Aulnay-sous-Bois – Real Estate Investment Overview

About Aulnay-sous-Bois

Aulnay-sous-Bois combines suburban residential scale with direct access to the wider Paris region, making it a closely watched location in Seine-Saint-Denis. Its apartment market reflects a practical balance of local housing stock, commuter links, and changing investment conditions.

In May 2026, the main signal is firmer pricing, but not without a counterweight for investors. The average apartment sale price reached €231,740, while the average asking rent stood at €950. That combination produced a gross yield of 5.81%, showing that income returns remain present even as capital values edge higher.

The tension is clearer in the recent price movement: the average sale price rose 5.3% over the month, the average rent price increased 3.4%, and the average price per square metre climbed 3.3% to €3,817. Yet the year-on-year picture is softer, with sale prices down 3.0%, rents down 4.0%, and the price per square metre down 3.9%. Taken together, these figures suggest a market that has strengthened in the short term, while still sitting below last year’s level. For apartment investors, that means the May 2026 backdrop is one of improving pricing momentum, but with yield and valuation both needing close attention.
