Subleasing nightmare?!!?

I recently purcahsed a home, I was set to close on it 2 months before my lease was up. I posted an ad for a subletter and decided on a young family and contacted the office and had the couple do so as well. They filled out an application and were approved a set to move. I move out clean everything, pay for new carpet and repaint the walls so it is like new for the people when they move in the next day. The next day I find out from my apartment management that the couple decided not to move in, I discuss with the manager what I can do and I am told that I will be reponsible for the remainder of my rent until they can find a new tenate. 2 weeks later I get a letter in the mail saying I owe the apartment 3000.00 total 1600.00 for the remaining rent until my lease expires in August and 1400.00 in misc and subletting fees and if this amount is not paid in full in 2 business days they will turn me over to collections. What can I do to protect myself?

I think you're screwed.

You could have a legal case, against the couple who signed the papers to sub-let. See a lawyer.

great fix you have got into. might as will stay until the lease runs out and pay regularly as per agreement

You can give your rental company a written 30 day notice to quit. If in those 30 days, they find a renter, (which, if they know what the hell they're doing, they will!) you will only be responsible for 1 months rent.
