How to Increase Borrowing Capacity When Buying in Brisbane South in 2026: 9 Practical Ways

Buying, investing or refinancing in Brisbane's South? We can help, just get in touch here.

For many Australians buying in 2026, especially in fast-growing areas like Brisbane South, borrowing capacity can make or break homeownership goals. With rising property prices, tightening lending conditions, and higher living costs, knowing how to increase your borrowing capacity is more important than ever.

Borrowers typically encounter this challenge during pre-approval or while house-hunting, often realising too late that their loan limit doesn’t align with market prices. A common misconception? That income alone dictates your borrowing power. In reality, lenders use complex calculations based on your income, debt, living expenses, and credit profile.

This is where a mortgage broker plays a crucial role. At AE Finance Solutions, our Brisbane South brokers can guide you through lender criteria, recommend loan strategies, match you with the right lenders, and help you unlock greater borrowing potential.

Let’s walk through how to boost your borrowing capacity the right way.

What Is Borrowing Capacity?

Borrowing capacity, or borrowing power, refers to how much a lender is willing to let you borrow for a home loan. It’s calculated based on factors such as your income, living expenses, existing debts, credit history, and current interest rates. Lenders may also consider your deposit size, employment type, and whether you’re applying on your own or with a co-borrower when assessing your overall borrowing limits.

What Factors Influence Borrowing Capacity?

When lenders assess your borrowing power, they look well beyond your income. Here’s what really matters in 2026:

Your Income and Stability: Stable, consistent income from full-time or permanent part-time employment is viewed most favourably. Bonuses, commissions, rental income, and government benefits may be included, but often only partially.

Living Expenses: Australian lenders follow Household Expenditure Measure (HEM) guidelines, but your actual declared expenses are scrutinised too. Overspending on discretionary items or maintaining multiple subscriptions can reduce borrowing power.

Existing Debt Commitments: Credit cards (even unused ones), personal loans, car finance, and BNPL services like Afterpay affect your borrowing calculation. Even a credit card with a $10,000 limit can reduce your loan capacity by several tens of thousands.

Number of Dependents: Having children or financially dependent family members increases your living expenses and can reduce borrowing capacity.

Loan Term and Interest Rates: The shorter the loan term, the higher the repayments, reducing your serviceability. Lenders also assess your ability to repay at a higher ‘buffer’ rate (usually 3% above the actual rate), especially important as rates fluctuate.

Steps to Increase Your Home Loan Borrowing Capacity

Below are 9 proven strategies to boost your borrowing capacity when buying in Brisbane South this year.

1. Pay Off or Reduce Credit Card Limits

Even if your balance is $0, lenders calculate your repayment capacity using the limit, not the balance. Reduce limits or close unused cards.

2. Consolidate Debts Where Appropriate

Merging smaller debts into one personal loan with lower repayments can improve serviceability. But this must be done carefully; speak with a broker first.

3. Boost Your Income

This could mean increasing hours, taking on a second job, or adding a stable side income. Rental income from investment properties or boarders may also count, depending on the lender.

4. Cut Unnecessary Spending

Temporarily reduce lifestyle spending—Uber Eats, gym memberships, streaming subscriptions—and show a lower monthly outflow for 3–6 months before applying.

5. Wait Until Probation Ends

Most lenders prefer borrowers to be out of probation. Waiting a few months could improve your approval odds and capacity.

6. Choose a Longer Loan Term

A 30-year loan term results in lower monthly repayments, which boosts your borrowing capacity.

7. Consider a Guarantor Loan

For some first-home buyers, a guarantor can reduce the deposit needed and increase borrowing power, but it’s not suitable for everyone.

8. Use a Professional Package or LMI Waiver

Certain professions (like doctors, accountants) may access Lenders Mortgage Insurance (LMI) waivers and higher borrowing limits.

9. Work with a Mortgage Broker Early

A broker can help you structure your application to meet lender criteria, avoid costly mistakes, and improve your overall profile.

FAQs About Increasing Borrowing Capacity

How do lenders calculate borrowing capacity in Australia?

Lenders consider your income, debts, credit history, living expenses, number of dependents, and apply a ‘stress test’ to assess how much you can borrow safely.

Does reducing credit card limits increase borrowing power?

Yes. Lowering or cancelling credit cards can significantly improve your borrowing capacity, as lenders assess repayments based on the card's limit, not balance.

Can rental income be used to increase borrowing capacity?

Generally, yes, though lenders often apply a discount (e.g., only counting 70–80% of rent) to account for vacancies and costs.

Will cutting subscriptions and lifestyle expenses really help?

Yes, especially if you can demonstrate 3–6 months of reduced outgoings. This strengthens your living expense profile.

Do lenders treat casual or contract income differently?

Yes. Casual and contract workers often need at least 12 months of consistent income to be assessed favourably, though some lenders are more flexible.

Is it better to apply with a broker or directly with a bank?

Applying with a broker can improve your chances. Brokers understand which lenders suit your profile and help avoid application mistakes.

Can guarantors help increase borrowing capacity?

Yes, in some cases. A guarantor can boost borrowing power and reduce the deposit required, though it does come with risks for both parties.
