When renting a house, you can hire an agent to help you search. Be aware that it will come with some charges. When you find a house yourself, the agent hired by the landlord to rent the house is not supposed to ask for commission from you because their contract is between them and the landlord, not you because you didn’t hire them. So be careful of that and if it has already happened to you, be sure to ask for your money back and/or engage a lawyer on hourly basis to write them a letter to return your money. You can also get legal insurance to help with stuff like this. The monthly costs for legal insurance are very affordable and you mostly will get your money upfront. ABN AMRO offers legal insurance but you can also check Independer.nl for other options
