Is a bullet loan and ETF currently worth considering?

Currently, due to the low interest rates, corresponding construction financing can be obtained cheaply.

What speaks against, for example, handling a partial amount of the construction financing through a bullet loan, and investing the actual repayment rate in ETFs or in a fund savings plan over the term?

For example, running €50,000 over 10-20 years as a bullet loan, which is already secured via an old capital life insurance contract concluded before 2000 and accordingly "safe". And investing the saved repayment of, for example, €200 in an ETF/fund savings plan?

It is somewhat a 50/50 bet, but since the bullet loan is basically already secured now, and the life insurance would still run for 20 years, the risks would be manageable?

For example, €50,000 over 10-20 years as a bullet loan which is currently already running via an old endowment life insurance policy concluded before 2000 and thus would be considered "safe". And to invest the saved repayment of, for example, €200, into an ETF/fund savings plan?

It’s kind of a 50/50 bet, but since the bullet loan is basically already secured, and the life insurance would still run for 20 years, the risks should be manageable, right?

It’s just a bet that many banks won’t enter into with you together. Nothing is secured yet. Has the tax issue regarding the partial surrender against the life insurance, as you initially suggest, been clarified?
Also, if you would normally repay 2%, you would probably have to put the equivalent of 4-6% into the savings plan for the bank to cooperate. The reason is the low recognition of securities. If that’s okay for you, talk to your house bank – it’s unlikely to work via the internet.

independent of my predecessor... I see another problem. You need the money on the key date X. On this key date, things could look good or bad. It can continue to go well all these years and then suddenly, only half is left (the opposite is also true). In the last 10 years, every monkey has made money with ETFs.... do you have the necessary background or do you trust a community?

No, it’s just a thought as I said, the loan itself would already be secured through an LV. Of course, the bank wants that.

Regarding options for special repayments, it would basically be an annuity loan. I’m just wondering whether, if there’s extra money, one should reduce it through special repayments. Or whether to take the gamble and invest.

You’re not going to get rich with it, that’s clear and I don’t expect that either. The goal is to stay flexible and ideally even make a little profit.

Flexible for me means that the money I put into the ETF/savings plan is accessible again if I want. Assuming the thing makes a profit.

The gamble would be that I take a risk, maybe make a little profit or break even. Or it goes wrong, I make a loss, have to pull the plug at some point, and the consequence would be having to cover everything with the capital payout from the LV.

There are also savings plans nowadays that are conservative and offer deposit protection?

But as I said, it’s currently just probably a dumb thought.

For example, take a look at the Dax prices over the last decades:
- 1993: 2400 points
- 2000: 7500 points
- 2003: 2500 points
After that, it went up significantly again, but what would you do if you had the [loan] maturing in 2003?

I do like some risk here and there, but with all the trade wars and other tensions, the stock market has been very unpleasant lately.

No, it's just a thought as I said, the loan itself would already be secured by a life insurance policy.

New loan with suspended repayment against life insurance? Owner-occupied or rented out? Nowadays, hardly anyone does that anymore, especially owner-occupied is nonsense. Is the maturity amount sufficient for repayment? As I said, watch out for taxes. Otherwise, invest your money as you like. You could also finance another property with the saved repayments, which will then eventually pay for itself. Or you buy gold. Or luxury watches. Or....
