I have now obtained an offer from a bank. They would lend us a total of 270,000 euros without equity (so 110%) at an interest rate of 4.05%, 2% repayment, and 5% prepayment option per year. According to their calculation, this would be a monthly rate of 1361 euros. The remaining debt would be 158,000 euros. But that would also be the maximum they would do. So it really seems quite easy to get the money. There would be 1623 left for living expenses, subtracting 300 for additional costs leaves 1323 for everything to live on. 400 euros already go to food for a family of three, leaving only 923 for fuel for two cars, which easily costs another 300 euros per month, leaving 623 for phone and television, which with the TV license (GEZ) also uses about 100 euros, leaving 523. Since we don’t want to run around naked in the bushes, we also need clothes, especially for the little one who is growing and already needs 100 euros alone, we tend to be ragged and 50 each is enough, which adds another 200 on the minus side, leaving 323 for which I still have to insure us with the most basic things, car insurance 2 times 40 gone, left 243, household insurance 30 gone, 233, legal protection 10 euros 223 left, then the little one also has to pay for daycare, meals etc., later school still another 100 euros gone, rest 123. Retirement provision would have to be suspended, the 240 euros would no longer be possible. If anyone notices something essential for living that I have not listed, please say so. But in my opinion, in theory, it would be barely possible to manage the thing without equity, but it would be highly risky since there would be absolutely no reserves and retirement provision would additionally be reduced. If it goes wrong, you have no house in old age, rent to pay, and only a small additional pension to the statutory one. So I would rather not want to build like that. Now let’s include equity to reduce interest and rate. I have a question because we do not know how banks view equity. 12,000 euros in overnight money accounts/savings books should clearly be equity. Unit-linked life/pension insurance where 20,000 euros are already in there that you would get upon cancellation/sale. 5,000 euros in a building savings contract that is fully paid up, but I do not have the contract here (unfortunately it is at home) because of building savings contract loan. The question is, do I now also have 37,000 euros equity if I do not use it for building? We want to keep it as reserve except for the building savings contract and the pension insurance, which we only want to suspend in the building case. Or would the bank only consider 5,000 euros from the building saver as equity, which would not really change much.
