On move-in day, our clerk attends the property with the inventory report, they check it page by page and add any extra notes in case things have changed since the inventory was made. The tenant is also present so they can check the property and raise any questions they may have. The idea is that agreement is reached as to the condition of the property; this is documented and signed off by the tenant.
A document is signed by the tenant confirming key receipt, cleaning level, smoke and carbon alarm tests and general condition of the property to avoid any disputes at check out. A full report is provided to all parties to back up the check in findings.
