The one-third rule: how much can I pay for a property?

3 min read

The Swiss mortgage system has very specific rules you need to know.

The two fundamental criteria

Minimum 20% own funds: Banks require at least 20% of the purchase price as equity (10% must be liquid).

The one-third rule: Total mortgage costs must not exceed one third of your gross annual income.

Types of mortgages

Fixed-rate mortgage: Fixed rate for 1-15 years. Security and predictability.

Variable mortgage (SARON): Varies with the Swiss money market. More flexible but with uncertainty.
