How Much Can I Actually Borrow? How to Boost Your Borrowing Power Before You Apply

What Borrowing Power Really Means

The first question almost every buyer asks is simple: how much can I actually borrow? It is the number that shapes your property search, deposit target, repayment comfort and confidence when making an offer.

Borrowing power is the estimated amount a lender may be willing to lend you after assessing your full financial position. It is also called borrowing capacity, mortgage borrowing capacity, home loan borrowing power or loan serviceability.

Many buyers assume borrowing power is mostly about salary. Income is important, but it is only one part of the assessment. Lenders also review your household expenses, existing debts, credit card limits, dependants, deposit, employment type, repayment history and the type of loan you want.

This is why two people earning the same income can receive very different borrowing outcomes. One applicant may have no personal loans, low credit card limits, controlled spending and a strong deposit. Another may have multiple credit cards, a car loan, high discretionary spending and recent credit enquiries. Even with the same income, their borrowing capacity may be very different.

Your borrowing power can also vary between lenders. Each bank or lender may treat income, expenses, overtime, bonuses, self-employed income, rental income and existing debts differently. One lender may be more suitable for a first home buyer, while another may be more suitable for a refinancer, investor or self-employed borrower.

How Lenders Calculate How Much You Can Borrow

Lenders calculate how much you can borrow by testing whether you can afford the proposed home loan repayments after allowing for your income, existing debts, living expenses and a buffer for potential interest rate changes. This process is commonly called a serviceability assessment.

In Australia, lenders generally do not assess your application only at the advertised interest rate. They usually test your ability to repay using a higher assessment rate. This helps the lender check whether the home loan would still be affordable if interest rates increased or your financial circumstances changed.

This is one reason many borrowers are surprised by their borrowing capacity. They may feel comfortable with repayments at the current advertised rate, but the lender is assessing them at a higher rate for approval purposes.

When assessing home loan borrowing power, lenders commonly review:

• Income: Salary, wages, overtime, commission, bonuses, allowances, rental income, business income and acceptable secondary income.
• Employment: Your job type, employment history, probation status, industry, income stability and length of time in your role.
• Living expenses: Groceries, utilities, transport, insurance, childcare, school fees, medical costs, subscriptions and lifestyle spending.
• Existing debts: Personal loans, car loans, credit cards, buy now pay later accounts, store finance, overdrafts and other repayments.
• Credit limits: Approved limits on credit cards and other credit facilities, even when the current balance is low.
• Dependants: Children or other dependants can increase assessed household living costs.
• Deposit and savings: Your available deposit, genuine savings history, equity, gifted funds and funds available for purchase costs.
• Credit conduct: Repayment history, credit enquiries, defaults and signs of financial stress.
• Loan purpose: Owner-occupied purchase, investment purchase, refinance, construction loan or equity release.
• Loan structure: Principal and interest, interest-only, fixed rate, variable rate, split loan, offset account and loan term.

The Debt-to-Income Reality

Debt is one of the biggest reasons borrowers are approved for less than expected. Even when your income is strong, existing debts can reduce the income available for a new home loan. This can lower your borrowing power and narrow your property budget.

Lenders look at your overall debt position to assess risk. If your existing repayments are already high compared with your income, the lender may decide that taking on a larger mortgage would place too much pressure on your household cash flow.

Credit Card Limits Matter, Not Just Balances

Credit cards are one of the most misunderstood parts of borrowing capacity. Many borrowers assume a credit card does not matter if the balance is low or paid off each month. In reality, the approved limit can still reduce your borrowing power.

If you have a credit card with a $15,000 limit and only owe $500, the lender may still consider the risk that you could use the full $15,000 limit after your home loan is approved. This means unused credit card limits can still reduce the amount you may be able to borrow.

Before applying for a home loan, review every credit card and ask:

• Do I still need this card?
• Is the limit higher than I realistically need?
• Could a lower limit improve my borrowing capacity?
• Should I close an unused credit facility?
• Have I made all repayments on time?

Reducing or closing unnecessary credit card limits may help improve your home loan borrowing power. However, it should be done carefully because you still need enough financial flexibility for genuine emergencies and cash flow management.

Personal Loans and Car Loans Can Heavily Reduce Borrowing Capacity

Personal loans and car loans can significantly reduce borrowing power because the repayments are fixed commitments. Even if the remaining balance is not large, the monthly repayment can reduce the income available for a mortgage.

For example, a car loan repayment of $700 per month can make a noticeable difference to your borrowing capacity. The lender has to include that repayment in your serviceability assessment before calculating how much you can borrow for a home loan.

If you are preparing to buy, review whether your existing debts should be paid down, paid out, refinanced or left unchanged. The best option depends on your full financial position.

Paying out a personal loan may improve borrowing power, but using too much of your deposit to clear debt may reduce your funds available for the purchase. A mortgage broker can help compare the impact of different options before you apply.

