foreign property ownership

[Crowflies]

I have a son who lives in China, he has no tax ties to the UK an employee of a Chinese company (EU parented).

Can I gift him 150k to buy a UK property and he can let that property ? The income for this would be below the personal tax threshold (around 7k per annum). What tax would he or I be exposed to by doing this? property based or otherwise? I understand as a result he may need to pay more of his student loan as a result of the income in the UK, he already pays some based on his Chinese income.

I currently have my own primary property, he has none in the UK.
