It may be possible for you to purchase property with your partner, even though you are not yet married.
It all depends on their current visa status. If they are on a Prospective Marriage Visa (subclass 300) and are being sponsored by you (an Australian permanent resident or Australian citizen), it may be possible to buy a home together.
However, if you are not yet on a partner visa, then it may be best to buy solely in your own name. Please call our mortgage brokers on 1300 889 743 or enquire online and we will let you know if your fiancé is eligible.
