How much house is in it?

Under no circumstances ever ever not jeopardize the parental home! If they have money left over and want to support you, they can give it as a gift (or for all I care also lend it, if that is preferable for everyone involved - although I personally wouldn’t do that). But then it really should end there!

Eyo when parents die, it’s inheritance anyway

€555k loan with €0 equity. Because you want to keep your cash as a buffer.

Should I laugh at you now for being goofy?

Sorry, I have zero understanding for something like that. It seems to me that people are becoming more and more delusional.

Although, under the theoretical assumption that no children arrive, you could do that. That would be, in my view, the only way to manage something like this.

Okay, maybe I expressed that unclearly - registering a land charge on the parents' house does not mean that the entire parents' house is in debt. Only to the amount of the entry. And whether we actually do that, we don't know at the moment. It would just bring a lower interest rate, although we could also live with the higher interest rate.

Personally, I am satisfied with it. I just wanted to post again about how the conversation with the financial advisor went, because it was requested. Whether everyone is okay with it or whether it is classified as reckless/megalomaniac/etc is okay, everyone should have their own opinions

registering a land charge on the parents' house does not mean that the entire parents' house is in debt.

However, with such a land charge, your parents are entering into an obligation. If there are payment disruptions, the bank can enforce the land charge. Then it means putting the money on the table or taking out a loan; otherwise, this collateral will also be realized.

So the bank really has to make quite a concession to you.

Of course, the entire parental home is indebted (or pledged) - you can hardly just sell the fireplace. They probably won’t end up at zero or even below after liquidation, but it will be liquidated if you cannot pay. Or they buy you out with their own funds or a loan. You wouldn’t be able to do that in this situation.
