You should mark your property as leased once you have accepted a tenant for the property. Generally, this will be when the tenant has paid their bond/rent in advance and signed the tenancy agreement however you can mark as leased earlier if you would like.
Stressed about the tenant backing out but don't want to keep advertising while you wait? We have a free 30-day rental relisting guarantee. This means that if the tenancy falls through after you've marked your property as leased, you can contact us anytime within 30 days and we will reinstate your property listing completely free of charge.
