1. Compare The Interest Rate And Total Loan Cost
The interest rate affects your repayments, but it does not tell the whole story. Two lenders can offer different rates, fees and conditions for similar borrowing amounts.
Start by comparing the interest rate, comparison rate and total costs over the period you expect to keep the loan.
Interest Rate Versus Comparison Rate
The advertised interest rate determines the interest charged on your outstanding balance. However, fees and loan conditions can change the overall value of an offer.
The comparison rate combines the interest rate with certain fees and charges into one annual percentage. It helps you compare similar loans on a more consistent basis.
However, comparison rates use standard assumptions and may exclude some costs. They also cannot measure the personal value of features such as offset accounts.
For example, consider two loans for an $800,000 property purchase. One has a lower advertised rate but higher fees, while another charges more interest but offers useful savings features.
The second loan could suit you better if its features save more than its additional costs. You should calculate the likely outcome using your expected savings and repayment behaviour.
Fees To Compare
- Application and establishment fees: These are upfront charges that increase the initial cost of arranging your mortgage.
- Ongoing account fees: Monthly or annual charges can gradually reduce the value of a loan with otherwise attractive terms.
- Package fees: Some lenders charge an annual fee for bundled benefits, which may include an offset account or discounted pricing.
- Discharge fees: These charges may apply when you repay or close your loan, including during a refinance.
- Break costs: A fixed-rate loan may incur significant costs if you exit early or make certain changes.
2. Offset Account Versus Redraw Facility
An offset account and a redraw facility can both reduce interest costs. However, they differ in how you hold your money and access it later.
Your choice matters if you maintain savings, expect large expenses or plan to turn your home into an investment property.
How An Offset Account Works
An offset account is a transaction account linked to your mortgage. Its balance reduces the loan amount used to calculate interest.
Suppose your mortgage balance is $720,000 and your offset holds $50,000. You generally pay interest on $670,000 instead.
You retain access to your offset savings for bills, emergencies and other expenses. Meanwhile, your eligible balance continues reducing the interest calculated on your mortgage.
However, offset accounts can carry higher rates or additional fees. They offer the greatest potential value when you maintain meaningful savings consistently.

How A Redraw Facility Works
A redraw facility allows you to withdraw eligible extra repayments you’ve made above the required amount. The lender’s rules determine your access, limits and any associated fees.
For example, you might make extra repayments while working overtime. Later, you could redraw some funds for renovations, subject to your loan conditions.
However, access may be restricted or delayed. Fixed-rate loans can also limit additional repayments, so check the relevant conditions before committing.
Which Feature Offers Better Value?
| Feature | Offset Account | Redraw Facility |
| How It Works | Savings reduce the balance used to calculate interest. | Extra repayments reduce the outstanding loan balance. |
| Access To Money | Usually available through normal banking transactions. | Depends on the lender’s redraw rules. |
| Account Structure | Separate transaction account linked to the mortgage. | Additional repayments remain within the loan. |
| Potential Costs | May involve package fees or a higher rate. | May involve redraw fees or withdrawal restrictions. |
| Future Investment Use | Can preserve flexibility over the original loan balance. | Redrawing for private expenses can complicate tax deductions. |
Neither feature automatically wins. Compare the costs, access conditions and your plans before deciding.
3. Investment Conversion: Planning For A Future Rental Property
Your home may eventually become a rental property when you relocate, upgrade or move interstate. Therefore, today’s loan structure can affect your future financial flexibility.
An important consideration is how an offset account preserves access to savings without reducing the original mortgage balance.
Why The Original Loan Balance Matters
Australian tax rules generally link interest deductibility to how borrowed funds are used. Interest on debt used to acquire an income-producing rental property may be deductible, subject to the relevant conditions.
However, interest on private borrowing generally isn’t deductible simply because a rental property secures the loan.
Consider a property originally purchased as your home. You keep the property when you move elsewhere, then rent it to tenants.
If you previously placed savings into an offset account, those savings reduced interest without directly paying down the loan principal. The original debt therefore remains available, although its tax treatment depends on the circumstances.
By contrast, making extra repayments reduces the loan balance. Redrawing those repayments later for private expenses can create a mixed-purpose loan.
The Australian Taxation Office explains that interest must be apportioned when borrowed funds serve both income-producing and private purposes. Accurate records become especially important when redraw transactions occur.
Example: Offset Versus Extra Repayments
Suppose your original home loan balance is $600,000. You accumulate $80,000 in savings while living in the property.
