If you’re planning to buy a home, one of the first questions you might ask yourself is, how much can I borrow? Understanding your borrowing power is crucial in setting realistic expectations and ensuring you’re financially prepared for homeownership.
This article explores the key factors affecting your borrowing capacity, common challenges home buyers face and helpful tips to improve your chances of securing a home loan.
Factors Influencing Borrowing Capacity
Lenders assess various factors to determine how much you can borrow and knowing these in advance can help you navigate the home loan process with confidence. These factors include:
- Income – Your income level and stability directly impact your borrowing power. Lenders consider salary, rental income, bonuses and other revenue streams to assess your ability to repay a loan.
- Credit History – Your credit score is a critical factor in the home loan approval process. A strong credit score can improve your borrowing capacity, while a poor credit history may result in higher interest rates or loan rejection.
- Existing Debts and Liabilities – Lenders assess your current financial commitments, including car loans, credit card balances and personal loans. A high debt-to-income ratio can reduce your borrowing power.
- Savings and Deposit Amount – The size of your deposit influences your borrowing capacity. A higher deposit reduces the loan-to-value ratio (LVR) and can eliminate the need for Lenders Mortgage Insurance (LMI).
- Employment Status – A stable, full-time job is favourable for loan approval, whereas self-employed individuals may need to provide additional documentation to prove financial stability.
- Age and Financial Commitments – Your age and long-term financial responsibilities, such as dependents, can impact your borrowing power. Lenders may adjust loan terms based on your expected retirement age.
- Property Details – The type and location of the property you’re purchasing can also influence how much you can borrow. Lenders may have specific criteria for high-risk or rural properties.
Common Challenges (Pain Points) in Securing a Home Loan
Securing a home loan can be a complex process, with several challenges that may impact your ability to borrow the amount you need. Here are some of them:
- High Property Prices – Rising housing prices across Australia mean buyers need larger deposits and higher loan amounts, making affordability a challenge.
- Stringent Lending Criteria – In recent years, lenders have tightened loan requirements, increasing scrutiny on income, expenses and financial behaviour.
- Impact of Existing Debts – Student loans, credit card debt and car loans can reduce borrowing capacity, affecting how much you can borrow for a home loan.
- Employment Instability – Casual, contract and self-employed workers often face additional hurdles in proving income stability to lenders.
- Age-Related Constraints – Older applicants may struggle with shorter loan terms, reducing their borrowing power.
How to Improve Your Borrowing Power

Improving your borrowing power is key to securing a better home loan deal. By making strategic financial adjustments, you can increase your chances of loan approval and access more favourable terms.
Use a Borrowing Power Calculator
Before applying for a home loan, use a borrowing power calculator to estimate how much you might be eligible to borrow based on your income, expenses and debts.
Improve Your Credit Score
Paying bills on time, reducing outstanding debts and avoiding late payments can boost your credit score and enhance your borrowing capacity.
Reduce Existing Debts
Lowering your credit card balances and paying off personal loans can improve your debt-to-income ratio, increasing your chances of loan approval.
Save for a Larger Deposit
A deposit of 20% or more can help you avoid LMI and improve your loan terms.
