That's the thing, though, I kinda don't believe it. I mean, sure, people from China buying US real estate; I can totally believe that one (and that would increase demand and thus put upwards pressure on sale prices)
The part I have a hard time swallowing is the idea that they'd let them sit empty. The real estate agent they bought from would be super happy to hook them up with a full service property mangement company that could deal with renting the things out; I'm sure said agent could (for a hefty cut, of course) set it up so the owner need not be bothered at all.
I mean... I guess there could be something I'm missing, but the idea of people buying up some of the most valuable realestate in the world and then letting it sit empty (and supposedly paying somene to come by and check on it, etc...) just seems really unlikely vs. buying and renting it out.
To rent out your Ferrari you'd have to run an agency and couldn't use it as you wanted to. Which kind of defeats the purpose of a luxury good.
(It's hard to find data on how prevalent this is... From one article, it looks like a Palo Alto realtor estimated in 2015 that about 20% of home sales were to Chinese investors, with about half of these leaving the house unoccupied: http://sanfrancisco.cbslocal.com/2015/04/28/realtors-printin... )
But yeah, I haven't done the digging to attempt to quantify that effect.
My second point remains, however. Building more housing does not inflate prices. (and yes, I know it's not quite as simple as econ 101 supply and demand, but)
Apparently they'd keep enough of these units off that they could keep the 1 bedroom price around $2k, but not too many so the city wouldn't catch on.
I couldn't find anything else though, either in the news or other people in knew in real estate, to corroborate that; so maybe he was blowing smoke or taking tokes.
