An inventory is necessary whenever a property is let out to tenants for the first time or when the property is let to different tenants. It is extremely important as it will reduce the risk of any dispute about damages to the property or the contents between the landlord and the tenant at the end of the tenancy. The inventory should be recorded when the property is in the state at which the tenant is able to move in.
The check in is a protection for the landlord and the tenant as it is clear to all parties that the tenant has been given the opportunity to accept or amend the inventory and has confirmed a valid snapshot of the property and condition of cleanliness at the beginning of the tenancy. It is also a reassurance for the tenant that they will not be held responsible for faults with the property that have already been identified and agreed at the check in.
