Getting the structure of your investment loan right from the start matters more than most property investors in Toongabbie realise.
The decisions you make when setting up finance, whether you're buying your first rental property near Memorial Avenue or adding a second dwelling to your portfolio closer to the station precinct, affect your borrowing capacity, your monthly cash flow, and your ability to claim deductions. With changes to negative gearing rules taking effect from July 2027, the way you set up your loan now will influence how those changes affect you later.
Why Loan Structure Matters Before You Apply
Your loan structure determines how much interest you can claim, how easily you can access equity later, and whether you can borrow again without refinancing everything.
Consider an investor buying a two-bedroom unit in Toongabbie with a 20 per cent deposit. If they take out a single loan for the purchase amount and later want to access equity for a second property, they'll need to refinance the entire balance or apply for a separate top-up. If instead they split the loan into two accounts at the start, one at 80 per cent loan to value ratio and a second smaller facility, they can draw on the second account without touching the first. That flexibility becomes valuable when you want to move quickly on another purchase or cover renovation costs without triggering a full application process.
Splitting loans also makes it easier to keep investment and private borrowings separate. If you later use equity to buy a car or pay for a holiday, that portion of the debt is no longer deductible. A separate loan account for private purposes keeps your records clear and your deductions intact.
Interest Only or Principal and Interest for Investment Property
Interest only repayments reduce your monthly outgoings and preserve your borrowing capacity, but they don't build equity through loan reduction.
For an investment loan in Toongabbie, interest only can make sense if rental income doesn't cover the full principal and interest repayment, or if you're planning to sell within a few years and want to keep more cash available for other investments. Lenders typically allow interest only for five years on investment lending, after which the loan reverts to principal and interest unless you apply to extend.
Principal and interest repayments cost more each month but reduce your loan balance and increase your equity. If you're holding the property long-term and can afford the higher repayment, paying down the loan steadily can give you a larger buffer when interest rates rise or if the property sits vacant between tenants.
In our experience, investors who plan to acquire multiple properties within a short period often choose interest only to keep their debt serviceability as high as possible. Those holding a single property as a long-term income stream tend to favour principal and interest once they're confident the rental income is stable.
Fixed or Variable Rate for Toongabbie Investment Property
A variable rate gives you flexibility to make extra repayments, redraw funds, and refinance without break costs, but your repayments will move with rate changes.
A fixed rate locks in your repayment for a set period, usually one to five years, and protects you from rate rises during that time. The trade-off is limited flexibility. Most fixed rate products don't allow extra repayments beyond a small annual threshold, and if you refinance or sell before the fixed term ends, you'll pay break costs that can run into thousands of dollars.
Some investors split their loan between fixed and variable portions. In a scenario like this, you might fix 60 per cent of the balance to protect most of your repayment from rate rises, and leave 40 per cent variable so you can make extra repayments or access a redraw facility if your circumstances improve. The split approach works well if you value certainty but don't want to lock yourself in completely.

Using Equity from Toongabbie Property to Fund the Next Purchase
Equity release lets you borrow against the value of property you already own without selling it.
If you own a home in Toongabbie that's increased in value, a lender can assess how much usable equity you have by taking 80 per cent of the current property value and subtracting what you owe. That difference, minus costs, can be used as a deposit for an investment property. Because you're not selling your home, you keep the long-term capital growth on both properties.
Consider a homeowner in Toongabbie whose property has grown in value over the past few years. They owe less than half the property's current worth. By refinancing and drawing on that equity, they can fund a 20 per cent deposit and costs on a rental property without needing to save a separate cash deposit. The new lending is structured so the investment loan is separate from the home loan, which keeps the interest deductions clear.
Equity lending does increase your total debt, and the lender will assess whether your income can service both loans. If rental income on the new property doesn't fully cover the repayment, the lender will factor in the shortfall when calculating your borrowing capacity. That's where loan structure and repayment type make a difference. Choosing interest only on the investment loan can reduce the monthly commitment enough to meet serviceability.
Rate Discounts and How They're Applied to Investment Lending
Lenders don't advertise a single interest rate for all borrowers. The rate you're offered depends on your loan size, deposit, and the lender's current appetite for investment lending.
Investment loans generally attract a higher rate than owner-occupied lending, typically between 0.15 and 0.50 percentage points above the equivalent home loan rate. Within that, borrowers with a deposit of 20 per cent or more, a clean credit file, and strong income documentation will receive a better discount than someone borrowing at 90 per cent loan to value ratio with Lenders Mortgage Insurance.
Rate discounts can also vary depending on the loan amount. A borrowing of $600,000 might attract a deeper discount than a $300,000 loan with the same lender, because the larger balance is more profitable over the life of the loan. Some lenders offer additional discounts if you hold a transaction account or salary package with them, though the benefit is often small and shouldn't drive the decision if another lender offers better loan features.
