Investing in Swiss Real Estate: The Complete Guide

Every year, Swiss real estate attracts both Swiss and international buyers in search of stability, quality of life and a market recognised for its solidity. Switzerland, however, applies a precise framework covering financing, taxation and, for foreign buyers, specific rules such as the Lex Koller. This guide looks at why to invest, what to invest in, and how to structure your project, with a particular focus on Verbier and the Val de Bagnes.

Why invest in Swiss real estate?

The Swiss property market stands out for its political and economic stability, a currency widely regarded as a safe haven, and a supply of properties structurally limited by the scarcity of buildable land, particularly in mountain areas. These characteristics make it a sought-after asset class, whether for a primary or secondary residence or for a rental investment.

In resorts such as Verbier, demand is further supported by an international clientele drawn to the ski area, the quality of local infrastructure and a year-round alpine lifestyle. This combination of a stable national market and a high-end local positioning explains the sustained interest in property in the region.

It should be noted that investing in property guarantees neither capital appreciation nor rental yield: each project should be assessed on its own merits, holding horizon and location.

What type of property should you invest in?

Several options are available to investors, Swiss and foreign alike, depending on their objectives:

• A secondary residence, purchased for personal use and, potentially, occasional seasonal letting.
• A rental property, primarily intended for letting, either year-round or seasonally.
• Ownership through a Swiss property company, a structure better suited to larger projects or institutional investors, subject to its own tax rules and, where controlled by persons abroad, to the Lex Koller.

The choice between a chalet, an apartment or an income property depends on your objectives (personal use, rental income, long-term value creation) and is best discussed in advance with a local professional familiar with the specifics of each area.

How to invest in Swiss real estate: the key steps

Acquiring a property in Switzerland follows a structured path:

• Define your project and budget, taking into account available equity and financing capacity.
• Identify the property, ideally with the support of a local agency that knows the market and can shortlist properties matching your criteria.
• Check your eligibility, particularly as a foreign buyer (see the Lex Koller section below).
• If necessary, secure financing by approaching one or more banks.
• Sign the deed of sale before a notary, a mandatory step in Switzerland for any transfer of property ownership.
• Pay the transfer duties and related costs, then register the property with the land registry.

Local support, particularly for valuing the property and negotiating, helps secure each of these steps.

Equity and financing: what changes depending on the type of property

Financing a property purchase in Switzerland relies on well-established banking practices. These are indicative commercial norms, not uniform legal thresholds across institutions, and they vary considerably depending on how the property will be used:

• Main residence (occupied by the buyer): banks generally require at least 20 % equity, of which a minimum of 10 % must be “hard” equity (savings, securities, gifts). Occupational pension fund assets (2nd pillar) and tied pension assets (pillar 3a) can cover the remaining portion, through an early withdrawal or a pledge.
• Secondary residence (a holiday home not used as the main residence): requirements are considerably higher, with equity generally above 40 % of the purchase price. Occupational and tied pension fund assets cannot generally be used for this type of acquisition.
• Investment property (a building or property intended for letting): banks generally require a minimum of 25 % equity, with the balance financed through borrowing. Pension fund assets generally remain excluded, unless the buyer also occupies part of the property. A minimum amortisation schedule applies, typically stricter than for a main residence.

In all cases, banks assess the borrower’s financial capacity using a theoretical “stress” interest rate (generally around 5 %), deliberately higher than the rate actually paid, to check that the borrower could absorb a rise in interest rates. These calculated costs (theoretical interest, amortisation, maintenance), rather than the instalments actually paid, should generally not exceed one third of income. For an investment property, part of the expected rental income may be factored into this calculation, depending on each bank’s practice.

These rules can vary between institutions: a discussion with your bank or a mortgage broker remains essential to accurately assess your borrowing capacity for the type of property in question.

The legal framework for foreign buyers: the Lex Koller

The acquisition of real estate in Switzerland by a person domiciled abroad is governed by the federal act on the acquisition of real estate by persons abroad, commonly known as the Lex Koller. The decisive criterion is not the type of residence permit itself, but whether the person has a domicile that is legally established and effective in Switzerland within the meaning of the Civil Code, that is, the centre of their vital interests, together with the intention to settle there on a lasting basis.

