Frequently Asked Questions

What is follow-up financing?

Follow-up financing is needed when the fixed-rate period of your mortgage ends but the loan is not fully repaid. You can negotiate new terms with your current bank (prolongation) or switch to another lender.

When should I start planning follow-up financing?

Start 12-36 months before your fixed-rate period ends. This gives you time to compare offers and possibly secure favorable rates via a forward loan if rates are attractive.

What is the Follow-up Financing Calculator?

The follow-on financing calculator compares prolongation, refinancing and forward loans for continuing a mortgage after the fixed-rate period ends.

How does the Follow-up Financing Calculator work?
