Avoid These 3 Mistakes When Choosing Your First Home Loan

Choosing a loan structure when you are borrowing $900,000 or more

Your first home loan structure locks in how much financial flexibility you have once you own the property. In Coorparoo, where the median two-bedroom unit sits at $825,000 and three-bedroom houses transact around $1.34 million, most first home buyers are borrowing heavily and need to understand how fixed, variable, and split loan options perform under different conditions.

Consider a buyer purchasing a two-bedroom unit near Coorparoo Square with a 10% deposit. They are borrowing $742,500 at current variable rates. If they lock the entire loan to a fixed rate and their circumstances change within two years, they face break costs that can run to thousands of dollars. If they choose variable and rates rise another 50 basis points, their repayments increase by roughly $230 per month. A split structure offers a middle path, but only if you split the loan in a way that matches your actual risk tolerance and cash position.

The structure you choose now will determine whether you can access your own equity when you need it, whether you can afford an unplanned rate rise, and whether refinancing later will cost you money or save it.

Fixed rate loans give you certainty but remove access to most flexible features

A fixed rate loan holds your interest rate steady for a set term, typically between one and five years. Your repayments do not change during that period regardless of what happens to the official cash rate or what lenders do with their variable products.

Most fixed rate products do not allow an offset account. Some permit a redraw facility, but lenders commonly restrict how much you can redraw and how often. If you receive a tax refund, a work bonus, or sell an asset and want to park that cash against your loan while keeping it accessible, a fully fixed loan will not give you that option in the way a variable product would.

Fixed loans also carry break costs if you repay the loan early, refinance, or pay down more than the contracted additional repayment limit before the fixed term ends. Break costs are calculated based on the difference between your fixed rate and the lender's cost of funds at the time you exit. If rates have fallen since you fixed, the break cost can be substantial. We regularly see buyers in Coorparoo who fixed during 2023 and 2024 now facing four-figure break costs when they try to refinance or sell earlier than planned.

Variable rate loans give you full access to offset and redraw but expose you to rate movements

A variable rate loan moves with the lender's standard variable rate, which generally tracks the Reserve Bank's cash rate over time. When rates rise, your repayments increase. When rates fall, your repayments decrease.

Variable products typically allow an offset account, which is a transaction account linked to your loan. Every dollar in the offset reduces the balance on which interest is calculated. If you are borrowing $742,500 and hold $20,000 in your offset, you pay interest on $722,500. The offset balance remains fully accessible, meaning you can use it for living expenses, emergencies, or planned purchases without applying for a redraw or breaking a fixed term.

Variable loans also allow unlimited additional repayments without penalty and give you the option to refinance at any time if a better rate or product becomes available. For first home buyers in Coorparoo who are managing tight cash flow or expect irregular income, that flexibility often outweighs the uncertainty of future rate movements.

The risk is that if rates rise further, your repayments increase and your buffer shrinks. At current settings, even a 25 basis point rise adds roughly $115 per month to a $742,500 loan. Buyers who have stretched their borrowing capacity to secure a property near the PA Hospital or within the Villanova College catchment need to model whether they can sustain those increases without financial stress.

Split loans let you hold both structures but require deliberate allocation

A split loan divides your borrowing between a fixed portion and a variable portion. You nominate the split at the time of settlement, commonly 50/50, but any ratio is possible.

The fixed portion gives you a base level of repayment certainty. The variable portion gives you access to an offset account and the ability to make extra repayments without restriction. If you later want to refinance or sell, you only pay break costs on the fixed portion, and only if rates have moved against you.

The structure only works if the split reflects your actual financial position. A 50/50 split is not automatically the right answer. If you have $30,000 in savings and expect to build that balance over the next two years, you want enough of the loan on the variable side to make the offset worth holding. If you have minimal savings and prioritise stable repayments above all else, a 70% fixed and 30% variable split may suit you better.

We regularly work with first home buyers in Coorparoo who initially request a 50/50 split without testing the numbers. When we model their actual cash flow and savings trajectory, many end up with a 60/40 or 70/30 structure that delivers more value for their circumstances.

