Advice needed - defaulting tenant

Hi, my tenant signed upto a fixed term lease which expires in August 2015. However, I have credible information that he is planning to leave HK (company transfer) by end January 2015. He is already late with the rental payment for November and I suspect that he is not planning to pay any more rentals.

My potential loss is:
1. unexpired period (approx 6 months) of fixed term lease;
2. if he leaves in January, that will amount to 3 months unpaid rental (I hold 2 months deposit).

Anybody have this experience previously? Do I need to get a lawyer? What are my options here? I'm nervous that if he really defaults and leaves HK it will take me a while to get possession of my flat.
Any recommendations for a good and cheap lawyer (HK island).

Any input welcome. Many thanks indeed.

1) not necessary spend money on lawyer at this stage
2) talk to your tenant direct & open, most likely he expected the 2 months deposit to cover rental of Nov & Dec.
3) contact your property agency to post the flat for rent
hope it helps
