Ive lived in my apartment for two years and my lanlord wants to charge me for normal wear and tare to paint walls and replace carpet. I have a non refundable pet deposit and they want to keep my security deposit. They said my pet and children are the reasons to replace the carpet and paint the walls. Isn't that the reason for a non refundable pet deposit? Don't they have to paint walls before a new tenant moves in? There aren't any holes in the wall nor did I paint the walls different colors, they are still white.
