Most lenders want you to compare one number: the interest rate. That's deliberate, because it keeps you from looking at what the loan actually costs you or whether you can use it the way you need to.
Comparing home loans properly means looking at the structure, the fees, the features you'll use, and how the loan behaves when your circumstances change. A rate that looks low on paper can cost you more if the loan doesn't let you pay it down early or charges you to leave. The goal is to find the loan that gives you control, not the one that sounds good in a headline.
Interest rates matter, but only with context
The advertised rate is usually not the rate you'll get. Lenders publish their lowest possible rate to attract attention, then apply discounts based on your deposit size, whether you're an owner-occupier or investor, and whether you're willing to take on a package with fees attached.
Consider a buyer refinancing with a 20% deposit on an owner-occupied property. One lender offers a variable rate 0.15% lower than another, but charges a $395 annual package fee and doesn't offer an offset account without upgrading to a premium product. The second lender has a slightly higher rate but includes a full offset account at no extra cost and no annual fee. Over the life of the loan, the second option saves money because the offset reduces the interest charged each month, and there's no ongoing fee eating into the benefit.
Rate discounts also expire. A lender might offer a honeymoon rate for the first year, then revert to a higher standard variable rate. If you're comparing loans, check what the rate becomes after any introductory period ends, and whether the lender has a history of passing on rate cuts from the Reserve Bank. Some lenders are faster to raise rates than they are to drop them.
The offset account is the most underrated feature
An offset account sits alongside your home loan and reduces the interest you're charged by the amount you keep in the account. If you have a $500,000 loan and $20,000 in your offset, you only pay interest on $480,000. It's not a redraw facility. The money stays accessible, and you're not asking the lender for permission to use your own cash.
Not all offset accounts work the same way. Some lenders offer a partial offset, which only reduces your interest by a percentage of the balance. Others charge a monthly fee for the offset feature. A full offset with no additional fees is the version worth having, and it's common enough that you shouldn't settle for less unless there's a strong reason.

In our experience, buyers who use an offset account consistently pay their loan down faster than those relying on redraw, because the money is visible and accessible. That makes it easier to keep a buffer without losing the interest saving. If you're comparing home loan options, make sure the offset is included in the package, not sold as an add-on.
Fixed, variable, or split: match the structure to your situation
A variable rate moves with the market. You benefit when rates drop, and you're exposed when they rise. A fixed rate locks in your repayment amount for a set period, usually between one and five years. A split loan gives you both: part of the loan is fixed, part is variable.
The question isn't which structure is better. It's which one fits what you're trying to do. If you need certainty because your income is irregular or your budget is tight, fixing part or all of your loan removes the risk of repayment increases. If you want to pay extra or access features like an offset, a variable loan gives you flexibility without penalty.
Fixed loans typically don't allow extra repayments beyond a small annual cap, often around $10,000 to $30,000 depending on the lender. If you pay more than that, or if you refinance or sell before the fixed term ends, you'll be charged break costs. Those costs can be substantial if rates have dropped since you fixed, because the lender loses the interest they expected to earn. A split loan lets you fix part of the loan for certainty and keep part variable so you can make extra repayments or use an offset without restriction.
Fees add up faster than you think
Application fees, valuation fees, settlement fees, annual package fees, and discharge fees all reduce what the loan is actually worth to you. Some lenders waive the application fee as a promotion. Others bundle features into a package and charge $300 to $400 per year for access.
A loan with a rate 0.10% higher but no annual fee can cost less over time than a loan with a lower rate and a $395 yearly package fee, especially on smaller loan amounts. If you're comparing two loans, calculate what the fee costs you annually, then compare that to the rate difference. On a $400,000 loan, a 0.10% rate difference equals around $400 per year in interest. If one loan charges a $395 annual fee, the rate advantage disappears.
Valuation and settlement fees are often non-negotiable, but some lenders cover them as part of a refinancing offer. Discharge fees apply when you pay out the loan or switch lenders, and they typically range from $150 to $400. If you're planning to refinance in a few years or sell the property, factor the discharge fee into the total cost.
Loan features you'll actually use
Lenders promote features that sound useful but don't always match how people use their loans. A redraw facility lets you withdraw extra repayments you've made, but some lenders charge a fee for each withdrawal or set a minimum redraw amount. Others restrict access during certain periods or slow down the approval process.
