Sometimes landlords do over claim for damage, and without valid reason, thats why there is a deposit scheme in place
From experience of student lets,
fire alarm control box smashed off wall,due to key to cancel it going missing,
stair spindles smashed out of staircase,and use for play sword fighting,
fridge door wrenched off after being left open and frosted up and wouldnt shut, they didnt defrost the thing first,
Bedroom painted black and purple,
Bed soiled with blood and other body fluids,
new double glazed windows forced beyond their restrictors, damaging them irepairably,
bin bags been thrown out of upstairs windows in to rear garden,
Light fitting smashed with footballs after games of indoor football,
scores given to male partners written on floor under bed, after carpet was removed due to soiling,by a female student,
Doors wrenched off hinges as a joke on fellow tenants,
not all students are innocent little educated geeks at all times.
