- 50 kEuro via KFW at 1.45 %
- 155 kEuro at 1.34%
- 185 kEuro at 1.91 %.
The loan of 155,000 Euro has a lower interest rate than the KFW loan. Usually, the bank is fully liable for the KfW loan, so why doesn’t it offer 155,000 Euro + 50,000 Euro = 205,000 Euro directly at 1.34 % p.a. effective? More details would be helpful in this regard.
Otherwise, this sounds unbelievably good to me! In autumn 2014, I had a mixed interest rate of about 2.5 % p.a. effective for a somewhat similar situation (very high loan-to-value, used house). Unfortunately, the purchase did not go through ... Well, from the perspective of interest rate development :-).
The higher the income, the less crisis-proof jobs usually are. But maybe you are a civil servant ... In general, I find it at least courageous and would, in the first five years, pay extra on the loan like there’s no tomorrow, to reduce the outstanding debt significantly below the value of the asset. So make sure that sufficient prepayments are possible! As already mentioned, naturally, the most expensive loan should be repaid first!
