I mean, really, you can lose money from your deposit which afaik is supposed to cover damage because your extractor fan isn't taken apart and cleaned or the inside of the kitchen cupboards aren't pristine? Since when was that damage?
Seems like landlords aren't happy enough getting tenants to bankroll their lifestyle - they want tenants to prepare the property for the next person too which is surely the landlord's job.
People who own houses and sell them don't have to do this on pain of losing several hundred pounds. It's just a rip off.
