Hello everyone,
First of all, I (thread starter) have to briefly mention that I had to change my username because it did not comply with the forum rules. Sorry about that. I was not aware. Thank you very much for the feedback and opinions. So, we will definitely remain childless biological violence. If I look at our income in relation to the rate, additional costs, and maintenance reserves, I think it should also work. This is also with regard to the current warm rent plus savings plan. It is quite an important life decision. I rather have the small "problem" of having to borrow 450k. But apparently this is "normal" for such projects. As I said, even if there are concerns/suggestions regarding the salary, just let me know. I / we are happy and grateful for every opinion.
Best regards Phil
