I only said that personally it would bother me. If, after such a long repayment period, you still have an outstanding debt, you have to be aware that you have already paid the bank a lot of interest. After 18 years, we will have paid approximately 30,000 euros in interest and the house is completely paid off. In this case, the builders would have paid 115,000 euros in interest for a house the same size as ours and still have 90,000 euros left to pay with an uncertain interest rate. The bank will be happy, but for me it would be way too expensive and uncertain... even if I consider that I only took out a 220,000 euro loan for the 30,000 euros interest, I see the 320,000 euros with 115,000 euros interest and 90,000 euros outstanding debt as a clear disproportion. In other words, I will have paid about 380,000 euros for my 151 sqm house including bank interest, and Hinterlandbau, for a house of the same size and without having to pay for the land, would already pay 435,000 euros + at least 90,000 euros + x, so probably well over 500,000 euros for a comparable property and without land! So for me, that would be way too expensive, lovely as it might be... or if I have a calculation or logical error, then please enlighten me.
