Change repayment rate - bank now requires new documents

I can only tell you how we as a bank handle it.

1. Pay close attention to the definition according to the loan agreement and/or supplementary conditions. For loans above 80% LTV, we go down to a maximum of 2%.
2. A credit check is not conducted when changing the repayment rate. There should also be no basis for this in the ADBs/AGBs, which are roughly the same at all banks.
==> with us, just simply request it and we will implement it as agreed without further examination - whether up or down

I would simply ask your bank where it says that a credit check is necessary for changing the repayment rate. In my opinion, it probably does not say anywhere and the bank would not care either, unless it is agreed upon.
And otherwise, if the creditworthiness has not changed, just provide the bank with the documents. And even if the creditworthiness is a bit worse, absolutely nothing will happen. In almost 30 years, I have not seen a single penalty measure due to a change in creditworthiness, as long as the installments are paid. You can be completely relaxed.

And I fully understand your approach as well. If I have an interest rate of 1% on the financing, I would also rather invest my monthly repayment in a savings account. And then, when the investment interest rate is below the loan interest rate again, I would increase the repayment accordingly. A clever approach with which you can save money. You won't get rich, but it will certainly make a noticeable difference (over the term).

But apparently he does not. Or are you advising him to pay only interest and rely solely on special repayments? That’s nonsense, he can do that anyway, as he says. what is your interest rate?

Very interesting insight from you, thank you!

Actually about 1.28% effective.

And yes. I advise him to reduce the repayment as much as possible and not to rely on special repayments, but rather on parallel savings until the fixed interest period ends. Alternatively, until the investment interest rates fall below his loan interest rate again. From a business perspective, this is the only correct decision. Why should he repay his loan if he has an interest rate difference of 2.5% + x? He then reduces his debt more than twice as fast. Therefore, dear ypg, it is your statement that’s nonsense, not mine.

But approximately, it is 1.28% effective.

So you are the one who already asked this question yesterday/the day before in another forum?
If yes, then you must have followed some calculations there as well ;)

In this respect dear ypg, your statement is nonsense, not mine.

You are always right anyway! :)

If yes, then you must have also been able to follow some calculations there ;)

No, that is actually a coincidence, I am only in this forum and just saw the message in the mailbox today!

Was it about a similar matter there?
