Thank you for the further answers. It is also about calming my emotional wife a bit, who would prefer to buy tomorrow.
We have 2 workplaces far apart, so the potential place to live is quite limited and this would at least fit there. But the rest not really. Too expensive in itself, then logically having to invest something, not the most energy efficient, etc.
What happens from the banks' and scoring perspective if I am completely debt-free and only have a car lease running, which I think will always be ongoing anyway, I nowadays no longer really see a car as debt, even if many see it differently. It should always have roughly the same value as the remaining loan, so that the outstanding amount and the value neutralize each other.
Is one then still worse off in scoring because one had loans or even better because it shows that one has always paid everything off without problems?
A buddy bought a 130k house, has to have it completely renovated, got a 200k loan, only one income and also many small loans... that probably blinded me a bit. I don’t really want to pay more than 2k at the moment for outstanding loans and probably even less income if another child comes.
Although I don’t know whether one should then buy something cheaper, maybe something new, significantly smaller around a total sum of 300k or even less, or pay off first plus ideally build equity and then buy something bigger later. But I think it will come down to number 1. Maybe pay everything off completely now, then there would only be BAföG from my wife at some point (I think that is not scoring relevant, right?), so that one takes a cheaper loan without equity but also without debts and just lives smaller...