How offset accounts reduce interest when you hold a buffer

An offset account only delivers value if you hold money in it. The account does not earn interest, but every dollar in the offset reduces the loan balance on which interest is charged, which has the same effect as earning interest at your loan rate.

If your loan rate sits at 6.20% and you hold $25,000 in your offset, you avoid paying interest on that $25,000. Over a year, that saves you roughly $1,550 in interest, which is equivalent to earning 6.20% on a savings account without paying tax on the interest.

For first home buyers, the challenge is building and maintaining that offset balance. If you are borrowing $742,500 to buy a unit in Coorparoo and your living expenses, strata fees, and loan repayments leave little room each month, the offset may sit near zero for the first 12 to 18 months. In that scenario, you are paying a slightly higher variable rate for a feature you are not yet using.

Offset accounts work when you have surplus income, irregular bonuses, or planned savings that you want to keep accessible while reducing your interest cost. If your cash flow is tight and you do not expect to build a buffer for several years, a variable loan with redraw rather than offset may be sufficient, or a higher fixed portion may reduce your rate and give you more repayment stability.

Redraw facilities let you access extra repayments but some lenders restrict timing and amounts

A redraw facility allows you to withdraw any additional repayments you have made above the minimum. If your minimum monthly repayment is $4,800 and you pay $5,000, the extra $200 becomes available for redraw.

Redraw is common on both variable and fixed loans, but the terms vary. Some lenders allow unlimited redraws with no fee. Others cap the number of redraws per year, charge a processing fee for each request, or require a minimum redraw amount. Fixed rate loans often impose stricter redraw conditions, and some lenders reserve the right to suspend redraw access if they determine you are using the facility too frequently or inconsistently with the original loan purpose.

We see buyers assume redraw and offset are interchangeable. They are not. Offset balances are held in a separate transaction account that you control. Redraw balances are held within the loan, and access depends on the lender's policy and processing time. If you need cash within 24 hours, an offset account gives you immediate access. A redraw request may take several business days, and in some cases may be declined.

For first home buyers using the Australian Government 5% Deposit Scheme to purchase in Coorparoo, loan features including offset and redraw availability depend on which participating lender you choose. Not all lenders on the panel offer offset accounts for low-deposit loans, and some restrict redraw on fixed terms entirely.

Why break costs on fixed loans can exceed $10,000 in a falling rate environment

Break costs apply when you exit a fixed rate loan before the fixed term ends. The cost is calculated based on the difference between the rate you fixed at and the lender's current cost of funding a loan for the remaining fixed period.

If you fixed at 6.50% for three years and you want to refinance after 18 months, the lender compares your rate to the wholesale rate they would now charge for an 18-month fixed term. If that rate has fallen to 5.80%, the lender has lost income, and you pay the difference as a break cost.

Break costs are not a flat fee. They are calculated using a formula that takes into account your loan balance, the rate difference, and the remaining term. On a $700,000 loan with 18 months remaining and a 70 basis point rate difference, break costs can easily exceed $10,000.

We have worked with buyers in Coorparoo who fixed in late 2023 when fixed rates were elevated and now want to sell or refinance as variable rates have fallen. Some face break costs that eliminate any potential saving from refinancing. Others are locked into a fixed rate that is now 80 to 100 basis points above current variable offerings but cannot afford the cost to exit early.

If you are considering a fixed loan or a split structure, model the cost of exiting early. Do not assume you will hold the property or the loan for the full fixed term. Job changes, relationship changes, and market opportunities all create reasons to refinance or sell earlier than planned.

First home buyer grants and stamp duty concessions in Queensland do not restrict your loan structure choice

Queensland offers a first home concession that removes transfer duty entirely on new homes regardless of value, provided at least one buyer is an Australian citizen, permanent resident or specified foreign retiree. For established homes, a concession reduces duty by up to $17,350 on properties valued under $710,000, phasing out at $800,000.

