The local management is all human though. Communicate, communicate and communicate. If it does not get anywhere, try to sub lease to someone else. Your monthly rent is 10500/15 = 700. If you are willing to lower it to 600, may be someone will want to rent from you. You will come up with the difference, which is $1500. That is s lot cheaper than court costs.
Or you can offer a lump sum to get out of the lease. At certain dollar amount, they will take it.
