Most people compare home loans by scanning rate tables and picking the lowest number.
That approach works if every loan had identical features, no ongoing fees, and you never needed to change anything for 30 years. In reality, a rate that looks sharp at settlement can become expensive the moment your circumstances shift or you need access to a feature the product doesn't support. The question is not which loan has the lowest advertised rate today. It is which loan structure supports your income, your deposit, and the way you'll actually use the property over the next few years.
Why Advertised Rates and Your Actual Rate Are Different
The rate you see advertised assumes maximum discounts applied. Most lenders publish their lowest possible rate based on a specific loan amount, a specific LVR, and sometimes a specific employment type or deposit source. If your situation sits outside those parameters, the rate you're offered will be higher.
Consider a buyer in Kew purchasing an owner-occupied property with a 15% deposit. The advertised variable rate might be 5.89%, but that rate assumes an 80% LVR and may exclude LMI scenarios. Once LMI is added and the LVR adjusts, the actual rate offered could be 6.14% or higher depending on the lender's pricing model. Rate comparison without knowing your assessed LVR is guesswork.
Fixed Rate, Variable Rate, or Split: What Each One Actually Does
A fixed rate locks your repayments for a set term, usually between one and five years. You know exactly what you'll pay, but you also lose access to offset accounts in most cases and face break costs if you repay early or refinance before the term ends.
A variable rate moves with the lender's pricing decisions, which are influenced by the Reserve Bank cash rate, funding costs, and competitive pressures. Variable loans typically include offset accounts and allow unlimited extra repayments without penalty.
A split loan divides your balance between fixed and variable portions. You get partial rate certainty and partial flexibility. In our experience, buyers who expect income growth or plan to make lump sum repayments within three years tend to favour a higher variable portion. Those prioritising budget certainty in the short term lean toward a higher fixed portion.

Offset Accounts and How They Change the Real Cost of Your Loan
An offset account sits alongside your home loan and reduces the interest charged each day based on the balance sitting in the account. If you have a $600,000 loan and $40,000 in your offset, you're only charged interest on $560,000.
The value of an offset depends entirely on how much you keep in it. If your balance rarely exceeds $5,000, the interest saving will be minimal and may not justify paying a higher rate for the feature. If you regularly hold $30,000 or more, the offset can save thousands of dollars in interest each year and shorten your loan term without formally increasing repayments.
Not all offset accounts are structured the same way. Some lenders offer 100% offset on variable loans only. Others allow partial offset on fixed portions or cap the number of offset accounts per loan. If you're comparing two loans and one has a rate 0.15% lower but no offset, run the numbers with your actual savings balance before deciding. The higher rate with full offset often works out cheaper over 12 months.
Application Fees, Ongoing Fees, and Package Discounts
Most lenders charge an application fee, sometimes called an establishment fee, ranging from $0 to $995. Some waive it during promotional periods. Some charge it but refund it at settlement if you take out other products like insurance.
Ongoing fees include monthly account-keeping fees, annual package fees, and offset account fees. A loan with no ongoing fees and a rate of 6.19% can be cheaper over five years than a loan at 5.99% with a $395 annual package fee, depending on your loan amount.
Package discounts bundle your home loan with a transaction account or credit card and reduce your interest rate by 0.10% to 0.30%. The discount applies as long as you hold the package, but the package itself usually costs $300 to $400 per year. Calculate whether the rate discount outweighs the annual fee before committing.
Loan Features That Matter When Your Situation Changes
Portability lets you transfer your loan to a new property without refinancing. If you're likely to upgrade or move within five years, portability avoids discharge fees, application fees, and the risk of requalifying at a higher rate or under tighter serviceability rules.
Redraw allows you to access extra repayments you've made above the minimum. Some lenders process redraw requests instantly online. Others require a phone call and three days' notice. Some cap the number of free redraws per year or charge a fee after the first few.
