7M HKD for a condo in BKK is way overpriced
You get very good flats (in great areas) i BKK for about 3/4M HKD
Obviously, if living environment, space or quality is the only concern, there will be plenty of other locales which is much better in the "value-for-money" department than HK.
But of course, choosing where to live isn't really only an issue of living environment/space/quality, otherwise none of us would be in HK, now would we?
Australia, great place. Go there.
