How to compare home loans and find the right fit

Comparing home loans feels overwhelming when you're staring at spreadsheets full of interest rates and product names that all sound identical.

The insight that changes how you approach this: the loan with the lowest advertised rate often costs more over time once you account for fees, flexibility, and how you'll actually use the money. Your job isn't to find the cheapest rate. It's to find the loan structure that matches how you earn, spend, and plan to pay down debt.

What actually changes between loan products

Loan products differ in three areas that affect your monthly cash flow and long-term cost: the rate type, the account features, and the conditions attached to accessing those features. A variable rate loan adjusts when the Reserve Bank changes the cash rate. A fixed rate holds steady for a set period, typically one to five years. A split loan divides your borrowing between both, which can work well if you want rate certainty on part of your debt while keeping flexibility on the rest.

Consider a couple purchasing a two-bedroom apartment in Footscray for $580,000 with a 10% deposit. They're borrowing $522,000 once stamp duty is included. One lender offers a variable rate with a fully linked offset account. Another offers a rate 0.15% lower but without offset and with exit fees if they want to refinance. If they regularly keep $15,000 to $20,000 in savings, the offset saves them more in interest than the lower rate delivers, even though the advertised figure looks less appealing.

Offset accounts and how they reduce interest

An offset account is a transaction account linked to your home loan where the balance reduces the amount of interest you're charged. If you owe $500,000 and keep $20,000 in offset, you only pay interest on $480,000. The money in offset remains accessible, which matters when unexpected costs appear or when you're building a deposit for an investment property down the line.

Not all offset accounts work the same way. A fully linked offset applies 100% of your balance against the loan. A partial offset might only apply 60% or 80%, which reduces its value significantly. Some lenders charge monthly fees for offset access. Others include it without additional cost but price it into a slightly higher rate. When you're comparing loan features, calculate the annual fee against the interest saved based on your actual savings pattern, not a theoretical balance you might maintain one day.

Fixed versus variable: decision points that matter

Fixed rates protect you from rate rises but lock you into restrictions. Most fixed loans limit extra repayments to $10,000 or $20,000 per year. If you sell the property or want to refinance before the fixed term ends, break costs apply. These costs reflect the difference between the rate you locked in and the rate the lender can now lend that money at. In a falling rate environment, break costs can reach tens of thousands of dollars.

Variable rates let you make unlimited extra repayments, redraw what you've paid ahead, and exit without penalty. If your income is irregular or you receive annual bonuses that you plan to put toward the loan, a variable structure gives you room to move. In our experience, first home buyers with two stable incomes and minimal savings after settlement often benefit from fixing a portion of the loan to create budget certainty, while keeping the remainder variable to absorb extra payments as their financial position improves.

Calculating what you'll actually pay

Rate comparison only tells you part of the story. Application fees, ongoing account fees, and package fees add hundreds or thousands of dollars annually. Some lenders waive application fees but charge higher ongoing fees. Others structure it the opposite way. The total cost over the period you expect to hold the loan is what matters, not the upfront number.

As an example, a $500,000 loan with a variable rate and a $395 annual package fee that includes offset might cost less over five years than a loan with no annual fee but a rate 0.20% higher and no offset, assuming you keep even a modest balance in the offset account. The calculators that factor in fees and offset balances give you a more accurate picture than comparing rates in isolation.

You also need to account for Lenders Mortgage Insurance if your deposit sits below 20%. LMI protects the lender if you default, and it's a one-off cost added to your loan amount. On a $520,000 loan with a 10% deposit, LMI might add $15,000 to $20,000 to what you owe. Some lenders price LMI lower than others, and some offer discounts for certain professions. When you're working out your borrowing capacity, LMI affects both your upfront costs and your ongoing repayments because you're paying interest on a larger amount.

Loan portability and future flexibility

Portability lets you transfer your existing loan to a new property without reapplying or paying discharge fees. If you're buying a starter home in Melbourne's inner west with plans to upgrade in five to seven years, a portable loan means you can take your current rate and structure with you. Not all lenders offer this, and those that do often attach conditions around the new property's value and your financial position at the time of transfer.

This feature matters more than most first home buyers realise when they're focused entirely on securing their first property. Rate discounts, offset access, and any package benefits you've negotiated stay in place when you port the loan. If rates have risen since you first borrowed, portability can save you from reapplying at higher rates or losing negotiated discounts that are no longer available to new customers.

How to structure your comparison

Start with your actual financial behaviour, not the loan features that sound appealing in theory. If you'll realistically keep $5,000 in savings and pay the minimum repayment each month, an offset account delivers minimal value and you're probably paying for a feature you won't use. If you're both in salaried roles with bonuses or regular overtime, the ability to make extra repayments and redraw if needed becomes more valuable than a slightly lower rate with restrictions.

Write down your deposit size, the amount you're borrowing, and any lump sums you expect to put toward the loan in the first few years. Then compare loan structures based on total interest paid over that period, factoring in fees and realistic offset balances. The loan that costs you the least over the time you'll actually hold it is the one that fits, regardless of which rate looks lowest on a comparison website.

When you're ready to move forward, having someone walk through the numbers based on your actual situation removes a lot of the uncertainty that comes with comparing products in isolation. Call one of our team or book an appointment at a time that works for you, and we'll work through the options from lenders across Australia to find the structure that matches how you'll use the loan.
