How would you finance €340,000? Split it?

I also said that I want an offer for a regular loan of 340,000€ with a 15-year fixed interest period.

Well, with that rate, after the fixed interest period of 15 years, you will still have over 200,000€ remaining debt. Without knowing your financial background, it’s hard to say much about it. But you need to be aware that interest rate increases can become really expensive for you. The follow-up rate can quickly be 500€ higher per month. If things go badly, you might not even get that as a loan because the bank must check according to the residential loan directive whether you are able to bear an interest increase after the fixed interest period. And this check is based on the current income circumstances or what is known today. That’s why see my previous post... For a 15-year fixed interest period, the repayment rate would be too low for me and thus the remaining debt too high. (Unless you have such a good income that you can easily handle it and can afford to speculate that interest rates will not rise)

Is not recommended for combination products

Not necessarily. In many cases, they can also be sensible. However, they are often expensive and very difficult to compare due to their design.

€100,000 for 30 years €120,000 for 20 years €120,000 for 15 years

And how are the 3 blocks amortized? Evenly? Or how is the weighting?

Or do you think this caution is unwarranted and it’s enough to fix everything at 15 years?

No way

With the Spaßkasse you don’t get a fixed 30-year interest rate. And if at all, only with combo products

Depends on the Sparkasse. Most don’t, but there are a few scattered around the country.

Is it advised against combo products?

You always have to compare the costs. Usually combo products from one source (like e.g. Sparkasse & LBS) are too expensive.

According to the calculations of [Sparkasse], as of NOW we would be approved for a monthly repayment of €1800 with 2 car loans that cost €680 per month. So our incomes don’t seem to be that bad.

However, we would prefer not to commit ourselves to such a high monthly amount, but rather make use of the topic of [Sondertilgung]. This is 5% annually.

How the blocks are repaid I do not know yet. This will become clear in the offers.

It all seems a bit fishy to me. Now add another €680 car loan... Can't you add it as your net income? Otherwise, it's really difficult to assess.

Put the highest possible repayment into the short-term loan. Repay the rest at 1%. After 15 years, the then available

We would rather not commit ourselves so highly on a monthly basis, but rather make use of the special repayment option. This is 5% annually.

... is actually only exercised by a very small portion of those entitled. There are always good reasons to spend the money on other things.

I rather advise forced savings = high repayment as well as a possible repayment change.
