Mortgage Options for Foreign Buyers

Who qualifies as a foreign buyer

For mortgage purposes, Swiss banks distinguish between several categories of foreign buyers. EU/EFTA nationals with a B permit who are purchasing a primary residence in Switzerland are treated similarly to Swiss residents and can access standard mortgage products. Non-EU/EFTA nationals with a B permit may face more restrictive conditions. Non-resident foreign buyers — those purchasing a holiday home under a Lex Koller authorisation — face the most restrictive mortgage conditions.

The category that applies to you depends on your nationality, your Swiss residence status and the intended use of the property. Clarifying your category before approaching banks is important — it determines which mortgage products are available and what conditions apply.

Mortgage options for non-resident foreign buyers

Non-resident foreign buyers purchasing a holiday home in Montreux can access mortgage financing from Swiss banks, but typically face stricter conditions: a maximum LTV of 60 to 70 percent (compared to 80 percent for Swiss residents); higher equity requirements (30 to 40 percent of the purchase price); and more stringent income documentation requirements.

Swiss private banks — particularly those with international client bases — are often the most accommodating for non-resident foreign buyers. They are experienced in assessing international income sources, foreign assets and complex financial structures. International banks with Swiss operations (UBS, Credit Suisse, Julius Baer, Pictet) are also options.

Income and asset documentation

Swiss banks require comprehensive documentation of income and assets from all mortgage applicants. For non-resident foreign buyers, this typically includes: the last 2–3 years of tax returns; the last 2–3 years of payslips or business accounts (for self-employed buyers); bank statements for the last 6–12 months; evidence of the source of the equity contribution; and a statement of assets and liabilities.

For buyers with complex income structures — business owners, investors, executives with variable compensation — the documentation requirements can be extensive. Working with a mortgage broker who specialises in international clients can help navigate the process.

Currency considerations

Non-resident foreign buyers whose income is in a currency other than Swiss francs face an additional consideration: currency risk. If the mortgage is in Swiss francs and the buyer's income is in euros, dollars or another currency, fluctuations in the exchange rate affect the effective cost of the mortgage.

Some Swiss banks offer mortgages in foreign currencies (euros, dollars) for non-resident buyers, which eliminates the currency risk on the mortgage itself. However, the property's value is in Swiss francs, so there remains a currency risk on the equity portion of the investment.
