TFW are used to drive down wages. international students do purchase houses for their families out of country - it happens more in some areas than others. And if someone couldn't get in as a student, they might try to get in as a TFW and spend their family money on a home - I don't know how often it happens but its allowed because TFWs DO buy houses.
