When do I have to pay the fixed service fee to Wunderflats?

We will issue you as the lessor a one-off invoice for the entire rental period after the rental agreement or the extension of a rental agreement has been signed. If the rental agreement is signed more than 60 days before the tenants move in, the service fee must be paid to Wunderflats no later than 45 days before the tenants move in. If the rental agreement is signed less than 60 days before the tenants move in, the service fee is due within 14 days after receiving the invoice.