Buy Now Pay Later and Small Debts Still Matter

Buy now pay later accounts, store finance, overdrafts, phone repayment plans and small personal debts can also affect how lenders view your application. Individually, these may seem minor. Together, they may suggest higher spending commitments or weaker cash flow control.

Before applying, consider closing unused facilities and clearing small debts where practical. This can reduce lender questions, simplify your statements and make your financial position easier to assess.

Avoid New Debt Before Applying

Taking on new debt shortly before applying for a home loan can reduce your borrowing capacity and add fresh credit enquiries to your credit file. If you are planning to apply soon, avoid unnecessary applications for credit cards, car finance, personal loans or store finance.

A clean and stable financial profile is usually stronger than one with recent debts, new repayment commitments and multiple credit checks.

The Three-Month Household Budget Audit

Your bank statements tell a story. Before approving a home loan, lenders may review your income deposits, spending habits, savings behaviour, account conduct and regular commitments. This makes the three months before applying especially important.

A household budget audit helps you understand where your money is going and gives you time to improve the way your finances appear under lender scrutiny.

Step 1: Review Your Real Spending

Start with your actual bank statements, not your ideal budget. Go through the last three months of transaction and credit card statements and group your spending into clear categories.

• Rent or board
• Groceries and household supplies
• Utilities, phone and internet
• Insurance premiums
• Fuel, parking, tolls, public transport and vehicle costs
• Childcare, school fees and child-related expenses
• Medical and health costs
• Subscriptions and memberships
• Takeaway, restaurants, coffee and entertainment
• Shopping, clothing and personal spending
• Travel, holidays and hobbies
• Cash withdrawals and transfers
• Loan repayments and credit card repayments

This exercise can be eye-opening. Many borrowers know their major bills but underestimate everyday spending. Small transactions repeated often can reduce monthly surplus income and affect borrowing power.

Step 2: Trim Discretionary Spending for Three Months

Discretionary spending is not automatically bad. Lenders understand that people need to live. However, high discretionary spending can reduce your assessed surplus income and may lead to more questions during assessment.

For at least three months before applying, consider reducing:

• Frequent takeaway and dining out
• Online shopping
• Unused subscriptions
• Large cash withdrawals without a clear purpose
• Expensive entertainment spending
• Non-essential travel costs
• Impulse purchases
• Unnecessary app, streaming or membership payments

The goal is not to create an unrealistic lifestyle. The goal is to show that you can manage cash flow in a way that supports a home loan repayment.

Step 3: Create Cleaner Bank Statements

Cleaner bank statements can make your home loan application smoother. A lender should be able to quickly understand where your income comes from, where your money goes and whether your accounts are being managed responsibly.

Aim to show:

• Salary or business income being deposited consistently
• Bills paid on time
• No dishonours or failed direct debits
• Regular savings transfers
• Reduced discretionary spending
• Clear explanations for large one-off transactions
• Minimal unnecessary transfers between accounts

If your statements are messy, the lender may ask more questions. More questions can mean more documents, more delays and more stress. A simple account history makes the assessment easier.

Step 4: Build or Protect Genuine Savings

Your deposit matters, but lenders may also look at how the deposit was built. Regular savings can demonstrate discipline and show that you can manage money consistently.

If possible, set up an automatic transfer into a savings account each payday. Keep those savings separate from everyday spending. If your deposit includes gifted funds, inheritance, sale proceeds or other lump sums, keep records so you can prove where the money came from.

If you are a first home buyer, you may also want to review first home buyer loan options and available support pathways before deciding how much deposit you need.

Income Maximisation

Improving borrowing power is not only about reducing debts and expenses. It is also about making sure your income is presented clearly and supported with the right documents.

Many borrowers earn more than a base salary. They may receive overtime, bonuses, commission, allowances, rental income, business income, government payments or secondary income. These income streams may help your borrowing capacity if they are acceptable to the lender and properly documented.

Base Salary and Wages

Base salary is usually the simplest income type for lenders to assess. If you are a permanent full-time or part-time employee, recent payslips and your income statement may be enough to verify your income.

To prepare, gather:

• Recent payslips
• Your employment contract, if available
• Your most recent income statement or tax return
• Evidence of any recent pay rise
• Bank statements showing salary credits

If you recently started a new job or received a pay rise, the lender may ask for extra evidence to confirm that the income is permanent and ongoing.

Regular Overtime

Overtime can support borrowing power when it is consistent and well documented. However, lenders may not always use 100% of overtime income. Some may average it over a period, use only part of it or require a minimum history.

If overtime is part of your income, prepare:

• Several recent payslips showing overtime
• Year-to-date income figures
• Prior year income evidence, if available
• An employer letter confirming overtime is regular, if required

The more consistent the overtime pattern, the easier it may be for a lender to include it in the borrowing power assessment.

