It is important that you create an inventory at the start of each new tenancy and get this agreed, and signed, by the tenant. Ideally you should go through the inventory together at the sign in and leave a copy with the tenant for 7 days to record any snapping points not identified immediately. Without a signed inventory you will find it very hard to keep part or all or a deposit for damages.
At the end of the tenancy you should use the start of tenancy agreement as a guide for your pre end of tenancy inspection.
During the tenancy you should carry out regular property visits and advised the tenants of any concerns that you would like to see addressing before they become too challenging.
