How Can I Improve My Borrowing Capacity Before Applying?

By Rajesh Kandel, Everest Home Loans 11 September 2026 10 min read

If you are asking, how can I improve my borrowing capacity before applying, start with the parts of your finances a lender can verify: your income, regular debts, credit limits, household spending, savings pattern, and credit history. The goal is not simply to look better on paper. It is to show that you can comfortably manage a home loan repayment even if interest rates rise.

Borrowing capacity is the amount a lender may be willing to lend after completing a serviceability assessment. This assessment compares your verified income with your existing commitments and living costs, then tests whether there is enough money left for the proposed mortgage repayment at the lender's assessment rate.

Small changes can make a meaningful difference. But timing matters. Paying off a card one day before applying may not carry the same weight as showing several months of consistent financial habits in your bank statements.

The short answer

Improve borrowing capacity by lowering credit limits and debt repayments, keeping spending stable before applying, protecting your credit report, documenting reliable income, and choosing a lender whose policy suits your circumstances. A larger deposit can improve approval options, but it does not always increase serviceability directly.

Understand What Limits Your Borrowing Capacity

Serviceability is more than your salary

A lender does not usually assess borrowing power by taking your income and subtracting only your current rent or bills. It applies its own rules to estimate whether you could repay the proposed loan under more conservative conditions.

This is why a person with a solid income can still have limited borrowing capacity. For example, two applicants may earn the same amount, but one has a $35,000 car loan, two credit cards, Buy Now Pay Later accounts, and high recurring household spending. Their assessed surplus income can be much lower.

Assessment rates and expense benchmarks matter

Lenders generally test repayments at a higher rate than the rate you expect to pay. This creates a buffer for potential rate rises and is one reason calculator results can differ from an actual approval decision.

Lenders may also compare your declared household expenses with a living expense benchmark. If your declared figure seems unrealistically low for your household size, location, or spending pattern, the lender may use a higher estimate instead.

That means cutting spending only on the application form is unlikely to help. Your statements need to tell the same story. A household that reports low monthly expenses but regularly spends heavily on dining, subscriptions, transfers, or shopping may be asked to explain the difference.

Your financial profile is assessed as a whole

There is no universal dollar figure for how much each change will increase borrowing capacity. Different lenders assess income types, expenses, and debts differently. Loan Market notes that lender policy can affect how income, liabilities, and credit applications are assessed, which is why comparing the right options matters before lodging an application. See its guidance on steps that may improve borrowing power.

A modest income increase may have less impact than removing a major repayment. In another situation, a lender's treatment of overtime income or family expenses could matter more than either change. I recommend identifying the actual constraint first rather than making random financial changes.

Reduce Commitments That Shrink Serviceability

Lower credit card limits, not just balances

Unused credit can reduce borrowing capacity because many lenders assess a credit card based on its limit, not simply the amount currently owing. A card with a $10,000 limit may be treated as an available commitment even if the balance is zero.

This is the part many applicants miss. Paying a $5,000 balance down to zero improves your position, but leaving the $10,000 limit open may still affect serviceability. Reducing the limit or closing a card can have a stronger effect when the card is no longer needed.

Australian borrowing guidance explains that lenders can treat a card limit as an ongoing commitment, so it can be useful to reduce credit card limits before a home loan application rather than focusing only on the outstanding balance.

Before closing anything, consider the tradeoff. Keep a modest card limit if it supports everyday cash flow and you can manage it responsibly. Close or reduce facilities that are rarely used, expensive, or likely to encourage further borrowing. Also allow time for the change to appear in your documentation and credit file where relevant.

Pay down loans with monthly repayments

Personal loans and car loans usually affect borrowing capacity through their required monthly repayments. This can make debt reduction more powerful than it first appears.

A $10,000 loan balance does not reduce capacity by $10,000 alone. The lender focuses on the repayment obligation and how it reduces your monthly surplus. If the loan has a short remaining term or high repayment amount, clearing it may improve serviceability more than paying the same $10,000 into a deposit account.

Defence Bank's guide to increasing borrowing power also highlights card limits, existing debts, credit history, spending, income, and deposit size as factors worth reviewing together.

