Home loans in Australia can help borrowers buy a property sooner than they could by saving the full purchase price upfront. In exchange, the borrower repays the lender over time, with interest and fees applying according to the loan contract.
For first home buyers and existing borrowers reviewing their options, the challenge is often not knowing how the pieces fit together. Deposit size, borrowing capacity, loan-to-value ratio, repayments, fixed and variable rates, offset accounts, redraw facilities and settlement costs can all affect the total cost and flexibility of a home loan.
This guide explains how home loans work in general terms, what borrowers are commonly assessed on and which loan features and costs are worth understanding before applying. It is general information only and does not take your personal objectives, financial situation or needs into account.
What is a home loan?
A home loan, also called a mortgage, is a loan secured against residential property. The lender provides funds to help purchase, refinance or sometimes build a home, and the property is used as security for the loan. If the borrower does not meet their repayment obligations, the lender may have rights under the loan agreement and mortgage security.
Most home loans are repaid over a long term, often many years. The borrower usually makes regular repayments that cover interest and, in most cases, gradually reduce the amount borrowed. The exact term, repayment type, interest rate and features depend on the lender, loan product, property, borrower profile and approval criteria.
How deposits and loan-to-value ratio work
Your deposit is the amount you contribute towards the property purchase from your own funds or other acceptable sources. It is separate from many upfront purchase costs, so borrowers usually need to allow for more than the deposit alone.
A related concept is the loan-to-value ratio, commonly shortened to LVR. LVR compares the loan amount with the lender's assessed value of the property. For example, a smaller deposit generally means a higher LVR, while a larger deposit generally means a lower LVR.
LVR matters because it can affect lender choice, pricing, eligibility, mortgage insurance requirements and risk assessment. A lender may use its own valuation of the property, which may not always match the purchase price or a buyer's expectations.
Lender's mortgage insurance
Lender's mortgage insurance, often called LMI, may apply when the loan represents a higher proportion of the property value. LMI generally protects the lender, not the borrower, if the borrower defaults and the lender suffers a loss after enforcing the security.
The cost and availability of LMI depend on lender policy, insurer criteria, property type, loan amount, borrower profile and other factors. Some borrowers may choose to save a larger deposit to reduce the likelihood or cost of LMI, while others may decide that entering the market sooner is more important. The right trade-off depends on individual circumstances.

Borrowing capacity: how lenders assess affordability
Borrowing capacity is an estimate of how much a lender may be prepared to lend based on your financial position and the lender's assessment criteria. It is not simply based on income. Lenders typically consider a broad range of factors before deciding whether to approve a home loan and on what terms.
Common assessment factors may include:
- Income: salary, wages, self-employed income, overtime, bonuses, rental income or other acceptable income sources.
- Employment or business stability: how long you have been in your role, industry or business, and how predictable your income appears.
- Existing debts: personal loans, car loans, credit cards, buy now pay later facilities, business debts and other commitments.
- Living expenses: everyday household spending, dependants, insurance, utilities, transport, education and other recurring costs.
- Credit history: repayment conduct, defaults, hardship arrangements, credit enquiries and overall credit profile.
- Deposit and savings history: the amount contributed and, in some cases, evidence of genuine savings.
- Property details: location, type, size, condition, zoning and valuation outcome.
- Interest rate buffers: lenders may assess whether repayments would still be manageable if rates were higher than the current advertised rate.
Because each lender applies its own criteria, borrowing capacity can vary between providers. A higher borrowing estimate does not necessarily mean a loan is suitable or comfortable. Borrowers should also consider their own budget, lifestyle, emergency savings and future plans.
Principal and interest versus interest-only repayments
Many home loans are repaid using principal and interest repayments. This means each repayment covers interest and also reduces the original loan balance. Over time, the loan balance generally falls if repayments are made as required.
Some loans offer an interest-only period, where repayments cover interest but do not reduce the principal during that period. This can reduce repayments in the short term, but it may increase the total interest paid over the life of the loan and can lead to higher repayments later when principal and interest repayments begin.
