Buying Property in St Martin / Sint Maarten Island

1. Introduction — One Island, Two Nations

St Martin and Sint Maarten share a single island of 87 square kilometres — making it the smallest landmass in the world to be divided between two sovereign nations. The northern 53 square kilometres constitute Saint-Martin, a French Collectivite d'Outre-Mer (COM) — the same constitutional status as St Barts, with which it shares both proximity and the French legal framework. The southern 34 square kilometres form Sint Maarten, a constituent country of the Kingdom of the Netherlands — autonomous in domestic affairs but part of the Dutch constitutional framework, with the Euro and the US Dollar both widely used and with no income tax or capital gains tax under the Dutch Caribbean fiscal framework applicable to Sint Maarten. Between these two jurisdictions runs what is routinely described as one of the world's most benign borders: an open crossing with no immigration control, no customs formality, and no barrier of any kind — a legacy of the 1648 Treaty of Concordia that has governed the island's division for over 375 years.

This constitutional duality is the defining structural feature of the St Martin/Sint Maarten property market — and it is the first thing any prospective buyer must understand. The two sides of the island are not merely culturally and administratively different; they operate under entirely different legal systems, property ownership frameworks, purchase processes, currencies for legal transactions, residency and immigration rules, and fiscal regimes. A buyer who purchases on the French side (Saint-Martin) is subject to French property law, the French notarial system, and — crucially — the French fiscal framework modified by Saint-Martin's COM status. A buyer who purchases on the Dutch side (Sint Maarten) is purchasing within the Kingdom of the Netherlands' constitutional framework, with Dutch civil law principles, a distinct property registration system, and the Sint Maarten fiscal regime. These are not variations on a theme — they are fundamentally different legal and fiscal environments sharing a geography.

The island is also the gateway to St Barts. Princess Juliana International Airport on the Dutch side — one of the most recognisable airports in the world for its spectacular aircraft approaches over Maho Beach — is the primary international hub for this part of the northern Caribbean, with direct services from Amsterdam, New York, Miami, Boston, and other major cities. The 10-minute island-hop from SXM to St Barts, operated by Winair, makes Sint Maarten the essential connection point for every St Barts-bound traveller. This gateway function gives Sint Maarten and, by extension, the French side, a tourism and connectivity infrastructure that is disproportionate to the island's size and that supports a vibrant and internationally diverse property market.

For property buyers, the combined island offers a genuinely diverse market: from the ultra-luxury villa estates of Terres Basses (on the French side's south-west peninsula) through the cosmopolitan lifestyle of Orient Bay (the French side's most famous beach resort) to the Dutch side's Philipsburg waterfront, its Simpson Bay resort corridor, and the Dawn Beach and Oyster Pond luxury developments on the Atlantic coast. Both sides have no income tax and no capital gains tax — the fiscal frameworks differ in their legal basis but converge on this critically important shared characteristic.

This guide covers both sides of the island comprehensively — the constitutional and legal framework of each, the property purchase process specific to each side, the taxes and costs applicable on each side, the property market across the whole island, and the residency and lifestyle implications for buyers choosing between the French and Dutch jurisdictions.

2. Geography, Character & Lifestyle

The Island's Landscape

St Martin/Sint Maarten is a hilly volcanic island of 87 square kilometres, with a coastline of remarkable variety: sheltered Caribbean bays on the western coast, exposed Atlantic beaches on the eastern coast, the complex network of lagoons (Simpson Bay Lagoon on the Dutch side is one of the largest lagoons in the Lesser Antilles — a major factor in the island's yachting infrastructure), and the beaches that have made the island internationally famous. The central spine of hills — reaching Pic du Paradis at 424 metres on the French side, the island's highest point — creates dramatic viewpoints, varied microclimates, and the hillside villa settings that characterise the premium residential addresses on both sides.

