Fortunately, we still have old RV. I think 2.75 or 3%.
You can only dream about that today.
I was also torn back and forth regarding the BU... after all, a lot of money. But I have two family members myself who would both be renting again today without this insurance.
Regarding childcare: we are lucky to only have to pay 400 €. In Karlsruhe, we would have had to pay almost 750 €, with absolute uncertainty about getting a spot at all.
In the Palatinate, we have to bridge one year, since from the second year of life every child is allowed to attend kindergarten, and that for free.
So that puts it into perspective.
But one should not lose sight of such costs.
One addition I have: If you receive parental allowance, and it is somewhat higher than 1000 € per month, you should URGENTLY set aside about 200 € monthly for this year. The tax repayment is not insignificant. Fortunately for us only 2000 €, but for friends they have to repay 4000 € just like that.
