I'd guess they're good enough at this game that they're even more leveraged than the 20% conventional downpayment requirement and probably using the (bubble inflated) equity to print new money out of thin air and get another property.
I have no idea what's actually going on but this is how I've seen people speculate on real estate in other markets and seems like the obvious thing to do. I would even guess that there are ways of borrowing against money that is still in China, which subverts their restrictions on moving money.
I also predict that this hiccup will be invisible within 6 months, for two reasons.
1. Nobody goes shopping for houses in December and January because it's cold and there is Christmas/Lunar New Year etc, especially with the storms this year.
2. These restrictions are going to have loopholes and a market this big has an implicit bounty on finding them. They'll figure out how to get Canadians to hold the title to dodge the 15% foreign tax and they'll sign rental agreements with their lawyers kids/pets and say it's officialy rented or whatever else they need to do.
They might live there, or have a family member/student live there, or their wife/kids while they stay in China.
These people might be a little 'price inelastic' but also 'not stupid'. A 15% advantage for local buyers gives some leverage.
It could also just be a little skittishness - 'what will the tax be next year'? Or 'will this cause other buyers to be skittish because if that happens, prices will drop, so I'll hold off'.
15% will definitely pull out a chunk of buyers - that pull out might be enough to make those buying 'at any price' not enough to keep the bubble up.
Finally - Toronto saw a big increase after Van put in the law. The money just may have switched gears into TO.
If the intent is to just park money then a 15% cost to do so might or might not make sense.