The French Side — Saint-Martin

Orient Bay (Orient Beach)

Orient Bay — Baie Orientale — is the most internationally recognised address on the French side and one of the most celebrated beaches in the Caribbean. A long arc of white sand on the Atlantic-facing east coast, lined with beach restaurants, watersports operations, beach clubs, and villa rentals, Orient Bay has an energy and cosmopolitan character that is entirely distinct from the quieter residential areas of the French interior. The beach's reputation as the French Caribbean's most social and most hedonistic beach environment — including a designated naturist section — has made it a magnet for the European beach lifestyle market. Properties around Orient Bay — from beach-adjacent apartments to hillside villas overlooking the bay — represent the French side's most active and most internationally traded property market.

Grand Case — The Gourmet Capital

Grand Case, on the north-west coast of the French side, is widely described as the culinary capital of the Caribbean — a single road (Le Boulevard de Grand Case) lined with a concentration of restaurants of extraordinary quality and diversity, from sophisticated French Creole dining to fresh seafood and roti lolos (casual outdoor barbecue stands). For buyers who want the French side's most refined lifestyle address — fine dining on the doorstep, a small bay beach, a quiet residential character — Grand Case is the island's most distinctly French and most gastronomically serious neighbourhood. The Grand Case Airport (L'Esperance) is a small airstrip serving island-hop services, including connections to St Barts and other nearby islands.

Terres Basses — The French Side's Ultra-Premium Peninsula

Terres Basses — the low-lying western peninsula of the French side, connected to the main island by a narrow causeway — is Saint-Martin's most prestigious and most private residential address. The peninsula encompasses Plum Bay, Long Bay, Baie Rouge (one of the island's most beautiful beaches, known for its red-tinged sand and clear water), and a collection of private villa estates that represent some of the finest and most valuable residential properties in the northern Caribbean. Terres Basses is a quiet, low-density, authentically residential community — there are no resort hotels, no commercial strips, and no tourist infrastructure on the peninsula itself. The lifestyle is private, beach-oriented, and defined by the quality of the properties and the character of the owner community, which includes prominent international buyers drawn by the setting and the privacy. Property values in Terres Basses are the highest on the French side — prime beachfront villas have transacted at prices that approach St Barts levels for the finest positions.

Marigot — The French Capital

Marigot, on the west coast of the French side, is the capital of the Collectivite de Saint-Martin — a charming French-Caribbean town with a covered market, a waterfront with cruise ship facilities and yacht anchorage, French-owned boutiques and restaurants, and the ferry terminal for high-speed services to Anguilla and St Barts. The Fort Louis above the town provides panoramic views of the bay and across to Anguilla. Marigot is primarily a commercial and administrative hub rather than a residential destination for international buyers, but the surrounding hillsides and the bay-adjacent residential areas have a modest residential property market.

The Dutch Side — Sint Maarten

Philipsburg — The Capital and Cruise Hub

Philipsburg, the capital of Sint Maarten, is one of the Caribbean's busiest cruise ship ports — its Front Street waterfront strip is one of the most intensely touristed commercial environments in the Lesser Antilles when the major cruise ships are in port, with duty-free shops, jewellers, and casinos catering to the day visitor market. For property buyers, Philipsburg itself is primarily relevant as a commercial hub rather than a residential destination, though the Great Bay beachfront and the surrounding hills above the city have residential appeal for buyers who want proximity to the capital's services and its Great Bay beach.

Simpson Bay and the Lagoon

The Simpson Bay area — centred on the vast Simpson Bay Lagoon, one of the largest lagoons in the Lesser Antilles — is the Dutch side's most important yachting and marina centre. The lagoon's sheltered waters accommodate hundreds of yachts, several major marina facilities (including Port de Plaisance, Isle de Sol Yacht Club, and the Simpson Bay Marina), and a boatyard and marine services infrastructure that makes Sint Maarten one of the premier yacht repair and refit destinations in the Caribbean. The Simpson Bay resort corridor — with casinos, restaurants, beach bars, and a concentration of tourist-facing commercial activity around the lagoon and the airport approach — is the Dutch side's most active tourism hub. Properties in and around Simpson Bay range from marina-front apartments and townhouses to larger villas overlooking the lagoon and the airport.

