25k will get you 90m2 appartment in a high rise block. Fine if you are single if you have a family , you will be single very shortly after moving in to a place like that. A low rise place 130 -150m2 will set you back 40-50k for a garen unit and 30-40 for a higher block...then at least you will not have to give your ex a house.
let me know if you need more info about living in Hong Kong
