Single parents can buy an investment property, but the loan has to work on one income and still leave room for your family. This article covers how lenders assess you and which loan choices matter most. It also covers the risks to weigh up before you commit.
You carry the household on your own, so the question is not just whether you can borrow. It is whether you can hold the property comfortably if rent stops or costs rise.
How Do Lenders Assess an Investment Loan Application for a Single Parent?
Lenders assess whether your income can cover all your debts and living costs, including a buffer for higher rates. Banks regulated by APRA must test new borrowers at a rate at least 3.0 percentage points above the loan rate.
That means a repayment you can afford today is tested against a much higher one. Your living expenses, dependants and existing debts all count. Even unused credit card limits can reduce what you can borrow, because lenders may apply a notional repayment based on the limit. Closing cards you do not need before you apply can help.
If you are unsure where you stand, our borrowing capacity page is a good starting point. A broker can also compare lenders, since each one sets its own policies.
How Much Rental Income Will a Lender Count?
Lenders generally count no more than 80 per cent of expected rent. APRA's view is that prudent policies should allow a haircut of at least 20 per cent for periods when the property is empty.
The haircut covers vacancy only. It does not cover management fees, repairs or other holding costs, so you need to budget for those yourself. Lenders also tend to rely less on a rental appraisal than on rent actually received from a tenant.
As an illustration, if a property is expected to rent for $500 a week, a lender might count about $400 a week. The other $100 is your safety margin, and real costs sit on top of that.
Interest Only or Principal and Interest: Which Suits a Single Parent?
Interest only keeps repayments lower for a set period, but you do not reduce the loan. Principal and interest repayments cost more each month, but they pay down the balance.
Interest only does not lift your borrowing power. Lenders assess it as if you will repay principal and interest over the remaining term after the interest-only period ends. A 30-year loan with five years interest only is tested over the last 25 years.
Here is an illustrative example at 6.75% p.a. on a $500,000 loan. Interest only costs about $2,813 a month ($500,000 x 6.75% / 12). On a 30-year principal and interest basis, repayments would be about $3,243 a month. If the loan starts with five years interest only, repayments after that jump to about $3,454 a month, because the same balance is repaid over just 25 years.
The lower payment helps cash flow now. The trade-off is that you owe the full amount when the interest-only period ends, and the later repayment is higher. You can test your own numbers in a loan repayment calculator.

Understanding Negative Gearing Changes for Investors
Negative gearing means your rental costs exceed your rent, and the rules for using that loss depend on when you buy. Losses on properties held at 7:30pm AEST on 12 May 2026 remain deductible against other income, including wages. The same applies to eligible new builds bought after that date.
From the 2027-28 income year, net rental losses on established residential properties bought after that time can only be used against other residential property income. Excess losses can be carried forward. Interest remains deductible on the loan used for the rental property, but only the interest part of a repayment counts, not the principal part.
This matters because a tax refund is not a reliable way to fund a shortfall. Speak with your accountant about how these rules apply to you before you buy.
What Does a Rental Shortfall Look Like in Real Life?
A shortfall is the gap between rent and your total costs, and you fund it from your own income. Consider a single parent on one income who buys an established property with a loan at the illustrative 6.75% p.a. rate.
The lender counts 80 per cent of the expected rent, and the loan passes the serviceability test. After the first year, the property sits empty for six weeks between tenants, and a repair bill arrives. Because she kept a cash buffer in an offset account linked to the loan, she covers both without missing a repayment. The offset also reduces the interest charged while the money sits there.
The outcome is a manageable year rather than a crisis. The trade-off is that the cash in the offset is not working elsewhere, and offset features and fees vary between lenders. The lesson is to plan for empty weeks and repairs before you sign, and to hold a buffer sized to your own budget.
Borrowing Against Your Home Equity to Invest
You can sometimes use equity in your home as a deposit for an investment, but it increases your total debt and risk. Once total borrowing goes above 80 per cent of a property's value, lenders generally require Lenders Mortgage Insurance (LMI). LMI is paid by the borrower, and each lender sets its own limits.
The interest on the equity release is deductible only if the money is used to buy the investment. If you use some of it for personal spending, that part is not deductible. Keep investment and personal borrowing in separate loan accounts so the records stay clear, and ask your accountant to confirm the treatment.
Your home is then security for more debt. If the investment struggles, your family home is exposed. That is the main risk to weigh up first.
Choosing Between Fixed and Variable Rates
A variable rate moves with the market, while a fixed rate locks your repayment for a set period. Fixing gives certainty, which many single parents value. Fixed loans can also limit extra repayments and can carry break costs if you exit early, and these rules differ between lenders.
Some borrowers split the loan between fixed and variable. Ask any lender what features each part has, including offset access and extra repayments, before you decide.
Why Your Loan Structure Matters as Much as the Property
The right structure protects your family if life changes. If you ever struggle to pay, you can tell your lender about financial hardship, verbally or in writing, under the National Credit Code. This applies to regulated loans held by individuals. The lender has set time limits to respond and must give you AFCA contact details if it refuses.
It is worth knowing this protection exists, but it is a safety net, not a plan. A good structure reduces the chance you ever need it.
Our team can explain investment loans, compare lenders across Australia, and review whether refinancing could suit you later. If you already own a home, a loan health check is a sensible first step before using equity.
You have carried a lot on your own, and building wealth through property is a long game that should fit your life. Call one of our team or book an appointment at a time that works for you, and we will work through the numbers together.
Frequently Asked Questions
How much rent will a lender count on an investment property?
Lenders generally count no more than 80 per cent of expected rent. This allows for periods when the property is empty, and it does not cover costs like management fees or repairs.
Does an interest only loan increase how much I can borrow?
No. Lenders assess interest only loans as if you will repay principal and interest over the remaining term, so borrowing power does not rise. The trade-off is that the balance does not fall during the interest-only period.
Can I use my home equity to buy an investment property?
Often yes, depending on the lender and your circumstances. It increases your total debt and puts your home at risk, and LMI may apply if total borrowing goes above 80 per cent.
Are investment property losses still tax deductible?
It depends on when you bought. Rules changed for established properties acquired after 12 May 2026, with new limits from the 2027-28 income year. Speak with your accountant about your situation.
