Special repayment, saving or consumption?

If I have an interest rate lock-in of 30 years, I can practically (as soon as the 10 years have passed) repay the loan at any time WITHOUT prepayment penalty, correct?

As far as I know, yes.

I have a 15-year fixed rate and if the interest rates are still low in 9 years, then I cancel the contract and enter into a new one with 15 years again. If the interest rates are higher in 9 years or are too high for me, I just gamble a bit. It can also go wrong and the interest rates continue to rise until the end of the 15 years... then I just had bad luck.

I have a 15-year fixed rate, and if the interest rates are still low in 9 years, then I will cancel the contract and sign up again for 15 years. If the interest rates are higher in 9 years or too high for me, I’ll gamble a bit more. That can also go wrong and the interest rates keep rising until the end of the 15 years... then I just got unlucky.

Perfect, then I was right after all!

In February, this offer from the Münchener Hypothekenbank should come again, which we are speculating on... I pay 15, take 30 years fixed interest. Then it makes perfect sense for us, especially if we can cancel at any time after 10 years anyway.

We then make a "higher" amount with the 30 years (costs of 15 years) and the rest just over 10 years.

How does it work with the KFW loan? Can I also pay it off after 10 years? In other words, could I completely repay the loan after 10 years with a single payment (of course considering the notice period)??

I'm not sure, but I think the KFW loan must even be repaid within 10 years. Or were the 10 years just the maximum ZB? I don't know right now, sorry

edit: on the KFW website it says the maximum term is 30 years.

I'm not sure, but I think the KFW loan actually has to be repaid within 10 years.

As far as I can see, I can also specify a term of 30 years with 0.95%. But since the interest rate is fixed for only 10 years anyway and is not particularly good, I can of course let the loan run with a term of 10 years, pocket the €18,000, and then refinance immediately, preferably together with the other 10-year contract that I will conclude.

yes, just found it too

Such a split only makes sense if the inheritance is certain or if you can pay off the loans through special repayments during/after the fixed interest period. Otherwise, you will never get rid of the one bank.

We have such a split 20,15,10 and the plan currently works out after 22 months of repayment and special repayment, so that the 10 one is paid off in 4-5 years with €100k through any special repayment and the 15 one (no special repayment possible) is paid off after 8 years with €50k. Depending on the interest rates in 8 years, we either let the large one run or reduce the repayment and increase the special repayment.
