I would think about the following issues before buying under my children's names:
1. Should I burden them with a huge loan at such a young age? I would prefer they buy something that they can truly afford. But, I can help with some initial payments. Maybe buy BTO first. It is a citizen's privilege.
2. There was a story of a 87 yo man suing his wife for a house bought in her name.

3. The children may fight over the property. Sometimes, it may not be your children, but their spouse and their spouse family. Even if you have willed the house (which I am not sure is possible since it is in their names), there is nothing to stop them from fighting over it since it was bought with your money, which they will contest for their rights as your biological children.
4. For some reason or other, if any of the children divorce, you must be prepared to lose 50% of the house to his/her spouse.