- With an offset account: Your loan remains $600,000, while the offset reduces the balance used to calculate interest to $520,000.
- With extra repayments: Your outstanding loan falls to $520,000, and the additional $80,000 may become available through redraw.
- After converting to a rental: Withdrawing money from redraw for private spending can complicate interest deductibility, whereas accessing separate offset savings does not itself create a new borrowing.
These examples illustrate the different loan structures, not a guaranteed tax outcome. The deductibility of interest depends on the actual use of borrowed funds and other applicable rules.
If you may convert your home into a rental, consider an offset account and seek tax advice before changing your loan structure. Do not assume that all interest becomes deductible when tenants move in.

4. Fixed, Variable Or Split Home Loan?
Your interest rate structure determines how your repayments respond to changing rates. It also affects your ability to make extra repayments and access certain features.
Variable Rate Home Loans
A variable-rate mortgage can move when your lender changes its pricing. Your repayments or the time needed to repay the loan may change accordingly.
Variable loans often provide greater flexibility, although features vary between lenders.
- Offset compatibility: Many variable loans support offset accounts, making them useful for borrowers who maintain savings.
- Extra repayments: Some allow unlimited additional repayments without the restrictions associated with certain fixed-rate products.
- Rate uncertainty: Your repayments may increase if your lender raises your rate, so maintain room in your budget.
The RBA cash rate influences funding conditions and monetary policy across the economy. However, lenders do not necessarily change every mortgage rate by the same amount.

Fixed Rate Home Loans
A fixed-rate mortgage keeps your interest rate unchanged for an agreed period, commonly between one and five years. This provides repayment certainty during that period.
However, fixed loans can restrict extra repayments, offset access and refinancing flexibility.
Check what happens when your fixed period ends. Your loan may move to a variable rate unless you arrange another option.
Split Home Loan
A split home loan divides your borrowing between fixed and variable portions. This structure combines some repayment certainty with access to selected variable-rate features.
For example, you could fix part of your loan while keeping the remainder variable. Your lender’s conditions determine which portion supports an offset account or additional repayments.
| Loan Structure | Main Advantage | Main Limitation |
| Variable | Greater flexibility with many products. | Repayments can change. |
| Fixed | Greater certainty during the fixed period. | Restrictions and break costs may apply. |
| Split | Combines fixed and variable features. | More conditions and potentially separate fees. |
5. Repayment Frequency And Extra Repayments
Your repayment schedule affects how your income flows into the mortgage. The right arrangement can also help you manage expenses and reduce interest over time.
Monthly Versus Fortnightly Repayments
Monthly repayments suit borrowers who receive a monthly salary. Fortnightly repayments may suit people paid every two weeks.
However, check how your lender calculates the amount. Paying half your monthly repayment every fortnight produces 26 half-payments annually.
That equals 13 monthly repayments rather than 12, potentially helping you reduce your balance faster. Your actual savings depend on the loan terms, interest rate and payment arrangements.
Extra Repayment Flexibility
Look for a loan that allows additional repayments without unnecessary charges. This feature becomes particularly valuable when you receive bonuses, commissions or other irregular income.
However, fixed-rate products may impose extra repayment limits. Exceeding those limits could trigger fees or break costs.
Before choosing, establish whether you can make lump-sum payments, change your repayment frequency and access eligible extra repayments later.

6. Loan Portability And Future Flexibility
Loan portability allows you to transfer an existing home loan from one property to another, subject to lender approval and the loan conditions.
This feature may help if you sell your current home and buy another without wanting to replace your mortgage immediately.
However, portability isn’t guaranteed. Your lender may assess the new property, borrowing requirements and settlement arrangements.
For example, you might find a new property before selling your existing home. Your lender may require a bridging loan or another arrangement to manage the timing difference.
Ask whether your lender supports simultaneous settlements, substitutions of security and bridging finance. Also confirm whether portability preserves your existing rate and features.
A portable loan can provide convenience, but it shouldn’t outweigh substantially better pricing or more suitable features elsewhere.
7. Lenders Mortgage Insurance Waivers And Low-Deposit Options
A deposit below 20% can mean paying Lenders Mortgage Insurance (LMI) on a conventional home loan. LMI generally protects the lender against losses if a borrower defaults.
However, some borrowers can avoid this cost through eligible government schemes or lender-specific waivers.
Professional And Essential Worker Waivers
Certain lenders offer LMI waivers to eligible professionals. These programs can include healthcare workers, doctors and selected other occupations.
