Lille is a city where people rent more than they own. According to the INSEE 2023 census, 70.2% of main residences are occupied by tenants and 58.0% of households consist of only one person. This is favourable ground for small units and house shares.
The weight of students largely explains this structure. INSEE counts 44,010 young people aged 18 to 24 in education in the municipality, i.e. 79.5% of this age group, and pupils and students make up 22.7% of 15-64 year olds. Demand renews every year at the start of the academic year, with many newcomers: 65.3% of 15-24 year olds who moved home during the year came from another municipality, according to INSEE.
The rent map from the Ministry of Housing and the ANIL gives an advertised rent of about €18.1 per m² including charges for an apartment of 1 or 2 rooms, compared with €14.6 for a 3-room or larger one. In Lille, these advertised rents remain subject to the ceiling set by rent control, which may be lower depending on the address and the year of construction.
On prices, the market is stable to slightly falling. Sales recorded in DVF show an average apartment price per m² down 1.2% between July 2025 and June 2026 compared with the previous twelve months, with 2,571 apartments sold. This volume is enough to resell a standard property without excessive delay, provided it is priced at the market level.
Vacancy reaches 8.0% of homes according to INSEE. This overall rate includes run-down older homes or homes under renovation; a renovated, well-served property at the right rent generally lets quickly in such a student city.
