Several key factors influence real estate prices in Boulogne-Billancourt, a suburb located just southwest of Paris. The proximity to the capital plays a significant role; properties within a 10-minute walk from the Metro or RER stations can command prices upward of €6,000 per square meter, while those further away may drop to around €4,500 per square meter. The neighborhood's appeal is enhanced by its green spaces, such as the Parc de Billancourt and the Seine’s banks, which attract families and promote higher property values. Additionally, the presence of quality schools and services contributes to demand, with areas near the Lycée Louis de Broglie seeing price premiums. Economic factors, such as the increasing popularity of remote work, have also impacted the market; properties with home office potential have observed a price surge of about 10% over the last year. Finally, ongoing developments, including the Grand Paris Express project, promise improved transport links, further driving interest and speculation on real estate values.
