For most of Australian history, the answer was a flat no: a woman often could not get a mortgage at all without a man to sign for her. That the question is even askable today is recent. The barriers that remain are real, but they are different from the ones the history built.
It is one of the most searched property questions in the country, and the search itself carries a small ache: the sense that buying a home alone is something you have to check permission for. So let us separate two things that often get tangled: what the history did, and what the picture looks like now. Neither is a verdict on you.
The history: why this was ever a question
Not long ago, a single woman buying property in Australia faced a wall that had nothing to do with her income and everything to do with her sex. Banks could, and did, refuse women loans or accounts, or require a husband or father to guarantee them. It was not until the Sex Discrimination Act 1984 that financial institutions were formally prohibited from refusing a loan or account on the basis of sex or marital status.
Read that date again. 1984. Within the working memory of many women's mothers, a woman's ability to borrow depended on a man's signature. The idea that property is naturally a partnered pursuit, or a man's domain, is not ancient. It is the cultural residue of a lending system that was closed to women by law until recently. If buying alone feels like swimming against a current, that is partly because, for generations, there was one.
The numbers now
The current picture is more equal than the history, and still not equal. According to Cotality's (formerly CoreLogic) Women and Property 2025 research, women's overall dwelling ownership rate sits at around 62.7%, slightly below men's 64.4%. The gap widens for investment property: around 11.4% of women own at least one residential investment property, compared with 14.2% of men, and the gap is starker among younger Australians.
So single women do buy homes, in large and growing numbers. The barriers that remain are mostly economic rather than legal, and they trace back to threads covered elsewhere in these notes: the gender pay gap means a lower income to borrow against, and the motherhood penalty and career breaks can interrupt both savings and borrowing capacity. One income is one income, and the system that sets what that income is was not built in women's favour.
The concepts worth understanding
If home ownership is something you are exploring, these are the general terms that shape the conversation. Understanding them is not the same as being told what you can afford, which only a lender or broker assessing your full situation can determine.
- Deposit. The upfront portion of the purchase price you provide yourself, with the rest borrowed. A larger deposit generally means borrowing less and may affect the cost of the loan.
- Borrowing capacity. A lender's assessment of how much it may lend you, based on income, expenses, existing debts and other factors. It varies by lender and changes with interest rates.
- Loan-to-value ratio (LVR). The size of the loan compared with the value of the property, expressed as a percentage. It is one of the levers lenders use to assess risk.
- Lenders Mortgage Insurance (LMI). An insurance premium a borrower may be charged when the deposit is below a certain threshold. It protects the lender, not you, and it adds to the cost, so it is worth understanding early.
- Government schemes. At various times, federal and state governments run programs intended to help buyers, for example schemes aimed at lower deposits, or concessions for first-home buyers. Names, eligibility and thresholds change often, so any current program should be checked at the source before relying on it.
None of these tells you whether buying is right for you. They are the vocabulary that lets you have the conversation without feeling lost in it.
The short version
- Until the Sex Discrimination Act 1984, a woman could be legally refused a loan on the basis of her sex or marital status. Borrowing alone is a recent right.
- Women's dwelling ownership (around 62.7%) sits just below men's (around 64.4%); the gap is wider for investment property (Cotality, 2025).
- The remaining barriers are mostly economic, not legal, and trace back to the pay gap and career breaks.
- Deposit, borrowing capacity, LVR and LMI are the core concepts worth decoding before any conversation with a lender.
- What you can afford is specific to you. A licensed broker or adviser assesses that, not an article.
This is context, not a green light or a red one. Whether buying alone is possible or wise for you depends on numbers specific to your life, and no article can run that calculation. What you can take is the vocabulary and the history, so the next conversation is a fairer fight. If you are exploring it seriously, the people who can assess your situation are a licensed mortgage broker, a financial adviser, or, if money is tight, a free financial counsellor (the National Debt Helpline runs a free service).
The law stopped asking for a man's signature in 1984. The economy did not get the memo all at once. Buying alone on one income is harder for women, not because the door is locked anymore, but because the income the door is measured against was set by a system with a long head start on paying men more. Understand the system. Then decide.
