You will receive an inventory report within 48 hours of moving into the property. You must go through the report thoroughly before signing it off as this will be used at the end of the tenancy to check that no damage has been caused. If you do not let the agent know of something damaged in the property that was not on the inventory, you could be liable at the end of the tenancy to repair such item.
It is normal to give a tenant 7 working days to complete their checks and sign off the inventory. If nothing is completed or sent to the agent with 7 working days of receiving the document, it will be given that you agree to the content with no changes needed.
