Simple hacks to buy in a better school zone

Families moving to secure a spot in a school catchment often face a choice between the property they want and the property they can afford.

The difference between being inside or outside a catchment boundary can add $100,000 or more to the purchase price in some suburbs, and the financial pressure increases when you're already committed to a specific enrolment date. Getting the structure of your home loan right before you start searching gives you more options when the right property comes up.

Should you fix, split or stay variable when buying for school access

A variable rate gives you full repayment flexibility, which matters when you're managing school fees, uniforms, and other education costs on top of a mortgage. You can make extra repayments without penalty and redraw if an unexpected expense comes up. Most lenders also offer an offset account with a variable loan, which reduces the interest you pay while keeping your savings accessible.

A fixed rate locks in your repayment amount for a set period, usually between one and five years. This can help with household budgeting, particularly if you're coordinating a move with a school start date and want certainty around your monthly expenses. The downside is limited flexibility. If you want to make extra repayments beyond a small annual allowance, you'll usually face break costs, and most fixed rate products don't include an offset.

A split loan combines both structures. You might fix half your loan amount to lock in a portion of your repayments and keep the other half variable for flexibility and offset access. This approach works well for families who want some budget certainty but also need room to manage fluctuating costs as children move through school years.

How borrowing capacity changes with income and deposit size

Lenders assess your borrowing capacity by applying a serviceability buffer of at least 3.0 percentage points above the loan product rate. If the variable rate on offer is 6.2%, the lender tests whether you can service the loan at 9.2% or higher. They also factor in your existing debts, living expenses, and any dependants.

Consider a family with a combined income of $150,000, minimal other debts, and two children. At current variable rates, they might qualify for a loan amount around $750,000 to $800,000, depending on the lender's assessment. If they can increase their deposit from 10% to 15%, they reduce the amount they need to borrow and may avoid Lenders Mortgage Insurance, which can add several thousand dollars to the upfront cost. A larger deposit also improves your loan to value ratio, which can unlock better interest rate discounts with some lenders.

We regularly see families underestimate how much their regular childcare, school fee commitments, and extracurricular costs affect what a lender will approve. Declared expenses are one of the biggest factors in the final loan amount offered, so it's worth reviewing your spending in detail before you apply.

Using pre-approval to move quickly in high-demand catchments

School catchment properties move quickly, particularly in the months before enrolment deadlines. Home loan pre-approval gives you a conditional commitment from a lender based on your financial position, usually valid for three to six months. It doesn't lock in an interest rate, but it does confirm the loan amount you can access and speeds up the process once you find a property.

Pre-approval also gives you confidence to make an offer without a finance clause in competitive situations, though you should weigh that decision carefully with your broker and conveyancer. If your financial position changes between pre-approval and settlement, such as a job change or new debt, the lender may reassess your application.

Some families apply for pre-approval across two or three adjacent suburbs within the same school network, giving them flexibility to act on whichever property offers the most value. This approach works particularly well in areas where catchment boundaries create sharp price differences over short distances.

What happens if you need to borrow more than the price cap for a government scheme

The Australian Government 5% Deposit Scheme has property price caps that vary by location. In NSW, the cap is $1,500,000 in capital cities and regional centres. In Victoria, it's $950,000 in capital cities and regional centres. In Queensland, it's $1,000,000 in capital cities and regional centres, and in Western Australia, it's $850,000 in the same areas.

If the property you want exceeds the cap, you won't be able to use the scheme. In that situation, you either need to save a larger deposit or pay LMI to bring your deposit up to what the lender requires. Some families choose to purchase a less expensive property within the catchment first, build equity over a few years, and then upgrade to a larger home once their financial position improves.

Another option is Help to Buy, where the government contributes up to 30% of the purchase price for an existing home in exchange for an equivalent equity share. Income limits apply: $103,000 for individuals and $165,000 for joint applicants from 1 July 2026. The scheme has its own property price caps, which you can check using the postcode search tool at firsthomebuyers.gov.au. You can't combine Help to Buy with the 5% Deposit Scheme, but you can use it alongside most state and territory stamp duty concessions.

How principal and interest versus interest only affects your long-term position

Most families buying in a school catchment take out a principal and interest loan, where each repayment reduces the loan balance and builds equity in the property. This structure suits owner-occupiers who plan to stay in the home long-term and want to own it outright by retirement.

An interest only loan means you pay only the interest portion for a set period, usually one to five years, and the loan balance stays the same. Repayments are lower during the interest only period, which can help if you're managing a tight budget in the early years. However, once the interest only period ends, your repayments increase significantly because you then need to pay off the principal over the remaining loan term.

Interest only is more common for investment loans, where investors want to maximise tax deductions and preserve cash flow. For an owner-occupied purchase, principal and interest is usually the better choice unless you have a specific short-term cash flow reason to delay paying down the loan balance.

When refinancing makes sense after you've moved into catchment

Once you've settled into your home and your financial position has improved, refinancing can reduce your interest rate, switch your loan structure, or release equity for renovations or other expenses. If you took out your original loan with a higher interest rate or LMI because your deposit was small, refinancing after a year or two of strong repayments and property value growth can lower your ongoing costs.

Refinancing also lets you consolidate debts, add an offset account if your current loan doesn't include one, or move from a fixed rate to a variable rate if your circumstances have changed. Lenders generally require a new valuation and serviceability assessment, so it's worth running the numbers with your broker before you commit to the switch.

Some families refinance to access equity and fund private school fees, tutoring, or extracurricular programs once their children are settled in the catchment. This approach works if your property value has increased and your income supports the higher loan amount, but it does mean taking on more debt, so it's not suitable for everyone.

Whether you're buying your first home in catchment or upgrading to a larger property in the same school network, the structure of your loan should match your household's income, expenses, and timeline. Call one of our team or book an appointment at a time that works for you.
