The times when you could finance 300k with an installment of 1200 euros are over.
Ups, I have to tell my colleagues in the retail customer sector that the business they are doing is actually no longer possible... Joking aside. The current conditions for the mentioned ratios are just under 3%. With a repayment rate of 1.5%, you end up at around 1,250-1,260€/month. (With 1% repayment, the condition does not change, but the installment falls below 1,200€/month.) As you can see, financing is currently well possible within this range. If you want to repay quickly, of course it costs more. But that is not necessarily required.
