With a bank? And from that you conclude that EVERYONE advises like that?
Of course, you can waste your time looking for the unicorn. Or use modern, fast methods and just get the stuff done, often at top conditions.
For our financing, I was very active and also focused on Volksbanken and Sparkassen. One Volksbank even got back to me, I went there, two hours of talking. It was nice, but no offer because financing over 300k (lol) and they then calculate a safety discount of 30% if it goes over that. I had 20% equity in my pocket, so that wasn’t enough, they wanted me to include a useless and expensive KFW tranche. No, thank you. I also had two Sparkassen. First lesson: Both only finance in their "territory". Figuring out which one in my case (confusion between current residence and construction site) already took two weeks. When that was settled, the appointment (also on site, how annoying!) didn’t happen. Advisor was sick or something else. I didn’t ask anymore after that.
They are just doing themselves out of business. I need banking, but not a bank.
