A lot of buyers in Perth hit the same frustrating point. They have a deposit, they have a property in mind, and then the number a lender is willing to offer comes in lower than expected. That is why understanding the real ways to improve borrowing capacity matters early – not after you have already started making offers.
Borrowing capacity is not just about your salary. Lenders look at your income, yes, but they also assess your existing debts, living expenses, credit conduct, dependants, loan term, interest rate buffers and the type of property you want to buy. Small changes in the right areas can make a meaningful difference. The key is knowing which changes are likely to help, and which ones may not move the needle much at all.
What lenders are really looking at
When a lender calculates how much you can borrow, they are trying to answer one question: can you comfortably afford the repayments not just now, but if rates rise or your circumstances change?
That is why banks and lenders do not simply take your current mortgage repayment estimate and compare it to your payslips. They usually assess your application at a higher interest rate than the actual product rate. They also review your regular spending, credit card limits, personal loans, HECS or HELP debt, car finance and any other commitments that reduce your surplus income.
For first-home buyers, this can come as a surprise. For investors and refinancers, the challenge is often that one lender’s policy can produce a very different outcome from another’s. Borrowing power is not identical across the market.
1. Reduce unsecured debt first
One of the most effective ways to improve borrowing capacity is to reduce or clear unsecured debt before applying. Credit cards, personal loans, car loans and buy now, pay later accounts can all cut into how much a lender will offer.
Credit cards are a common issue because lenders usually assess the full card limit, not just the amount owing. If you have a card with a $15,000 limit and rarely use it, that limit can still reduce your borrowing power. The same applies to store finance and interest-free purchases.
Paying down these debts can improve your position quickly. Closing unused facilities can help too, provided the account is fully shut rather than just left open with a nil balance.
2. Tighten spending before you apply
Lenders now look closely at living expenses, and bank statements matter. If your recent spending shows frequent overdrawing, heavy discretionary purchases or irregular cash flow, that can affect serviceability.
This does not mean you need to live on baked beans for three months. It does mean that a clear, consistent budget helps. Reducing non-essential spending, avoiding large once-off splurges and showing a stable savings pattern can strengthen your application.
For some households, the gain is not only in the numbers. Better spending habits also make it easier to manage repayments once the loan starts, which is just as important as getting approved in the first place.
3. Review your credit card limits, not just balances
This point deserves separate attention because it is often overlooked. A borrower may proudly pay off a card, only to find their borrowing capacity barely changes because the limit stayed the same.
If you have multiple cards, consider whether you really need them all. Reducing limits or closing surplus accounts can improve your borrowing position. The trade-off is that fewer credit facilities may mean less short-term flexibility, so this should be planned rather than done in a rush a week before applying.
4. Keep your repayment history clean
Good repayment conduct still matters. Missed payments on loans, credit cards or even some utilities can raise questions for lenders and narrow your options.
If your credit file has minor issues, not every lender will look at it the same way, but prevention is far better than explanation. Paying every commitment on time, avoiding dishonours and keeping direct debits well funded can protect both your credit profile and your borrowing power.
If there has been a past issue, it is usually better to address it early and understand how long ago it occurred, whether it has been corrected and which lenders may still be open to your application.
5. Make sure all income is usable
Not all income is treated equally by lenders. Base salary is usually straightforward, but overtime, bonuses, commissions, casual income, rental income and self-employed earnings may be shaded or assessed under stricter rules.
This is where preparation matters. If you are relying on variable income, strong documentation can make a difference. Recent payslips, group certificates, tax returns and clear account statements help show consistency. Self-employed borrowers often need up-to-date financials and tax returns, and timing can be crucial if a stronger year has not yet been lodged.
Sometimes the best result comes from waiting until income is more clearly evidenced rather than applying too early. It depends on your circumstances, your industry and the lender’s policy.
6. Choose the right loan term and structure
Loan structure affects borrowing capacity more than many buyers realise. A longer loan term usually reduces the assessed monthly repayment, which may improve serviceability. That does not mean a longer term is always the right long-term financial move, but it can help create borrowing room.
Likewise, if you are rolling several debts into one refinance, the new structure may improve monthly cash flow and borrowing position. On the other hand, stretching short-term debt over a long mortgage can mean paying more interest over time. Better capacity today should still be weighed against the total cost tomorrow.
This is where tailored advice matters. A structure that suits a first-home buyer may not suit an investor or a growing family planning future changes in income.
7. Avoid major finance applications before a home loan
If you are planning to buy property soon, it is usually wise to avoid taking on new debt first. Financing a car, increasing a credit card limit or applying for multiple consumer loans can reduce your borrowing capacity and complicate your file.
Even if a new debt seems manageable in your day-to-day budget, lenders assess it formally. A car loan in particular can have a noticeable effect on serviceability. If the property purchase is the priority, delaying other finance can be a smart move.
The same logic applies to multiple credit enquiries. They do not always cause a problem on their own, but several recent applications can make a lender look more closely at your position.
8. Check how dependants and household income are presented
Household composition affects borrowing power. Dependants generally increase the living expense side of the assessment, while a second income may strengthen it. But not every lender treats these details the same way.
For couples, the way income is split, whether one applicant is on parental leave, and whether there are childcare costs can all influence the result. For single applicants, showing stable finances and realistic living expenses is especially important.
This is one area where lender choice can make a real difference. Some lenders are more favourable than others for certain family setups, professions or income mixes.
Ways to improve borrowing capacity through better preparation
Good preparation is often the difference between an average result and a strong one. Before applying, it helps to gather payslips, bank statements, identification, details of current debts, evidence of savings and any supporting documents for extra income. Clean, complete paperwork makes it easier for a lender to understand your position and assess it efficiently.
It also helps to be realistic about your figures. Understating expenses or forgetting liabilities can cause delays, valuation issues or problems later in the process. A well-prepared application gives lenders confidence.
Why lender selection matters
Not all borrowing assessments are created equal. One lender may be conservative on overtime income, another may take a more practical view. One may assess living expenses in a way that limits a growing family, while another may be more flexible. The difference can be substantial.
That is why borrowers who go straight to a single bank do not always see the full picture. A broker who understands policy differences can identify where your scenario may fit best and whether there are practical ways to improve borrowing capacity before submission.
For Perth buyers, especially first-home buyers juggling deposit goals, rising living costs and tight timelines, that kind of guidance can remove a lot of guesswork. Aspire Mortgage Services works with a broad lender panel, which can be helpful when one policy does not suit an otherwise solid borrower.
When borrowing more is not the main goal
There is one final point worth keeping in mind. Improving borrowing capacity is useful, but borrowing to your absolute maximum is not always the best outcome. A lender may approve a certain figure, but your comfort level matters just as much.
If stretching to the top of your limit leaves no room for rate rises, family changes or everyday life, a lower purchase price may put you in a stronger long-term position. The best lending strategy is not only about what you can borrow. It is about what you can repay with confidence, now and as life changes.