Interest-only lending is not automatically better or worse. It may be used by some investors or borrowers with specific cash flow reasons, but lenders assess it carefully. Owner-occupiers should understand the longer-term cost and repayment impact before choosing this structure.
Fixed vs variable home loans in Australia
One of the biggest choices borrowers face is whether to choose a fixed rate, variable rate or split loan. The interest rate type affects repayment certainty, flexibility and how quickly the loan responds to market or lender rate changes.
| Loan type | How it generally works | Potential advantages | Potential limitations |
|---|---|---|---|
| Variable rate | The interest rate can move up or down during the loan term. | May offer more flexibility, such as extra repayments, redraw or offset features, depending on the product. | Repayments can increase if the lender raises the rate. |
| Fixed rate | The interest rate is locked for an agreed fixed period. | Repayments are more predictable during the fixed period. | May have limits on extra repayments, fewer features and potential break costs if changed early. |
| Split loan | Part of the loan is fixed and part is variable. | Can provide a mix of repayment certainty and flexibility. | Requires managing two loan portions with different rules and rates. |
A fixed vs variable home loan decision is not just a rate decision. It is also about how much certainty you want, whether you plan to make extra repayments, whether you may sell or refinance, and whether features such as an offset account matter to you.
Offset accounts and redraw facilities explained
Home loan features can affect how much interest you pay and how easily you can access surplus funds. Two common features are offset accounts and redraw facilities. They sound similar, but they work differently.
Offset account
An offset account is a transaction or savings account linked to a home loan. The balance in the offset account is used to reduce the loan balance on which interest is calculated. For example, if a borrower has funds sitting in a full offset account, interest may be calculated on the loan balance minus the offset balance, subject to the lender's terms.
Offset accounts can be useful for borrowers who want to keep savings accessible while reducing interest. However, not all offset accounts operate the same way. Some may be full offset accounts, while others may be partial offset accounts. Fees, eligibility and account conditions can also differ.
Redraw facility
A redraw facility may allow a borrower to access extra repayments they have made above the required minimum repayment. This can provide flexibility if circumstances change, but redraw access is subject to lender rules. Some lenders may set minimum redraw amounts, processing times, fees or restrictions.
Redraw is not the same as having money in a separate savings account. Extra repayments usually reduce the loan balance, and access depends on the loan contract and lender systems. Borrowers should check how redraw works before relying on it for emergency funds.
Other home loan features to compare
Beyond rate type, offset and redraw, borrowers may want to compare features such as:
- Extra repayment options: whether you can pay more than the minimum and whether limits apply.
- Repayment frequency: weekly, fortnightly or monthly options, depending on lender availability.
- Package loans: bundled products that may include a home loan, offset account, credit card or other banking services, often with an annual package fee.
- Loan portability: the ability, subject to lender approval, to transfer the loan security to another property instead of applying for a new loan.
- Top-up or additional lending: the ability to borrow more against equity, subject to assessment and suitability.
- Construction loan structure: for building, funds may be released progressively as construction milestones are met.
Features can be valuable, but they may come with higher fees or rates. A loan with more features is not automatically more suitable than a simpler loan. The key is whether you will actually use the feature and whether the overall cost makes sense.
Repayments and the true cost of a home loan
Home loan repayments are influenced by the loan amount, interest rate, loan term, repayment type and repayment frequency. A longer loan term may reduce regular repayments, but it can increase the total interest paid over time. A shorter term may reduce total interest, but repayments may be higher.
Borrowers often focus on the advertised interest rate, but the total cost also includes fees, charges and how the loan is structured. A comparison rate can help show the effect of certain fees and charges for a standard loan scenario, but it may not reflect every borrower's exact situation or every possible cost.
Before applying, it can be useful to test repayment scenarios using loan calculators. Calculators can help you estimate repayments and compare broad scenarios, but they are only guides. They do not replace a lender's assessment or personal financial advice.
Upfront and ongoing costs to allow for
Buying property usually involves costs beyond the deposit. The exact costs vary by state or territory, lender, property and transaction type, but borrowers should commonly consider:
- Stamp duty and government charges: these can vary depending on the property, location and buyer circumstances.
