Investing in France from Switzerland: Mortgage Guide 2026

Are you living in Switzerland and dreaming of owning a property in France? Good news: your situation offers you advantages that many investors envy. The historically strong Swiss franc, geographic proximity, and a more accessible French real estate market make this project a concrete opportunity.

But between choosing the currency for your mortgage, the nuances of the Franco-Swiss tax treaty, and the banks' requirements for non-residents, the process can seem complex. This guide accompanies you step by step to transform your project into reality—without unpleasant surprises.

Why invest in France from Switzerland?

The Swiss franc works in your favor. Historically, the CHF appreciates against the euro over the long term. This structural trend mechanically increases your purchasing power in the eurozone and makes French properties more accessible than they were a few years ago.

French real estate prices remain attractive compared to the Swiss market. In Geneva, expect over 13,000 CHF/m² on average. Across the border, in the Pays de Gex or Haute-Savoie, prices range between 4,000 and 6,000 €/m². The difference is significant, even for high-end properties.

Portfolio diversification is another compelling argument. By investing in France, you distribute your wealth between two stable economies, two currencies, and two real estate markets with different dynamics. This strategy protects your assets against the fluctuations of a single market.

💡 Remember: A rental investment in France can generate gross returns of 4 to 7% depending on the city, compared to 2 to 3% in Switzerland—while benefiting from leverage through the mortgage.

Financing: mortgage in CHF or euros?

The choice of currency is strategic. As a Swiss resident or cross-border commuter, you have access to an option few investors possess: the currency loan, repayable in Swiss francs.

The loan in CHF presents a major advantage: your income and your monthly payments are in the same currency. You eliminate the monthly exchange risk. Rates for this type of mortgage are generally lower than those offered in euros by French banks.

The loan in euros remains relevant if you are considering a rental investment. The rents received will be in euros, so it makes sense to repay in the same currency. In February 2026, average rates are around 3.13% over 15 years, 3.26% over 20 years, and 3.35% over 25 years. The best profiles can negotiate rates close to 3%. French banks also offer access to the Zero Interest Loan (PTZ) for first-time homebuyers in a primary residence.

The required personal contribution varies according to the circuit. Traditional banks generally require 20 to 30% from Swiss residents for a rental investment. However, Invexa works with specialized banking partners who accept contributions of 10 to 20%, conditions similar to those of French residents.

✅ Good to know: Thanks to Invexa's network of banking partners, you can access the best market conditions and finance up to 80-90% of your purchase, compared to 60-70% with traditional circuits.

⚠️ Attention: Your 2nd or 3rd pillar can be used as a contribution for the purchase of your primary residence. However, the withdrawn capital will be taxed in France—plan for this expense in your budget.

French regional banks (Crédit Agricole des Savoie, CIC, Crédit Mutuel, Caisse d'Épargne) offer specific deals for cross-border commuters. Some even allow mixing currencies: 50% in CHF, 50% in EUR.

Franco-Swiss tax treaty: avoiding double taxation

The good news: you will not be taxed twice. The Franco-Swiss tax treaty of September 9, 1966, amended several times, establishes clear rules to avoid this situation.

Fundamental principle: Real estate income is taxed in the country where the property is located. If you buy an apartment in Lyon, your rental income will be taxed in France, according to French tax law. Switzerland exempts these incomes from its tax—but may consider them to calculate the rate applicable to your other income (known as the "effective rate" method).

For real estate income in France, you will be subject to a minimum rate of 20% (or 30% beyond €27,478 of net income). Good news for Swiss residents: unlike expatriates outside Europe (USA, Singapore...), you are exempt from social levies (17.2%) on your French real estate income, thanks to Swiss-EU bilateral agreements. Only income tax applies—a significant tax advantage.

The LMNP scheme (Non-Professional Furnished Rental) can further reduce this taxation through property depreciation. Our article on taxation of real estate income for non-residents details these mechanisms.

Real Estate Wealth Tax (IFI) applies if the net value of your French real estate assets exceeds 1.3 million euros. Debts contracted for acquisition are deductible.

Real estate capital gains are also taxed in France upon resale. According to article 15 of the convention, a Swiss resident benefits from the same rate as a French resident—a benefit confirmed by the Council of State.

📋 Tax checklist:

• Declare your real estate income in France (form 2044 or 2042-C-PRO for LMNP)

• Inform the Swiss tax authorities of your French real estate income

• Keep proof of tax paid in France to avoid any disputes

Where to invest from Switzerland?

Cross-border areas offer an ideal compromise between proximity and profitability. Haute-Savoie (Annecy, Thonon-les-Bains), Ain (Pays de Gex), and Doubs (Besançon) attract strong rental demand driven by cross-border workers themselves.

The major French metropolises appeal for their potential for appreciation. Lyon, less than two hours from Geneva, combines economic dynamism with attractive rental yields. Paris remains a safe haven for wealth investors despite high prices.

University cities like Grenoble, Montpellier, or Toulouse offer interesting yields thanks to a constant student rental demand. The entry ticket is more accessible than in cross-border areas.

✅ Good to know: For a rental investment, prefer a mortgage in euros and rents in the same currency. This simplifies management and eliminates currency risk on your income.

Remote management can be delegated to a professional. Our guide on rental management for expatriates helps you choose the right formula.

Buying remotely: procedures and legal security

Good news: you do not need to be physically present in France to purchase a property. The French legal system allows the entire transaction to be completed remotely, provided you understand the steps and surround yourself with the right professionals.

Step 1: The offer to purchase. Once the property is found, you formalize your intention in writing. This document specifies the proposed price, conditions (subject to financing, for example), and a validity date. The offer can be sent by email—a verbal offer has no legal value in France.

Step 2: The sales agreement. It is the pre-contract that binds both parties. It includes the suspensive conditions (obtaining the mortgage, absence of easements, etc.) and sets the timeline of the transaction. Upon signing, you pay a deposit of 5 to 10% of the price, held in escrow by the notary.

💡 Remember: In France, you benefit from a 10-day withdrawal period after signing the sales agreement. This right does not exist in Switzerland—it is an additional protection for the buyer.

Step 3: The intermediate period (2-3 months). The notary performs mandatory checks: title of ownership, potential mortgages, easements, preemptive right waiver (the municipality or a tenant can substitute for you under certain conditions). Meanwhile, you finalize your financing.

Step 4: The authentic deed. The final signature formalizes the transfer of ownership. You can sign remotely via a notarial power of attorney: you appoint an agent (the notary himself, a relative, or a real estate hunter) who signs on your behalf. The notary can also propose secure electronic signing for certain acts.

Costs to anticipate:

• Notary fees: 7 to 8% of the price in the old, 2 to 3% in the new

• Registration fees included in notary fees (about 5.80%)

• Possible agency fees: 3 to 5% (often paid by the seller)

⚠️ Attention: All funds (contribution + fees) must be available in the notary's escrow account before the signature of the authentic deed. Anticipate international transfer delays (3 to 5 business days for a CHF → EUR transfer).

📋 Checklist before signing:

• Purchased offer accepted in writing

• Sales agreement signed + deposit paid

• Financing approved by the bank

• Notarial power of attorney drafted (if signing remotely)

• Funds transferred to the notary's account

• Home insurance certificate (required at key handover)
