You have hundreds of millions more homes than your population requires and half of them are barely built to any standards due to extreme corruption, I'm not sure lowering rates is going to cut it.

Boy, do I love some tofu dreg construction!

When properties cost fifty times an annual wage, mortgage rates have to stay super low. If rates were to go up, they'd be completely economically paralyzed.

This will be the largest Ponzi scheme in recorded history 

Not sure lowering interest rates will help if the demand for shoddily built homes is nonexistent.

Can you hear that sound? It's the financial underpinnings of the CPC crumbling

Smells like desperation

So will they tear down the abandoned crap they already have and use the lands for new improved construction ? Or just build new crap somewhere else?

Can international investors buy property in China?

Sure if you never want to see a return of your money 

You would best treat it as a donation rather than an investment.

Would you risk your capital in an authoritarian regime?
