Is my house building plan realistic?

So I cannot understand this statement, i.e. someone who is good at saving would have more difficulty paying off a loan than someone who never managed to save anything before?

No, that is not what is meant. You have a high standard of living and still save, as all the (annoying) additional costs are not yet present. When you then have your own place, it can be very frustrating to watch the money disappear for something you have no connection to yet (garbage, electricity, insurance, ...).

So elsewhere they say you can plan up to 1/3 of your salary for loan repayment, so why should 1/4 be too much for me? How much do you have to earn to pay off 1170 per month? If I move into an apartment, then I pay about 1000€ for a family as well. I mean, I’m really grateful for the advice, but I can’t quite understand it...

I do think it could work. €1200 would be a 4% annuity, which is of course not much - better plan with €1500 and then see what concrete offers you get. Do you really think your house needs to be 200 m² - you don’t even have a child yet - how many are you planning? €420k is quite a lot for a house.

Yes, I’ve already reduced the 200 m² to 180 m² anyway. Two children are planned and in my opinion, you need that amount of space for that. I myself grew up in a 200 m² house and in our village almost all houses are that size. As I said before, living costs are also lower here than in a big city. When I hear that some people pay €600-800 for daycare, those are costs we will never have.

Since we ourselves are building 190 m² with two children, I don't want to say anything against that. We are very much looking forward to the craft and playroom. I would keep €20,000 in reserve so that you can bridge up to 2 years in case of your wife's loss of income. Furthermore, I would get a few non-binding offers from large expensive GÜs [Generalunternehmer], so that you already have a ballpark figure (everything else is groping in the dark).

We have an offer from an acquaintance who built something similar a few months ago, as we plan to do, so I can already roughly estimate the pure building costs. What will be added for house equipment (appliances, etc.) is still a small question mark?
