Boulogne-Billancourt, a preferred relocation market for Parisian upper-middle-class families

Overview of the Boulogne-Billancourt real estate market

The Boulogne-Billancourt real estate market has established itself for more than a decade as a preferred relocation destination for Parisian upper-middle-class families seeking more space, long-term stability and a higher quality of life. Directly adjoining Paris’s 16th arrondissement, the city benefits from a structural trend: a gradual residential exodus from inner Paris, estimated at nearly 120,000 residents over the past ten years, largely made up of family households.

Crossing the ring road is no longer a break, but a residential continuation. Once this long-perceived psychological threshold has been passed, Boulogne-Billancourt becomes, for many buyers, a long-term place to settle.

A deliberate and lasting lifestyle shift

“Once the psychological barrier of the ring road is overcome, new residents tend to stay for twenty years,” notes Arnaud Lewandowski of Paris Ouest Sotheby’s International Realty. This average holding period, significantly longer than that observed in inner Paris, is a strong indicator of the family-oriented real estate market in Boulogne-Billancourt .

With 121,500 inhabitants, the city offers a rare balance between urban density and everyday comfort. Families benefit from a smoother daily organisation without sacrificing immediate proximity to Paris. The urban fabric, largely made up of late Haussmannian buildings, Art Deco residences and high-quality contemporary developments, perfectly meets the expectations of a demanding, high-income clientele.

Infrastructure designed for family living

The attractiveness of Boulogne-Billancourt is built on solid and measurable fundamentals. The city records a 73% satisfaction rate for childcare requests, compared with just 16% in Paris, a decisive factor in residential decisions for young families.

Additional strengths include:

• a dense and well-regarded school network, both public and private,
• a strong local retail offering organised around several commercial hubs,
• excellent transport connections via Metro lines 9 and 10, and by 2026, the Grand Paris Express Line 15,
• more than 33 hectares of green spaces, including immediate access to the Bois de Boulogne.

These factors explain why, upon the arrival of a second child, many Parisian families proactively plan a move to Boulogne-Billancourt rather than to other neighbouring municipalities.

A residential stock aligned with upper-middle-class expectations

The housing stock in Boulogne-Billancourt is characterised by a strong predominance of large family apartments. Properties ranging from 90 to 140 square metres, with three or four bedrooms, represent the core of demand. Buildings dating from the 1930s to the 1970s, often equipped with lifts, parking facilities and efficient layouts, align perfectly with contemporary living standards.

In 2025, the average price per square metre ranges between €9,500 and €11,500, with peaks above €13,000 per square metre for exceptional properties located near the Bois de Boulogne or in highly sought-after neighbourhoods such as Prince-Marmottan and Parchamp-Albert Kahn.

This pricing structure remains below that of Paris’s 16th arrondissement , while offering larger floor areas and better functionality, reinforcing the market’s appeal.

A relocation logic, not a fallback option

Unlike certain municipalities perceived as fallback markets, Boulogne-Billancourt follows a high-end residential continuity logic. Families are not leaving Paris due to financial constraints, but as a strategic lifestyle choice. They are seeking a functional upgrade: more space, greater calm and better services.

This dynamic explains the resilience of the market, even during adjustment phases. In 2024 and 2025, while some Parisian segments experienced a marked slowdown, Boulogne-Billancourt maintained high liquidity for well-positioned family properties, with controlled selling periods when pricing remained consistent with market realities.

A secure market for long-term buyers

Buyer profiles in Boulogne-Billancourt are largely composed of senior executives, professionals and entrepreneurs, with strong equity positions. This structure limits the impact of interest-rate fluctuations and contributes to overall price stability.

Low turnover, driven by long holding periods, creates a structural supply tension. Each high-quality property entering the market attracts immediate interest, particularly family apartments with outdoor space or top-floor units offering open views.

Local expertise has become essential

In this context, working with an agency that has a deep, local understanding of the Boulogne-Billancourt real estate market is critical. Valuation cannot be reduced to an average price per square metre. It must take into account the building, floor level, orientation, family layout and the micro-dynamics of each neighbourhood.

This tailored approach is now the key to securing transactions, for both sellers and buyers, in a market that has become increasingly selective.