These concessions apply regardless of whether you choose fixed, variable, or split loan structures. Your loan product does not affect your eligibility for state-based duty relief or the $15,000 First Home Owner Grant on eligible new homes under $750,000.

The same applies to the Australian Government 5% Deposit Scheme. The scheme allows you to purchase with a 5% deposit without paying Lenders Mortgage Insurance, but loan structure is determined by the participating lender, not by the scheme itself. Some lenders on the panel offer fixed, variable, and split options. Others restrict low-deposit borrowers to variable products only. You need to confirm product availability with the lender before you assume a particular structure will be available.

Splitting a loan 70/30 or 60/40 often suits buyers with modest offset balances better than 50/50

A 50/50 split is the default many buyers request, but it is not always the most useful allocation. The value of the variable portion depends on how much cash you can hold in the offset and how often you plan to make additional repayments.

If you are borrowing $750,000 and expect to hold an average offset balance of $15,000 to $20,000, a 70% fixed and 30% variable split gives you enough variable debt to make the offset effective while locking in repayment certainty on the majority of the loan. A 50/50 split in that scenario gives you more variable debt than your offset balance can usefully cover, and you pay a higher rate on that variable portion without gaining additional value.

We worked with a buyer purchasing a three-bedroom unit near Old Cleveland Road who initially wanted a 50/50 split on a $780,000 loan. Their savings sat at $18,000 and their monthly surplus was roughly $1,200. We modelled a 70/30 split with $210,000 on variable and the rest fixed. Over the first two years, the offset balance averaged $22,000, covering most of the variable portion and saving roughly $2,700 in interest compared to holding the same balance against a 50/50 split with higher variable exposure and a lower average rate benefit.

The right split depends on your actual cash position, not on an assumption that 50/50 is balanced. Model your savings, your monthly surplus, and your expected offset balance before you lock in the structure.

When to choose variable over fixed if you plan to upgrade within three years

If you are buying your first home in Coorparoo with the intention of upgrading to a larger property or a different suburb within three years, a variable loan avoids the risk of break costs and gives you full flexibility to sell or refinance when the time comes.

Buyers who fix for three or five years and then sell in year two face break costs that can absorb much of the equity gain, particularly if rates have fallen or if the property has not appreciated as much as expected. A variable loan allows you to sell, refinance, or port the loan to a new property without penalty.

Variable loans also allow you to increase your repayments or park lump sums in an offset without restriction, which helps you build equity faster if you are planning to use that equity as a deposit for the next purchase. Fixed loans cap additional repayments at a set amount per year, typically $10,000 to $30,000 depending on the lender, and do not allow offset accounts in most cases.

The trade-off is repayment volatility. If you are borrowing close to your maximum borrowing capacity and rates rise during your holding period, your repayments increase and your ability to save for the next deposit decreases. You need to model whether you can sustain a rate rise of 50 to 75 basis points and still meet your savings target for the upgrade.

Choosing your loan structure is not about predicting rates but about matching features to your cash position and timeline

Most first home buyers approach loan structure as a question of whether rates will rise or fall. If they think rates will fall, they fix. If they think rates will rise, they choose variable. That logic reverses the actual decision.

Your loan structure should reflect your cash flow, your savings balance, your plans for the property, and your tolerance for repayment changes. If you have a stable income, minimal savings, and no plans to sell or refinance for five years, a fixed loan gives you repayment certainty and a slightly lower rate in many cases. If you have irregular income, expect bonuses or windfalls, and want the ability to access your own money while reducing interest, a variable loan with offset suits you.

A split loan is not a hedge. It is a tool for buyers who want partial certainty and partial flexibility, and it only works if the split reflects how much cash you can actually hold in the offset and how much repayment stability you need.

We regularly see buyers in Coorparoo choose a structure based on what they think the Reserve Bank will do next, then find themselves locked into a fixed rate they cannot afford to exit or a variable loan they cannot afford to hold when repayments rise. The right structure is the one that gives you the features you will use and the flexibility you need for your actual situation, not the one that performs perfectly if rates move the way you expect.
