The Parisian real estate market is suffering from competition in the inner suburbs, according to Century 21

The construction of housing on the outskirts of Paris, particularly in Saint-Ouen-sur-Seine and Saint-Denis (Seine-Saint-Denis) for the Olympic Games, is competing with the Parisian real estate market, said Charles Marinakis, president of Century 21, a few days ago, who mentioned a possible drop in prices in the future.

"The housing development zones in Saint-Ouen or Clichy (Hauts-de-Seine, editor's note) are doing a lot of damage to the Parisian market," said the president of the real estate agency network during a press conference.

"Competition has become structured at the gates of Paris and the arrival of new metro lines changes everything," he added.

This is particularly the case in Seine-Saint-Denis, where entire districts have been created in recent years, notably to accommodate the athletes' village for the 2024 Olympics.

In Paris, the number of real estate transactions carried out during the first six months of the year fell by 0,4%, while apartment sales in Île-de-France increased by 1,7%.

For the moment, this supply of cheaper housing on the outskirts of the capital "is not yet weighing on prices, but if transaction volumes continue to fall, this will inevitably have consequences on prices," warns Charles Marinakis.

Since 2019, i.e. before the crisis caused by the rise in rates from 2022, prices in Paris have fallen by 6,9%, to reach 9.483 euros per m³, while they show an increase of 8,7% for apartments in the Ile-de-France region (4.417 euros per m³).

It is primarily investors buying properties to rent out who have turned away from the Parisian market in favor of the suburbs. Their share among buyers in the first half of 2026 fell by 12,2% in Paris and rose by 13,5% in the Île-de-France region.

"Paris has long been considered one of the most resilient markets for wealth investment. At this level, the capital is now falling below the national average and below the level observed in Île-de-France," the real estate specialist points out.

Buyers under 30, who account for one in five transactions in France, have also turned away from expensive markets, such as Paris or Hauts-de-Seine, to favour more affordable areas in Seine-et-Marne, Val-de-Marne or Essonne.
