A foreign buyer who spots a chalet in the Bernese Oberland or an apartment in Verbier faces, even before the price question, a legal framework that can block the entire transaction. Investing in real estate in Switzerland requires mastering specific constraints, from federal regulations to cantonal disparities, as well as financing conditions that differ significantly from those practiced in France or Belgium.
Lex Koller and the anticipated tightening: what the April 2026 consultation changes
The Lex Koller has been regulating the acquisition of real estate by individuals residing abroad for decades. In April 2026, the Federal Council launched a consultation aimed at significantly tightening this framework. The project notably plans to require authorization for the purchase of a primary residence by nationals from third countries residing in Switzerland without a residence permit.
Another concrete point: if the property is no longer used as a primary residence, a resale within two years would be imposed. Thus, we move from a regime where a holder of a B permit could freely buy their primary residence to a potentially more restrictive system.
This tightening does not only concern direct purchases. The proposals examined in 2026 also target shares of Swiss listed real estate companies and certain real estate funds held by individuals abroad. For an investor considering indirect exposure to the Swiss market, regulatory risk now affects indirect investment.

Equity and mortgage rates in Switzerland: financing rules to know
A yield property (rental building, apartment intended for rent) requires a minimum of 25% equity in Switzerland. The use of the 2nd or 3rd pillar is excluded for this type of acquisition, unlike the primary residence where these pension assets can supplement the contribution.
On the rate side, the situation remains particular. The Swiss National Bank has lowered its key interest rate to a very low level, but fixed-rate mortgages have risen despite the zero key rate from the SNB. Banking institutions anticipate a future increase and incorporate this premium into their fixed-rate offers over five or ten years.
Comparing offers between institutions
Rate differences between cantonal banks, major banks, and online brokers can reach several dozen basis points. On a loan of several hundred thousand Swiss francs, the annual difference is not negligible.
- Check the mandatory amortization conditions: in Switzerland, one generally has to repay the mortgage debt below two-thirds of the property’s value within fifteen years
- Distinguish between first-ranking mortgage (up to 65% of the value) and second-ranking mortgage, which has a higher rate
- Request simultaneous offers from at least three institutions to have a concrete negotiation basis
Rental yield in alpine resorts: altitude and infrastructure as sorting criteria
Prices in Swiss alpine resorts do not progress uniformly. The arrival of new transport infrastructure (cable car, rail link) can significantly increase a property’s value in a few years, while a poorly served resort stagnates.
The realistic net yield for a yield property in Switzerland is around 3 to 4%, once operating expenses are deducted. In resorts, returns vary on this point: seasonality affects the occupancy rate, and condominium fees in mountain residences can be high (snow removal, heating, maintenance of common areas).
Double season and occupancy rate
A chalet or apartment located in a resort that operates in summer as well (hiking, mountain biking, events) shows a significantly higher occupancy rate than that of a purely winter resort. Favoring a double-season resort reduces the risk of rental vacancy throughout the year.
Altitude also plays a direct role in the reliability of snow cover. Above 1,800 meters, the ski season is longer and winter rental demand is stronger. Properties located at lower altitudes face increasing pressure due to climate change, which ultimately weighs on their asset value.
Housing shortage and rental tension: the Swiss context in 2026
The monitoring by the Federal Office for Housing published on September 16, 2026, confirms that the supply of housing remains insufficient in the face of the growth in the number of households. This tension does not only concern large cities: several mountain regions are also affected.
A rapid relaxation is not expected. A more marked recovery in construction is anticipated starting in 2027. For an investor, this shortage supports rents in the short term, but it also means that finding a property to acquire takes longer and that competition among buyers drives up entry prices.
What this implies for a rental purchase project
- The average rent multiplier in Switzerland is around 25: the lower it is, the more interesting the property is in terms of yield
- In tight areas, rental vacancy is almost zero, which secures income but compresses gross yields
- New construction projects in the mountains are hindered by land use constraints (law on secondary residences, protected areas), limiting future supply
Taxation adds a layer of complexity. Tax rules vary from canton to canton, both for the taxation of imputed rental value and for the treatment of property income. A rental apartment in the canton of Vaud and a chalet in Graubünden do not generate the same tax burden, even with identical gross yields.
Before signing a purchase agreement, it is advisable to save time by having a local fiduciary simulate the cantonal tax burden. This item is often underestimated by foreign investors, who are used to a uniform national tax system.
