Bless them, some haven’t discovered the joy of vacuuming or cleaning in general. So occasionally it can be a challenge when it comes to helping them get their deposit back..and as end of tenancy inspections seemingly becoming far more strict I am always trying to tell them what to expect. So always take photos of your house especially if there is damp, damage, stains on the carpet when you first move in. Print them off and stick them in a folder. If you spill anything take action immediately or as soon as possible. Google and You Tube will help.
