Paying "rent" to the partner... how?

Oh people, this topic is about a money question

The question has already been answered several times. Everything that exceeds half of the interest costs + additional costs is completely at your expense and in his favor.
If you want to build his wealth with your money, then pay more. Otherwise, tell him that you do not want to do that, but that you want a mutually objectively fair arrangement as described above. Period. Why do you have to give in and not him? So that the man can be the man again and be right?

Or simply consider it completely differently, that you take out the loan together and become joint owners. Each with the share they can/want to provide ==> e.g. 1/3 to 2/3, so his equity would also be covered by an increased share in the house and no one would have to pay "rent" for the other.

What still amazes me is this offsetting. He has this, I get that. Or that you wouldn’t live in Stuttgart at all if he didn’t want to go there, so you have to use lower (comparison) rents. Why don’t you allow each other the advantages of living together? I find that incredibly weird, ...

I said that I simply like to calculate such things down to the last cent for MYSELF, not because I ultimately want to settle accounts that way, but because I like to juggle numbers. And now you can continue to find me strange

The question has already been answered several times. Everything beyond half of the interest costs + incidental costs is completely your burden and to his advantage.

I didn’t want to go back to the original question, but only to make clear that this topic logically only concerns money overall. The original question has long been answered, but that doesn’t mean we have to close the thread, does it? Apart from certain below-the-belt remarks, I still find the exchange interesting.

No matter what you do, you have to feel comfortable with it. Are you allowed to have a say in how the house turns out or does the owner decide everything? I know both. With us, it was balanced; with acquaintances, they had no say at all.

As long as you both find a solution that you both consider fair and reasonable, that suits me.

That is indeed a question/a topic that can certainly be resolved with or without compromises. There was enough input and this is still a house building forum and not life advice. I am still looking forward to the final result.

One more question:
Is it certain that he can manage financing on his own? Or does he get one at the bank as a so-called single? Banks prefer couples (even unmarried), because if one defaults, they can still get something from the other.

Let's continue discussing...

I did not want to go back to the initial question, but just to make clear that this topic logically only concerns money overall.

You can clearly see here: whoever has the cash has the power. Either you adapt or...?

By the way, we have 3 accounts
Since we have no children, we both transfer money to the house account. Everything related to the house and property is paid from there. Food expenses come from whoever buys it.
