For the information of the OP, your housing budget alone is significantly higher than what most new grads in HK earn. Starting salaries can be as low as 9k a month; 12-15k is considered reasonably good. We start our new grads on a little more than that, because we import them from overseas - but still under 20k. You're very lucky - you don't appear to realise that. But if you want to socialise with young people from HK, you may be out of luck. Still, plenty of youngish expats in HK - try meetup.com when you arrive for meeting folks other than those in your office.
