French Guiana is part of France and the euro area, so a mortgage there follows French law, but the local market is small and unusual. Foreign buyers can purchase, yet lenders are cautious about the region's valuation and flood risks. Here is how financing works and where to be careful. Overview on our French Guiana page.
French law with a small local market
Because the territory is an overseas department, the Civil Code and the notary system apply exactly as in mainland France. Foreign nationals may buy property without special permission, and the rules for non-resident borrowers are those described in our countries directory as well.
The main lenders on the ground are Banque des Antilles Françaises and local branches of Crédit Agricole and BRED, with Société Générale present in some areas. Cayenne and Kourou account for most transactions.
In practice banks lend most readily to residents with local pay, civil servants and employees of the space centre.
Rates and borrowing limits
Mortgage rules follow the French 35% debt-service ceiling and 25-year standard term. Overseas banks apply local rates that can sit a little above those in mainland France. Non-residents commonly face 50% to 70% LTV.
Rates are generally fixed, and borrower insurance is compulsory. Premiums for people working in dangerous jobs or living in remote areas can be higher. Estimate your payments with the mortgage calculator.
Documents to prepare
French standards, French language: expect sworn translations.
| Document | Why it is asked for |
|---|---|
| Passport and visa status | Identity and legal presence |
| Tax returns | Income trend |
| Proof of funds for deposit | Source of equity |
| Compromis de vente | Contract terms |
| Diagnostic reports | Termites, flood, asbestos |
The buying sequence
Each stage matches mainland practice, with extra checks on land and risk.
- Check zoning and flood risk with the town hall.
- Sign a compromis de vente and pay the deposit.
- Obtain a loan offer and wait out the legal reflection period.
- Have the notary confirm title and boundaries.
- Sign the acte authentique.
- Register and pay taxes.
Alternatives
Many buyers fund through cash or by borrowing in mainland France or at home. Commercial lending for tourism ventures often needs a business plan. The consultation guide explains the legal side.
Costs
Costs mirror mainland France.
| Cost | Typical level (approx.) |
|---|---|
| Notary and taxes | Roughly 7% to 8% for older property |
| Agent | Often 5% to 8% |
| Bank fees | About 1% |
| Guarantee | Around 1% of loan |
Ground realities that affect lending
Distance, humidity and flooding all matter. A property in Cayenne's older districts needs a termite and damp survey. Insurers may refuse cover in flood-prone areas, and without insurance the bank will not release funds.
Because supply is thin, valuations can lag asking prices. Expect the bank's valuer to be conservative, and have extra cash ready in case the loan is capped below the contract price.
Land and informal occupation
Some plots have long-standing informal occupation or unclear boundaries. The notary should run searches, and you should refuse to complete if the cadastral plan and the physical site do not match.
Who realistically buys here
Most buyers are people relocating for work in Kourou, civil servants posted to the territory, or families with roots in the Caribbean and France. Pure investors face limited rental depth outside Cayenne, so a lender looking at a buy-to-let case will ask for evidence of tenant demand, such as existing lease contracts. A foreign buyer with no income in euros is the hardest case, and a personal guarantee from a French resident can sometimes make the difference.
Currency and cross-border funds
The euro removes exchange-rate risk if you earn in it. If you earn in another currency, transfer the deposit through a regulated provider and keep the proof of origin for the notary, who is bound by anti-money-laundering duties and will ask where the money came from. Transfers received without a clear paper trail can delay completion by weeks.
Buyers should also think about exit. The resale market is thin, homes can take many months to sell, and buyers often rely on the same few local banks, so a cash-heavy structure with a modest loan leaves you more room if you need to sell. Ask the agent for the number of comparable sales in the last two years, and treat a missing answer as information. Finally, check council and department charges, including the annual taxe foncière and water and waste fees, because rates can differ noticeably between communes and are not always visible in listings.
Tips
Compare costs on the cheap listings and the under 100k pages, but allow for the extra expense of surveys and insurance.
Insurance, not the interest rate, is often the real gatekeeper in French Guiana.
