Ok. That means if I want to secure the 1.31% (instead of 1.51%), I have to fully repay the 100,000€ in 20 years.
That means I end up somewhere around a monthly rate of approximately 495€ with the KfW.
- 100,000 €
- 5,000 KFW 55 repayment subsidy 9 months after completion
- 20 years fixed interest rate 1.31%
- 20 years term (full repayment)
- only 1 year repayment-free (with 2 or 3 years the rate would increase even more to fully repay)
If the nearly 500€ rate for the KfW leaves me not enough for a 3.00% repayment rate on the main loan (173,000€) monthly, I either have to accept the interest surcharge for repayment rates <3% there or increase my budget for the total rate, in other words move to the upper end of the comfort zone.
That should be possible but I would have preferred a total rate lower by 100€ and then possibly make special repayments (up to 5% on the main loan included).
I will ask the bank how high the interest surcharge is if we have, for example, only a 2.5% repayment rate. Maybe the surcharge isn’t that much.
