Switzerland has the lowest home-ownership rate in Europe (~36%) and the most expensive residential market: a median Zurich apartment trades around CHF 1.4 million in 2026, with Geneva and Zug close behind. For a non-resident the picture is even harder, because the Lex Koller federal law (Bundesgesetz über den Erwerb von Grundstücken durch Personen im Ausland, BewG) imposes near-prohibitive restrictions on foreign acquisition of Swiss residential property. Add cantonal Handänderungssteuer of up to 3.3%, notary fees of 0.1–1%, the 80% LTV cap with mandatory amortization to 65% LTV in 15 years, and the perennial Eigenmietwert (imputed rent) income tax, and Switzerland is genuinely the most complex residential property market in Europe to navigate. This guide walks through the full process for both Swiss residents and non-residents.
Quick Answer (TL;DR): Lex Koller bars most non-residents from buying Swiss residential real estate without a permit; permits are issued under canton-by-canton quotas and almost exclusively for holiday homes in designated tourist zones (Verbier, Saas-Fee, Crans-Montana). EU/EFTA residents legally domiciled in Switzerland are exempt. Total transaction friction is 5–8% of purchase price: notary 0.1–1% by canton, land register 0.15–0.5%, Handänderungssteuer 0–3.3% (Zurich 0%, Vaud 3.3%), agent commission 2–5% (usually paid by seller). Mortgage maximum 80% LTV, with mandatory amortization to 65% LTV within 15 years. Eigenmietwert — an imputed rental value — is added to your taxable income each year (currently scheduled to be abolished from 2028, awaiting cantonal implementation). You can withdraw Säule 3a tax-advantaged savings to fund the down payment under WEF rules.

Methodology
We surveyed cantonal Grundbuch and tax administration tariffs for the most-traded residential markets in May 2026, along with the Federal Office of Justice's Lex Koller register and FINMA's mortgage-market guidance. Mortgage criteria reflect the FINMA self-regulation framework (SBVg / SwissBanking guidelines on residential lending) as practised by major Swiss mortgage lenders. All numerical references reflect public information as of 2026-05.
Lex Koller — the Decisive Filter for Non-Residents
The Federal Act on Acquisition of Real Estate by Persons Abroad (Bundesgesetz über den Erwerb von Grundstücken durch Personen im Ausland, BewG, commonly "Lex Koller") restricts the purchase of Swiss real estate by foreigners. The categories that matter:
Exempt — no Lex Koller authorisation needed:
- EU/EFTA citizens with legal domicile in Switzerland (B/C permit).
- Third-country nationals with C permit (settled residence) and effective Swiss residence.
- Purchase of property exclusively used as the buyer's primary residence at place of work.
- Purchase of commercial property (offices, retail, industrial, hotel) — Lex Koller does not apply to genuinely commercial assets.
Restricted — permit required, almost always denied unless tourist-zone holiday home:
- Non-resident foreigners (no Swiss domicile).
- Cross-border workers without C permit acquiring a second residence.
- Acquisition of residential investment property by a non-resident (buy-to-let).
For tourist-zone holiday homes (limited to designated communes in Valais, Graubünden, Bern Oberland, Ticino), each canton has an annual federal quota — typically 50–500 units per canton per year, allocated by the cantonal Lex Koller authority. Permitted properties have hard limits: max ~200m² living area, max ~1,000m² land, must be used as a holiday home (not rented out year-round).
For an ordinary German, French, or Italian buyer who does not live in Switzerland and is not buying in a designated tourist commune, the answer is essentially: no, you cannot buy a Zurich or Geneva apartment. The legal grey-zone workaround of buying through a Swiss corporate vehicle (AG) is also caught by Lex Koller's beneficial-ownership rules and is enforced.
The Mortgage Math: 80% LTV + Amortization to 65%
Swiss mortgage lending is governed by FINMA-supervised self-regulation administered by SwissBanking (the bankers' association) and embedded in cantonal-bank credit policy. The two ironclad rules:
1. Maximum LTV at origination = 80%. The buyer must provide at least 20% equity from own funds. Of those 20%, at least 10% must be "hard equity" — cash, brokerage assets, gifts, inheritances. The remaining 10% can come from Säule 2 (occupational pension) or Säule 3a withdrawal under the WEF (Wohneigentumsförderung, home-ownership promotion) regime.
2. Mandatory amortization to 65% LTV within 15 years (or by retirement, whichever is sooner). Above 65% LTV the bank requires monthly amortization payments. A CHF 1.0M property with an 80% mortgage of CHF 800k must amortize CHF 150k over 15 years — roughly CHF 10,000/year of principal repayment, on top of interest service.
3. Affordability rule (Tragbarkeit). Total housing cost (interest at a stress-test rate of typically 5%, plus 1% maintenance reserve, plus amortization) must not exceed 33% of gross household income. This is computed at the imputed 5% stress rate even if the actual rate is much lower — so a CHF 1.0M property with a CHF 800k mortgage requires roughly CHF 150k+ of gross income to qualify.
For a Zurich-resident couple earning CHF 220k combined, with CHF 200k saved cash + CHF 100k Säule 2/3a available for WEF withdrawal, the realistic affordable purchase is around CHF 1.2–1.4M — exactly the median Zurich apartment.
Säule 3a / Säule 2 Withdrawal for Property (WEF)
The WEF rules allow withdrawal of pension assets to finance owner-occupied primary residence:
- Säule 3a: Full balance available for first home, every 5 years thereafter.
- Säule 2 (occupational pension): Up to age 50, full vested termination benefit. After 50, half the vested benefit or the amount as of age 50, whichever is greater.
The withdrawn amount is taxed at the special "Vorsorgekapital" rate (often 4–7%) at the time of withdrawal. If you sell the property within the first three years, the Säule 2 withdrawal must be repaid into the pension fund.
