What does 'kosten koper' or 'k.k.' mean and does this include our real estate commission?

The kosten koper or costs for buyer include the transfer tax and notary expenses, which include drawing up the deed of delivery and registering it in the Land Registry. In addition to the aforementioned costs, there may be notary fees for the preparation and registration of the mortgage deed. Commissions for estate agents, mortgages fees and possible costs for a valuation report or technical survey are also not included. These costs are generally settled through the final bill drawn up by the civil-law notary.
