After a decline in prices in recent years, since 2025 there has been a noticeable return of demand, particularly for single-family homes, which are rare in the municipality and command particularly high values with strong demand. This trend is also seen in properties located in the most desirable neighborhoods, such as Silly-Gallieni, Parchamp–Albert Kahn, and Prince–Marmottan.

This attractiveness is explained by the sought-after living environment, with its immediate proximity to Paris and its well-developed transport network, which continues to draw families and investors.
Adding to this are major structural projects, including the opening in early 2026 of the departmental public garden on Île Seguin, which will become a new green lung for the city, and the planned inauguration at the end of 2026 of Pointe des Arts, which will house a cinema, the Emerige Foundation, as well as office spaces, further enhancing Boulogne-Billancourt’s cultural and economic appeal.

According to projections, property prices in Boulogne-Billancourt could start rising again in 2026, with an expected increase of around +2% to +5% if demand remains steady. Some market analyses also indicate a stronger growth for single-family homes due to the scarcity of supply.
The neighborhoods of Prince-Marmottan, the city center, and Point-du-Jour/Jean-Jaurès continue to be among the most sought-after, often with prices above the average, reflecting their quality of life and accessibility.

With these prospects and the attractive local context, Boulogne-Billancourt confirms its status as a safe bet for a purchase or investment project in 2026.