This is genuinely powerful: a 35-year-old couple with combined CHF 80k in Säule 3a and CHF 150k in Säule 2 can mobilise CHF 230k for a property down payment, taxed at ~5% (~CHF 11.5k tax versus ~CHF 70k at full marginal income rate).
Transaction Cost Walkthrough
Notary (Notar / Notaire). In most cantons, the notary executes the public deed and handles land-register filing. Notary fees range 0.1% (Zurich) to 1% (Vaud, Geneva), often split between buyer and seller depending on cantonal practice.
Land register fee (Grundbuchgebühr). 0.15–0.5% of purchase price for the new title registration plus mortgage entry.
Handänderungssteuer (real-estate transfer tax). Levied by the canton or commune; rates vary dramatically:
- Zurich, Zug, Schwyz, Basel-Stadt: 0%.
- Bern: 1.8%.
- Ticino: 1.1%.
- Geneva: 3.0%.
- Vaud: 3.3% (highest in Switzerland).
Estate-agent commission. Typically 2–5%, usually paid by the seller in Switzerland (unlike Germany where it's split). Off-market transactions can avoid this.
Mortgage origination. Most Swiss banks do not charge a separate origination fee, but expect an indicative valuation fee of CHF 500–2,000 if a formal expert appraisal is required.
Total buy-side friction: Zurich/Zug ~0.5–1%; Bern/Ticino ~2–3%; Geneva/Vaud ~4–5%.
Annual Holding Costs
Eigenmietwert (imputed rent) — taxable as income. The Federal Court mandates that owner-occupiers add a notional rental value of their property to taxable income, valued at typically 60–70% of market rent (cantonal practice varies). For a Zurich apartment with a market rent of CHF 36,000/year, the Eigenmietwert is roughly CHF 22,000–25,000, added to taxable income each year and taxed at the marginal rate (~30% in Zurich → ~CHF 7,000/year extra tax).
Mortgage interest is deductible against Eigenmietwert and other income, as are maintenance costs (either lump-sum 10–20% or actual costs). The system is broadly neutral for high-mortgage owners but tax-positive for cash-rich owners with little mortgage debt.
Important 2026 update: Federal Parliament approved abolition of Eigenmietwert in 2024, with the change scheduled to take effect from 2028 once cantonal implementation is complete. Mortgage-interest deduction will also be abolished in parallel. Verify the latest status with ESTV before relying on long-term planning assumptions.
Property tax (Liegenschaftssteuer). Levied by some cantons and communes at 0.1–0.3% of taxable value annually. Zurich and several others do not levy this; Vaud, Valais, and Geneva do.
Wealth tax (Vermögenssteuer). The property's official taxable value (typically 60–80% of market value) counts toward your kantonal wealth-tax base. Mortgage debt is deductible. Net effect on a high-LTV property in early years is usually mildly negative wealth-tax impact.
Step-by-Step Purchase Process
- Lex Koller pre-check. If non-resident, confirm permit availability in the cantonal Lex Koller authority before any offer.
- Mortgage pre-approval. Obtain a Finanzierungsbestätigung from a major bank (UBS, ZKB, Raiffeisen, Migros Bank). Valid usually 3 months.
- Property search. Major portals: homegate.ch, immoscout24.ch, comparis.ch. Off-market via local Treuhand or estate agent.
- Reservation / Reservationsvereinbarung. Non-binding deposit of CHF 5,000–20,000, refundable except for misconduct.
- Notary draft (Kaufvertrag-Entwurf). Notary prepares the public deed. Both parties review — get an independent legal opinion if non-native German/French speaker.
- Bank final approval & mortgage contract. Sign the Hypothekarvertrag.
- Public notarisation. Both parties (or their proxies) sign before the notary. Funds wired to notary escrow.
- Grundbuch registration. Notary files the deed; takes 1–4 weeks for new title to issue.
- Possession / Übergabe. Keys handed over on agreed date, usually 30–90 days after signing.
FAQ — Switzerland-Specific
Can a German resident buy a Zurich apartment? Generally no, unless they obtain Swiss residency (B/C permit) first. EU/EFTA citizens who become resident in Switzerland can buy without a Lex Koller permit. Non-resident Germans can only buy in designated tourist communes via a Lex Koller permit, with the strict size and use limits that apply.
What is Lex Koller exactly? The Federal Act on Acquisition of Real Estate by Persons Abroad (BewG, 1983, amended). It restricts non-resident foreigners from acquiring residential real estate in Switzerland. Commercial real estate is exempt. The act is enforced via cantonal authorities and beneficial-ownership rules.
Can I use my Säule 3a to buy property? Yes, under the WEF (Wohneigentumsförderung) rules. Full balance available for first owner-occupied home; can be used again every 5 years. Withdrawal is taxed at the special low Vorsorgekapital rate (~4–7%). Säule 2 (occupational pension) is also withdrawable under WEF, with restrictions after age 50.
Will Eigenmietwert really be abolished in 2028? Federal Parliament adopted the legislation in 2024. Implementation is scheduled for 2028, contingent on cantonal coordination. Mortgage-interest deduction will also be eliminated in parallel — net effect is positive for cash-rich owners and negative for high-LTV recent buyers. Track ESTV publications before making any 5-year-plus assumption.
How much down payment do I need for a CHF 1.0M apartment? Minimum CHF 200,000 (20% LTV cap), of which at least CHF 100,000 must be "hard equity" (cash, brokerage, gifts) and not from Säule 2/3a. The remaining CHF 100,000 can come from Säule 2/3a withdrawal under WEF. Plus transaction costs of CHF 5,000–50,000 depending on canton.