- Conveyancing or legal fees: for reviewing contracts, handling settlement and advising on legal aspects of the purchase.
- Building, pest or strata reports: depending on property type and buyer preference.
- Loan application, valuation or settlement fees: charged by some lenders or third parties.
- Lender's mortgage insurance: if applicable based on the LVR and lender requirements.
- Registration and transfer fees: for recording changes to property ownership and mortgage interests.
- Ongoing loan fees: such as annual package fees, account fees or administration charges.
- Insurance and property costs: building insurance, council rates, strata levies, repairs and maintenance.
- Break, discharge or switching costs: if refinancing, paying out a fixed loan early or closing the loan.
First home buyer concessions or grants may be available in some circumstances, but rules vary and can change. Borrowers should check current eligibility directly with relevant state, territory or government sources and consider professional advice where needed.
How the home loan application process usually works
The home loan process can vary between lenders, but it commonly involves several stages.
- Preparation: You review your budget, savings, credit position, income documents and likely purchase costs.
- Initial borrowing estimate: A lender or broker may estimate borrowing capacity based on the information provided.
- Pre-approval: Some borrowers seek conditional approval before making an offer. Pre-approval is not final approval and may depend on the property, valuation, updated information and lender conditions.
- Property selection and contract: Once a property is chosen, the lender assesses the security and transaction details.
- Formal approval: The lender completes its assessment and may issue loan documents if approved.
- Loan documents and settlement preparation: The borrower reviews and signs documents, insurance may need to be arranged, and the conveyancer or solicitor coordinates settlement.
- Settlement: Funds are transferred, the property title is updated and the loan begins.
- Ongoing repayments: The borrower manages repayments, features, statements and future review decisions.
Timeframes depend on lender workload, document quality, valuation outcomes, contract conditions and the complexity of the borrower's situation. Providing accurate documents early can help reduce avoidable delays, but approval and timing are never assured.
Documents borrowers may need
Documentation requirements vary, but lenders commonly request evidence such as:
- identification documents;
- recent payslips or employment income evidence;
- tax returns, financial statements or business records for self-employed borrowers;
- bank statements showing income, expenses and savings;
- details of existing debts and credit limits;
- evidence of deposit funds;
- the contract of sale for the property; and
- information about other assets, liabilities or income sources.
Self-employed borrowers, investors, contractors and borrowers with complex income may need to provide additional information. Different lenders may treat income types differently, so it can help to understand the documentation expectations before applying.
Using a broker or applying directly
Borrowers can apply directly with a lender or work with a broker. A broker may help compare loan options from the lenders they have access to, explain documentation requirements and assist with the application process. However, broker access, recommendations, fees and lender panels can vary, so borrowers should understand how the broker is paid and what services are provided.
If you want help understanding lender requirements or comparing options, you can learn more about licensed broker support. Any loan option still depends on lender approval, credit assessment, property details and individual circumstances.
Questions to ask before choosing a home loan
Before committing to a home loan, consider asking:
- What is the interest rate, and is it fixed, variable or split?
- What is the comparison rate, and which fees are included or excluded?
- What will my repayments be if rates rise?
- Can I make extra repayments, and are there limits or fees?
- Is there an offset account, and is it full or partial offset?
- How does redraw work, and are there restrictions?
- Will lender's mortgage insurance apply?
- What upfront and ongoing fees apply?
- What happens if I sell, refinance or repay the loan early?
- How much emergency cash should I keep outside the purchase?
- Does this loan leave enough room for lifestyle costs, maintenance and unexpected expenses?
Key takeaways
A home loan is a long-term financial commitment, and the right structure depends on more than the headline interest rate. Deposits, LVR, borrowing capacity, repayment type, fees, offset accounts, redraw access and settlement costs can all influence how affordable and flexible the loan is.
For borrowers in Australia, the most useful starting point is to understand your own budget, compare realistic repayment scenarios and ask clear questions about loan features and costs. Lender approval, pricing and loan availability depend on individual circumstances, property details and provider criteria.
