Fastforrentet lån (fixed-rate mortgage)

A fixed-rate realkredit loan keeps the same rate for the whole term, typically up to 30 years, so your payment is locked regardless of the market rate. The rate is usually higher than a variable loan, but you can convert to a cheaper loan if rates fall and cut your debt if they rise.

The advantage is predictability. You know the payment from day one, and it does not change even if rates rise.

If rates fall later, you can convert down to a new loan at a lower rate. If rates rise, you can convert up: repay the loan below kurs 100 and reduce your outstanding debt. That conversion right is a flexibility a variable loan does not give in the same way.

The price of the security is a slightly higher rate at the start than on a rate-adjustment loan. In return, you never worry about the next rate reset.

A fixed rate suits you especially if you want to know your payment for the whole term and have a tight or newly started budget without a large buffer.
