Make sure that the owner or agent is present during the inspection, this is important. Budget about 90-120 minutes for this. Make sure that everything, and I mean everything is recorded, both on camera as well as on the fault list. Do a thorough inspection, by thorough I mean opening and closing every last tap and cupboard door and record the result. Photograph things like on top of cupboards and burglar bars, then run a finger across it, and photograph the finger and then the cupboard shelf / burglar bar again. Check every plug socket with a load drawing appliance, like floor polisher. photograph every light switch. Turn all the stove plates and oven on high simultaneously and leave on for at least 10 minutes. Check that every door, including cupboard doors and drawers open & close properly. Where something cannot be checked because of its state (too filthy or broken, or inaccessible), make sure it is recorded.
This serves two purposes: 1) a record of the condition -- the RHT may need it to determine whether the unit was tenantable or not; and 2) when they move out, they will be blamed for everything.
