Special repayments or investing in the market? Alternatives?

Yes, I have. A so-called fee-based advisor. A good feeling to pay directly myself instead of always having the feeling that the advisor is guided by the commission. I had all contracts reviewed and concluded a net contract for retirement provision.

Hmm, so if you don't need the money in 15 years, it doesn't matter if it's gone then, and the remaining debt is still manageable depending on the age... then Go for it

But if not:

I mean, here it is assumed that such an ETF always performs positively on average.... People thought that about Telekom back then too....

But it can also crash sometimes.

Have you ever consulted an independent advisor and do you have tips on how to find someone?

I work without an advisor, but exchange ideas a lot with others and like to follow society, politics, and economics. I make many mistakes, some pay off. Ultimately, the individual positions don't matter, but the overall result does, and I am quite satisfied with that. I am skeptical of advisors because I know too much about commission systems and conflicts of interest. Surely there are very good ones, I do not rule that out. I prefer to take full responsibility myself. I am not suitable as an advisor, that would be unprofessional. Therefore, "please do not imitate."

We also prefer an ETF savings plan over [SoTil].

Even if the market is doing poorly at the time the fixed interest period ends, you can simply take out a new fixed interest rate and continue financing.

In addition, this way you hedge yourself with counter-cyclical investments.

If we are in a recession at the end of the fixed interest period in 10/15 years, the probability is very high that the interest rate level is low, and you can continue financing cheaply.

On the other hand, if there is a boom and the interest rate level is correspondingly high, a profitable sale of the ETF and a final [SoTil] are possible.

We have set all our repayment rates as low as possible and initially invest €750 and later €1,500 per month in the MSCI World.

If you have a healthy attitude towards risk, you will do quite well with this strategy.

Of course, you can also mix and, for example, allocate 60% of the surplus to annual [SoTil] and the rest to an ETF savings plan.

That's exactly what I find so dangerous. You're not gambling with play money that you have anyway. And if the MSCI World is so great, then I'll take everything I have now, throw it in there, and never have to work again (-;

What I mean is that it's not that easy after all.

Telekom is a single company while the MSCI World consists of, for example, 1600 companies. There is also the Vanguard ETF, which includes 4000 companies and is therefore even more broadly diversified. ETFs are quite a "safe" investment; you won’t make huge leaps with them, but you can achieve a good return over time. Of course, you shouldn’t need the money at that time...

I wouldn’t dare to do that. In my case, the outstanding debt after 20 years would simply be far too high. In general, due to the compound interest effect, it would be very lucrative.
