Buying in Roquebrune-Cap-Martin: a neighbourhood guide from someone who lives here

Roquebrune-Cap-Martin is where I'm based. It sits between Menton and Monaco, and the town spans very different worlds within a few kilometres: a medieval hilltop village, the villas of the Cap-Martin peninsula, the busy town centre of Carnolès along the beach and the railway, and quieter residential valleys inland. Prices vary just as much. Here is a practical overview of each area, with the latest figures and the one big project that will reshape the town over the next few years.

What it costs: two ways of measuring

To understand prices here, you need to look at two kinds of figures.

Market estimates. According to Meilleurs Agents estimates as of 1 August 2026, reported by Menton-Presse, the average is about €6,730/m² for an apartment and €12,735/m² for a house, or close to €7,800/m² for all property types. Those averages hide a wide range, from about €3,700 to over €25,000/m² depending on the address, the view and the condition. The same source says values have risen 28% over ten years, dropped by more than 2% over the latest three months and been flat over one year.

Actual sales. On my Market prices page, based on the notaries' register (DVF), the median apartment price in Roquebrune-Cap-Martin was €6,187/m² in 2025, based on 450 sales, up 26% since 2014. The provisional figure for the first half of 2026 is €6,591/m². For houses, the 2025 median was €10,474/m².

The gap between those two sets of figures is normal: estimates follow asking prices and the best properties, while DVF records what buyers actually paid. When I value a property, I start from real sales on the same street and in the same type of building, then adjust for view, floor, parking and outdoor space. Those details matter more here than almost anywhere else on the coast.

Cap-Martin and the seafront: the top of the market

The peninsula and the seafront are the most expensive part of town. According to the same August 2026 estimates, houses on Cap-Martin reach up to about €12,677/m², and apartments are above €7,100/m². Cabbé–Saint-Roman, which faces Monaco, has the town's most expensive apartments, at around €8,373/m². The most sought-after streets (avenue Princesse-Grace, avenue du Président-Kennedy, avenue des Genêts) are above €9,100/m².

What you pay for: the sea, the light, and being minutes from Monaco. What to check: parking (often scarce), the condition of the residence and its co-ownership charges, and whether a "sea view" is a panorama or just a glimpse.

Carnolès: the town centre, and the most accessible prices by the sea

Carnolès is the urban heart of Roquebrune-Cap-Martin, next to Menton, with shops, the beach and Carnolès railway station. Meilleurs Agents puts the average apartment at around €6,037/m² here (August 2026). On some streets, such as avenue de Verdun, avenue du Danemark and avenue Jean-Monnet, prices drop to just over €6,000/m², the lowest level in town.

Carnolès is also where the town's biggest change is happening: Cœur de Carnolès. The project turns the former Air Base 943, a 3-hectare military site closed in 2012, into a new neighbourhood, to be completed around 2030 according to the town hall (some press reports 2032). The town hall's plans include:

• 363 homes, including 150 social-housing units, with the others split between homes sold at controlled prices (accession maîtrisée) and homes sold on the open market;
• a new school for 420 pupils, due to open in September 2027;
• a landscaped park of about 5,400 m² and more than 7,000 m² of green space in total;
• more than 3,500 m² of local shops, about 1,300 m² of offices and a cultural centre;
• a target of 80% renewable energy (geothermal and solar);
• studies with SNCF Réseau to modernise Carnolès station, and a planned 400-space park-and-ride a few metres from it.

On 1 July 2026, the Prefect of the Alpes-Maritimes visited the site and praised it as an example of "building the city on the city", meaning reusing land that is already built on. For buyers, a large, well-planned project usually helps the surrounding streets in the long run, with more services, a new school and better transport links. In the meantime, expect a few years of building works. The open-market homes are sold through the project's information and sales office at 47 avenue Robert Schuman.

The village and the hillsides

The medieval village of Roquebrune, perched above the bay, is around €6,700/m² for apartments (August 2026 estimates for the Cros-de-Casté–Mont-Gros sector). Expect character, steps and views. Parking and access deserve as much attention as the floor plan. Inland, Val de Gorbio has the lowest average in town, at around €5,803/m² for apartments.

The town also has a unique piece of heritage. Le Corbusier's Cabanon, a 14 m² cabin on the coast, is listed as a UNESCO World Heritage site. The town celebrated the 10th anniversary of the listing in July 2026.

How the market works here

Two points from local reporting match what I see every day. Monaco next door creates constant demand. And many sales happen privately, through personal networks, and never appear on public listing sites. Mid-sized apartments often sell to cash buyers such as retirees or second-home owners. For comparison, Menton is noticeably cheaper, at around €5,200/m² for an apartment according to the same source.

In practice, buyers who are well prepared (financing ready, a clear brief, quick to visit) get the best opportunities. Because I'm also an investor and have managed renovations and rentals myself, I look at every property in terms of its potential, its true costs and its rental prospects, not just its view. If a holiday let is part of your plan, check the local rules first: Nice, for example, now caps new permits in its most popular districts, as I explain in my guide to the 2026 holiday-let rules in Nice. Through my partner agencies, I can also widen a search to Monaco and western Liguria.
