It doesn't work without equity - experience!

neither much equity nor a great loan-to-value ratio

Well, there was a time when, under ideal conditions, financing at < 1% p.a. nominal over 10 years was possible. If you then add some premiums for the long fixed interest rate and the high loan-to-value ratio ... < 2% is still amazingly cheap in my opinion. Congratulations!

Our advantage was that I can carry the life and the (quite high, if you read the other threads) rate alone.

But the way it sounds, it also means that if you can't go on anymore, it's over. Whether that's really an advantage is questionable.

It's like that in the vast majority of cases...and nothing new.

Exactly, in which families with children can both parents pay off the house? But that's what you secure yourself for accordingly.

That’s what I meant. It’s simply a risk and therefore should not be positively reflected in the loan conditions. To my knowledge, one-sided dependence on just one major customer is rather a negative factor in a company’s rating.
Perhaps one of the bankers can provide information on whether there is an impact on the loan conditions depending on which partner contributes which income. But I doubt that.

One-sided dependence on only one major customer is, to my knowledge, rather a negative factor in company ratings.

Who said that my wife couldn’t cover the rate if she started working again? At the moment, the parental allowance could completely disappear and we could still live. If my wife worked even part-time, we would be covered by the disability insurance (BUZ) in case of occupational disability. There are relatively few cases in which the financing would no longer be sustainable. When I look at other financings here, where both partners earn almost the same amount, I actually see it as an advantage if one really has 0€ per month.
