Yes, the world does contain a housing market that is less sane than the one in Sydney.

So, if you want to make money in the Hong Kong property market, you can simply follow these easy steps:

1 Buy a flat that doesn't yet exist.
2 Wait until it does.
3 Sell it immediately.

What? There's a problem with this plan? Oh, yes - someplace to actually live. You can't rent, of course, because that would eat up your profits. Fortunately, Hong Kong is liberally blessed with flyovers, so I'll see you in one of those cozy nooks beneath them!