Dawn Beach and Oyster Pond — The Atlantic Coast

The Atlantic-facing eastern coast of Sint Maarten — centred on Dawn Beach and extending to the Oyster Pond bay that straddles the French-Dutch border — has developed into the Dutch side's most prestigious residential address. Dawn Beach is one of the Dutch side's finest beaches — a long, exposed Atlantic arc with consistently good surf and a quality of natural setting that is among the best on the island. The Le Galion Beach hotel and residences at Oyster Pond, straddling the international border, exemplify the island's dual-jurisdiction character. Properties in the Dawn Beach and Oyster Pond area range from mid-market condominiums to larger villa estates on the surrounding hills with Atlantic and Caribbean views.

Climate and Hurricane Irma — The Essential Context

St Martin/Sint Maarten has a tropical climate with a dry season (December–May) and a wet season (June–November). The island is directly in the path of Atlantic hurricanes tracking into the Caribbean. On 6 September 2017, Hurricane Irma — a Category 5 storm with winds of 295 km/h — made direct landfall on St Martin/Sint Maarten, causing catastrophic damage across both sides of the island. The storm destroyed or severely damaged an estimated 90% of structures on the island, killed dozens of people, and triggered a humanitarian crisis of extraordinary scale. The subsequent reconstruction has been ongoing for years — the French side's reconstruction was coordinated through French government emergency funds and EU assistance; the Dutch side's reconstruction drew on Dutch Kingdom support and international aid. By 2026, substantial reconstruction has occurred and the island has recovered significantly, but the rebuild has been uneven — some areas and some properties have been fully restored to post-Irma modern standards, while others remain in varying states of repair or partial reconstruction.

Hurricane Irma is not historical context — it is active due diligence. Any buyer of any property on St Martin/Sint Maarten must treat the post-Irma construction status of that specific property as the most important single due diligence item. The questions are: Was this property damaged in Irma? If so, what was the extent of the damage? Was it fully rebuilt, or partially repaired? To what construction standard was the rebuild executed — hurricane-resistant modern codes, or to the previous pre-Irma standard? Is the insurance history of the property clear — were Irma-related claims made and settled? Were any structural issues revealed or exacerbated by the storm? These questions must be answered with documentary evidence, not assurances, before any purchase commitment is made on either side of the island.

3. Is St Martin / Sint Maarten Right for You?

St Martin/Sint Maarten occupies a genuinely unique position in the Caribbean property market — and the buyers for whom it is most compelling are those who value the specific combination of factors that no other Caribbean island provides: two legal systems and two fiscal frameworks on a single open-border island, both with no income tax and no CGT; exceptional international air connectivity through one of the Lesser Antilles' most important airports; the St Barts gateway premium; and a lifestyle that combines the best of the French and Dutch Caribbean traditions in a setting of genuine beauty and extraordinary cosmopolitan energy.

St Martin / Sint Maarten is particularly well suited to:

• ⦁ European buyers — particularly French, Belgian, Dutch, and other EU nationals — for whom the French COM framework (French side) or the Kingdom of the Netherlands framework (Dutch side) provides a familiar legal and constitutional environment within a Caribbean lifestyle setting
• ⦁ Sailing and yachting enthusiasts for whom the Simpson Bay Lagoon, the island's multiple marina facilities, and the central position in the Lesser Antilles sailing circuit make St Martin/Sint Maarten one of the Caribbean's premier yacht bases
• ⦁ Buyers who want the flexibility of dual-jurisdiction choice — who value the option of choosing between French and Dutch legal frameworks based on their specific nationality, residency plans, and lifestyle preferences
• ⦁ Investors focused on the rental market who want the most cosmopolitan and most internationally diverse rental demand base in the Lesser Antilles, sustained by the exceptional SXM air connectivity and the St Barts gateway premium
• ⦁ Long-term residents who want a pathway to EU citizenship (French side) through genuine residency — the five-year naturalisation pathway is one of the most valuable long-term outcomes available through Caribbean property ownership

St Martin / Sint Maarten may be less well suited to:

