Forward Mortgage: When it Makes Sense to Lock in Interest Rates up to 24 Months in Advance

The Principle of Forward Interest Rate Fixing

A forward mortgage is essentially a fixed-rate mortgage, but its term does not begin until a later, agreed-upon date. You sign the contract today, but the payout takes place in the future—depending on the provider, up to 24 months in advance. For this service and the risk the bank takes by reserving the capital, a so-called forward premium is charged on top of the current interest rate. This surcharge increases the further in advance the start date of the mortgage is.

Weighing Planning Security Against Interest Surcharges

Deciding on fixing a rate in advance is always a bet on future market developments and requires a careful analysis of your own risk tolerance.

• Protection against rising rates: If you expect interest rates to rise significantly in the coming months, a forward mortgage can lower the total cost of your financing considerably by locking in today's level.
• Cost of security: The forward premium means you pay a bit more today than if the mortgage started immediately. If rates fall contrary to your expectation by the start date, you are still tied to the contractually agreed higher interest rate.

Strategic Integration into Follow-Up Financing

Forward mortgages are especially a popular tool for expiring fixed-rate mortgages. Many property owners underestimate that they do not have to wait until the very last day to negotiate an extension with their bank or a new institution. By locking in the rate early, you avoid the stress shortly before the end of the loan period and eliminate the risk of a spike in interest rates at the worst possible moment.

With a forward mortgage, banks check affordability already at the time the contract is signed. Because the interest rate including the premium is fixed, the calculation basis remains stable. This is particularly beneficial if it is foreseeable that your personal income situation could change before the mortgage starts, for example due to a career break or transitioning into retirement.

Who Benefits from Locking in Advance?

A forward mortgage is primarily worthwhile for security-oriented homeowners who need a clearly defined budget and do not want any surprises regarding interest payments. Those with sufficient financial reserves to cushion higher rates often benefit more from waiting or a SARON mortgage. However, in a volatile market environment, locking in a future rate provides valuable insurance against unforeseen cost jumps in housing.
