However, the rules for buying these two types of properties are different:
1) There is no restriction for international students to buy a new house. The Australian government has been encouraging foreigners to invest in Australia, but only in new houses. The new house purchased by international students can not only live by themselves, but also be subletted to other students. Even if you leave the country later, you don't have to force the sale.
2) International students can only buy a second-hand house for their own occupation, not as an investment. If the visa expires, you must sell the property one month before leaving the country. In NSW and Victoria, there is a price limit for buying second-hand properties where international students live. Foreign students need to apply for FIRB documents to purchase second-hand houses, stating the purpose of residence. Whether the government approves or not is uncertain (depending on the measures you fill in the form and the approver).
It should be noted that it is basically impossible for international students to borrow money to buy a house in Australia. Unless you can prove that you have a fixed income during the work period stipulated in the visa, in addition to supporting your consumption, there is still a surplus for repayment. If you need a loan, you can write your parents' names. (It is best to consult a loan intermediary, and some intermediaries can make loan suggestions according to specific circumstances. )
Warm reminder: If you plan to stay in Australia for a long time in the future, it is best not to write your own name when buying a house, but to write your parents' names, because you can also apply for the government's first home purchase subsidy after getting a green card.
