The overall associated notary fee is typically 1,5-2 % of the purchasing price. The cost is lower, the higher the purchase price is, and the higher the mortgage amount. To be more precise:
The fee for the purchase is about 1,1 % for a house of 200.000 Euro and declines to about 0,9 % for a house of 1 million Euro.
The fee for the mortgage passing and registration is about 0,6 % for a mortgage of 200.000 Euro and declines to about 0,5 % for one of 1 million Euro.
Adding a second mortgage component (eg a KFW loan of 50.000 Euro) will add about 200 Euros to the cost.
Among other things, the notary will take care of drafting the purchasing contract, entering the buyer in the land registration, and generally taking care of all communication with the German tax office. Keep in mind that a notary will charge you for just drafting the purchase contract, even if you don't end up buying the property.
This fee estimate includes the cost of registration in the land registry.
