Everything You Need to Know About the Home Buying Process

Understanding How Lenders Assess Your Application

Lenders assess your capacity to service a loan by testing your income against your expenses and adding a buffer of 3.0 percentage points above the actual loan product rate. This means even if you're applying for a variable rate of 6.2%, the lender will assess whether you can service repayments at 9.2%. The buffer has been in place since late 2021 and applies to all new borrowers, whether you're buying in South Brisbane or anywhere else in Australia.

Consider a buyer who earns $95,000 annually and has rental commitments of $2,400 per month in West End. The lender will calculate their monthly income after tax, subtract committed expenses including that rent, and then test whether the remaining amount can service a loan at the buffered rate. If the buyer is borrowing $550,000, the lender will assess repayments at roughly 9.2%, not the actual rate on offer. This means the borrower needs to demonstrate they can afford repayments of around $4,800 per month, even though the actual repayment at 6.2% would be closer to $3,400. The difference between what you can afford in theory and what the lender will approve comes down to that serviceability buffer.

Debt-to-income limits also apply. From February 2026, banks can lend no more than 20% of their new owner-occupier loans to borrowers with a total debt level of six times their income or more. For someone earning $95,000, that threshold sits at $570,000. Borrowing above that level is still possible, but it falls within the lender's restricted allocation and may attract closer scrutiny or require a stronger application overall.

Pre-Approval and What It Actually Covers

Pre-approval gives you conditional approval for a loan amount before you've found a property. The lender assesses your income, expenses, credit history and borrowing capacity and issues a letter confirming how much they're willing to lend, subject to a satisfactory property valuation and no material change in your circumstances. Most pre-approvals are valid for three to six months.

In South Brisbane, where the median unit price has been moving quickly around the $500,000 to $600,000 mark depending on the building and proximity to the Brisbane River, pre-approval lets you move with confidence once you find something suitable. It also signals to selling agents that you're a serious buyer, which can matter in a competitive offer situation.

Pre-approval does not lock in a rate. Rates are confirmed when you formally apply and submit a contract of sale. If rates move between pre-approval and formal application, your loan will reflect the current pricing at the time you proceed. Pre-approval also doesn't cover the property itself. If the property you choose is affected by flood overlays, has structural concerns flagged in a building report, or the valuation comes in below the contract price, the lender may decline to proceed even with a valid pre-approval in place.

Choosing Between Variable, Fixed and Split Rate Structures

A variable rate moves with the market and gives you flexibility to make extra repayments, redraw funds, or refinance without break costs. A fixed rate locks your repayment amount for a set period, typically one to five years, and protects you from rate rises during that term. Break costs apply if you repay the loan early, refinance, or make repayments above the agreed threshold during the fixed period.

A split loan divides your borrowing between fixed and variable portions. You might fix 50% of a $600,000 loan at 5.89% for three years and leave the other 50% on a variable rate of 6.19%. This structure gives you partial protection from rate increases while retaining some flexibility to make extra repayments on the variable portion. The variable portion can also be linked to an offset account, which reduces the interest you pay by offsetting your savings balance against the outstanding loan balance.

In a rising rate environment, fixing part of your loan can provide budget certainty. In a falling rate environment, you benefit immediately on the variable portion while waiting for the fixed term to expire. There's no universal right answer. Your choice depends on your income stability, your tolerance for repayment fluctuation, and whether you're likely to make lump sum repayments or sell within the fixed term.

The Role of Lenders Mortgage Insurance

Lenders mortgage insurance is required when your deposit is less than 20% of the property value. The premium is paid by you, the borrower, and it protects the lender in the event of default. It does not protect you. The cost is calculated on a sliding scale based on your loan amount and loan-to-value ratio. The higher your LVR, the higher the premium.

For a $550,000 purchase in South Brisbane with a 10% deposit, the LVR is 90%. The LMI premium on a loan of $495,000 might range from $15,000 to $20,000 depending on the lender and insurer. That premium can be capitalised into the loan or paid upfront. If you capitalise it, you're borrowing more and paying interest on the premium over the life of the loan.

The Australian Government 5% Deposit Scheme removes the need for LMI by providing a guarantee to participating lenders. For first home buyers in South Brisbane, this can mean the difference between waiting another two years to save a larger deposit or entering the market sooner. The scheme has no income cap and no annual place limit. Property price caps in Queensland are $1,000,000 in Brisbane and $700,000 in other areas. Eligibility is assessed by the participating lender, and you'll need to meet their standard serviceability requirements even if the LMI cost is waived.

What Happens Between Contract and Settlement

Once your offer is accepted and the contract is signed, the lender orders a valuation of the property. The valuer is independent and their role is to confirm the property is worth what you've agreed to pay. If the valuation comes in below the contract price, the lender will only provide a loan based on the lower figure. You'll need to find the shortfall or renegotiate with the seller.

The lender will also review your employment status, run a final credit check, and confirm that nothing material has changed since pre-approval. Changing jobs, taking on new debt, or missing a credit card payment during this period can delay or derail your application. Once the loan is formally approved, the lender instructs their solicitor or settlement agent to prepare the mortgage documents. Your conveyancer coordinates with the seller's conveyancer and the lender to arrange settlement, which is when ownership transfers and funds are exchanged.

Settlement periods in Queensland are typically 30 to 90 days depending on what's agreed in the contract. Shorter settlement periods suit sellers who want certainty. Longer periods give you more time to arrange finance, complete building and pest inspections, and finalise your logistics. Your conveyancer will also calculate adjustments for council rates, water rates, and body corporate levies if you're buying a unit, and ensure those amounts are settled fairly between you and the seller.

How Offset Accounts Work in Practice

An offset account is a transaction account linked to your loan. The balance in the offset account reduces the amount of interest you're charged each month without actually reducing the loan balance. If you have a $500,000 loan and $30,000 sitting in a linked offset, you'll only pay interest on $470,000.

Offset accounts are usually available on variable rate loans and the variable portion of split loans. They're not commonly offered on fixed rate products. The benefit of an offset is that your savings remain accessible while still working to reduce your interest cost. This is particularly useful if you're managing irregular income, saving for upcoming expenses like renovations, or simply want the option to access funds without redrawing from the loan itself.

For owner-occupiers, the interest saved through an offset account is a direct reduction in your cost of holding the property. The more you keep in the offset, the less interest you pay and the faster you build equity, assuming you continue making your standard repayments. Some lenders charge a higher rate or an annual fee for loans with offset features, so it's worth confirming the net benefit before committing.
