Strange landlord behavior?

[Account Closed]

So I'm a buy-and-hold investor and have some experience as a landlord. I also happen to be a renter and I'm trying to figure out some strange landlord behavior. I thought this would be a good a place as any to gain some insight.

About a month ago, I got the news that I'm being transferred from New York to a new job in Europe and I'll be relocating in October 2015. Since my current lease ends in February 2016, I immediately called my landlord to let them know and to find out what the next steps would be. The lady at the property management company was quite pleasant and let me know, that in accordance with my lease provisions, I would be responsible for finding a replacement tenant. She said she would discuss this with her manager and get back to me with the new rental amount.

I waited several days to hear back from her. Nothing. So I sent a certified letter basically repeating what I had already told her over the phone and asked to hear back. Nothing. In order to find a tenant, I need to know what the rental requirements are and the rental amount. Besides my certified letter, I've called, left messages, sent emails, etc.

What do I do here? I only have a month left in the USA. At which point I will leave on a one-way ticket to Europe. Should I just assume they are allowing me to break my lease and that they don't need me to find a tenant?
