The financial consequences of being single/divorced in China make it easier to buy a second property. Reports suggest this is increasing divorce rates in China, despite couples remaining "happily married".
A loophole I am sure the government will want to find a way to close!
Home purchasing rules in China treat married couples as a single unit. At present, a first-time buyer and resident of Shanghai can buy one property with a 30% deposit and 10% discounted interest rate. A married couple can buy up to two properties. The deposit for the second property has to be between 50% and 70%.
