Interesting, in which direction my question has developed...
Currently, we set aside 500 euros monthly for the special repayment, plus my 13th salary, which adds up to about 10,000, plus the tax refund. Hence the 10,000 to 14,000 per year. Additionally, 500 euros monthly for reserves. The rest goes to the house, car, insurance, and living expenses. And we are already very careful to buy many things only on sale, as cheaply as possible. At the end of the month, nothing is left over. Therefore, with one child under these conditions, it would already be tight. We would have to reduce either the special repayment or the reserves. Hence also the consideration whether to quickly pay off the car now and then use the money flexibly for the child, or later the special repayment/reserves. Or tighten the belt even more. Continuing to make special repayments on the house now definitely saves a lot of interest....
Thanks for your feedback so far, there are advocates on both sides after all. I think it will be the house, as I (31 years old) am willing to take a bit more risk to save on interest. That’s why we only took out our 100 percent financing for the house for 10 years. Maybe this way of thinking will pay off someday. We’ll see...