Extra repayment flexibility matters if your income is variable or you receive bonuses. Some fixed loans allow up to $30,000 in additional repayments per year without penalty. Others allow none. If you're self-employed or work in a role with performance-based income, a loan that restricts extra repayments can become a problem quickly.
How Lender Serviceability Policy Affects Your Borrowing Capacity
Two lenders can offer the same rate but approve different loan amounts for the same applicant. Serviceability is assessed using your income, your living expenses, and a buffer rate set by the lender, usually 3.0 percentage points above the loan rate.
Some lenders apply conservative expense estimates. Others allow you to declare actual living costs if they're below the benchmark. Some lenders assess rental income at 80% of the lease amount. Others accept 100% if the lease is long-term and independently verified. These differences can change your maximum loan amount by $50,000 or more.
If you're comparing loan products and one lender offers a lower rate but approves a smaller loan amount, the lower rate becomes irrelevant. Borrowing capacity and interest rate need to be assessed together, not in isolation. We regularly see this with clients in Kew purchasing near the top of their budget.
Owner-Occupied Versus Investment Loan Structures
Owner-occupied home loans are priced lower than investment loans, usually by 0.20% to 0.50%. The gap exists because owner-occupied loans are considered lower risk under APRA's prudential framework.
If you're buying in Kew and plan to live in the property for two years before converting it to an investment, the loan starts as owner-occupied. When it switches to investment, the rate will increase in line with the lender's investment loan pricing. Some lenders allow you to keep the existing loan and vary the purpose. Others require you to refinance into a new product.
If you're considering this strategy, check whether the lender allows purpose changes on the existing facility or whether a refinance will be required. A refinance means another application, another valuation, and another credit check. Knowing this at the start helps you choose a lender with flexible purpose-change terms.
Comparing Loans Without Getting Distracted by Every Feature
A loan comparison becomes unmanageable when you try to weigh every feature equally. Most buyers don't need every feature, and paying for unused flexibility costs money over time.
Start by identifying the three features that matter for your situation. If you hold savings and expect to build that balance over time, prioritise a full offset. If your income is variable or you receive annual bonuses, prioritise unlimited extra repayments and instant redraw. If you plan to move within five years, prioritise portability and low exit fees.
Once you've shortlisted loans that include those features, compare the real cost over 12 months using your actual numbers: your loan amount, your likely offset balance, and any fees. That gives you a dollar figure you can compare directly. Advertised rates are a starting point. Actual cost over 12 months, based on how you'll use the loan, is the number that matters.

Frequently Asked Questions
Why is the rate I'm offered different to the advertised rate?
Advertised rates assume maximum discounts applied, usually at 80% LVR with a specific loan amount and employment type. If your deposit, income structure, or loan amount sits outside those parameters, the rate you're offered will be higher. LMI, loan size, and whether the property is owner-occupied or investment also affect your actual rate.
Is a fixed rate or variable rate loan better for me?
A fixed rate locks your repayments for one to five years and suits buyers prioritising budget certainty, but you lose access to offset accounts and face break costs if you repay early. A variable rate moves with lender pricing, includes offset access, and allows unlimited extra repayments without penalty. A split loan gives you partial certainty and partial flexibility.
How much does an offset account actually save?
An offset account reduces the interest charged based on the balance sitting in the account. If you hold $30,000 or more consistently, the interest saving can reach thousands of dollars per year. If your balance rarely exceeds $5,000, the saving is minimal and may not justify paying a higher rate for the feature.
Can I compare home loans just by looking at interest rates?
Advertised rates are a starting point, but they don't reflect ongoing fees, package costs, or how the loan's features suit your situation. A loan with a lower rate but no offset or high annual fees can cost more over 12 months than a slightly higher rate with full offset and no package fee.
What loan features matter if I plan to move or upgrade in a few years?
Portability lets you transfer your loan to a new property without refinancing, avoiding discharge fees and reapplication. Low or no exit fees and flexible redraw terms also matter if your situation is likely to change. Check whether the lender allows purpose changes if you plan to convert an owner-occupied loan to investment.
