Previous comments on rental costs seem way off. There seem to be plenty of places available for $6000-7000 PCM.

HK is a crowded place and you can't realistically expect to be living in the centre of town on a SO paycheck can you?
ummm...... why would you not expect to live in town? This is life, and for an expat - this life sucks unless you live in a half way decent place. Why give your life to Cathay for the measly salary they are going to give you. You are not going to get to fly airplanes either. So, basically, you are selling your soul for nothing. 6000 gets you a shared room with a helper maybe, but that is it. You can live in a cardboard box on the beach. You can live in 400 sq feet 2 hours from the airport, or you can maybe get a hole in the wall with a lot of noise, in a bad area of town.
