From renting to owning: buying your first home in Switzerland
To buy in Switzerland you need at least 20% equity (10% in 'hard' equity from savings or pillar 3a, and up to 10% from pillar 2) and to pass the affordability test - total housing cost (notional 5% mortgage rate + 1% maintenance + amortisation) must stay below one third of gross income. Start lender conversations 3-6 months before bidding.
Overview
Buying property is the moment Swiss financial planning becomes serious: pension capital, tax, mortgage structure and insurance all interact. The right sequence saves both time and tens of thousands of francs over the life of the loan.
Steps from rent to ownership
- 1
Calculate your maximum purchase price
Take 20% of (price) as required equity and apply the 1/3 rule on the imputed cost. A household with CHF 200,000 gross income and CHF 250,000 equity can usually afford a property around CHF 1.0-1.2m as of 2025.
- 2
Assemble your equity stack
Savings, securities, pillar 3a, vested-benefits accounts, gifts and inheritance count as hard equity. Pillar 2 (Vorbezug or pledge) can fund up to 10% but cannot be the full 20% - and a withdrawal triggers a one-off tax.
- 3
Pre-qualify with 2-3 lenders
Cantonal banks, big banks, insurance companies (Swiss Life, Allianz, Helvetia) and online platforms (Hypoplus, Moneypark, Resolve) compete. Pre-qualification letters strengthen your offer.
- 4
Choose your mortgage mix
SARON (variable, ties to the SARON rate plus margin) vs fixed (1-15 years). A common split: 60-70% fixed for stability, 30-40% SARON for flexibility, ladder maturities across years to avoid renewal cliffs.
- 5
Plan amortisation: direct vs indirect
Indirect amortisation via pillar 3a keeps mortgage interest higher (more tax deduction) and builds tax-deductible 3a capital - usually better for higher earners. Direct amortisation reduces debt faster - simpler and often better for retirees.

Budget for notary, transfer and ongoing costs
Notary and Grundbuch fees: 1-5% of purchase price depending on canton. Annual costs: mortgage interest, 1% maintenance reserve, imputed rental-value tax (Eigenmietwert), building and household insurance.
Frequently asked questions
Can B-permit holders buy property in Switzerland?+
Yes, for primary residence used by themselves. Restrictions apply to investment property and holiday homes under Lex Koller - C-permit holders, EU/EFTA residents with B and Swiss citizens are not affected for primary homes.
Is SARON or fixed-rate mortgage better?+
Neither is always better - SARON historically averages lower over long periods but exposes you to rate volatility; fixed buys certainty at a premium. Most Swiss borrowers split the loan into tranches with different rates and maturities.
How long does a Swiss mortgage approval take?+
From submitting a full file to a written offer: typically 2-4 weeks. Add another 4-8 weeks for property valuation, notarisation and Grundbuch entry. Plan 8-12 weeks from offer-accepted to keys-in-hand.
What is Eigenmietwert?+
Imputed rental value - the notional rent you 'pay yourself' as owner, added to your taxable income. It is offset by mortgage interest and maintenance deductions. Federal reform is in progress as of 2025; rules may change.