• ⦁ Buyers for whom the post-Irma construction quality risk is unacceptable — for buyers who cannot thoroughly verify the rebuild status and construction quality of a specific property, the island's hurricane history and the potential for undisclosed post-storm issues represent a level of risk that some will not wish to accept
• ⦁ Buyers seeking a citizenship by investment programme — neither side offers CBI, and for buyers whose primary objective is second citizenship, the Eastern Caribbean CBI islands (St Kitts, Grenada, Saint Lucia, Antigua, Dominica) are the appropriate destinations
• ⦁ Buyers who want an ultra-exclusive, low-density, quiet Caribbean environment — the island's cosmopolitan, active character and the presence of Philipsburg's cruise ship traffic and Sint Maarten's casino and nightlife infrastructure make it a vibrant destination rather than a secluded one
• ⦁ British buyers who want extended stays on the French side without engaging the French immigration system — the 90/180-day Schengen limit is a real constraint that requires active planning

For buyers who connect with its proposition — two nations, two legal systems, two culinary traditions, one open border, no income tax on either side, the Caribbean's most famous airport approach, St Barts ten minutes away, and Grand Case's extraordinary restaurants as the backdrop for evenings — St Martin/Sint Maarten delivers a Caribbean property experience of unique character and unusual depth. There is nowhere else in the world quite like it.

4. Infrastructure & Practical Living

Princess Juliana International Airport

Princess Juliana Airport (SXM) on the Dutch side is the island's primary international gateway and one of the most recognisable airports in the world — the spectacular, low-level aircraft approach over Maho Beach, where planes pass at extremely low altitude over sunbathing spectators, has made the airport a social media phenomenon and a tourist attraction in its own right. The airport was severely damaged by Irma and underwent extensive reconstruction — confirm the current terminal facilities and operational status before publication. Services include:

Getting There: Air Access

V.C. Bird International Airport sits in the north-east of the island and is one of the better-connected airports in the Eastern Caribbean. Direct services include:

• ⦁ KLM: Direct services from Amsterdam Schiphol — the primary European gateway, connecting St Martin/Sint Maarten to KLM's extensive European and global network
• ⦁ American Airlines: Direct services from Miami — the primary US gateway for the island
• ⦁ United Airlines: Services from Newark/New York
• ⦁ Delta Air Lines: Seasonal direct services from Atlanta and other US cities
• ⦁ Air France: Services via Guadeloupe and Martinique for French-market connections
• ⦁ Winair, Air Antilles, and regional operators: Island-hop services throughout the Lesser Antilles — including the essential 10-minute service to St Barts (Gustaf III Airport)
• ⦁ Fast ferry services to St Barts: High-speed ferries from both the French side (Marigot) and the Dutch side (Bobby's Marina, Philipsburg) to Gustavia — a scenic 45–60 minute crossing

Getting Around

The island is small enough to navigate in under an hour from north to south — the open border means that getting around is purely a matter of driving (or taking taxis), not of crossing any formality. Roads are generally adequate in the main resort corridors but can be narrow and congested in the Philipsburg and Simpson Bay areas during peak cruise ship days. The main road between Marigot (French side) and Philipsburg (Dutch side) is the primary cross-border route and can be heavily congested. A vehicle — or reliable access to taxis or rental vehicles — is essential for comfortable living on either side of the island.

Everyday Living

• ⦁ Languages: French (French side official), Dutch (Dutch side official), English (universally spoken across both sides), and a distinctive local Creole (English-based) widely spoken in Sint Maarten. The island's cosmopolitan character means that Spanish, Haitian Creole, and many other languages are heard in daily life. English is the practical lingua franca of commerce and tourism on both sides
• ⦁ Currency: Euro on the French side (legal tender); Netherlands Antillean guilder (ANG) on the Dutch side, pegged at ANG 1.79 = USD 1.00. US dollars are universally accepted across both sides for commercial transactions — the island functions as a de facto dual-currency economy in everyday life. Property transactions for international buyers on the Dutch side are typically priced and settled in USD
• ⦁ Shopping and dining: Some of the best duty-free shopping in the Caribbean (Philipsburg), one of the Caribbean's finest restaurant concentrations (Grand Case), and everything in between across the two sides. The island's cosmopolitan population supports an extraordinary diversity of cuisines and shopping options for its size
• ⦁ Cost of living: Moderate by Caribbean resort standards, though imported goods carry a premium. Significantly more affordable than St Barts for everyday living, and broadly comparable to other Eastern Caribbean destinations for basics. The Dutch side has more accessible supermarkets and commercial infrastructure than the French side for everyday shopping
• ⦁ Internet and connectivity: Good quality broadband and mobile data coverage across most of the island. The resort areas have reliable high-speed connectivity; more remote hillside areas can have variable service. Confirm connectivity specifically for any rural or hillside property

