Investment Loan Features: The Pros and Cons

An investment loan is structured differently from an owner-occupier loan because the purpose and tax treatment differ. The features you select should align with your cash flow position, tax circumstances, and portfolio plans rather than simply matching what you use for your home loan.

Investors in Mandurah and across Australia are currently navigating a changed environment. From 1 July 2027, negative gearing will be quarantined for most residential properties purchased after 12 May 2026, and capital gains tax arrangements will shift to indexation with a minimum 30 per cent rate on real gains. The ability to access equity, manage cash flow through interest-only periods, and structure loans for tax efficiency will matter more as investors look to properties that still qualify for the existing rules or new builds that retain full negative gearing benefits.

Interest-Only Repayments on Investment Property Finance

An interest-only period allows you to pay only the interest charged each month without reducing the loan amount. This lowers your monthly outgoing and can improve cash flow, particularly when rental income does not cover the full cost of holding the property.

Consider an investor who purchases a unit in Mandurah's marina precinct with a loan of $450,000 at a variable interest rate. On principal and interest repayments, the monthly cost might sit around $2,800. On interest-only terms, that drops to approximately $2,100. The difference provides breathing room if the tenant vacates or body corporate levies increase unexpectedly. Interest-only terms typically run for one to five years, after which the loan reverts to principal and interest unless you renegotiate.

The downside is that you build no equity through repayments during the interest-only period. If property values do not rise, your equity position remains static. For investors relying on capital growth to fund further purchases, this can delay portfolio expansion. Interest-only loans also attract a rate premium of around 0.20 to 0.40 percentage points compared to principal and interest products, though this is often justified by the improved cash flow.

Offset Accounts and Redraw Facilities

An offset account linked to your investment loan reduces the interest charged by offsetting your savings balance against the loan amount. A redraw facility allows you to access extra repayments you have made above the minimum required.

For investment purposes, offset accounts are generally preferred over redraw. Funds held in offset remain your cash and can be withdrawn without affecting the deductibility of interest on the investment loan. Redraw can create complications if you have mixed the loan purpose, such as borrowing for investment and then redrawing funds for private use. The ATO may disallow a portion of your interest deduction in that scenario.

Not all lenders offer offset on investment products, and some charge an annual fee of $200 to $400 for the feature. If you do not maintain a meaningful balance in the offset account, the fee can outweigh the interest saved. As an example, offsetting $10,000 on a loan at 6.5 per cent saves around $650 in interest annually. If the offset fee is $300, the net benefit is $350. If your offset balance averages $3,000, the fee exceeds the saving.

Fixed Rate Versus Variable Rate Investment Loan Products

A fixed rate locks your interest rate for a set period, typically one to five years. A variable rate moves with the lender's pricing decisions and generally provides access to offset accounts and the ability to make extra repayments without penalty.

Investors who fix a portion of their loan gain certainty over cash flow for the fixed period. This can be useful if rental income is tight and an interest rate rise would push the property into deeper negative territory. The cost is reduced flexibility. Most fixed rate products limit extra repayments to $10,000 to $30,000 per year and charge break costs if you refinance, sell the property, or repay the loan early during the fixed term. Fixed rate expiry can also catch investors off guard if they do not review their loan before the fixed period ends and the rate reverts to a higher variable rate.

Variable rate products allow unlimited extra repayments and typically offer offset, redraw, and the ability to refinance without penalty. For investors planning to access equity within a few years to fund the next purchase, a variable rate provides the flexibility required. Some lenders also offer rate discounts on variable products for investors with multiple properties or larger loan amounts, which can bring the ongoing rate below the equivalent fixed rate.

Loan to Value Ratio and Lenders Mortgage Insurance

The loan to value ratio is the loan amount expressed as a percentage of the property's value. Most lenders cap investment loans at 90 per cent LVR, and many investors find better rates and terms by keeping the LVR at 80 per cent or below.

Borrowing above 80 per cent LVR triggers Lenders Mortgage Insurance, a one-off premium that protects the lender if you default. LMI on an investment property is capitalised into the loan and is not tax deductible. On a $500,000 property with a 10 per cent deposit, LMI could add $15,000 to $20,000 to your loan amount. At 80 per cent LVR, LMI does not apply.

