You need to pay a deposit. If it’s easier for you, you can pay the deposit in installments, in a monthly amount equal to the amount of the rent. This means that you will pay the deposit in two or three installments. We are talking about agencies, and for private accommodation, it goes as the boss says. There is a possibility, if you are taking over the apartment, and it has not been renovated, to renovate it at your expense, and in return you will be denied the payment of the deposit.