The essentials:

• • Swiss nationals, as well as EU/EFTA nationals who have a domicile legally established and effective in Switzerland, are not considered persons abroad under the Lex Koller: they can acquire real estate without authorisation, including a secondary residence. An EU/EFTA category B residence permit will generally support such a domicile, as will a category C settlement permit. A short-term residence permit (category L), however, is not on its own sufficient to establish it: a case-by-case assessment is required, and where an acquisition is possible at all, it will only be for a property used as a main residence.
  • Persons domiciled abroad must, barring exceptions, obtain cantonal authorisation to acquire a secondary residence, and are subject to surface restrictions as well as quotas in tourist municipalities, which include Verbier. These exceptions, notably inheritance or acquisition between close family members, are not an exhaustive list and are assessed on a case-by-case basis.
  • Even where no authorisation is required, the land registrar may ask the buyer to have their non-liability under the Lex Koller formally confirmed. This is a confirmation, not an authorisation: the distinction matters, as it is the source of most confusion around this law.
  • Using the property as a secondary residence also remains subject to the federal act on secondary residences (Lex Weber), as well as cantonal and municipal zoning rules.

This legal framework evolves regularly. A revision of the Lex Koller is under way: the Federal Council opened the consultation on 15 April 2026 and closed it on 15 July 2026; it addresses, among other things, a tightening of access for persons abroad and stricter rules for holiday homes. The text is not yet in force. This article describes the state of the law as at its publication date. Its application depends on each individual situation (nationality, residence status, type of property): we systematically recommend having your eligibility confirmed by a notary or the relevant cantonal authorities before making any commitment.

Secondary residences in Verbier: what the Lex Weber changes

Beyond the Lex Koller, acquiring a secondary residence in a tourist municipality is also governed by the federal act on secondary residences (Lex Weber), in force since 2016. Rather than restricting supply in general terms, it specifically targets the creation of new secondary residences: in municipalities where they already exceed 20 % of the housing stock, new secondary residences can generally no longer be built; this is the case in Verbier, where new housing is therefore primarily intended for main residences.

It remains possible to acquire an existing property for use as a secondary residence, but this designated use cannot be assumed: it must be verified case by case, based on the original building permit and the entries in the land registry. We recommend having this point checked before making an offer on any property intended for secondary use.

Swiss property taxation: the key principles

Owning property in Switzerland involves several types of taxation, the rates and terms of which vary considerably from canton to canton, including in Valais:

• Wealth tax, calculated on the property’s taxable value, from which mortgage debt can be deducted. It depends on the canton and the municipality.
• Income tax, which applies to rental income when the property is let, but also, until 31 December 2028, in the form of an imputed rental value for an owner who occupies their own home — a notional income reflecting the benefit of living in one’s own property. Mortgage interest and certain maintenance costs remain deductible under the applicable rules. The abolition of the imputed rental value is scheduled to take effect from 1 January 2029; the reform will also change the deductions available for interest and maintenance, and its effects will depend in particular on how the property is used and on the canton concerned.
• Transfer duties, levied on purchase, generally in the range of around 1 % to just over 3 % of the price, depending on the specifics of the transaction, the canton and the municipality.
• Real estate capital gains tax, due on resale on the profit realised. The scale is degressive: the charge generally decreases with the length of ownership, and the calculation is not reducible to a single rate. In Valais, the gain realised on a main residence may also qualify for a tax deferral where the sale proceeds are reinvested in a new main residence in Switzerland, subject to conditions on the length of occupancy and the reinvestment period.

Given the complexity and regular evolution of these rules, checking with a tax adviser or notary remains essential to assess the precise tax impact of your project, particularly if you reside abroad.

Investing in Verbier: a distinctive mountain market

The Val de Bagnes holds a distinctive position within the Swiss property landscape: accessibility, the 4 Vallées ski area, and an international clientele that has remained loyal for decades. For an investor, this translates into a supply concentrated on high-end chalets and apartments, strong attention to views, orientation and ski access, and an active seasonal rental market.

For context on current market conditions, our article Switzerland Property Prices in 2026: What It Means for Buying in Verbier reviews recent market trends.

These local specifics, combined with Switzerland’s legal and tax framework, make the support of an agency established in Verbier particularly valuable in securing an investment project, whether a first acquisition or an addition to an existing portfolio.

FAQ

What budget should you plan for investing in Swiss real estate?

Beyond the purchase price, you should anticipate at least 20 % in equity (often more for a secondary residence), transfer duties, notary fees and ongoing charges.

Why invest in Verbier rather than elsewhere in Switzerland?

Verbier combines a Swiss property market recognised for its stability with the positioning of an international resort, sustained seasonal rental demand and a supply of high-end properties limited by the mountain geography.

Do you have to pay tax on Swiss property if you do not live there?

Yes: property wealth and, where applicable, rental income generated in Switzerland remain taxable in Switzerland, under rules that vary by canton. Personalised tax advice is recommended.
