Photograph literally everything, including things that seem irrelevant at the time — light switches, small wall marks. Has genuinely saved me twice now.
A friend just lost most of a hefty deposit over 'damage' that was there when they moved in and couldn't prove otherwise. It's made me paranoid about my own move-in. For those who've been through a move-out here — what should I be photographing, dating, and getting in writing now, so I'm not fighting for my money back later?