When you refinance an investment loan, you're not limited to your current lender's retention offers. Shopping your loan across multiple lenders can uncover a lower rate or better loan features, and a broker can show you what's available without you needing to lodge multiple applications.
Maximising Deductions While Staying Within ATO Rules
Interest on borrowings used to purchase or hold a rental property is deductible, but only to the extent the property is used to produce income.
If you borrow to buy an investment property in Toongabbie and later redraw funds from that loan to pay for a private holiday, the interest on the redrawn portion is not deductible. The ATO treats the use of funds as the determining factor, not the security the loan is attached to. Keeping investment and private purposes in separate loan accounts makes it clear which interest you can claim.
Other claimable expenses include property management fees, council rates, water charges, building insurance, repairs, and depreciation on fixtures and fittings. Body corporate fees for units are also deductible. Loan establishment fees and Lenders Mortgage Insurance premiums can be claimed over five years or the life of the loan, whichever is shorter.
Under current rules, if your rental expenses exceed your rental income, you can offset that loss against your other income, including salary. From July 2027, new rules will quarantine losses on most residential investment properties acquired after May 2026, meaning you can only offset those losses against other rental income or carry them forward. Properties you already own, or those under contract before the announcement, will continue under existing negative gearing rules. Eligible new residential dwellings that add to housing supply will still allow full negative gearing even after July 2027.
Debt to Income Limits and How They Affect Investor Borrowing
Since February 2026, lenders have been required to limit the proportion of new loans they write at a debt to income ratio of six times or greater.
Your debt to income ratio compares your total borrowings, including the new loan, to your gross annual income. If you earn $100,000 and want to borrow $650,000 across all loans, your DTI is 6.5. Lenders can still approve loans above six times income, but only up to 20 per cent of their total new investor lending can fall into that category.
In practice, this means borrowers with high incomes relative to their debt will find it easier to secure investment lending. Borrowers already carrying significant debt, or those with moderate incomes, may find their borrowing capacity capped earlier than it would have been under serviceability assessment alone. The DTI cap applies separately to investor and owner-occupied lending, so your investment borrowing is measured against the lender's investor portfolio limit, not their overall book.
If you're planning to build a new dwelling or buy a newly constructed property, that lending is exempt from the DTI cap. The exemption applies to finance for construction and for the purchase of dwellings that meet the definition of newly erected under the relevant accounting standard. Refinancing existing debt or purchasing established property does not qualify.
When to Review Your Loan Structure After Settlement
Your loan structure should match your current goals, and those goals shift as your portfolio grows or your personal circumstances change.
If you took out an interest only loan five years ago and it's about to revert to principal and interest, you'll need to decide whether to extend the interest only period, switch to principal and interest, or refinance to a different lender with better terms. If your income has increased or the property has grown in value, you might have more options now than you did at the start.
If you've paid down a portion of your loan and want to access that equity for another investment, restructuring into a split loan or establishing a line of credit against the property can give you faster access than applying for a new loan each time. If your current loan doesn't allow redraws or has high fees for additional borrowing, refinancing to a more flexible product can save time and cost over the long term.
Changes to tax rules, including the quarantining of losses from July 2027 and the shift from the capital gains tax discount to indexation for new properties, mean your loan structure now affects not just your cash flow but your after-tax position years into the future. Reviewing your lending every few years, particularly before acquiring another property, helps you stay ahead of both regulatory and market changes.

Frequently Asked Questions
Should I choose interest only or principal and interest for an investment property loan?
Interest only reduces your monthly repayments and preserves borrowing capacity, making it useful if you plan to acquire more properties soon or if rental income doesn't cover a full principal and interest repayment. Principal and interest costs more each month but builds equity and gives you a buffer against rate rises or vacancy.
Can I still negatively gear a property I buy in Toongabbie now?
Yes, under current rules. From July 2027, losses on residential investment properties purchased after May 2026 will be quarantined and can only offset rental income or capital gains, unless the property is an eligible new build that increases housing supply. Properties you already own or have under contract before May 2026 continue under existing rules.
How do I use equity in my Toongabbie home to buy an investment property?
A lender can assess your usable equity by taking 80 per cent of your property's current value and subtracting what you owe. The difference, minus costs, can be used as a deposit for an investment property. You'll need to refinance or establish a new loan facility to access that equity, and the lender will assess whether your income can service both loans.
What is the debt to income cap and how does it affect investment borrowing?
Since February 2026, lenders can only write up to 20 per cent of new investment loans at a debt to income ratio of six times gross income or higher. If your total debt, including the new loan, is more than six times your annual income, you may still be approved, but lenders have less capacity to lend in that range.
When should I review my investment loan structure?
Review your loan when your interest only period is ending, when you want to access equity for another purchase, or when your income or goals have changed. Changes to tax rules from July 2027 also make it worth reviewing how your loan structure affects your after-tax position before acquiring another property.
