The 20% Down-Payment Rule in Switzerland: What Equity You Actually Need to Buy Property

Why Switzerland sets a high equity bar

Unlike some countries where buyers can enter the market with 5-10% down, Swiss mortgage lending is built around a much more conservative principle: borrowers should have a substantial financial buffer before they take on a mortgage. The long-standing benchmark is that you need at least 20% of the purchase price in equity, with the bank financing the remaining 80% through a mortgage.

This isn't a legal requirement in the sense of a law passed by parliament — it's a self-regulatory standard that Swiss banks have adopted, largely to keep household debt and the property market stable. But because virtually every mortgage lender in Switzerland applies it, it functions as the de facto rule for anyone planning to buy.

Not all equity is equal: the "hard equity" distinction

The 20% figure is only part of the story. Swiss banks typically split required equity into two categories:

• At least 10% must be "hard equity" (sometimes called harte Eigenmittel in German). This generally means savings, investments, gifts, inheritances, or proceeds from selling other assets — money that isn't tied up in your retirement savings.
• The remaining 10% (up to the 20% total) may come from your occupational pension fund, known as Pillar 2 (BVG/LPP). Many employed residents in Switzerland accumulate meaningful balances here, and it's common to use part of this money toward a home purchase.

In practice, this means if you're buying a property for CHF 1,000,000, you'd typically need at least CHF 100,000 in genuine savings, plus another CHF 100,000 that could come from your pension fund — assuming your bank applies the standard split. Some banks are more conservative and may ask for a higher proportion of hard equity, especially for foreign buyers or non-residents, so always confirm the specific policy with your lender.

Using your pension fund: what to know

Withdrawing or pledging Pillar 2 assets for a home purchase is common practice, but it comes with trade-offs:

• Withdrawing funds early reduces your future retirement benefits and may affect disability or survivor's insurance coverage.
• Pension withdrawals used for property are usually only permitted for your primary residence — vacation homes or investment properties typically don't qualify.
• There can be tax implications on withdrawal, which vary by canton.
• Instead of withdrawing, some buyers choose to pledge their pension assets as collateral rather than cashing them out, which preserves the retirement capital but may affect how the bank calculates affordability.

The right choice depends heavily on your age, career stage, and overall retirement planning — this is an area where speaking to a mortgage adviser and your pension fund directly is essential.

It's not just about equity — affordability matters too

Even with 20% in hand, Swiss banks won't lend based on equity alone. They also assess affordability, generally requiring that your ongoing housing costs — mortgage interest, amortization, and maintenance — not exceed roughly a third of your gross household income. Crucially, banks calculate this using a theoretical, higher interest rate (not today's actual rate), to ensure you could still afford the property if interest rates rise significantly. This stress-testing approach is standard across Swiss lenders, though exact assumptions can differ slightly from bank to bank.

Amortization: paying down the loan over time

Swiss mortgages are structured differently from those in many other countries. Lenders typically require you to pay down ("amortize") the mortgage to around two-thirds of the property's value within a set period, commonly 15 years or by retirement age, whichever comes first. This amortization can be direct (reducing the loan balance) or indirect (paying into a Pillar 3a account that's later used to pay down the loan). The specifics depend on the bank and the mortgage product chosen.

Extra considerations for expats

If you're not a Swiss or EU/EFTA national, or don't hold a C permit, your ability to buy property at all may be restricted under the Lex Koller rules, which limit foreign ownership of Swiss real estate, particularly for non-primary residences. Even where you're eligible to buy, some banks apply stricter equity or income requirements to foreign nationals or non-residents, since risk assessment can differ. Policies vary significantly by institution, so it pays to shop around and clarify your situation early.

Key takeaway

Budgeting for a Swiss property purchase means planning for considerably more than a 20% down payment in the abstract — you need to know how much must be genuine savings, how your pension fund can (or can't) be used, and whether your income comfortably covers the bank's affordability test under stress-tested interest rates.
