Bullet loans & annuity loans combined - sensible?

Regarding your special repayment. Just try using a mortgage calculator.

I calculated once:
350K loan, fixed for 15 years at 1.00%
Rate 1400€
7K special repayment each in the first 8 years

results in:
Remaining debt after 15 years 72.7K
Full repayment after 19 years, 4 months
Interest over the entire term 30.7K (assuming a constant interest rate in the last 4 years)

Since we are taking the loan together and only one person will make the special repayment, it wouldn't be such a good solution, or it would make things more complicated.

Hello team,

we have received an offer from a small, local bank for financing our new build in 97421. Here are the details:

Total volume: €550,000
Loan needed: €350,000
The rest is equity (land already paid - €86,000) as well as cash funds.
The new build is a self-occupied single-family house built to KFW55 standard.

Our wish is to secure the low interest rates for as long as possible, to have a special repayment of >=5%, and to have a monthly burden of €1,400 under normal circumstances. Currently, we assume that we can make special repayments (see annuity loan below).

We were offered a structure consisting of 3 different contracts:
1. Bullet loan €100,000 based on KfW credit with 0.75% interest + Schwäbisch Hall building savings contract.
16 years and 7 months. Fixed effective annual interest rate for the entire structure: 1.18%.

2. Bullet loan €150,000 based on Schwäbisch Hall building savings contract.
Term: 21 years and 3 months. Fixed effective annual interest rate for the entire structure: 0.97%.

3. Annuity loan €100,000 including 10% special repayment.
Term: 9 years and 5 months. Fixed effective annual interest rate for the entire structure: 1.57%.

The total costs for all three contracts with a maximum term of 21 years and 3 months amount to €35,003.77. After this time, the €350,000 will be paid off.
Provision interest is waived for 12 months on all three contracts without extra interest.

My questions to you:
- The structure of 3 contracts with different terms and repayment amounts seems somewhat confusing to me. However, at first glance, all our wishes can be fulfilled and after 10 years I can refinance or pay off any contract, right?
- Can someone find a comparable annuity loan that offers similar conditions at our values (total costs, interest rate security) – according to our repayment plan it should have an interest rate of 0.95%, which has not been offered to us yet.
- Other assessments?

Thank you very much!
