In 2025, 745 sales were recorded in Montrouge: enough to choose from, never enough for the finest addresses.
The median for apartments has moved -12% since 2021 and 0% over one year: a market correcting, address by address.
Houses trade at a median of €10,700/m² against €7,200/m² for apartments: land and gardens pay for their scarcity.
Montrouge lives the dynamic of every gate town: a €7,200/m² median on flats in 2025, a quarter less than the capital at its doorstep, for commutes comparable to many an Eastern arrondissement. The studios and one-bedroom flats of Vieux Montrouge and the three-bedroom flats of the recent residences form two distinct markets within one town.
After the post-covid fever, the market has found a balance: the median has fallen by about twelve percent since 2021, and correctly priced homes now sell within weeks. Buyers come for line 4, the schools and floor area that the neighbouring 14th no longer offers at these prices.
Two vigilance points shape the hunt: the mixed building stock, old unrenovated blocks beside 2000s residences with different service charges, and the department’s rental taxation, which an investor must factor in before offering. The Montrouge house, rare, trades above €10,000/m².
