China has a big housing problem because buyer made full payment before the houses are built. This give developers a chance to amass all the money and never built the house. In SIngapore, developer can only collect full payment when the houses are fully built. They can only collect a 5% deposit when laying the ground work and must sell all the houses within 5 years after built. So only those developers have huge finance are able to built houses. This give Evergrand the chance to collect huge money but not even lay a single brick. That why no China Developer dare to come to Singapore to built house.
