Almost all landlords require a security deposit. The deposit is a guarantee for the landlord in the event that the property is left damaged or if the tenant is in arrears with rent payments.
Make sure you keep a copy of your ‘check-in report’ and/or supporting photos as proof of the condition of the house when you moved in. You don’t want to be held responsible for damages you didn’t cause.
Within a certain period, stipulated in your rental agreement, a settlement of the deposit is made. Make sure your new address and bank account are known to the landlord.
