Buying Now Beats Renting in Several Montparnasse Suburbs, Data Shows

Banks and notaires across southern Montparnasse are seeing a surge in first-home buyers as new analysis shows monthly mortgage repayments for certain apartments have dipped below comparable rents in nearby suburbs. Montrouge and Malakoff, both in the southern arc of the 14th arrondissement, now top the list of districts where home ownership has become financially preferable to leasing for many residents.

This shift matters for thousands of Montparnasse renters facing the sharpest rental price increases since 2022. The rise is fuelled by swelling demand from professionals looking for proximity to Paris’ left bank tech corridors, notably around Rue de la Gaîté and the modern developments near Tour Montparnasse. Meanwhile, inflation-linked rent adjustments and a limited pool of well-kept properties have pushed average rents in certain blocks to over €1,800 per month for two-bedroom units.

Where Buying Now Wins

Concrete listings compiled by Agence Varenne and recent records from Notaires de Paris show two-bedroom flats near Avenue Pierre Brossolette in Montrouge selling for around €420,000. With current fixed-rate home loans sitting at 3.3% according to Crédit Agricole’s July bulletin, a typical buyer with a 15% deposit now pays about €1,626 per month in mortgage outgoings-well below the area’s 2026 median rent of approximately €1,850 for equivalent units. In Malakoff, where a similar flat on Rue Gabriel Crié is listed at €395,000, monthly repayments hover near €1,530, compared to rents above €1,700 monthly.

Local buyers cite proximity to the Ligne 13 Métro and Parc Montsouris as major attractions, with many first-time owners targeting former mid-century apartment blocks that are now prime for renovation. Comparing these suburbs to central Montparnasse or the ever-popular Rue du Départ, ownership remains out of reach there, with asking prices above €12,000 per square metre and average rents only marginally cheaper than local mortgage estimates.

Price Pressures and What Next

Data from SeLoger, published in June, reported a 4.6% annual rise in rents for the Paris inner ring, with Montparnasse jumping even higher year-on-year. Meanwhile, sellers in Montrouge and Malakoff have cut listing prices by up to 7% since the winter peak, according to the quarterly review from the Chambre des Notaires de Paris. Buyers leveraging this window are already seeing more value in ownership than rental, especially with signs that mortgage rates may remain stable through year-end.

Practical advice for those weighing the switch: scrutinise notarie fees and monthly co-propriété charges, which can add several hundred euros to ownership costs. Yet, for many residents of Place de Catalogne now recalculating their budgets, Montparnasse’s southern suburbs have quietly become the affordable entry point for buyers-at least until the next rental surge or interest rate jump. Market watchers from Montparnasse Immo predict continued buyer interest in these neighbourhoods through the autumn, urging renters to compare offers closely before renewing another year’s lease.
