Many international entrepreneurs and senior professionals reach a point where they want to live in Switzerland and own their home here. The good news: it is largely possible. The important condition: residence status, not nationality, decides what you can buy — and Swiss banks remain among the most disciplined mortgage lenders in Europe.
Who is allowed to buy?
The Lex Koller draws a sharp distinction by residence status. Three groups, three different positions:
EU/EFTA citizens with a B permit
Can acquire a principal residence (house or condominium) without authorisation. Second homes and pure investment properties are not permitted.
Non-EU residents with a B permit (e.g. UAE, US, UK, China)
Can acquire an owner-occupied principal residence only. Vacation properties and any kind of yield-driven acquisition are off the table.
C permit holders (all nationalities)
Treated equivalently to Swiss citizens. Full access to the residential market.
Living abroad, no Swiss residence
Acquisition of residential property is not possible. Exceptions exist only for inherited property and specific second-home quotas in tourist zones.
Affordability — the harder hurdle
Even when the right to buy is established, the financing test is where most international buyers underestimate the requirements. Swiss mortgage standards are conservative by design:
Equity: A minimum of 25% of the purchase price must come from your own funds. Of that, at least 10% must be "hard" equity — not drawn from your Swiss pension.
Affordability: Monthly housing costs (calculated at a notional 5% interest rate, plus amortisation, plus maintenance) cannot exceed 33% of gross household income.
Income evidence: Swiss banks lean heavily on Swiss-domiciled income. Foreign earnings are accepted, but typically discounted — bonuses, dividends and certain self-employment income face haircuts in the underwriting model.
A realistic example
"Swiss banks are conservative — that's what protects the market. It also makes the entry point demanding. International buyers who arrive well-prepared, with the right bank and the right structure, do well."
— UniExe – SuisseThe route, step by step
- Confirm residence statusWithout a valid B or C permit, residential acquisition is not on the table. This is the question to answer before all others.
- Stress-test your equity position25% is the floor. 35% gives you access to better terms and avoids the second mortgage tranche entirely.
- Run a real affordability calculationUse the bank's standard 5% notional rate, not today's actual rate. If the file doesn't work at 5%, it won't pass underwriting.
- Choose the right bank for your profileCantonal banks are typically more receptive to EU residents. Private banks have more flexibility for higher-net-worth non-EU buyers. Retail banks rarely lend on complex international profiles.
- Bring in local advice before signingThe mistakes that cost real money are usually structural — wrong bank, wrong canton, wrong evidence of income — not the headline price.
Where international buyers go wrong
- Misreading the Lex Koller. Buying without the right to do so is a voidable transaction. The deposit and the property can both be lost.
- Presenting foreign income poorly. Income statements that work in London or Dubai may not translate cleanly to Swiss underwriting. Repackaging matters.
- Underestimating transaction costs. Transfer tax, notary fees and broker commissions add roughly 2–5% on top of the purchase price, depending on canton.
- Picking the wrong bank. Some lenders simply do not write mortgages for non-EU residents. Others specialise in exactly that profile. The wrong choice burns weeks.
- Ignoring cantonal differences. Zurich's room for manoeuvre is narrow. Other cantons take a more pragmatic view. The deal has to fit the place.
