Rental market vacancy rates and turnover: a balanced housing market generally portrays a vacancy rate of +/- 3%, but most Swiss towns and cities have a vacancy rate of between 0.2 % and 0.8%. This means that the market is tight and demand is higher than supply. This affects price and the number of available properties. Because there are many international workers in big cities such as Geneva, Zurich and Basel, this causes a transient population, and apartments become available quite frequently. The best time to look for a rental property is between April and early July, as families relocate during the summer holidays. Tenants tend to stay in the same accommodation for much longer than average in other countries.


Is it better to buy or to rent?: Prices have increased significantly in the Swiss property market over the last ten years. Buying in Switzerland does become cheaper than renting over the medium term. Consider the following:
Mortgages can extend up to 100 years
Property ownership is subject to taxation, so consult a tax advisor
A minimum 20% deposit is required. A mortgage broker can assist
You should stay in Switzerland for at least six years to make it worthwhile
