You can receive your deposit back after:

• Rent amounts according to the tenancy agreement has been paid
• Bills(utilities) for the property have been paid, delivered and calculated
• The tenancy has ended according to the end rental dates
• The check-out inspection has been completed
• All rent, utilities and other agreed charges have been paid.

The landlord checks the condition of the property and reports to the tenants and sometimes the agency. If there is no damage and no unpaid amounts, the full deposit is returned to you. 

If there is damage or unpaid amounts, the corresponding costs may be deducted from the deposit, and the remaining balance (if any) is returned to you.

In some cases, and only if you and the landlord/agency agree, the final utilities for the last month can be deducted from the deposit instead of being paid separately. This must be clearly agreed in advance.
