Menton and Roquebrune-Cap-Martin Property Market Guide

The average asking price for an apartment across Menton and Roquebrune-Cap-Martin reached €7,937.6/m² in Q3 2026 on CASAFARI Area Insights, up 4.8% on a year earlier and 17.0% since Q1 2023 without a single down quarter. Houses ask around €13,097.5/m² across a small, volatile sample. Monaco next door, a housing stock that is almost 45% second homes, and almost no buildable land explain the premium: these are asking prices from listings rather than completed sales, sitting well above the €4,880/m² notarial median for older apartments across the Alpes-Maritimes.

Step off the 07:52 TER train from Monaco at Menton or Carnolès on a Tuesday morning and you see the market in motion: cross-border bankers and hospitality staff heading home from shifts in the Principality, passing couples from Turin or Milan who have come across the border to view a two-bedroom flat with a balcony over the bay. On this final stretch of the French coast, local wage earners and international wealth compete for the same narrow strip of property.

Where exactly are Menton and Roquebrune-Cap-Martin, and why does Monaco matter so much?

Roquebrune-Cap-Martin shares its western border directly with the Principality of Monaco, while Menton touches the Italian border to the east, just one train stop from Ventimiglia. Together they form a steep coastal amphitheatre divided into distinct micro-markets: the historic Menton old town and seafront, the sheltered bay of Garavan, the residential blocks of Carnolès, the pine-covered peninsula of Cap Martin, the perched medieval Roquebrune village, and the border quarters of Saint-Roman and Cabbé.

Monaco's labour market is the primary engine of local housing demand. According to the IMSEE employment observatory 2024 (published April 2025), roughly 90% of Monaco's private-sector workforce commutes in from outside the Principality, with 48,235 workers living in France. Menton alone is home to 7,351 of those private-sector employees—12.4% of the total and second only to Nice. In the hotel and restaurant sector, IMSEE's June 2026 report notes that Menton hosts 15.6% of France-resident staff, while Roquebrune-Cap-Martin houses 10.7% of those living in the immediate neighbouring communes.

This commuter pressure meets a demographic structure shaped by leisure and retirement. According to INSEE figures for the commune of Menton from the 2023 census (published in 2026), Menton has 30,604 inhabitants, growing by 0.9% a year between 2017 and 2023 entirely through net in-migration (+1.6% a year) against a negative natural balance (-0.7%). Next door, INSEE figures for Roquebrune-Cap-Martin record 12,037 inhabitants in 2023.

What do homes cost in Menton and Roquebrune-Cap-Martin in 2026?

In Q3 2026, the average asking price for an apartment across Menton and Roquebrune-Cap-Martin combined stood at €7,937.6/m² (excluding statistical outliers), according to the Area Insights price series for any French commune. That level reflects active listings across both communes, blending functional flats in Carnolès with seafront residences in Garavan and Saint-Roman.

Houses and villas sit in a different bracket altogether. In Q3 2026, the average asking price for houses across the two communes reached €13,097.5/m² on CASAFARI Area Insights, or 1.65 times the apartment figure. Because villas on Cap Martin, in Garavan and on the Roquebrune hillside represent a tiny fraction of the stock, the quarterly house average moves sharply whenever one or two high-value properties enter or leave the market. In Q2 2026, the house average dipped to €11,795.2/m² (down from €12,894.0/m² in Q1 2026) before rebounding to €13,097.5/m² in Q3 2026. That swing is a composition artefact caused by the mix of listings, not a sudden drop and recovery in underlying land values.

It is essential to distinguish between asking prices and completed sales. CASAFARI figures track what sellers and agents ask on listings in real time; notarial databases record completed deeds months later. Across the wider Alpes-Maritimes department, the Alpes-Maritimes notarial price report (Chambre des notaires des Alpes-Maritimes / PERVAL, covering the 12 months to October 2026) puts the median completed transaction price for older apartments at €4,880/m², with a median sale price of €230,300 for a 52 m² flat. Even allowing for the negotiation gap between asking and signing, Menton and Roquebrune-Cap-Martin trade at a substantial premium to the department. Because averages hide wide street-by-street variations, advisers typically value a specific flat or villa with Comparables before submitting an offer.

How fast are prices rising compared with the rest of the Riviera and France?

While much of the French residential market spent 2023 to 2026 adjusting to higher borrowing costs, this corner of the Riviera kept climbing. On CASAFARI Area Insights, apartment asking prices in Menton and Roquebrune-Cap-Martin rose 4.8% year on year in Q3 2026 (up from €7,576.3/m² in Q3 2025) and 17.0% between Q1 2023 (€6,785.8/m²) and Q3 2026. Over those 15 consecutive quarters, the apartment series did not record a single quarterly decline.

Over the same 15-quarter window from Q1 2023 to Q3 2026, house asking prices rose 15.6% (from €11,330.6/m² to €13,097.5/m², and +3.1% year on year against €12,704.3/m² in Q3 2025), a slightly slower cumulative pace than apartments once indexed to Q1 2023 = 100.

