What Buying and Living in Martinique Costs:
Notary Fees and the 'Vie Chère' Gap

Martinique's costs have a particular feature: an official, published measure of how much more it costs to live there than on the French mainland. It anchors the cost side of a move, and the buying costs follow the same French rules as Guadeloupe.

What you pay to buy

A notary is mandatory, and the "notary fees" include the taxes. The total is about 7% to 8% for existing property and 2% to 3% for new builds. One notary-fee calculator gives total fees of about 7.1% for an average Martinique purchase, with €16,550 on a 60-square-metre property at the island average of €3,912 per square metre. Another puts an existing purchase in Fort-de-France at about 7.42%, or €14,852 on €200,000, and a new build at about 2.33%, or €4,662.

The transfer-duty rate is disputed. One calculator says Martinique did not apply the 2025 increase and charges 5.81%. Another site says Martinique, Guyane and Réunion applied it and charge 5.00%, with Guadeloupe left at 4.50%. Those are opposite accounts of which departments raised the rate, and the Guadeloupe cost article in this series records the mirror-image conflict. A notary can confirm the rate for a specific sale, and the total should land near 7% either way.

VAT in the overseas departments is 8.5% on agency fees, and a developer-type source says it also applies to new-build sales against 20% on the mainland. French tax schemes for overseas investment require French tax residence, so non-residents should not assume access to them.

What property costs

Averages differ by source: about €3,235 per square metre on one portal in September 2026, €3,240 for existing and €4,050 for new property on a finance firm's page. The south, with Les Trois-Îlets and Sainte-Anne, costs more than Fort-de-France or the Atlantic coast, covered in the areas article in this series. The finance firm also puts long-term rents in central Fort-de-France at about €13 to €14 per square metre a month, which is a claim from a firm with a commercial interest.

What things cost: the official gap

INSEE, France's statistics office, ran a price comparison survey in 2022. It found that consumer prices in Martinique were 14% above mainland France. Food was about 40% higher, and health about 13% higher. Seen from the mainland basket, food prices were 50% higher. Guadeloupe's gap was 16%, French Guiana's 14% and Réunion's 9%, so Martinique's is higher than Réunion's and lower than Guadeloupe's.

The 2024 "vie chère" protests, over the cost of living, put this on the national agenda. The French competition authority published an opinion at the government's request, summarised by an island news site, that put the gap at 13.8% overall and 40.2% for food in 2022. An economic news site explains the causes as distance, a small market and local taxation, and the authority's work covers structural factors in more detail. These are 2022 figures, so current prices may differ.

No reliable monthly budget estimates specific to Martinique turned up beyond these official gaps, so none are given.

What this means for a buyer

Budget about 7% to 8% for notary fees on an older property, and ask a notary for the exact transfer-duty rate. For living costs, expect the gap to be widest for food, and remember that euro prices are set within French rules, not the dollar or Eastern Caribbean markets of the English-speaking islands. The relocation guide in this series covers entry and long-stay visas, and the areas article covers where prices sit.