Bonuses and Commissions

Bonuses and commissions can help your application, but lenders usually want to see a track record. A one-off bonus may not carry the same weight as regular annual, quarterly or monthly bonus income.

Useful documents include:

• Payslips showing bonus or commission payments
• Your employment contract or commission structure
• Previous income statements
• Tax returns, if required
• Evidence showing the income has been received consistently

Do not assume every lender will treat variable income the same way. Lender selection can make a meaningful difference to how much you can borrow.

Allowances

Allowances may include car allowance, travel allowance, site allowance, shift allowance, meal allowance, uniform allowance or industry-specific payments. Some allowances may be accepted as income. Others may be treated as reimbursements or excluded.

To improve your position, document:

• What the allowance is for
• Whether it is taxable or non-taxable
• How regularly it is paid
• Whether it appears on payslips
• Whether it is expected to continue

The clearer the evidence, the easier it is for the lender to assess the income correctly.

Secondary and Tax-Free Income Streams

Some borrowers receive secondary income from rental properties, casual work, freelance work, government payments, investment income or family assistance. Some income may be tax-free or treated differently depending on the source and lender policy.

These income streams may help your borrowing power if they are ongoing, acceptable and properly documented. Lenders may request:

• Lease agreements and rental statements
• Bank statements showing regular deposits
• Tax returns and notices of assessment
• Invoices or business records
• Government benefit statements, where applicable
• Accountant letters for self-employed or business income

If you are using rental income or equity to buy another property, visit the property investment loans page to learn more about investment loan structure and deposit strategies.

Self-Employed Income

Self-employed borrowers can still access competitive home loan options, but they usually need stronger preparation. Lenders may review taxable income, business stability, cash flow, liabilities and how consistent the income has been over time.

If you are self-employed, prepare early by organising:

• Personal tax returns
• Business tax returns
• Financial statements
• Business bank statements
• BAS statements, where applicable
• Accountant contact details
• Evidence of business debts and commitments

Some self-employed applicants may also explore specialist home loan options where standard payslips or traditional income documents are not available.

Credit File Clean-Up Before You Apply

Your credit file can affect your home loan application before a lender even looks closely at the property. A strong income and deposit may not be enough if your credit report shows unpaid defaults, repeated missed repayments, unknown enquiries or incorrect information.

Checking your credit file before applying gives you time to identify and fix issues. In Australia, consumers can access their credit report for free once every three months. Credit reporting bodies may hold different information, so it can be useful to check more than one report before lodging a formal home loan application.

What to Check on Your Credit Report

When reviewing your credit report, look for:

• Incorrect personal details
• Credit accounts you do not recognise
• Credit enquiries you did not authorise
• Defaults or overdue accounts
• Late repayment history
• Duplicate listings
• Closed accounts still showing as active
• Incorrect credit limits
• Court judgments or insolvency information
• Signs of identity theft or fraud

Documents That May Help Fix Credit Report Errors

• Payment receipts
• Account closure letters
• Bank statements
• Email correspondence with the credit provider
• Identification documents
• Dispute reference numbers

Do not ignore small errors. Even an incorrect limit, old account or wrongly recorded missed payment can create unnecessary problems during assessment.

Reduce Unnecessary Credit Enquiries

Every credit application may leave an enquiry on your credit file. Multiple recent enquiries can raise questions, especially if they relate to personal loans, credit cards, car finance, store finance or short-term borrowing.

Before applying for a home loan, avoid unnecessary credit applications. If you are comparing options, speak with a mortgage specialist before lodging multiple applications. A good strategy can help protect your credit file and reduce avoidable assessment issues.

Maintain Strong Repayment Conduct

In the months before applying, make every repayment on time. This includes credit cards, personal loans, car loans, buy now pay later accounts, existing mortgage repayments and other regular commitments.

Set up reminders or direct debits where appropriate. A single missed repayment close to application time can create extra questions and may affect the lender’s confidence.

How to Boost Your Borrowing Power Before Applying

If your goal is to borrow more for a home loan, the most effective approach is to strengthen the areas lenders assess. You do not need to guess. You need to prepare.

Borrowing Power Improvement Checklist

1. Review all credit card limits and reduce or close unused facilities where appropriate.
2. Check whether personal loans, car loans or other debts are limiting your capacity.
3. Avoid taking on new debt before applying.
4. Complete a three-month household budget audit.
5. Reduce discretionary spending and keep bank statements clean.
6. Build or protect genuine savings.
7. Gather payslips, income statements, tax returns and evidence of variable income.
8. Document overtime, bonuses, allowances and secondary income clearly.
9. Check your credit report and correct errors before applying.
10. Speak with a mortgage specialist before submitting a formal application.

The goal is not simply to get the largest possible loan. The goal is to understand what you can comfortably afford, choose the right loan structure and submit a strong application that matches lender requirements.
