Building / buying a house under the circumstances possible?

Yes, one should answer specifically asked questions in the forum, otherwise exactly what is happening now will happen: 12 pages of blah blah blah, chewing over the same thing 100 times and still not getting to the point

I'll start and wish the OP much success with her decision, I'm out

So? Are you only allowed to answer specific questions in a forum? And doesn't it have a considerable amount to do with finances when the huge investment in a house actually doesn't fully match one's own needs? Someone who invests hundreds of thousands of euros not in their own house but in nice vacations, good food, wild parties, fast cars or the like and maintains the local freedom of a tenant life may not necessarily be the unhappier person at the end of the day.

After all, Bonnie Ham has repeatedly posted in trouble.

First they pay cash for cars, then we see a car loan for a friend's car that the girlfriend doesn't really understand how it works or what he's up to.

Sorry, if you want to buy a house, the finances should be organized and clarified. Just yesterday at a barbecue I heard a story. Life partners build a house, the woman is pregnant, the boyfriend cheats. Boom, over and done, the woman moves out, new girlfriend moves into the new house.

No, just the naked truth. People can’t handle criticism. They prefer only positive things with bows. But be that as it may, OP should do it. The economy also needs a few distressed loans. Notaries and lawyers want to earn money too.

You, I handle criticism or critical remarks well. I think that could also be seen quite clearly here, there were quite a few who asked more precisely. I am always grateful for suggestions and inquiries. Only you took it to a personal level by advising me to think about my relationship (!) and your following post also shows that you apparently only skimmed through my posts:

First they pay cars in cash, then we see an auto loan from a car of the friend of those whose girlfriend doesn’t really know how that works or what he’s up to.

- From the beginning I clearly said that
a) I paid for my car in cash, but
b) my FRIEND did not
- Each of us has exactly one car
- I have known that his car is financed since I have known him
- I also know how it "works" – what is there not to understand? I know the contract, I see the withdrawals.

All this is already stated in the first post with which I opened this thread. You just have to read carefully. Among other things it says there:
"- Auto loan 240 € (the other car is paid off)"

However, I sometimes also have difficulties with your wording, maybe that’s where our misunderstandings come from.
"from a car of the friend of those the girlfriend doesn’t really know how that works" -> that is just hard-to-understand German.

Especially since the story about his acquaintance's love life really has nothing to do with "if you want to buy a house, the finances should be organized and settled."

I see your project very negatively. Sorry. I see deficits in the financial area. Does your boyfriend know your plans for the property and does he want it too? Why boyfriend and not yet husband? These are fundamental matters.

What do you think, please? That I am thinking about this all alone and he has no idea? That I looked at the house by myself? That I had someone from Dr. Klein at our home alone and he was consciously locked up unconscious in the basement at the time?

"Why boyfriend and not yet husband" - apart from the fact that the "why" is once again an presumptuous and quite personal question (questions that other thread starters don’t seem to be asked here), I have already written something about that in the first post.

"Why boyfriend and not husband" – apart from the fact that the "why" is once again an arrogant and quite personal question (questions that other thread starters here somehow are not asked), I already wrote something about this in the first post.

Oh right, then everything is fine. Dr. Klein is a good broker. So finance it.
