Financing - Special Termination and Deadlines

one more note:

of course, if you refinance in 2023/2024 or even 2025, you pay interest surcharges on current conditions.

BUT
if, for example, I pay a 0.20% interest surcharge for the KfW loan, and 0.40-0.50% on the main financing, it would probably still be cheaper than waiting 1-2-3 years.
Why?

Interest rates have risen by about 0.35-0.50% in the past few months... what will it look like in 1-2 years?

if you do nothing now, the interest rate may increase by 0.20% in 1 year, and by 0.50% in 2-3 years
then we would be at 0.00 difference (so it would not matter whether you do it now or in 1-3 years)

but what if the interest rate is 0.50% higher in 1 year? (then the 0.20% interest surcharge would still be cheaper)
and 0.75-1.00% higher in 2-3 years?

what is more likely? that the average interest rate falls from 1.00% to 0.50% or rises to 1.50%? in the near future?
Sure, no crystal ball, so no one can predict exactly... but a little probability calculation helps here.

Maybe as an addition for all credit seekers. Banks will have to maintain the "countercyclical capital buffer," which was reduced to 0%, at 0.75% in the future. Simplified German: capital reserves for loans. And thus loans cost banks quite a bit more than before. And this will ultimately lead to another surcharge on the interest rate level. And Basel 3 will also burden banks from 2023 onwards and lead to more expensive credit. Both points independent of all other developments in the markets.

Maybe as a supplement for all credit seekers. Banks will have to comply with the "countercyclical capital buffer" reduced to 0% in the future at 0.75%.

For residential real estate, there is still an additional buffer of 2% - because there are absolutely no bubbles, they probably want to apply the brakes a bit more..
