The problem is the ridiculous jobsworths that are inventory clerks
Scribblegirl I think that is unfair tbh, it's a tough job to be an inventory clerk and it generally ( or should say at check in) to make sure things are put in their original rooms
the amount of detail and things a clerk has to check is mindblowing, and thankfully the photo evidence prevented you from being charged, yes they should have double checked etc.
The job of an inventory clerk at check in is to make sure that YOU are not taking on a responsibility for an existing issue/damage/defect
At check OUT it's to make sure that the LL doesn't get saddled with dealing with damage/defect that YOU have caused, with allowances for fair wear and tear.
If a property has been cleaned professionally, the clerk will know, and the tenant can ask for copies of receipts to prove that the property was cleaned specifically for the beginning of the tenancy. If it is proven that there has been subsequent access to LL or builders or any third party before you have taken possession, it may be possible for the tenant to prove that the check in was compromised, Or certainly they can insist on the condition update is added to the report. Likewise check out, if the property was cleaned but a builder or LL/agent entered the property before check out
The main issue with tenancies is usually the LL or letting agent are considering the deposit as theirs and they are trying to hang onto as much as possible of it.
the deposit belongs to the tenant. full stop, if a LL/Agent wants to keep any of it, they have to prove it.
If a property has been cleaned professionally, the tenant is frankly foolish to return it in any other condition than professionally cleaned WITH RECEIPTS.
