The Pros and Cons of Your First Home Loan

Your first home loan is the biggest financial commitment most people make, and the structure you choose shapes your repayments, flexibility, and equity for years to come.

The decision isn't just about getting approved. It's about choosing a loan that fits how you live, how your income might change, and what you need from the property in the first few years. A fixed rate offers certainty, but locks you in. A variable rate gives you flexibility, but exposes you to rate movements. Government schemes can reduce your deposit, but come with property price caps and lender panels. Each option carries trade-offs, and understanding those trade-offs before you commit saves you from restructuring later.

Fixed Rate vs Variable Rate: What You Give Up for What You Gain

A fixed rate home loan locks your interest rate for a set period, usually one to five years, giving you certainty over your repayments. A variable rate moves with the market, which means your repayments can rise or fall depending on what the Reserve Bank and your lender decide.

Consider a buyer purchasing in Sippy Downs at the suburb's current median of around $1,027,000. With a 10% deposit and a fixed rate, their repayments stay the same for the fixed term, which makes budgeting straightforward if they're on a single income or managing other commitments like childcare. But if rates drop during that period, they don't benefit. And if they want to sell or refinance before the fixed term ends, they may face break costs that run into thousands of dollars. On a variable rate, the same buyer has the flexibility to make extra repayments, redraw funds, or switch lenders without penalty, but they carry the risk that their repayments could increase if rates rise. For someone expecting a pay rise, planning renovations, or unsure how long they'll stay in the property, that flexibility often outweighs the risk.

How the Australian Government 5% Deposit Scheme Changes the Equation

The Australian Government 5% Deposit Scheme allows eligible first home buyers to purchase with a deposit of just 5% without paying lenders mortgage insurance. Housing Australia guarantees up to 15% of the property value to the lender, bringing the combined deposit and guarantee to 20%.

In Queensland, the property price cap is $1,000,000 in capital cities and regional centres including the Sunshine Coast and Gold Coast, and $700,000 in other areas. Both the purchase price and the lender's assessed value must sit at or below the cap. Applications are made through participating lenders, not directly through Housing Australia. The scheme works with fixed, variable, and split loan structures depending on the lender. No income limits apply, and there are no annual place limits anymore, which means the scheme is now open to a much wider group of buyers than it was in previous versions.

For a buyer looking at Caloundra West near the Aura development, where the median house price sits around $950,000, the scheme brings the property within reach with a $47,500 deposit instead of the $190,000 they'd need for a traditional 20% deposit. That difference can be the margin between buying now and waiting another two years while prices continue to move. But the scheme requires you to use a lender on the Housing Australia panel, which may limit your ability to access certain loan features or rate discounts available elsewhere. It's a trade-off between deposit size and product choice, and for most first home buyers, the deposit reduction wins.

Split Rate Loans: Flexibility Without Going All In

A split rate loan divides your borrowing between a fixed portion and a variable portion, usually in a ratio you choose with your broker. The fixed portion gives you repayment certainty, while the variable portion lets you make extra repayments, access an offset account, and benefit from any rate cuts.

This structure works well when you want some protection but don't want to give up all your flexibility. In our experience, buyers who receive irregular income, such as shift workers or sole traders, often split 50/50 or 60/40 in favour of the variable portion so they can park lump sums in an offset account when cash flow is strong, then draw on those savings when work slows down. A split loan also reduces the impact of break costs if you need to sell or refinance during the fixed period, because only the fixed portion is subject to those fees. The variable portion can be adjusted or paid down without penalty.

What LVR Means for Your Interest Rate and Flexibility

Your loan-to-value ratio is the percentage of the property value you're borrowing. If you borrow $800,000 to buy a property valued at $1,000,000, your LVR is 80%. The lower your LVR, the lower your interest rate and the more loan features you can access.

