HK is where you will be living for the next 10 years or so, so make sure you know what you are getting into. No airline (or very few) will consider S/O time....so you will be in HK for a long time, paying your OWN rent. A lot can change in 10 years, you may want a family, bigger living space etc, etc.
Make your decision with your eyes WIDE open, consider every possibility before you sign on the dotted line.
HK rentals:
Hong Kong property & real estate - find Hong Kong apartments, flats, accommodation- Square-Foot
Its your decision, but you can't say you haven't been warned.
