In Cambridge 1 in 20 new-build properties is purchased by non-resident Chinese buyers, which has been one of the contributing factors that has seen prices rise by 50% since 2010 [1] and are 47% above 2007 pre-GFC peak [2]. Note - unlike Vancouver that has a a big (30%) local Chinese population, only about 1.4% of the Cambridge population is Chinese or of Chinese ethnic origin [3]
To some extent this is just about free markets and a movement of capital. But it is starting to price out many local people out of the property market that does have a social impact.
There are other factors at play including a booming tech & biotech sectors, restrictive planning, stock-piling of building plots etc, but the foreign buyers issue is a major contributor.
