Hello everyone, thank you very much for the constructive contributions :)
After the note about the overall significantly higher total interest burden in the context of the 35-year fixed interest period, we have now requested further offers with an interest fixation of 20 years; a shorter period is definitely too risky for us, our considerations exactly match those of stonan. We had not thought of the idea with the non-repayment start years of the KfW portions until now, but find it very interesting at first glance! Especially since the total sum of 100,000 euros with these two loans should still be somewhat repayable even with a significant interest increase after 10 years, and in the first years, of course, as mentioned, we could repay the more expensive main loan faster. We will calculate that in detail right away! Does anyone see a catch???
The nominal interest rates are as follows:
Main loan (296,000 euros) -> nominal interest rate 3.87%, repayment rate 1.43%
Component 2 (KfW 153, 50,000 E) -> nominal interest rate 1.9%, repayment rate 2.59%
Component 3 (KFW 124, 50,000 E) -> nominal interest rate 2.75%, repayment rate 1.78%
