Building Savings-Based Bank Loan

The bank loan is designed to fully utilize the 1A conditions.
I just don’t know if 4.29% is really good, but based on the offers I’ve seen so far, it fits quite well.

It is a KFW 124 loan, we had initially planned for KFW 70, but since we don’t want underfloor heating, a heat pump is almost ruled out as an option, and without that, in no opinion is the effort to qualify for KFW 70 greater than the benefit.
The KFW loan runs with a repayment rate of just under 6%, so after 10 years a little more than 20,000 EUR remain. I think we can still save that up in 10 years, or if there is a remainder, it can be refinanced. That should not be a problem because then the first part of the monthly burden will drop off.

Repayment

After the repayment-free start years have expired, you pay back your loan in equal quarterly installments (annuities).
Prepayment

Unfortunately, prepayment is not possible. In individual cases, you can repay the entire outstanding loan amount in consultation with KfW against a prepayment penalty.

I don’t know if the repayment for KFW124 is fixed by the choice of total term of 20 or 35 years, the minimum number of repayment-free years of 1, and the level of the loan interest rate.

A freely negotiable repayment rate of KfW 2; 3; 4; or 6% does not exist to my knowledge.
Kind regards

sorry, but the formatting of the KfW content was lost

The 4.29% for 15 years is currently very good.

Hello Quirinus (wasn't he once a governor of Rome?)

Could be, but he was once a great-uncle of mine and I somehow find the name quite original.

That has also caught my attention, maybe a different KfW program is meant since it was not explicitly stated in the financing offer, I just inferred it from the maximum amount.
The nominal interest rate in my offer is 3.9% - that doesn't quite match either. Otherwise, quarterly payments and no other special repayment options fit again.

I think I will first call my bank advisor on Monday to discuss everything again.
