Mortgage
A Mortgage is a loan for the purchase or construction of real estate in Switzerland, with the property serving as collateral. Mortgages can be arranged directly with a mortgage provider or through mortgage platforms. HYPOTHEKE.ch is the largest online mortgage platform. The main types of mortgages in Switzerland are as follows: Fixed-rate mortgage,SARON mortgage
Forward Surcharge on Mortgages
A forward surcharge is an additional fee added to the Mortgage interest when a Fixed-rate mortgage is taken out before its actual start date. Mortgage lenders lock in the interest rate for the future and charge a surcharge in return. The amount of the forward premium depends on the provider and the time remaining until the Mortgage begins. Taking out a Mortgage early can make sense if rising mortgage interest rates are expected or if you want planning certainty. The forward premium is related to the Mortgage yield curve. The steeper the current curve, the higher the premium.

No. You can only switch after the term has expired or after giving notice—or with flexible models such as a with no fixed term.
Most lenders do not require a notice period for fixed-term mortgages. However, there are exceptions. Therefore, be sure to review the contract with your mortgage lender.
In this case, there are usually only two options: either temporarily settle for an expensive stopgap solution such as a —or stay with your current provider.
This can cost several thousand francs extra. Be sure to talk to the mortgage lender, though. Since notice periods are rather rare, some mortgage lenders turn a blind eye and “let you go ahead anyway.” However, you’re relying on the mortgage lender’s goodwill.

Caution
Notice periods for fixed-rate mortgages
Some fixed-rate mortgages have cancellation periods—while this is rare, it can become a critical issue. Anyone who misses the deadline risks an automatic extension or an expensive interim solution. It is therefore advisable to review the contract at least 12 months before it expires. For providers with cancellation periods, it’s worth submitting the cancellation notice immediately after signing the contract and obtaining written confirmation.
Not very flexible at all
Replacement of a SARON Mortgage
SARON mortgages appear flexible, but they often come with with terms ranging from two to five years. During this period, you cannot switch providers. Therefore, check whether your SARON mortgage includes such a minimum term. If so, you can switch providers—just as with a Fixed-rate mortgage—at the end of the contract term, typically 12 to 18 months before the framework term expires.
Important Practical Tip
Avoid / Plan for Staggered Payments
People who hold multiple mortgages with different terms often run into a problem when switching providers: Large gaps between the maturity dates make it difficult or impossible to switch to a new provider.
Rule of thumb for a smooth switch to a new provider:
- Deferred payments for up to 12 months → no problem
- Installment plan up to 18 months → usually possible
- Installment plan over 24 months → rather difficult
Consequence of an excessively long amortization schedule: You are tied to the lender—and lose bargaining power when renewing the installments that come due early.

Flexible or Risky
Take out a SARON loan and switch to a Fixed-rate mortgage later
Those who start with SARON and later want to switch to a Fixed-rate mortgage often find themselves in a bind: The switch is usually only possible with the same provider—with little and, consequently, less favorable terms.
Competition in the Swiss mortgage market arises when banks, insurance companies, Pension funds, investment foundations, and other mortgage lenders compete for the same customers. The more transparent the market is, the stronger this competition becomes. HYPOTHEKE.ch capitalizes on this by ensuring transparency and collaborating with all major mortgage lenders in Switzerland.
