Is Germany more like the US? In the Netherlands, before 2020, the cost of getting the loan was negligible. For a while earlier, it was zero - all transaction and notary costs could be included in the mortage. You could literally buy a house with €0 in your bank account, as long as you had the necessary income.

These days it's not so easy, prices have risen by 50%+, but you still pay less on a mortage than the equivalent rent, by a large margin. Renting (if you can buy) is pretty much throwing your money away.