5. Key Contacts & Professional Advice

• ⦁ French side notaire: Essential for all French-side property transactions. One of the small number of locally based notarial offices, or a notaire from Guadeloupe or Martinique familiar with Saint-Martin COM property. For complex transactions or high values, also engage a French avocat specialising in property and international transactions.
• ⦁ French side avocat: For buyer-side independent representation beyond the neutral notaire — particularly for transactions above EUR 1 million, corporate structures, trust holdings, or complex cross-border legal and tax planning. Must have specific expertise in French overseas collectivity property law and the Saint-Martin fiscal framework.
• ⦁ Dutch side Sint Maarten attorney: Independent buyer-side representation for all Dutch-side transactions. The Sint Maarten attorney conducts due diligence, advises on the purchase agreement, and represents the buyer's interests alongside the notary.
• ⦁ Dutch side Sint Maarten notary: State-appointed civil law notary who manages the notarial deed and registration for Dutch-side transactions — neutral, not a buyer advocate.
• ⦁ Sint Maarten tax adviser: For Dutch-side buyers needing advice on Turnover Tax implications for rental operations, annual land tax obligations, and the Dutch Caribbean fiscal framework.
• ⦁ Home-country tax adviser: For all non-resident buyers from jurisdictions with worldwide taxation or significant home-country tax obligations — particularly urgent for US citizens and US persons. Saint Martin/Sint Maarten's no-tax environment does not override home-country obligations.
• ⦁ Independent structural surveyor — post-Irma: For any property on either side of the island, an independent structural survey by a qualified engineer with post-Irma assessment experience is non-negotiable. Do not rely on seller assurances or agent representations about post-storm condition — obtain independent documentary evidence.
• ⦁ International health insurance and evacuation cover: Comprehensive private health insurance with medical evacuation from St Martin/Sint Maarten to a specialist facility (CHU de Martinique for French-side evacuations, or Puerto Rico/Miami for Dutch-side) should be in place before taking occupancy.

7. Constitutional Framework — Two Jurisdictions Explained

Saint-Martin — French Collectivite d'Outre-Mer

Saint-Martin, the French northern side, has been a Collectivite d'Outre-Mer (COM) since 15 July 2007 — the same constitutional change that simultaneously created the St Barts COM. Before 2007, Saint-Martin was an administrative commune of Guadeloupe, subject to all French national legislation including the full French tax code. Since 2007, the Collectivite de Saint-Martin has its own elected Territorial Council, its own executive, and its own legislative competences across defined policy areas — most significantly, taxation.

For property buyers on the French side, the key consequences of COM status are:

• ⦁ French property law applies in full: The notarial system, the acte authentique, the compromis de vente, the ten-day cooling-off period, the conditions suspensives, the diagnostics obligatoires, and the droits de mutation framework all apply on the French side of Saint-Martin exactly as they apply in St Barts, Guadeloupe, and metropolitan France
• ⦁ Local fiscal autonomy: The Collectivite de Saint-Martin exercises fiscal autonomy similar to St Barts — specifically, no local income tax, no local capital gains tax on real estate, and no local IFI (French wealth tax). These are the same core fiscal advantages as St Barts, arising from the same COM fiscal autonomy framework
• ⦁ No Loi Pinel: The French Pinel Outre-Mer scheme does not apply in Saint-Martin — as in St Barts, the COM's fiscal autonomy places it outside the metropolitan French tax incentive framework for property investment
• ⦁ EU territory: Saint-Martin is a French overseas collectivity; EU citizens have freedom of movement. The Euro is the legal tender for property transactions and official financial activity
• ⦁ Open border: The Treaty of Concordia border with Sint Maarten is open — no passport required, no customs formality. This open border is a constitutional and treaty commitment of extraordinary longevity (since 1648) and creates a daily reality in which residents of both sides move freely across the island for work, shopping, leisure, and social life

