Despite a still segmented real estate market, several Île-de-France territories displayed a renewed interest in 2025. Here are five areas deemed strategic by experts to invest this year.
After finally stabilized in the 4th quarter of 2024, the real estate market resumed colors in the 1st quarter of 2025; Although in a still fragile and uncertain context. In Île-de-France, sales of old housing rebounded by 21 %, with around 5,000 additional transactions in the first quarter compared to the same period last year. But the economic, geopolitical and financial environment remains unstable, and these first signs of recovery could be called into question in the short term.
The restart is particularly visible in certain municipalities of the small and the large crown, where prices start upwards in a differentiated manner according to the profiles of territories.
Crown
In the small crown, municipalities like Boulogne-Billancourt and Levallois-Perret continue to stand out, with a slight increase in prices. The direct proximity of these cities to the capital, combined with good public transport, makes them very attractive for executives, families and investors. With little available land, the tension on the offer is maintained, supporting high prices at the same time.
“The prices of apartments in these areas remained relatively stable in the first quarter of 2025, around € 4,900/m²”note the report of the notaries of Greater Paris.
And the 4 % increase expected in the summer has partially confirmed. In Levallois-Perret, prices exceed € 10,000/m² (+7 % over a year), while in Boulogne-Billancourt, they reach around € 8,070/m², according to better agents.
Large crown
In large crown, the market rebound is even more marked, with a 26% increase in sales. In cities like Saint-Germain-en-Laye, Versailles, and other municipalities in Yvelines or Val-d’Oise, the request remains supported by a clientele seeking to reconcile a pleasant living environment and accessibility to the job centers. On average, prices are 2 to 4 times lower than in very central areas, which allows first-time buyers to become owners.
“The Neuilly market is doing very well, especially for houses with garden”observes Charles-Marie Jottras, president of Daniel Féau Conseil Immobilier, citing a leap of more than 50 % of sales beyond 4 million euros in 2024.
Neuilly-sur-Seine is not part of the large administratively crown, but its high-end market follows a comparable peripheral logic. The municipalities of the heart of the Grande Couronne, on the other hand, display a significant progression. In July 2025, the average price of apartments was estimated at € 3,200/m², up +4.9 % over one year.
Hauts-de-Seine Nord and Yvelines Nord
The North of Hauts-de-Seine (Asnières, Colombes or Gennevilliers) and the North of Yvelines (Poissy, Achères, Carrières-sous-Poissy, etc.) also record a notable recovery. This dynamic is explained in particular by the presence of new Greater Paris stations in these areas. But also from proximity to large employment areas that are Defense, Nanterre or Saint-Denis. The arrival of middle and upper classes, teachers, engineers and young families boosts demand and social revaluation, in cities formerly deemed to be “popular”.
“The municipalities around Asnières and Rueil are experiencing a strong recovery, supported by a drop in prices and a sustained demand from Parisians”details Richard Tzipine, Managing Director of Barnes.
In July 2025, average prices in Asnières reach € 6,200/m² (+3 % over one year), and Colombes € 5,590/m². These levels remain competitive with regard to equipment, access to transport and the medium-term added value.
Thiais and Chevilly-Larue
Zones of the large crown such as Thiais and Chevilly-Larue, also benefit from the extension of line 14, which makes them more accessible from central economic poles. Although the impact on prices is still moderate, these areas should see their prices gradually increase as connectivity improves. These municipalities, long considered to be secondary, are experiencing a real rebound thanks to major transformations linked to infrastructure, urban planning and their strategic position. Thiais and Chevilly-Larue will also be connected to the future line 15 South by 2026. They are in 2025 what Villejuif or Montreuil were in 2010: municipalities in rapid transition, doped by transport and development. In addition, the more we move away from the centers, the more the share of powerful housing energetically in sales increases.
“In large crown, where the park is generally more recent, the share of energy -consuming housing stands as the lowest in the region (15.0%)”note the report of the notaries of Greater Paris.
The average prices in these municipalities remain accessible, oscillating between 3,000 and 4,000 €/m², with a strong revaluation potential linked to the “Grand Paris Express” effect.
