We just signed a 2y lease for a 830sqft apartment. 3 beds 2 baths. Not near Central though but because we wanted to be away from the buzz. Commute door to door is 30 minutes.
Rent is 37k HKD
It really depends on location, size and the condition of the apartment. We could have lived relatively cheaper had we wanted a house that hasn't been renovated recently.
my advise: do the legwork and pass by multiple agents in the area u would like to live. They will ask you to sign a form but you are not obligated to sign anything