A portability feature lets you move your loan to a new property without refinancing. That can save you time and money if you're upgrading or relocating, but not all lenders offer it, and some charge a fee to transfer the loan. If you're likely to move within a few years, it's worth checking whether the loan is portable and what the process involves.
Extra repayment options matter if you're planning to pay the loan down faster. Some lenders allow unlimited extra repayments on a variable loan with no penalty. Others cap the amount or charge a fee if you exceed a set limit. If you're expecting irregular income or plan to put bonuses or tax returns towards the loan, make sure the loan structure supports it.
How to compare without getting lost in the detail
Start with what you need the loan to do. If you want to pay it down quickly, prioritise loans that allow unlimited extra repayments and include an offset account. If you need stable repayments, look at fixed or split options and compare the break cost terms. If you're refinancing, calculate how long it will take to recover the upfront costs based on the rate and fee difference.
Use a comparison that includes the interest rate, the comparison rate, and the fees. The comparison rate is meant to reflect the true cost of the loan by including some fees, but it doesn't account for how you'll use the loan or whether you'll keep it for the full 30-year term. It's a starting point, not the whole picture.
Don't compare loans in isolation. A loan that works well for someone with a 20% deposit and steady income might not suit someone with a 10% deposit using a guarantor. The same applies to investors versus owner-occupiers. Lenders price these scenarios differently, and the features available change depending on the loan type. If you're an investor, check whether the loan allows interest-only repayments and how long that period lasts. If you're a first home buyer, check whether the lender offers a discount for low-deposit loans or charges higher rates once Lenders Mortgage Insurance is involved.
The lender's reputation matters when things go wrong
A loan isn't just a rate and a contract. It's a relationship with a lender that will last years, and how they treat you during that time affects whether the loan works for you. Some lenders are difficult to deal with when you need to make changes, increase your loan, or request a rate review. Others are responsive and willing to negotiate.
We regularly see clients stuck with lenders who won't budge on rates, even when the client has paid on time for years and built significant equity. Moving to a lender with a lower rate and a better servicing approach often saves thousands, not just in interest but in time and frustration. If you're comparing lenders, look at how they've handled rate changes in the past and whether they have a reputation for keeping existing customers competitive, not just new ones.
When to get help comparing loans
If you're comparing two or three loans and the difference is clear, you can make the call yourself. If you're looking at ten lenders, each with multiple products, different fee structures, and varying eligibility criteria, the process gets complicated quickly. A broker has access to loan details that aren't always published online, and can tell you which lenders are likely to approve your application based on your income, deposit, and credit history.
That's particularly useful if your situation isn't straightforward. Self-employed applicants, contractors, buyers using gifted deposits, and anyone with a complex income structure will find that some lenders assess applications more favourably than others. Choosing the wrong lender can mean a declined application or a lower borrowing capacity, even if your financial position is solid.

Frequently Asked Questions
What's the difference between the interest rate and the comparison rate?
The interest rate is what the lender charges on the loan amount. The comparison rate includes some fees to show the true cost, but it assumes you'll keep the loan for 30 years and borrow a standard amount. It's useful for comparing loans, but it doesn't reflect how you'll actually use the loan or whether you'll refinance or sell earlier.
Should I fix or stay variable when comparing home loans?
It depends on whether you value certainty or flexibility. A fixed rate locks in your repayments but limits extra payments and charges break costs if you leave early. A variable rate lets you pay extra and use an offset, but your repayments can increase if rates rise. A split loan gives you both.
How much do loan fees actually cost over time?
An annual package fee of $395 costs you the same as a 0.10% higher interest rate on a $400,000 loan. Upfront fees like application and valuation can add $1,000 to $2,000 to the cost of switching loans. Always calculate the total fee cost over the time you plan to keep the loan, not just the first year.
Is an offset account worth it when comparing loans?
Yes, if it's a full offset with no extra fees. An offset reduces the interest you pay by the amount you keep in the account, and the money stays accessible without needing lender approval. It's more flexible than redraw and helps you pay the loan down faster without losing access to your cash.
How do I know if a lender will actually give me the rate they advertise?
Advertised rates are usually the lowest rate available, which often requires a large deposit, a premium package, or specific loan features. The rate you're offered depends on your deposit size, whether you're an owner-occupier or investor, and the loan amount. A broker can tell you what rate you'll actually get before you apply.