For example, Westpac publishes eligibility criteria for selected healthcare and emergency services professionals. Some eligible applicants may borrow with deposits below 20% without paying LMI.
Eligibility differs by occupation, income, deposit and lender policy.
| Borrower Type | Potential Benefit | Important Condition |
| Eligible doctors | May qualify for an LMI waiver with a smaller deposit. | Registration, loan size and lender criteria apply. |
| Eligible nurses and midwives | Some programs support deposits below 20%. | Income thresholds and employment requirements may apply. |
| Other eligible professionals | Selected lenders may offer specialised lending policies. | Occupation alone doesn’t guarantee approval. |
| Other low-deposit borrowers | Government-backed schemes may remove the LMI requirement. | Scheme eligibility and participating lender rules apply. |
Do not assume every lender covers teachers, nurses, police officers or other essential workers. Check the current eligible occupations and maximum loan-to-value ratio directly with the lender.
Government Schemes And First-Home Buyer Support
The Australian Government’s 5% Deposit Scheme (Formerly Home Guarantee Scheme) can help eligible buyers purchase a home with a smaller deposit without paying LMI. Availability and conditions depend on the relevant guarantee pathway and participating lender.
The First Home Guarantee arrangements changed from 1 October 2025. Therefore, older articles describing previous income caps or property limits may no longer reflect the current rules.
A smaller deposit can reduce the time needed to enter the property market. However, borrowing more also increases your debt and may increase repayments.
How Grants Affect Your Feature Choice
State and territory grants or stamp duty concessions can reduce your upfront costs. This may leave more money available for an emergency fund or offset account.
However, eligibility often depends on the property type, purchase price, residency and whether you meet first-home buyer requirements.
| State Or Territory | What To Check Before Choosing A Loan |
| New South Wales | Review the First Home Buyers Assistance Scheme for applicable transfer duty exemptions or concessions. |
| Victoria | Eligible buyers may receive full duty exemption up to $600,000 or reduced duty between $600,001 and $750,000. |
| Queensland | Check the current first-home owner grant and transfer duty concession rules for your property. |
| Western Australia | Review the first-home owner grant and first-home owner rate of duty, including recent threshold changes. |
| South Australia | Confirm the current grant and any applicable transfer duty relief for eligible purchases. |
| Tasmania | Check the latest grant arrangements and any available duty concessions. |
| Australian Capital Territory | Review current first-home buyer assistance and eligibility requirements. |
| Northern Territory | Check current homebuyer assistance programs and their conditions. |
These benefits are separate from mortgage features. Nevertheless, they influence how much deposit you need and how much cash remains after settlement.
Compare the combined impact of your grant, deposit, LMI position and ongoing loan costs. A low-deposit option isn’t automatically the cheapest long-term choice.
8. Principal And Interest Versus Interest-Only Repayments
Your repayment type determines whether you gradually reduce the amount borrowed or initially pay interest only.
Principal And Interest
Principal-and-interest repayments cover the interest charged and reduce your outstanding debt. Consequently, you build equity as you repay the loan, assuming other factors remain unchanged.
This structure commonly suits owner-occupiers planning to keep their homes over the longer term.
Interest-Only Repayments
Interest-only repayments cover interest during an agreed period without reducing the principal through scheduled repayments. Your debt therefore remains largely unchanged during that period.
Once the interest-only period ends, repayments generally increase because you must repay the principal over the remaining loan term.
Interest-only lending may suit particular investment strategies, but it can cost more overall. Check the interest rate, future repayments and lender conditions carefully.
9. Flexible Access, Loan Management And Digital Banking
A good mortgage should fit your daily finances rather than make ordinary banking harder. Consider how easily you can manage repayments, savings and account information.
Look for practical features that support your preferred banking habits.
- Multiple offset accounts: Some lenders let you link several accounts, which can help you organise savings for different expenses.
- Automatic repayments: Direct debits can help you make repayments on time without relying on manual transfers.
- Mobile and online banking: Convenient account access helps you monitor balances, transactions and available redraw amounts.
- Additional loan splits: Separate loan portions can help you organise borrowing for different purposes, subject to lender approval and tax considerations.
- Flexible repayment changes: The ability to adjust repayment frequency can help when your income schedule changes.
Not every lender offers these options. Check account limits, transfer restrictions and any fees before treating them as deciding factors.
