Investing in France from Switzerland: Mortgage Guide 2026

Do you live in Switzerland and dream of becoming a homeowner in France? Good news: your situation gives you advantages many investors envy. The historically strong Swiss franc, geographic proximity, and a more accessible French real estate market make this project a concrete opportunity.

However, between choosing the currency for your mortgage, the subtleties of the France–Switzerland tax treaty, and bank requirements for non-residents, the process can seem complex. This guide supports you step by step to turn your project into reality — without unpleasant surprises.

Why invest in France from Switzerland?

The Swiss franc works in your favor. Historically, the CHF has appreciated 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 with the Swiss market. In Geneva, expect more than CHF 13,000/m² on average. On the other side of 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 premium properties.

Wealth diversification is another strong argument. By investing in France, you spread your assets across two stable economies, two currencies, and two real estate markets with different dynamics. This strategy protects your assets against the volatility of a single market.

💡 Key takeaway: A rental investment in France can generate gross yields of 4% to 7% depending on the city, versus 2% to 3% in Switzerland — while benefiting from leverage through a mortgage.

Financing: mortgage in CHF or euros?

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

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

A euro mortgage remains relevant if you are planning a rental investment. The rents you receive will be in euros, so it is logical to repay in the same currency. In February 2026, average rates stand at around 3.13% over 15 years, 3.26% over 20 years, and 3.35% over 25 years. The strongest profiles can negotiate rates close to 3%. French banks also provide access to the interest-free Mortgage (PTZ) for first-time buyers of a primary residence.

The required down payment varies by channel. Traditional banks generally require 20% to 30% from Swiss residents for a rental investment. However, Invexa works with specialized banking partners that accept down payments of 10% to 20%, conditions similar to those for 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, versus 60–70% through traditional channels.

⚠️ Important: Your 2nd or 3rd pillar can be used as a down payment for purchasing your primary residence. However, the withdrawn capital will be taxed in France — plan for this cost in your budget.

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

France–Switzerland tax treaty: avoiding double taxation

The good news: you will not be taxed twice. The France–Switzerland tax treaty of September 9, 1966, amended several times, sets 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, under French tax law. Switzerland exempts this income from its own tax — but may take it into account to calculate the rate applicable to your other income (the so-called “effective rate” method).

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

The LMNP regime (Non-Professional Furnished Rental) can reduce this taxation further thanks to property depreciation. Our article on rental income taxation for non-residents details these mechanisms.

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

Capital gains on real estate are also taxed in France upon resale. Under Article 15 of the treaty, a Swiss resident benefits from the same rate as a French resident — an advantage confirmed by the Conseil d'État.

📋 Tax checklist:

• Declare your rental 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 dispute

Where to invest from Switzerland?

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.

Major French metropolitan areas are attractive for their appreciation potential. Lyon, less than two hours from Geneva, combines economic momentum with attractive rental yields. Paris remains a safe haven for wealth-focused investors, despite high prices.

University cities such as Grenoble, Montpellier, or Toulouse offer attractive returns thanks to consistent student rental demand. The entry ticket is more accessible there than in border areas.

✅ Good to know: For a rental investment, prioritize a euro mortgage and rents in the same currency. This simplifies management and eliminates exchange-rate risk on your income.

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

Buying remotely: process and legal security

Good news: you do not need to be physically present in France to buy real estate. The French legal system allows the entire transaction to be completed remotely, provided you understand the steps and are supported by the right professionals.

Step 1: The purchase offer. Once the property is found, you formalize your intention in writing. This document specifies the offered 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 preliminary sale agreement. This pre-contract binds both parties. It includes conditions precedent (mortgage approval, absence of easements, etc.) and sets the transaction timeline. Upon signing, you pay a 5% to 10% security deposit of the price, held in escrow by the notary.

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

Step 3: The interim period (2–3 months). The notary carries out mandatory checks: title deed, potential mortgages/liens, easements, and waiver of pre-emption rights (the municipality or a tenant may replace you under certain conditions). In parallel, you finalize your financing.

Step 4: The notarized deed. The final signature formalizes the transfer of ownership. You can sign remotely via a notarial power of attorney: you appoint an authorized representative (the notary, a relative, or a property finder) who signs on your behalf. The notary may also offer secure electronic signature for certain deeds.

Costs to plan for:

• Notary fees: 7% to 8% of the price for existing properties, 2% to 3% for new-build properties

• Registration duties included in notary fees (around 5.80%)

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

⚠️ Important: All funds (down payment + fees) must be available in the notary’s escrow account before signing the notarized deed. Anticipate international transfer times (3 to 5 business days for a CHF → EUR transfer).

📋 Checklist before signing:

• Purchase offer accepted in writing

• Preliminary agreement signed + security 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)
