The Pros and Cons of Investment Loan Products

Choosing between investment loan products is less about finding the lowest rate and more about matching loan features to your property strategy.

Most lenders offer dozens of investment loan variations, but the decisions that actually affect your cash flow and portfolio growth come down to three comparisons: variable versus fixed rates, interest-only versus principal and interest repayments, and whether you need offset or redraw. Each choice has trade-offs that depend on your income stability, tax position, and whether you're holding the property for rental yield or capital growth.

Variable Rate or Fixed Rate for Investment Property

Variable rates give you flexibility to make extra repayments and access features like offset accounts, while fixed rates lock in your repayment amount for a set period but usually restrict additional payments and don't allow offset.

If you're holding a property in Trigg for long-term capital growth and plan to use rental income to cover most of the loan, a variable rate with an offset account lets you park any surplus cash and reduce interest without losing access to those funds. The offset reduces the loan balance used to calculate interest, which can make a meaningful difference over time. Fixed rates suit investors who want certainty around repayments and aren't planning to pay down the loan ahead of schedule. You won't benefit from rate cuts, but you also won't be caught out by rate rises during the fixed period.

Consider an investor who purchases a two-bedroom apartment near Trigg Beach with the intention of holding it for ten years. Rental income covers 80% of the loan repayment, and the investor uses an offset account to hold a $20,000 emergency buffer. That buffer reduces the interest charged each month without being locked away. If the investor had chosen a fixed rate, that $20,000 would sit in a separate savings account earning minimal interest while the loan accrues interest on the full balance.

Interest-Only Repayments Versus Principal and Interest

Interest-only repayments keep your monthly outgoings lower and maximise your tax deductions, but you're not reducing the loan balance. Principal and interest repayments cost more each month but build equity and reduce your debt over time.

Interest-only periods typically last between one and five years, after which the loan reverts to principal and interest unless you negotiate an extension. If your property is neutrally geared or close to it, keeping repayments interest-only means you can claim the full interest cost as a deduction while freeing up cash flow to cover other expenses or invest elsewhere. If you're in a high tax bracket and the property is negatively geared, the deduction benefit is larger.

Principal and interest repayments make sense if you're planning to pay down the investment loan over time or if you want to build equity that can be used to fund future property purchases. You'll pay more each month, but the loan balance drops and you're reducing the total interest paid. In our experience, investors who plan to sell within five to seven years often prefer principal and interest, while those building a portfolio with multiple properties lean toward interest-only to preserve borrowing capacity.

Loan Features That Affect Flexibility and Cost

Offset accounts, redraw facilities, and the ability to make extra repayments all add flexibility, but not every investment loan includes them. Offset accounts are more common with variable rate loans and reduce the interest you're charged without locking funds into the loan. Redraw facilities let you make extra repayments and withdraw them later, but some lenders charge fees or restrict how often you can access those funds.

If you're comparing two investment loan options with similar interest rates, check whether the loan includes an offset and whether there's an annual package fee. Some lenders charge $395 per year for a package that includes offset and rate discounts. Others offer no annual fee but don't include offset. The right choice depends on how much surplus cash you're likely to hold and whether you need access to it.

Trigg investors who own multiple properties often use offset accounts to centralise cash flow across their portfolio, parking rental income and personal savings in the one account linked to the investment loan with the highest balance. That approach reduces interest across the board without splitting funds into separate redraw facilities.

Comparing Interest Rate Discounts and Ongoing Costs

Investor interest rates are typically higher than owner-occupier rates, but the size of the rate discount depends on your loan amount, deposit size, and whether you're using a broker to access wholesale pricing.

Most lenders offer a standard variable rate for investment loans, then apply a discount based on loan size and LVR. A loan with a 20% deposit and a balance over $500,000 will generally qualify for a larger discount than a loan with a 10% deposit and a balance under $300,000. Some lenders also reserve their lowest rates for new customers, which is one reason refinancing can result in a lower rate even if you stay with the same lender.

Rate discounts change regularly, and the advertised rate isn't always the rate you'll be offered. If you're comparing loan products, focus on the comparison rate, which includes most fees, and check whether the lender charges monthly service fees, annual package fees, or valuation fees. A loan with a slightly higher interest rate but no ongoing fees can cost less over time than a loan with a lower rate and a $395 annual fee.

How LVR and Lenders Mortgage Insurance Affect Loan Options

Your loan to value ratio determines whether you'll pay Lenders Mortgage Insurance and which loan products you can access. Most lenders cap investment loans at 90% LVR, but some restrict certain features if your LVR is above 80%.

If you're borrowing more than 80% of the property's value, you'll pay LMI, which is a one-off cost that can be capitalised into the loan. The higher your LVR, the higher the premium. At 85% LVR, LMI might add $8,000 to $12,000 to your loan. At 90% LVR, that figure can double. Some lenders also restrict interest-only repayments if your LVR is above 80%, which means you'll need a larger deposit if you want to minimise your monthly repayment.

If you're using equity from your Trigg home to fund the deposit on an investment property, your effective LVR depends on the combined value of both properties and the total debt. Lenders assess your borrowing capacity based on your income, existing debts, and the rental income from the new property. Most lenders only count 80% of the rental income when calculating serviceability, which reduces how much you can borrow compared to an owner-occupier loan.

Fixed or Variable After Budget Changes to Negative Gearing

If you purchased an established property in Trigg after 12 May 2026, the changes to negative gearing and capital gains tax from 1 July 2027 affect how you structure your loan. Losses from the property can only be offset against other residential property income, not against your salary, which reduces the tax benefit of holding a negatively geared property.

That shift makes interest-only loans slightly less attractive for investors who were relying on the full deduction to offset wage income. If you're buying a new build, the old rules still apply, and you can choose between the 50% CGT discount or the new inflation-based calculation when you sell. That makes new builds more appealing from a tax perspective, and it's worth comparing investment loan options that suit new construction if that's the direction you're heading.

If your strategy involves holding the property long-term and building equity, a principal and interest loan on a variable rate gives you the flexibility to adjust repayments as rates move and as the tax rules settle. If you're planning to sell within five to seven years, a fixed rate might lock in a known repayment and simplify your budgeting, but you'll lose the ability to make extra repayments or use an offset to reduce interest.
