“I’ve had a one-bedroom flat let unfurnished in Le Lamentin for eight years, my tenant has just given notice: what if I turned it into an Airbnb?” I hear this question almost every month from Martinican owners weary of an unfurnished yield that’s stalling. As an island resident and furnished-rental manager, I guide them through this decision. Switching an unfurnished rental to furnished in Martinique means changing legal status, taxation, clientele and logistics — a move that often pays off here in the Caribbean, provided you crunch the numbers coldly before moving the first sofa.
This guide is educational and up to date for 2026; it does not replace the advice of a chartered accountant.
Why consider switching to furnished letting in Martinique
Unfurnished letting (empty), under a three-year lease, secures a modest but steady rent. Furnished tourist lets ride the island’s demand — a French overseas department of some 360,000 inhabitants. In coastal towns, the income gap is considerable. Take a realistic 45 m² one-bedroom flat in Les Trois-Îlets:
- let unfurnished, it rents for around €750/month, i.e. €9,000/year in gross rent;
- as a furnished tourist let, at €110/night with a cautious 60% occupancy rate (the dry season, December to April, runs nearly full, the wet season far less), it generates around €24,000/year.
On paper, furnished letting doubles or even triples turnover. But this gross figure is deceptive: the switch to LMNP in Martinique comes with costs and uncertainties, and seasonality is pronounced — Carnival in February-March boosts Fort-de-France, while the low cyclone season (June to November) thins the calendar.
The real costs to subtract from the dream
Net income is eaten away by items that are absent or lighter in unfurnished letting:
- complete furnishing made costlier by the octroi de mer (sea customs duty): €8,000 to €15,000 to seriously equip a one-bedroom flat;
- cleaning and laundry between each stay, €40 to €70 per turnover in a tropical climate;
- platform commission (15% and up) or concierge fees;
- seasonal vacancy and replacement of furniture attacked by salt and sun;
- tourist tax to collect and remit to the town.
Once these items are deducted, furnished letting generally stays ahead, but the gap narrows.
Calculating your opportunity: unfurnished versus furnished, numbers in hand
To decide whether to convert an unfurnished rental into a furnished one in an overseas department, compare not the gross figures but the net amounts after costs and tax. Let’s return to our Les Trois-Îlets one-bedroom flat.
- Unfurnished letting (micro-foncier regime): €9,000 in rent, 30% allowance, €6,300 base, tax of about €2,970 (30% bracket + 17.2% social levies). Estimated net: around €5,000/year.
- Furnished tourist let (LMNP under the actual-cost regime): €24,000 in income, €9,000 to €11,000 in real costs (cleaning, concierge, octroi de mer on the furniture, energy, accountant), plus the depreciation of the property and furniture, which often wipes out tax in the early years. Estimated net: €11,000 to €14,000/year.
The €6,000 to €9,000 annual gap justifies the furnishing, paid off in one to two years. But in a low-tourism town, or far from the southern beaches (Les Salines in Sainte-Anne, Le Diamant), a poorly booked furnished let won’t always beat a secure unfurnished one. It all depends on your micro-market.
When furnished letting clearly wins
The switch almost always pays off when your property meets these criteria:
- a seaside or tourist location: Sainte-Anne, Les Trois-Îlets, Le Diamant, Le François, La Trinité/Tartane, Saint-Pierre;
- character or an outdoor feature (terrace, bay view, pool);
- proximity to Aimé Césaire airport (in Le Lamentin) or to a flagship site (the Rum Route, Mount Pelée, the Caravelle Peninsula);
- the ability to delegate remote management.
Conversely, a purely residential property with no tourist appeal is often better valued unfurnished.
The change in tax status: from property income to LMNP
In unfurnished letting, your rent counts as property income (revenus fonciers). As soon as you furnish, it becomes industrial and commercial profits (BIC): you fall under the non-professional furnished landlord (LMNP) status as long as your income stays below €23,000/year or below the household’s other earned income.
This change unlocks depreciation, a mechanism absent from property income, which each year deducts a fraction of the property’s and furniture’s value with no actual cash outlay; in Martinique, the octroi de mer inflates this depreciable value and amplifies the benefit. To fully understand the micro-BIC and actual-cost regimes, browse our Martinique guide.
The concrete steps of the transition
Achievable remotely from mainland France, in this order:
- wait for the tenant to leave (an unfurnished lease can’t be terminated overnight);
- furnish according to the statutory list, tropical version: bedding and mosquito nets, blackout blinds, fitted kitchen, air conditioning or ceiling fans, salt-resistant outdoor furniture;
- declare the start of activity on the single business-formalities portal to obtain a SIRET number;
- opt for the actual-cost regime, often the winner in the overseas departments, rather than micro-BIC;
- declare the furnished tourist let at the town hall, with a registration number to display depending on the town;
- check the change-of-use rules, regulated in Fort-de-France and certain towns.
Allow two to four months between the decision and the first night.
The Martinican pitfalls of the switch
A few traps that can sabotage an otherwise promising transition:
- underestimating the octroi de mer, which inflates the furniture bill by 20 to 40% compared with mainland France;
- neglecting remote management: with a 5- to 6-hour time difference (dialling code +596; -5h in winter, -6h in summer), handling check-ins and the unexpected from mainland France is unsustainable without a local contact;
- forgetting the car: on an island where it’s strongly recommended, a poorly served property rents less well;
- misjudging your insurance and ignoring the sargassum on the Atlantic side, which weighs on the seasonal appeal of certain towns.

FAQ
Do I have to wait for the tenant to leave before switching to furnished in Martinique?
Yes. An unfurnished lease runs for three years (six if the landlord is a company) and can only be terminated by the owner at expiry, with notice, for reoccupation, sale or a legitimate reason. You can’t furnish while the unfurnished lease is running: the simplest path is to wait for notice given by the tenant, as in most cases we handle.
Is switching to furnished really more profitable in the Caribbean?
In the majority of cases in tourist towns (Sainte-Anne, Les Trois-Îlets, Le Diamant), yes: furnished letting doubles or triples gross turnover and remains more profitable even after cleaning, concierge and octroi de mer. But in a low-tourism town or for a property far from the beaches, a secure unfurnished let can hold its own. It all comes down to a net calculation, property by property.
Which tax regime should I choose after switching to LMNP?
In Martinique, the actual-cost regime is often the winner: it deducts real costs and allows depreciation of the property and furniture, whose value is inflated by the octroi de mer. The result: a taxable base that is often nil for several years. The micro-BIC, simpler, may suffice for a classified furnished let with low costs. A chartered accountant will decide based on your situation.
How long does converting an unfurnished rental to furnished take?
Allow two to four months between the decision and the first night. This timeframe covers furnishing (lengthened by importing and the octroi de mer), the start-of-activity declaration for the SIRET number, the town-hall declaration and any change-of-use authorisation. Planning ahead avoids missing the start of the dry season, the high season.
