The Importance of Check-In and Check-Out Reports One of the most important things that you need to do as a landlord – among the many – is to carry out an inventory. This means making a list of everything in the property that you are going to rent out, including the structure of the property itself - walls, floors, ceilings, roof, drainpipes, drains, and so on. Now this is not just a list of items but covers the condition of every item as well. This is important both for you as a landlord and for your tenant as well. If you have something that is in perfect condition when you let the property, but the tenant then somehow damages it during the course of the tenancy, then you are entitled by law to deduct money from the tenant’s deposit in order to cover any repair or replacement.