Review BNPL, HELP, and tax liabilities carefully

Buy Now Pay Later facilities may be assessed as a liability, a recurring expense, or a sign of regular consumer credit use, depending on lender policy. Closing inactive accounts and paying outstanding amounts may simplify your application, particularly if transaction statements show frequent repayments.

HELP or HECS debt can also affect serviceability. It is not always treated the same way by every lender because repayment obligations depend on taxable income and lender policy. Paying it off voluntarily could improve capacity where that liability is included in the lender's calculation, but it is not automatically the best use of your cash.

For instance, if clearing HELP would leave you short of the deposit, stamp duty, legal costs, and an emergency buffer, the overall application may become weaker. DPM Financial discusses early HELP repayment and reducing credit or BNPL facilities as possible strategies, but the right choice depends on the lender and your available funds.

Build Stronger Income, Savings, and Spending Evidence

Give your bank statements time to reflect new habits

Lenders commonly request recent transaction statements. The exact period varies, so there is no single guaranteed timeline. Still, a clean and consistent statement pattern is generally more persuasive than a last minute spending cut.

If you plan to apply soon, start treating the next few statement cycles as part of your application file. That does not mean you cannot spend money. It means your spending should be realistic, stable, and easy to explain.

A useful test is simple: if a lender saw this month's statements without context, would your financial habits support the expenses declared in your application?

Increase income only when it can be verified

More income can improve borrowing capacity, but only if the lender accepts it and you can document it. A recent pay rise may be helpful once it appears in your payslips or employment letter. Overtime, commissions, bonuses, allowances, and second jobs may be accepted differently across lenders.

CommBank's borrowing power calculator guidance identifies reducing expenses, paying off debts, improving credit, and increasing income as factors that can lift an estimate. Treat any calculator output as a planning tool, not a loan offer.

For self employed applicants, documentation quality is especially important. Up to date tax returns, notices of assessment, business financials, and business bank statements can help demonstrate consistent income. If your business income has recently improved, the lender may still rely on a longer income history or use a conservative figure. Avoid assuming that a strong recent month will replace established evidence.

Protect your credit profile before lodgment

Your credit score is one part of your financial health. Paying bills and repayments on time, correcting report errors, and avoiding missed obligations can support a stronger application. Review your credit report early enough to dispute any incorrect defaults or enquiries before applying.

Also avoid making several credit applications while preparing for a mortgage. A credit enquiry can appear on your report even if you do not proceed with the finance or draw down the money. This matters because a cluster of recent applications can raise questions about financial stress or changing circumstances.

Save a deposit for flexibility, not just capacity

A larger deposit lowers the amount you need to borrow. It can also reduce your loan to value ratio, known as LVR. For example, borrowing $720,000 on an $800,000 property is a 90% LVR, while borrowing $640,000 with a $160,000 deposit is an 80% LVR.

Reaching a lower LVR may improve pricing, reduce lenders mortgage insurance in some cases, and strengthen approval prospects. However, a larger deposit does not always raise borrowing capacity directly. If serviceability is the issue, the lender may still cap the loan amount based on income, debts, and expenses.

Keep enough cash for purchase costs and a sensible emergency buffer. Draining every dollar to reach a deposit target can create a different risk: an application with no financial cushion.

Key Takeaways

Prioritise changes by their likely impact

I would focus on financial changes in this order:

1. Identify the binding issue. Is your limit caused by debt repayments, card limits, living expenses, insufficient accepted income, or deposit size?
2. Remove high impact monthly commitments. Car loans, personal loans, large card limits, and BNPL accounts can reduce assessed surplus income.
3. Show stable behaviour before applying. Let your bank statements reflect your improved spending and savings habits.
4. Protect your credit report. Pay on time, check for errors, and avoid unnecessary applications for new credit.
5. Prepare evidence for every income source. This is essential for variable income, bonuses, overtime, and self employed income.
6. Match the application to lender policy. The lender with the lowest advertised rate is not always the lender that will assess your income and commitments most favourably.

The fastest improvement is often not earning more. It is removing a repayment or credit limit that is reducing your assessed monthly surplus.
