Hello and thank you for the opportunity to assist you. My name is ***** ***** I will do my very best to answer your legal questions.
Q: Do I have to pay these costs?
A: You wouldn't have to pay for normal wear and tear on the carpet, nor would you have to pay for mini-blinds in perfect condition. You may have to pay for a crack in a back window that occurred while you were in possession of the apartment, however, even if you weren't aware of the crack. Also, you would have to pay a cleaning fee if the refrigerator and oven were not properly cleaned. If the counters were properly cleaned, then you would not have to pay for that.
Q: What is normal wear and tear on carpet? What is the industry standard cleaning fee for an apt and the life of carpet? Also they say I have to pay for a full paint out on the entire apt. There were 6 nail holes in the dining/living room and a mark by the front door.
A: You'd have to ask a carpet expert and probably a maid service to find out the industry standards for those costs in the city you lived at in Oklahoma. It would obviously vary by location. As for the paint job, you may have to pay for repairing the holes and the mark, but probably not paint for the entire apartment.
Here's what you can do: If the landlord won't give you back your entire security deposit (less the amount that you believe is fair), then you can sue him in small claims court. Or, if there is no deposit, and you won't pay the bill, then the landlord can sue you in small claims court. But the bot***** *****ne is that once you get to court, the landlord will have to prove that you caused more than ordinary wear and tear, and that you left the kitchen a mess. You and your mother can then dispute that, and the judge will ultimately rule in favor of who he believes. But if it comes down to your word against the landlord's word, and the judge thinks that you both are sufficiently believable (i.e., the evidence doesn't swing towards one of you), then you should win because the burden of proof is on the landlord to prove the damages that you caused.
Does that answer your question? Please let me know if you need clarification, as I am happy to continue helping you until you are satisfied.