Sint Maarten — Dutch Constituent Country

Sint Maarten, the Dutch southern side, became a constituent country of the Kingdom of the Netherlands on 10 October 2010 — known locally as '10-10-10' — when the Netherlands Antilles was dissolved. Sint Maarten is now an autonomous country within the Kingdom, like Aruba and Curacao, with its own constitution, its own parliament (the Staten), its own government, and its own legal system. The Netherlands retains responsibility for Sint Maarten's defence and foreign affairs, and the Dutch Supreme Court serves as the final court of appeal.

For property buyers on the Dutch side:

• ⦁ Dutch civil law framework: Sint Maarten's property law derives from the Dutch civil law tradition — the civil code applicable in Sint Maarten has its roots in the Dutch Burgerlijk Wetboek (Civil Code), though localised for the Caribbean context. Property transfers require a notarial deed (notariele akte) before a locally licensed civil law notary — the process has similarities with the French notarial system but operates under a different legal framework
• ⦁ No income tax on individuals: Sint Maarten levies no personal income tax on individuals. This is the fundamental fiscal characteristic of Sint Maarten for property owners — rental income, employment income, and other personal income are not subject to Sint Maarten personal income tax
• ⦁ No capital gains tax: There is no capital gains tax in Sint Maarten on the disposal of real property. All appreciation accrues to the owner free of Sint Maarten CGT
• ⦁ EU territory: Saint-Martin is a French overseas collectivity; EU citizens have freedom of movement. The Euro is the legal tender for property transactions and official financial activity
• ⦁ Turnover tax (not VAT): Sint Maarten levies a Turnover Tax (TOT) on business revenue including commercial real estate rental activity — this is not the same as an income tax or a VAT, but is levied on gross rental turnover from commercial operations. The applicable rate and threshold for short-term rental property operations should be confirmed with a Sint Maarten tax adviser
• ⦁ Transfer tax: Sint Maarten levies a transfer tax on property transactions — the primary acquisition cost tax, paid at closing. The applicable rate should be confirmed with a local notary or attorney
• ⦁ Currency: The Netherlands Antillean guilder (ANG, symbol Naf) is the official currency, pegged to the USD at ANG 1.79 = USD 1.00 — a peg maintained since 1971. In practice, US dollars are universally accepted and widely used in commercial transactions across Sint Maarten. Property transactions for international buyers are typically priced and settled in USD

The Open Border — A Practical Reality

The open border between Saint-Martin and Sint Maarten is not merely a legal technicality — it is a lived daily reality that shapes the island's property market in distinctive ways. Residents of the French side routinely cross to the Dutch side for Princess Juliana Airport access, for the larger commercial and retail infrastructure of Philipsburg and Simpson Bay, and for entertainment. Residents of the Dutch side cross to the French side for Orient Bay's beaches and restaurants, for Grand Case's celebrated restaurant strip, and for the more tranquil residential character of the French interior. Buyers on either side are effectively buying access to the whole island's lifestyle, not just to their own jurisdiction's facilities.

For property buyers, the open border means:

• ⦁ Airport access: Princess Juliana Airport (on the Dutch side) is the primary international gateway for the entire island — French side property owners use it as freely as Dutch side residents, with no border formality
• ⦁ Dual lifestyle access: The French side's restaurants and beaches (Grand Case, Orient Bay) and the Dutch side's casinos, shopping, and nightlife (Philipsburg, Simpson Bay) are equally accessible to residents of both sides
• ⦁ Emergency services and healthcare: Both sides have their own healthcare and emergency infrastructure, but residents of both sides can access facilities on the other side without restriction
• ⦁ The border is marked but not enforced: Crossing points are identified (typically by a small monument at the main road crossings) but there is no checkpoint, no immigration officer, and no formality of any kind
