Mood illustration of Éragny, a municipality of the Cergy-Pontoise new town, in the Val-d'Oise.
The average apartment price in Éragny stands at 3 072 €/m², according to the sales actually recorded in the DVF database, which lists the transactions completed before notaries. That level remains moderate on the scale of the Val-d'Oise and the Paris region, within the range of the municipalities of the Cergy-Pontoise new town to which Éragny belongs. The stock combines developments of the 1970s and 1980s born with the new agglomeration, more recent small blocks, and the detached houses of the old village clinging to its knoll. The storey, the aspect, the presence of a balcony or a parking space, the general condition and the energy performance explain most of the gaps from one dwelling to another. Closeness to the RER station and to the banks of the Oise also weighs on value. These figures, drawn from sales signed before notaries, give a reliable municipal benchmark; a precise valuation then rests on comparable sales, examined property by property.

The Éragny market is carried by Paris-region residential demand looking for prices more affordable than in the neighbouring Yvelines or in the best-rated municipalities of the Val-d'Oise. Families and first-time buyers make up the bulk of purchasers, drawn by the rail service and by the setting offered by the banks of the Oise. Energy performance is establishing itself as a bargaining factor, in particular on the dwellings of the first decades of the new town.
Belonging to the Cergy-Pontoise agglomeration is the main driver of value in the medium term, with its employment centres, its universities and its development schemes. For a seller, a property correctly valued and presented, close to the station or recently renovated, stands out clearly on this fallback market. An over-ambitious price, conversely, settles in for the long haul without finding a buyer.
Éragny sits in a price range close to that of Cergy and Pontoise, the cores of the new town, and of Conflans-Sainte-Honorine, its neighbour in the Yvelines on the other side of the Oise.
Until the 20th century, Éragny was only a modest village perched on a hillside overlooking the Oise, home to fewer than five hundred inhabitants who lived mainly from farming and market gardening. The arrival of the railway made it possible to work a limestone quarry that had until then served only local needs. The writer Bernardin de Saint-Pierre, author of Paul et Virginie and a disciple of Rousseau, stayed for a time in the village's former presbytery.
The face of the municipality changed from the end of the 1960s, with the creation of the Cergy-Pontoise new town, intended to organise the growth of the western Paris region. Éragny was attached to it and its population rose sharply within a few decades, carried by new residential districts, public facilities and business parks. The municipality then adopted the working name of Éragny-sur-Oise.
Today, Éragny keeps the trace of that double inheritance. The old village and its church sit next to the developments born of the new town, while the banks of the Oise and the leisure park close by offer green breathing space. The municipality relies on its rail service towards Paris and on its integration into the Cergy-Pontoise agglomeration.
Éragny has a little more than 18 000 inhabitants and attracts first of all families and working households employed in the Cergy-Pontoise agglomeration or reaching Paris by RER. First-time buyers find apartments there that are more affordable than in the neighbouring municipalities of the Yvelines, while the detached housing stock appeals to households looking for a house with a garden without leaving the inner ring. Rental demand is supported by the presence of young working people close to the employment centres of the new town.
The average apartment price in Éragny is 3 072 €/m², according to the DVF transactions actually completed before notaries. That average covers varied situations, from the older dwelling of the old village to the apartment in the districts of the new town. The storey, the general condition, the energy performance, the presence of a balcony or a parking space and closeness to the station explain the gaps around this value. A reliable valuation rests on comparable sales rather than on the municipal average alone.
Yes. Éragny is one of the municipalities of the Cergy-Pontoise agglomeration, the new town created at the end of the 1960s to organise the development of the western Paris region. That attachment explains the presence of residential districts and public facilities built from the 1970s onwards, alongside the old village. It weighs on the property market by supporting demand from working households and families close to the employment centres of the agglomeration.
Éragny is served by the RER and by the suburban lines that link the Oise valley to Paris and to La Défense, as well as by the major roads of the western Paris region. That accessibility makes it a residential municipality for working people employed in the capital or in the Cergy-Pontoise agglomeration. Closeness to a station and the quality of the service are among the criteria that most influence prices from one sector to another.
The Éragny stock mixes apartments in the small blocks born with the new town, more recent schemes, and town houses or detached houses, notably around the old village. Buyers find there both floor areas suited to a first purchase and family houses with a garden. The type of property, its condition and its location in relation to the station and to the banks of the Oise largely determine its price.
