I rented in NC and failed my move out inspection due to mismatched paint and it wasn't clean enough. The inspector said they would deduct from our security deposit for the cleaning and paint. Its been three weeks since I've moved out. They are still not finished with the house, still charging me rent, and told me to keep the utilities on until I've "passed" inspection. Also said they would take oust another 75 dollars to inspect it for the last time. Is this protocol?
