data on real estate prices. But, the new fact, that it passes each city through a sieve 11 additional criteria on the basis of data that makes it possible to measure its attractiveness. These data are objective and non-qualitative, identified by the authors of the observatory and issued from official sources (ANSI, ministries, town hall statistics, etc.).
Olivier Principal, Vice President of Fnaim du Grand Paris, commented that the aim of this new observatory is to provide a tool based on rating criteria for each major Paris municipality to identify them, according to the expectations of future buyers or renters. Good to live and easy to buy to settle there. »
In terms of methodology, the 12 criteria used are: housing price, quality (rate of central heating equipment, age and space of dwelling, etc.), security (physical violence, property damage, criminality… .), and health (number of medical practitioners per 100 inhabitants). , number of hospital beds per square kilometer, etc.), education (nurseries, colleges, high schools, etc.), public transportation (metro, RER, bus, travel time to home/work, etc., environment ( The area of green space per inhabitant, changes in car use, etc.), commerce (number of shops every 100 meters, etc.), employment (unemployment rate, etc.), culture (museums, theaters, stadiums, gyms, etc.) it), income and finally local taxes (housing and property taxes).
Interactive multi-parameter map
Each criterion is assigned a score from 1 to 10, which is then weighted by a factor. It should be noted that to determine the price of the property, the observatory relies on the average price of housing for each municipality. This is determined by multiplying the price per square meter by the average housing area for residential use in each city. “It avoids the predicament of offering a price per square meter that is not the average purchase or average value of goods in the city,” the observatory notes.
With regard to the cities chosen, and for Paris, each arrondissement is considered as a city in itself. Moreover, for the entire arrangement, the price factor was isolated from the standards in order to understand its impact and its connection with the municipality’s attractiveness. Thanks to the interactive map already available on the Internet, you can search for a municipality with or without housing prices, by attractiveness criterion or by combining three of twelve criteria. The map also shows the real estate agencies that are members of La Fnaim du Grand Paris (www.fnaim-grand-paris.fr) and makes public transport lines (metro and RER) visible.
Villages with character in 91 and 78
The index’s original construction mixes the energies of major Paris cities that traditionally top this type of ranking on the real estate’s allure. In the top twenty observatories, which ranked cities by housing price and without housing price, the big winners were fairly small towns, often themed villages, located in the second ring. Parisian (see illustration).

Thus, Milly-la-Forêt, in Essonne, in the Gâtinais Regional Natural Park, won the Palme d’Or with the best score out of 297 cities in the ranking with real estate price. It is still in third place if we exclude the price criterion. Similarly, Boigneville, another themed village in Essonne, ranks third, while in Yvelines, the charming village of Montfort-l’Amaury ranks fifth.e A place in the top 20. Note, in the category of megacities, the good score of Versailles, 5 out of 20, in the ranking without prices, it is still in the top 20 but in 17th place, if we take into account the price criterion.

Parisian areas, such as 6, 8, 5, 9, 2, 3 and 4, are very well represented when the housing price criterion is not included. It should be noted that they are often punished with the criterion of “safety” due to the number of complaints in areas frequented by tourists (museums, etc.).
