Can expats buy an apartment in Switzerland?
Yes — but the rules depend on your residence permit. Buying an apartment in Switzerland as an expat is fully unrestricted if you hold a C settlement permit. With a B residence permit, you can generally purchase a primary residence, though the Lex Koller law may require cantonal authorisation. Without a Swiss residence permit, purchasing residential property is severely restricted and in most cases not possible outside designated tourist zones.
Understanding which rules apply to your situation is the essential first step when buying an apartment in Switzerland as an expat.
Residence permits and purchasing rights
C permit (settlement permit)
If you hold a C permit, you are treated the same as a Swiss citizen for property purchasing purposes. You can buy any type of residential property — apartments, houses, investment properties — anywhere in the country, with no authorisation required. This is the simplest scenario for buying an apartment in Switzerland as an expat.
B permit (residence permit)
B permit holders who are nationals of an EU or EFTA country can purchase a primary residence without Lex Koller authorisation in most cantons. The property must serve as your main home — buying a second home or an investment property with a B permit is generally restricted. Some cantons require notification or a formal declaration of primary residence intent.
Non-EU/EFTA nationals with a B permit face stricter scrutiny. Purchasing a primary residence is usually possible, but cantonal authorisation is required, and the property must genuinely be your main residence.
No Swiss residence permit
Non-residents can only buy property in designated holiday zones (primarily in Alpine resort cantons such as Valais, Graubünden, Bern Oberland, and Vaud). These purchases require cantonal authorisation and are subject to restrictions on property size, usage, and resale. Buying a standard apartment in a city is not possible without a residence permit.
The Lex Koller law explained
The Lex Koller law (formally the Federal Act on the Acquisition of Real Estate by Persons Abroad) regulates property purchases by individuals who do not hold Swiss citizenship or a C permit. Its purpose is to prevent excessive foreign ownership of Swiss real estate. In practice, it primarily affects B permit holders buying anything other than a primary residence and non-residents buying holiday property. C permit holders and Swiss citizens are exempt.
When authorisation is required, the cantonal authority reviews the application and typically grants it for genuine primary residences. The process adds a few weeks to the timeline but is rarely a barrier for straightforward purchases.
Financing: what expats need to know
Financing is often the most demanding aspect of buying an apartment in Switzerland as an expat. Swiss banks require a minimum of 20% equity, of which at least 10% must come from savings, investments, or other non-pension sources. Up to 10% can come from your Swiss pension fund (second pillar), and third-pillar retirement savings can also be used.
The bank will test affordability at an imputed interest rate of around 5%, not the actual mortgage rate you will pay. Total imputed housing costs — mortgage interest, amortisation, and maintenance — must not exceed roughly one-third of your gross household income. For expats who are new to Switzerland, banks may apply additional caution: shorter employment history, unfamiliar income structures, or assets held abroad can complicate the process.
Starting the financing conversation early — ideally before you begin searching — is strongly advisable. A mortgage pre-approval gives you clarity on your budget and strengthens your position when making an offer.
The buying process step by step
Once you have confirmed your purchasing rights and secured financing in principle, the process of buying an apartment in Switzerland as an expat follows these steps:
- Search for properties on portals (Homegate, ImmoScout24, Comparis) or through agents
- Visit the property and review the documentation: land register extract, floor plans, condominium regulations, renewal fund balance, energy certificate
- Make an offer, typically through the seller's agent
- If the offer is accepted, the notary prepares the purchase agreement
- Both parties review the draft, and a signing date is set — typically four to eight weeks after agreement
- At the signing, the notary authenticates the agreement and submits it for land register entry
- The transfer is completed once registered — usually two to six weeks after signing
What to watch out for as an expat buyer
When buying an apartment in Switzerland as an expat, pay particular attention to the following:
- Condominium ownership (Stockwerkeigentum/PPE) regulations: these govern shared costs, renovations, and restrictions on use — read them carefully before committing
- The renewal fund (Erneuerungsfonds/fonds de rénovation): a healthy fund means lower risk of unexpected special assessments; a depleted fund is a warning sign
- The imputed rental value: as an owner-occupier, you will be taxed on a notional rental income, which may come as a surprise if you are unfamiliar with the Swiss tax system
- Cantonal variation: notary fees, transfer taxes, and property tax rules differ by canton — factor these into your budget
Key takeaways on buying an apartment in Switzerland as an expat
Buying an apartment in Switzerland as an expat is entirely achievable — millions of foreign nationals own property here. The process is well-structured, the legal framework is clear, and the main barriers are regulatory (Lex Koller for B permit holders) and financial (the 20% equity and affordability requirements). Start by understanding your permit-based rights, get financing pre-approved, and take the time to learn the local market. With preparation, the process is straightforward — and the result is ownership in one of the world's most stable and desirable property markets.
