Swiss Mortgage Rules for Foreign Buyers

How Swiss mortgages work for non-resident buyers: LTV limits, bank requirements, currency risk, which banks lend, and what to prepare before you apply.

Swiss banks will lend to non-resident foreign buyers. But the terms are stricter, the equity requirements are higher, and the documentation demands are more extensive than for Swiss residents. Understanding these rules before you start looking saves time and prevents the unpleasant surprise of discovering your budget is smaller than you assumed.

For the full financing picture (including Swiss residents and cash buyers), see the comprehensive financing guide.

The Key Numbers

Loan-to-Value (LTV)

Buyer Type Maximum LTV Minimum Equity
Swiss resident, primary residence 80% 20%
Swiss resident, second home 60-70% 30-40%
Non-resident foreign buyer 50-65% 35-50%

The LTV for non-residents is typically 50-65% of the bank's valuation (not the purchase price). This distinction matters enormously.

The Valuation Gap

Swiss banks value alpine property conservatively. They use hedonic models and comparable sales data, and they apply an "alpine discount" that reflects:

The practical impact: A property you are buying for CHF 12 million may be valued by the bank at CHF 9-10 million. If the bank offers 60% LTV on their valuation:

Item Amount
Purchase price CHF 12,000,000
Bank valuation CHF 9,500,000
Maximum mortgage (60% of valuation) CHF 5,700,000
Equity required CHF 6,300,000
Effective LTV on purchase price 47.5%

You expected to need 40% equity (CHF 4.8M). You actually need 52.5% (CHF 6.3M). This gap catches many foreign buyers.

What to do: Ask the bank for their indicative valuation of your target property before committing. Better yet, get pre-approved before you start viewing seriously.

What Banks Require

Documentation

Swiss banks require extensive documentation from non-resident borrowers. Expect to provide:

The Affordability Test

Swiss banks apply a stress test to ensure you can service the mortgage even if rates rise:

For non-residents, the bank may discount your foreign-currency income by 10-20% to account for exchange-rate risk.

Example:

Item Amount
Mortgage amount CHF 5,000,000
Stress-rate interest (5%) CHF 250,000/year
Amortisation (to 65% over 15 years) ~CHF 70,000/year
Maintenance (1% of CHF 10M property) CHF 100,000/year
Total calculated housing costs CHF 420,000/year
Required gross income (x3) CHF 1,260,000/year

If your income is in GBP at £800,000, the bank may discount it to an equivalent of ~CHF 900,000, which would fall short. You would need to demonstrate additional assets or income.

Currency Risk

The mortgage is denominated in CHF. If your income is in another currency, you carry exchange-rate risk:

Mortgage Types for Foreign Buyers

The same products are available as for Swiss residents, but rates may carry a premium:

Type Indicative Rate (Mid-2026, Non-Resident) Notes
SARON (variable) ~0.9-1.3% Resets periodically. Lower cost, but exposed to rate changes.
Fixed 5 years ~0.8-1.2% Moderate lock. Popular for predictability.
Fixed 10 years ~1.8-2.1% Longer lock. Higher rate, but certainty.

Non-resident premium: Expect rates 0.1-0.3% above published Swiss resident rates. The exact premium depends on your profile, the property, and your relationship with the bank.

For most non-resident buyers, we recommend either a 5-year or 10-year fixed rate. The certainty is worth the modest premium over SARON, especially when you are managing the property from abroad and want no surprises.

Which Banks Lend to Non-Residents

Swiss Universal Banks

UBS is the dominant lender in the Swiss luxury segment. After absorbing Credit Suisse in 2023, they have the largest dedicated team for resort property and non-resident lending.

Raiffeisen and the Cantonal banks (including BEKB, the Cantonal Bank of Bern) also lend to non-residents, though their appetite and experience with luxury alpine property varies.

Private Banks

For UHNW clients, Julius Baer, Lombard Odier, Pictet, and Vontobel may offer mortgage financing as part of a wealth management relationship. Terms are typically more flexible:

The trade-off: you typically need to hold a substantial investment portfolio with the bank (often CHF 5-10M+).

International Banks

HSBC, Barclays, JP Morgan, and other international banks with Swiss private banking operations lend on Swiss property for their existing clients. Terms are relationship-dependent and vary widely.

The Application Process

Timeline

Step Duration
Initial enquiry and documentation submission 1-2 weeks
Bank review and valuation 2-4 weeks
Indicative offer 1 week after review
Formal approval 1-2 weeks after offer acceptance
Total 4-8 weeks

Start the mortgage process in parallel with your property search, not after you have found a property. Pre-approval gives you certainty and strengthens your negotiating position.

Tips for a Smooth Application

  1. Prepare documents early. Gather 24 months of bank statements, 3 years of tax returns, and a full statement of assets before you approach the bank.
  2. Be transparent about income sources. Swiss banks are thorough. Undisclosed income or assets discovered later will cause delays.
  3. Use a mortgage broker if unfamiliar with Swiss banking. An independent broker can approach multiple banks and negotiate on your behalf.
  4. Factor in the valuation gap. Do not assume the bank will value the property at the purchase price. Budget for a 10-20% shortfall.
  5. Consider the whole relationship. If you are moving investment assets to Switzerland, discuss this with the bank alongside the mortgage. A broader relationship may improve your terms.

Amortisation Requirements

Swiss banks require you to reduce (amortise) the mortgage to 65% of the property value within 15 years. After that, the remaining debt can stay in place indefinitely (you pay interest only).

For non-residents starting at 50-65% LTV, the amortisation requirement may be minimal or zero (you are already at or near 65%).

Two methods:

For non-residents, direct amortisation is the standard approach.

Frequently Asked Questions

Can a non-resident get a mortgage in Switzerland? Yes. Expect 50-65% LTV on the bank's valuation, extensive documentation, and rates slightly above Swiss resident rates.

How much deposit do I need? 35-50% of the purchase price, possibly more if the bank values the property below the purchase price (common in alpine property).

Do I need a Swiss bank account? Yes. Mortgage payments and property costs are processed through a Swiss bank account. Open one early in the process.

Can I get a mortgage in my home currency? No. Swiss property mortgages are denominated in CHF. Your repayments are in CHF regardless of your income currency.

What if I already bank with UBS or another Swiss bank? Existing clients typically receive better terms: faster processing, potentially higher LTV, and competitive rates. Discuss the mortgage as part of your overall banking relationship.

Is it better to buy cash or finance? For Swiss tax residents, maintaining a mortgage can be tax-efficient (mortgage interest deduction). For non-residents, the tax benefit is limited, but financing preserves liquidity for other investments. See the full analysis.
