As reported by Business Insider:

One red flag is the vast number of vacant homes spread through China, by some estimates up to 64 million vacant homes.

We’ve tracked down satellite photos of these unnerving places, based on a report from Forensic Asia Limited. They call it a clear sign of a bubble: “There’s city after city full of empty streets and vast government buildings, some in the most inhospitable locations. It is the modern equivalent of building pyramids. With 20 new cities being built every year, we hope to be able to expand our list going forward.”

Recent statistics show that there are about 64 million apartments and houses that have remained empty during the past six months, according to Chinese media reports. On the assumption that each flat serves as a home to a typical Chinese family of three (parents and one child), the vacant properties could accommodate 200 million people, which account for more than 15% of the country’s 1.3 billion population. But instead, they remain empty. This is in part because many Chinese believe that a home is not a real home unless you own the flat.

And so people prefer buying to renting, and as a result, the rental yield is relatively low.

Many many more photos at the source.
