If a lender has told you that you can borrow less than expected, the gap usually comes down to a few assessable numbers – income, debts, living expenses, deposit size, and the way your loan is structured. The good news is that 10 ways to increase your home loan borrowing power are often more practical than people think, especially when you plan ahead before submitting an application.
Borrowing power is not just about how much you earn. Lenders also look at how reliably you manage money, how much of your income is already committed elsewhere, and how much buffer they believe you can handle if rates rise. That means small changes can make a meaningful difference, but the right move depends on your timeline, property goals, and overall financial position.
What lenders are really assessing
Before looking at the strategies, it helps to understand the lens lenders use. They are not asking, “Can you afford the current repayment today?” They are asking, “Can you still afford this loan if interest rates rise, expenses increase, or your income changes?”
That is why borrowers with solid incomes can still be capped by credit card limits, personal loans, childcare costs, or spending patterns that look high on bank statements. On the other hand, someone with a modest income but clean conduct, low debts, and strong savings habits may be assessed more favorably.
10 ways to increase your home loan borrowing power
1. Reduce or clear unsecured debts first
Personal loans, car loans, buy now pay later accounts, and credit cards can drag down borrowing power faster than most borrowers expect. Lenders treat these commitments seriously because they reduce your monthly surplus income.
Paying out a personal loan before applying can improve your position immediately. If that is not possible, even reducing the balance and shortening the list of active debts can help. The key is timing – if you are close to applying, avoid taking on any new unsecured debt unless it is essential.
2. Lower your credit card limits, not just your balances
This is one of the most overlooked steps. Many borrowers assume a card with a zero balance has no impact. In lending assessments, the approved limit often matters more than what you currently owe.
For example, a borrower with two unused cards totaling $20,000 in limits may be assessed as if that debt could be drawn at any time. Reducing limits or closing unnecessary cards can improve your borrowing capacity without changing your income at all. Just make sure the closure is processed properly and reflected before the application goes in.
3. Review your living expenses honestly
Lenders compare the expenses you declare with what appears in your transaction history and with benchmark household spending measures. If your account statements show frequent discretionary spending, subscriptions, dining, or shopping that pushes your monthly outgoings up, it can affect your result.
This does not mean you need to stop spending altogether for six months. It means you should understand your baseline and tighten habits where it makes sense. A cleaner pattern of spending can strengthen both borrowing power and lender confidence. The important part is that your declared budget needs to be realistic and supportable.
4. Increase your deposit if you can
A larger down payment does more than reduce the loan size. It can also lower the lender’s risk, improve your loan-to-value ratio, and in some cases help you avoid mortgage insurance.
That combination can make approval easier and broaden the range of lenders and products available to you. If you are close to a key threshold, waiting a little longer to save more may produce a better outcome than rushing in now. The trade-off, of course, is market movement – in some areas, property prices may rise while you are saving, so this needs a balanced view.
5. Check whether all of your income can be used
Not all income is assessed the same way. Base salary is usually straightforward, but bonuses, overtime, commission, rental income, self-employed earnings, and casual income may be shaded or averaged over time.
That is where lender choice matters. One lender may take a more conservative view, while another may accept a higher percentage of your variable income if the history is strong. If you earn more than a simple salary, the structure of your application can be just as important as the amount you earn.
6. Improve your credit profile before applying
A strong credit profile supports the rest of your application. Missed payments, arrears, defaults, or too many recent credit inquiries can raise concerns, even if your income is good.
Start by checking your credit report for errors. Then focus on paying every commitment on time and avoiding multiple loan applications across different lenders. A rushed approach can weaken your file. A more measured process usually gives you a cleaner path and a better chance of presenting well from the start.
Small structural changes can have a big effect
Many borrowers assume borrowing power is fixed. It is not. The way your debts, income, and application are arranged can shift the result more than expected.
7. Consider applying with a co-borrower carefully
Adding a second borrower can increase combined income and improve borrowing capacity, but it is not automatically better. The second applicant’s debts, credit profile, dependents, and spending also come into the assessment.
For some couples, a joint application is clearly stronger. In other cases, a single application may be cleaner, especially if one borrower has complex liabilities or irregular financial conduct. This is one of those areas where it really depends on the full picture rather than a rule of thumb.
8. Refinance or restructure existing debts
If you already own property, refinancing existing loans may improve your cash flow and position before your next purchase. Lowering monthly repayments on current debts, consolidating higher-cost liabilities, or restructuring loan terms can make your numbers work better in serviceability calculations.
This needs to be handled carefully. Extending loan terms may help assessment but can increase total interest paid over time. Debt consolidation can simplify cash flow, but only if it is paired with disciplined spending. The short-term borrowing benefit should still align with your longer-term financial plan.
9. Choose a lender whose policy fits your scenario
This is one of the biggest differences between going directly to one bank and comparing options properly. Lenders do not all assess borrowing power the same way. Their treatment of overtime, bonus income, self-employment, rental income, existing debts, and living expenses can vary significantly.
For borrowers in higher-priced markets like Sydney, these differences can be material. A lending policy that better fits your income mix or property strategy can mean the difference between falling short and moving forward confidently. This is where broker guidance can save time and prevent unnecessary declines.
10. Avoid major financial changes right before applying
Changing jobs, financing a new car, applying for extra credit, or making large unexplained transactions shortly before a mortgage application can complicate assessment. Even positive changes, such as becoming self-employed or moving into a higher-paying role, may require more evidence before a lender will fully count the income.
If you know a home purchase is coming, try to keep your finances stable in the lead-up. Consistency helps. Lenders generally prefer a clear, predictable profile over one with a lot of last-minute movement.
How to prioritize the right changes
Not every strategy will be worth the effort for every borrower. If your income is strong but your monthly commitments are high, debt reduction may give you the best result. If your income is more complex, the real opportunity may be choosing a lender that assesses it more favorably. If your issue is a small deposit, waiting and saving may open up far better options.
This is also why online calculators only tell part of the story. They can be useful for a rough estimate, but they rarely reflect the full range of lender policy differences or the practical impact of structuring choices.
A guided review can identify which adjustments are likely to move the needle fastest and which ones are not worth chasing. At Credific Finance, that usually means looking at the whole file early – income, debts, expenses, credit profile, deposit position, and lender fit – so borrowers can improve their position before the application reaches a credit assessor.
If you are trying to buy soon, the goal is not to game the system. It is to present a stronger, more accurate application that shows you can comfortably manage the loan you want. The more intentional your preparation, the more options you usually have when it is time to move.
