FYI: THIS IS SUPER ILLEGAL

A landlord MAY NOT keep your deposit over ‘normal wear and tear’. They may ONLY collect on something that is YOUR FAULT. They cannot charge for carpet wearing down or needing a new coat of paint after a few years, or the furnace needing a replacement because it’s old. They can charge you for punching a hole in the wall that you never fix, or spilling paint on the carpet requiring a specialized cleaning or replacement. And they may ONLY keep what covers the repairs (If insufficient, then and only then may they keep the whole deposit, as in your deposit did not cover the damage you caused). 

KNOW YOUR RIGHTS AS A TENANT. You landlord MUST return your deposit unless it was damage you directly caused, and ONLY the amount needed to fix the damage, and not one penny more. 

Join a tenants' union.