France Existing Homes (Sales)	~949,000 sales	+0.2%	Notaires de France, Q1 / May 2026

Comparing these asking-price trends with completed sales across the region and the country highlights both the resilience of the border strip and the need for caution. In the Alpes-Maritimes, completed apartment prices rose 2.4% over the year to October 2026, while departmental transaction volumes for older apartments slipped 4.3% to 18,318 sales in the 12 months to July 2026 (down from 19,133 a year earlier, per the Chambre des notaires). Nationally, the Notaires de France market note shows existing-home prices quasi-stable at +0.2% year on year in Q1 2026 across roughly 949,000 annual transactions to end May 2026. You can compare how the departmental capital has performed over the same cycle in our guide to the Nice property market and across the country in our France property market guide.

Who is buying here, and what are they looking for?

Because the housing stock in Menton is overwhelmingly vertical—89.6% apartments (26,229 dwellings) against just 9.7% houses (2,848 dwellings) in the 2020 INSEE census—apartments dictate the rhythm of the market. Nearly half of all properties across the two communes are not occupied year-round: INSEE's 2023 census shows that second homes and occasional dwellings account for 42.1% of Menton's 29,757 dwellings (with 7.4% vacant and 56.5% of resident households owning their home) and 50.9% of Roquebrune-Cap-Martin's 14,042 dwellings (4.4% vacant, 56.0% owner-occupiers). Combined, roughly 19,700 of the 43,800 homes across the two towns—close to 45%—are second homes.

Three distinct buyer profiles share this stock:

• Monaco-employed households: Salaried professionals, hospitality staff and executives working in the Principality who buy primary residences—typically two- and three-room apartments with parking in Menton centre, Carnolès, Saint-Roman or Cabbé.
• French retirees and second-home buyers: Purchasers from Paris, Lyon and eastern France drawn by the sheltered micro-climate, Belle Époque architecture and flat seafront walks, concentrating on Garavan and the central seafront.
• International and cross-border buyers: Italian families from Liguria, Piedmont and Lombardy (Ventimiglia is ten minutes away by rail, and 21.4% of Monaco's hospitality workforce is Italian according to IMSEE in 2025), alongside British, Swiss, Scandinavian and Monaco-resident buyers targeting Cap Martin villas and top-floor terraces. Official statistics do not publish buyer nationality breakdowns at the commune level, so exact foreign-buyer shares cannot be quantified.

What does a foreign buyer pay in taxes and need to know about the rules?

France places no legal restriction on foreign nationals buying residential property, whether they reside in the European Union or outside it. However, owning a property in Menton or Roquebrune-Cap-Martin confers no automatic visa or residence right, and every purchase goes through the standard French notaire process.

Buyers should budget for three main fiscal and regulatory items in 2026:

• Transfer taxes (droits de mutation): Unlike most French departments that raised their rate in 2025–2026, the Alpes-Maritimes kept its departmental transfer tax rate at 4.50% according to the transfer-tax rates by department (DGFiP schedule as at 1 June 2026). Total registration duties on an existing home come to approximately 5.81% of the purchase price, before adding the notaire's regulated emoluments and disbursements.
• Real estate wealth tax (Impôt sur la Fortune Immobilière, IFI): Under French law (Service-public.fr, 2026), non-residents and residents alike are subject to IFI if the net value of their French real estate assets exceeds €1.3 million. Buyers resident in Monaco or Italy should take specialist cross-border tax advice before structuring a villa or penthouse acquisition.
• Furnished tourist lets (meublés de tourisme): Under the Le Meur law, the official guide to furnished tourist let rules (Ministère de la Transition écologique, in force 20 May 2026) makes registration compulsory nationwide via a single national teleservice, and allows communes to cap primary-residence short lets at 90 to 120 days a year. Buyers intending to let a second home short-term should check the exact municipal change-of-use and tax surcharge deliberations directly with the Menton or Roquebrune-Cap-Martin mairie before committing.

What are the risks of buying in Menton or Roquebrune-Cap-Martin?

A market that rises while the rest of the country pauses carries specific risks that buyers and their advisers should weigh carefully:

• Asking prices running ahead of sales: While CASAFARI apartment asking prices rose 4.8% year on year in Q3 2026, completed sales across the Alpes-Maritimes grew by a more modest 2.4% as departmental volumes dipped 4.3%. Over-ambitious sellers can sit on the market when buyers become selective.
• Thin liquidity in the villa segment: Because the house series rests on a small sample of high-value homes, price discovery on a Cap Martin or Garavan house cannot rely on commune averages; a single quarter swung -8.5% then +11.0% in 2026 purely on listing mix.
• Concentration on Monaco: Local purchasing power is heavily tied to Monaco's economy and to the stability of Franco-Monegasque cross-border employment and tax rules.
• Building age, energy ratings and coastal exposure: A large share of Menton's stock consists of older Belle Époque or post-war blocks where strict French energy-performance (DPE) rules can restrict rental use without renovation, while the coastline and hinterland valleys (as seen during Storm Alex in October 2020) require careful review of natural-risk diagnostics.