Some lenders also tighten serviceability for investment loans above 80 per cent LVR, applying a higher interest rate buffer or reducing the rental income they include in their assessment. Keeping your LVR at or below 80 per cent provides access to a wider range of lenders, lower rates, and the ability to negotiate on fees and features.

Accessing Equity for Portfolio Growth

Equity in an existing property can be used as security to fund the deposit on your next investment without selling. This is commonly structured as a top-up on your existing loan or a separate split secured against the same property.

In our experience, investors who plan to use equity within 12 to 24 months should avoid fixing their loan or choose a small fixed portion only. Accessing equity during a fixed rate period can trigger break costs, which in some cases exceed the benefit of the lower fixed rate. A variable rate loan with offset provides the flexibility to increase the loan amount when the next opportunity arises without penalty.

The amount of equity you can access is limited by the lender's maximum LVR across your portfolio. If you own your home and one investment property, the lender will assess the combined debt against the combined value of both properties. Releasing equity that pushes your overall LVR above 80 per cent will trigger LMI on the additional borrowing. For investors building a portfolio, maintaining buffers below 80 per cent LVR on each property provides the capacity to leverage equity efficiently.

Rate Discounts and Loan Amount Thresholds

Some lenders offer tiered pricing on investment loans, with lower interest rates applying once the loan amount exceeds a certain threshold. A discount of 0.10 to 0.30 percentage points is common for loans above $500,000 or $750,000, depending on the lender's policy.

If you are close to a threshold, it may be worth structuring your borrowing to exceed it. However, borrowing more than required simply to access a rate discount is rarely justified. The additional interest on the extra borrowing usually exceeds the saving from the discount.

Investors with multiple properties financed through the same lender may also qualify for portfolio discounts. Consolidating your lending with one institution can provide leverage during rate negotiations, though it also increases concentration risk if that lender tightens policy or reduces appetite for investment lending.

Splitting Your Investment Loan

Loan splits allow you to divide your borrowing into separate accounts, each with different features or rates. A common structure is to fix a portion for rate certainty and leave the remainder on a variable rate with offset for flexibility.

Splitting also allows you to separate interest-only and principal and interest components. For example, you might keep 70 per cent of the loan on interest-only terms to maximise tax deductions and manage cash flow, while placing 30 per cent on principal and interest to gradually reduce debt as the property appreciates. This structure provides a balance between current tax benefits and long-term equity growth.

Each split is treated as a separate loan for feature and rate purposes, though most lenders do not charge additional application or ongoing fees for splits. The complexity comes at review time. Each split may have a different maturity date for fixed terms or interest-only periods, requiring active management to avoid unintended rate increases or feature changes.

Construction and Renovation Features for Investors

If you are building a new investment property or undertaking a substantial renovation, the loan will typically include progressive drawdowns and capitalised interest during construction. Interest is charged only on the amount drawn, and most lenders allow you to capitalise that interest rather than service it monthly.

Capitalising interest increases your loan balance but preserves cash flow during the construction phase when the property is not generating rental income. Once construction completes, the loan converts to a standard investment loan and you begin making regular repayments. If you have structured the loan as interest-only, the repayment amount can remain manageable even with the higher post-construction loan balance.

Construction loans for investment purposes are assessed on projected rental income rather than current income, and the lender will require a valuation as complete or a market valuation after practical completion before releasing the final drawdown. This can delay settlement if defects or compliance issues arise, so allowing a buffer between practical completion and your expected rental start date is prudent.

Portability and Discharge Flexibility

Portability allows you to transfer your loan to a different property if you sell the current investment and purchase another. Not all lenders offer this feature, and those that do often require the new property to meet their current lending criteria.

For investors who plan to sell and reinvest frequently, portability can save on discharge and application fees. However, if your existing loan rate is uncompetitive or the lender's policy has tightened since you first borrowed, portability may lock you into unfavourable terms. In most cases, refinancing to a new lender when you purchase the next property provides an opportunity to negotiate a lower rate and better features.

Discharge fees on investment loans typically range from $300 to $500, though some lenders waive this if you refinance a portion of your portfolio to them. If you are planning to sell within the next 12 months, checking your lender's discharge terms and any penalties for early repayment is worthwhile.

The features you select for an investment loan should support your immediate cash flow requirements and your longer-term portfolio strategy. Loans structured with flexibility, such as variable rates with offset and the ability to access equity without penalty, provide the greatest range of options as your circumstances and the regulatory environment continue to shift.
