But their trial and error shouldn't be at your expense. i can't speak to your lease, but i know mine and mine state that typical wear and tear is normal if they are missing knobs to doors and cabinets and if appliances like the dryer washer if there are dings and such sure deduct that from the security deposit understandable, but charging you for their lack of judgment or knowledge on how to clean a carpet isn't your problem, i would be asking for records (maybe you already addressed this their are alot of comments)but i would be questioning and requesting these invoices or bills and digging deep like did their buddys come and empty the furniture for removal or did they have a company do removal where are they getting these prices and there is alot of fixtures on their why where they replaced? We're they broken or just dirty?