Lenders price their loans in LVR bands. A borrower at 80% LVR typically receives a better interest rate than a borrower at 90% LVR, even if every other aspect of their application is identical. This is because the lender's risk is lower. At LVRs above 80%, you'll also pay lenders mortgage insurance, which protects the lender if you default but adds thousands of dollars to your upfront costs. Under the Australian Government 5% Deposit Scheme, the LMI is waived because Housing Australia provides the guarantee, but you're still borrowing at 95% LVR, which means your equity position is thin and you'll need to be careful about serviceability if rates move.

For buyers using the scheme in suburbs like Buderim, where the median house price is $1,375,000, you're outside the Sunshine Coast cap and would need to look at either a cheaper property or a larger deposit. But in Mountain Creek, where the median is $1,210,000, you're still outside the cap. Nambour, at a median of $862,490, sits comfortably within it and offers one of the strongest rental yields in the region at 4.21%, which can help with serviceability if you're planning to rent out a room or move into the property as an investment later.

Offset Accounts and Why They Matter More Than Extra Repayments

An offset account is a transaction account linked to your home loan where the balance reduces the interest you're charged. If you have $20,000 in your offset and owe $800,000 on your mortgage, you only pay interest on $780,000.

The benefit is that your money remains accessible. You're not locking it into the loan as an extra repayment, which means you can pull it out for an emergency, a renovation, or another investment without needing to reapply or redraw. This is especially useful for first home buyers who are still building financial stability and may need access to cash quickly. Offset accounts are almost always linked to variable rate loans or the variable portion of a split loan. Fixed rate loans rarely offer them, which is another reason pure fixed loans can feel restrictive once you've been in the property for a year or two and your cash flow has improved.

Queensland First Home Concessions: What You Can Actually Use

Queensland offers a $15,000 First Home Owner Grant for new homes valued under $750,000, which applies to contracts signed from 1 July 2026. The grant does not apply to established homes. For established homes, Queensland provides a first home concession that reduces stamp duty by up to $17,350 for properties valued up to $709,999, phasing out to nil at $800,000. For new homes, a full transfer duty concession applies with no price cap, reducing duty to nil on the residential land component.

If you're buying an established home in Tewantin at the current median of around $1,250,000, you won't receive the grant or the maximum stamp duty concession because the property value exceeds the thresholds. But if you're buying in Caloundra at $939,000, you'll receive a partial stamp duty concession on the established home, or full duty relief if you're buying new. These concessions can be combined with the Australian Government 5% Deposit Scheme, which makes them more powerful together than separately. A first home buyer using both the scheme and the state concession can enter the market with a 5% deposit, no LMI, and reduced or zero stamp duty, which compresses the upfront cash requirement dramatically.

How Lenders Assess Serviceability and Why It Tightens Your Borrowing

Every lender must assess your ability to service a home loan at a rate that's at least 3.0 percentage points above the actual loan rate. This is the serviceability buffer, and it's set by APRA to protect borrowers from rate rises.

If you're applying for a variable rate loan at 6.5%, the lender will test whether you can afford repayments at 9.5%. For a $900,000 loan, that's the difference between around $6,000 per month and $7,500 per month. The buffer reduces how much you can borrow, sometimes significantly. But it also protects you. Buyers who stretch to the absolute limit of their borrowing capacity often find themselves under pressure within the first year if rates move or their circumstances change. Working with a mortgage broker means your serviceability is stress-tested before you start looking at properties, so you're searching in the right price range from the beginning.

Pre-Approval: Why It's Not a Guarantee But Still Worth Having

Pre-approval gives you conditional approval for a loan amount based on your income, expenses, and credit history. It's not a guarantee, because final approval depends on the property valuation, your employment status at settlement, and whether your financial position has changed since the pre-approval was issued.

But pre-approval still matters. It tells you what you can borrow, it shows sellers you're a serious buyer, and it shortens the time between contract and settlement because most of the lender's assessment is already done. In competitive markets like Maroochydore, where the median house price is $1,250,000 and the CBD transformation is driving demand, having pre-approval can be the difference between your offer being accepted or passed over for another buyer who's ready to move faster. Pre-approvals are usually valid for three to six months, and they're based on the information you provide at the time, so if your income drops, your expenses increase, or you take on new debt, the lender can withdraw or reduce the approval.