10. Serviceability And Protection Against Financial Stress
A feature-rich loan can still be unsuitable if repayments leave you financially stretched. Your borrowing capacity and emergency savings deserve as much attention as your interest rate.
Banks assess whether you can afford repayments under their lending criteria. APRA confirmed in May 2026 that the mortgage serviceability buffer remains three percentage points above the loan interest rate for applicable bank assessments.
This is a lending assessment requirement, not a prediction of future interest rates. You should also test your personal budget against higher repayments.
Prioritise a loan that leaves room for unexpected expenses, insurance, maintenance and changes in income. An offset account can help preserve accessible savings while reducing interest.
Also review whether your lender offers repayment assistance during financial hardship. Contacting the lender early can help you understand available support if circumstances change.
11. How To Compare Home Loan Features Side By Side
Once you understand the main features, compare complete loan offers rather than choosing individual benefits in isolation.
The best comparison considers the cost of borrowing, flexibility and the likelihood you’ll use each feature.
For example, a buyer with $60,000 in savings may value an offset account more than a buyer who spends most of their income each month.
Similarly, someone planning to move within three years may prioritise portability and exit costs. A long-term owner might focus on extra repayments and interest savings instead.
Use the following comparison framework when reviewing lender offers.
| Comparison Factor | What To Examine |
| Interest rate | Compare the rate offered for your actual loan amount and deposit. |
| Comparison rate | Review the standardised cost measure alongside the advertised rate. |
| Offset account | Check eligibility, fees, account limits and linked-account conditions. |
| Redraw facility | Confirm access rules, fees and any restrictions on withdrawals. |
| Extra repayments | Establish whether additional payments are permitted without penalties. |
| Fixed-rate conditions | Check repayment limits, break costs and the features available during the fixed period. |
| Portability | Ask whether the lender permits security substitutions and what approval requires. |
| LMI waiver | Verify your occupation, income, deposit and loan-size eligibility. |
| Exit flexibility | Check discharge fees and the process for refinancing or selling. |
Buying a house involves more than securing approval. Your mortgage should support your financial priorities throughout ownership, including any plans to move or invest later.

Conclusion: Choose Features That Match Your Future
The answer to what features matter most in a home loan depends on how you earn, save, repay and plan to use your property.
A competitive interest rate matters, but flexibility can create value that an advertised rate cannot show. Offset accounts, redraw facilities, extra repayments and suitable loan structures can all improve your financial position.
Meanwhile, LMI waivers and government assistance may reduce your upfront costs if you qualify. However, you should compare their benefits against the full borrowing cost and the restrictions attached.
Think beyond settlement day. The right mortgage should support your current budget while leaving room for changing circumstances and future property decisions.
Ultimately, the strongest choice isn’t necessarily the loan with the most features. It’s the loan whose costs, conditions and flexibility suit your goals.
Frequently Asked Questions
1. What Features Matter Most In A Home Loan?
The most important features are competitive interest rates, reasonable fees, repayment flexibility and access to an offset account or redraw facility. Your priorities depend on your savings, income and plans for the property.
2. Is An Offset Account Better Than A Redraw Facility?
An offset account generally provides easier access to separate savings while reducing the balance used to calculate interest. A redraw facility lets you access eligible extra repayments, subject to lender conditions.
3. Is A Lower Interest Rate Always Better?
No, because fees and feature costs can outweigh a small rate advantage. Compare the comparison rate, total costs and the practical value of the features you’ll actually use.
4. What Is A Split Home Loan?
A split home loan divides your borrowing into fixed and variable portions. It can provide some repayment certainty while retaining flexibility on the variable portion.
5. Can I Avoid Lenders Mortgage Insurance With A Small Deposit?
Possibly, because eligible borrowers may qualify for government-backed schemes or lender-specific LMI waivers. Eligibility depends on the program, occupation, deposit and other lending requirements.
6. Does An Offset Account Help If I Turn My Home Into A Rental?
An offset account can preserve access to savings without reducing the original loan principal. However, tax deductions depend on the use of borrowed funds and applicable tax rules, not simply the property’s rental status.
7. What Is Loan Portability?
Loan portability allows you to transfer an existing mortgage to another property, subject to lender approval and loan conditions. It may simplify a move, but approval and settlement requirements still apply.
8. Should I Choose A Fixed Or Variable Home Loan?
A fixed rate provides greater certainty during the agreed period, while a variable rate may offer more flexibility. A split loan combines elements of both, depending on your lender’s conditions.
