If you’ve been watching Sydney’s property market lately, you already know the drill: prices stubbornly high, stock tight in the inner ring, and every serious buyer scrambling to squeeze out every dollar of borrowing capacity. Whether you’re hunting for your first home in Parramatta, upgrading in the Inner West, or looking at an investment in the Lower North Shore, your borrowing power is the number that determines what’s actually within reach.
The good news? There are real, practical moves you can make to lift that number — and most people haven’t done all of them.
What Lenders Actually Look At
Your borrowing power isn’t just about income. Banks and lenders run their own serviceability calculators, and they’re looking at a more complete picture than most people expect. Here’s what goes into the assessment:
- Gross income — base salary, overtime (if consistent), rental income, business income
- Existing debts — credit cards (assessed at the full limit, not just what you owe), car loans, personal loans, HECS/HELP debt
- Living expenses — declared expenses verified against your bank statements
- Dependants — each child adds to assessed living costs
- Buffer rate — APRA requires lenders to stress-test your loan at 3% above the current rate
That last point matters more than many buyers realise. If you’re applying for a loan at, say, 6.2%, the bank is checking whether you could still make repayments at 9.2%. That built-in buffer is why your maximum loan amount often feels lower than you expected.
The Easiest Win: Cancel Unused Credit
This is the single most underused lever, and it costs nothing to pull. Credit cards are assessed on their limit, not your outstanding balance. That $15,000 limit you barely touch is costing you roughly $75,000–$90,000 in borrowing capacity, depending on the lender.
Before you apply for a home loan, cancel or reduce the limits on any credit cards you don’t genuinely need. Same applies to buy-now-pay-later accounts — Afterpay, Zip, and similar products are now visible on credit files and factor into expense assessments at most lenders.
A client we worked with in Strathfield had three credit cards with a combined limit of $35,000 and used only one regularly. After cancelling two and reducing the third, her assessed borrowing power increased by over $150,000 — without changing a single dollar of her income.
Think About Your Income More Strategically
Lenders don’t treat all income equally. Base salary is typically 100% accepted. Overtime might be credited at 80% if it’s consistent and documented over two years. Rental income is often shaded to 80% to account for vacancies and costs.
If you’re self-employed or running a business, most lenders want two years of tax returns and will average the net profit figure across both years. Some lenders are more flexible — particularly with low-doc products or certain non-bank lenders — but your broker needs the full income picture to match you to the right product.
One commonly missed move: if your partner earns income but wasn’t planning to go on the loan, adding them as a co-borrower could significantly increase combined borrowing capacity. There are stamp duty and tax considerations to weigh up, but it’s worth modelling.
Lender Shopping: Not All Calculators Are Equal
This is where working with a broker pays for itself in real dollars. Different lenders apply different shading to income types, use different living expense benchmarks, and take different approaches to HECS debt — some deduct your full annual compulsory repayment, others use a lower figure.
The difference between lender A and lender B for the same applicant can be $80,000–$150,000 in maximum loan amount. In Sydney, that’s not a rounding error — it’s the difference between getting into a suburb and being locked out of it.
For buyers looking at the Hills District, the Northern Beaches, or anywhere in the Inner West, knowing which lender gives you the best run for your specific financial situation is genuinely valuable intelligence that a good broker can provide.
Clean Up Your Living Expenses (Legitimately)
Banks ask you to declare your monthly living expenses — and many then cross-check this against your bank statements. If your declared figure looks too low relative to what they can see, they’ll substitute their own estimate, which is usually higher.
There’s a legitimate version of this: if you have high discretionary spending you’d naturally cut once you have a mortgage — dining out four nights a week, multiple streaming services, gym memberships you barely use — consider genuinely trimming those three to six months before you apply. Your bank statements will reflect the lower spend, and your declared expenses will be defensible.
Don’t misrepresent your spending. But there’s nothing wrong with genuinely living more carefully ahead of a major purchase. Most buyers naturally do this anyway when saving a deposit.
The HECS Factor
For younger Sydney buyers, HECS-HELP debt is a significant drag on borrowing power. Lenders include your compulsory HECS repayment as a committed expense, reducing the net income available for loan repayments. Depending on your balance and income level, this can cut borrowing capacity by $30,000–$60,000.
If you have savings to pay down or clear your HECS balance before applying, it may be worth running the numbers — particularly if you’re near a repayment threshold. Your accountant and mortgage broker can help you model whether it’s better to use those savings on HECS or preserve them as part of your deposit.
Timing Your Application
When you apply matters. Lenders typically review the last three to six months of bank statements. If you’ve recently had an expensive period — a holiday, a wedding, a renovation — that spending shows up and inflates your assessed living expenses.
If your income has recently increased through a pay rise or a new role, some lenders will accept your current income immediately while others require three to six months of payslips at the new rate before they’ll count it. Knowing your lender’s policy and timing your application accordingly can make a material difference.
Get a Real Pre-Assessment Before You Bid
Before you bid at auction or sign a contract anywhere in Sydney, you need to know exactly where you stand. A solid pre-approval from the right lender — based on your complete financial picture, not a rough online calculator estimate — is the only reliable foundation for a confident purchase.
At Loan Connect, we work through your full income, liability, and expense profile, then match you to the lender whose policy gives you the best outcome for your situation. For a lot of our clients, that process reveals meaningfully more capacity than they expected — or pinpoints exactly what to address before they’re ready to apply.
If you’re planning to buy in Sydney over the next three to twelve months, the time to have this conversation is now — well before you find the property. Call us on 1300 855 155 or get in touch online and we’ll run the numbers for your specific situation.
