What this rise concretely means for your monthly payment and principal repayment is laid out by mortgage financing expert Birgit Weber in the current Focus Stars expert check.

This is not some abstract market movement. The rate increase hits directly in the burden coming your way as a property owner – and turns the 2026 follow-up financing into a key financial lever. Anyone planning now must calculate, not estimate.

Rates from 1.5 to 4.2 percent: mortgage financing expert Birgit Weber explains what this concretely means for your follow-up financing and loan payment.

What the rate shock means for your loan payment

The jump from 1.5 to 4.2 percent is more than a number on the rate chart. It shifts the ratio of interest and principal repayment in your monthly bill – and therefore the amount that actually flows toward paying down debt. Weber puts the concrete real-world effects in context in the piece.

Principal repayment and forward loans as levers
