25K Will get you a pretty cool spot in Disco Bay - 3 Bedroom/1000Sqft probably even with a balcony or small garden if you search a bit.
Out in south Lantau even better.
Midlevels - 800-950 sqft apartment(2-3 Small bedrooms). The older the building the bigger the size you will get.
aprox 25K is what CX So's start on for the first 2 years...
