Understanding the Basics of Investment Loan Features

Investment loan features determine how much capital you can access, how you structure repayments, and which tax deductions you can claim.

For investors in Kew, where established properties command premium prices and rental yields hover around 3%, the loan features you select affect both cash flow and long-term wealth accumulation. Choosing between interest-only and principal-and-interest repayments, for instance, changes your monthly outgoings by several hundred dollars while influencing your equity position years down the line. Similarly, the option to redraw funds or access an offset account shapes how you manage surplus cash across multiple properties.

The Budget changes announced in May also mean that investors who purchased established properties after 12 May 2026 will face different tax treatment from 1 July 2027. Understanding which loan features support your investment strategy becomes even more important when deductions are restricted to rental income and capital gains from residential property.

Interest-Only Repayments and Cash Flow Management

Interest-only repayments reduce your monthly loan cost by excluding principal repayments for a set period, usually between one and five years. You pay only the interest charged on the outstanding loan amount, which lowers your immediate cash requirement and maximises your ability to claim interest as a tax-deductible expense.

Consider an investor who borrows to purchase an established apartment in one of Kew's inter-war blocks. Rental income covers most but not all of the loan cost. By selecting interest-only repayments during the initial holding period, the investor preserves cash flow and directs surplus funds toward a second deposit rather than reducing debt on the first property. Once the interest-only period expires, the loan reverts to principal-and-interest repayments unless the investor negotiates an extension or refinances.

Interest-only periods suit investors focused on portfolio growth rather than debt reduction. However, lenders typically require a lower loan-to-value ratio for interest-only loans compared to principal-and-interest loans, meaning you may need a larger deposit or more equity to access this feature.

Offset Accounts Versus Redraw Facilities

An offset account is a transaction account linked to your investment loan. The balance in the offset account reduces the loan balance on which interest is calculated, lowering your interest cost without making additional repayments. A redraw facility allows you to withdraw any extra repayments you have made above the minimum required amount.

For investors, offset accounts offer a clearer tax position. Funds held in an offset account remain separate from the loan, so withdrawing money does not affect the deductibility of your loan interest. If you use a redraw facility and withdraw funds for personal use, the ATO may disallow a portion of your interest deductions because the loan purpose has changed.

Investors holding multiple properties often consolidate surplus rental income in an offset account linked to their highest-rate loan. This strategy reduces interest costs while maintaining access to cash for future deposits, repairs, or settlement costs. Some lenders charge a monthly fee for offset accounts, so compare the interest saved against the account fee before selecting this feature.

Fixed Rate Versus Variable Rate for Investment Property

A fixed interest rate locks your rate for a set term, typically between one and five years, protecting you from rate increases during that period. A variable interest rate fluctuates with market conditions, which means your repayments can rise or fall depending on the Reserve Bank's cash rate decisions and lender pricing.

Investors using interest-only repayments often prefer variable rates because fixed-rate loans rarely offer interest-only terms longer than three years, and switching from fixed to variable mid-term can incur break costs. Variable rates also provide access to offset accounts and unlimited additional repayments, which fixed-rate products typically restrict.

Some investors split their loan between fixed and variable portions. This approach provides partial protection from rate increases while retaining the flexibility to make extra repayments or use an offset account on the variable portion. If you are considering this structure, review the refinancing options available once the fixed term expires to ensure you are not locked into an uncompetitive rate.

Loan-to-Value Ratio and Lenders Mortgage Insurance

Your loan-to-value ratio (LVR) is the loan amount expressed as a percentage of the property's value. Lenders typically charge Lenders Mortgage Insurance (LMI) when your LVR exceeds 80%, and the premium increases as your LVR rises. For investment loans, some lenders cap the LVR at 90% or lower, depending on the property type and your financial position.

LMI premiums for investment loans are generally higher than for owner-occupied loans at the same LVR. The premium is usually added to the loan amount rather than paid upfront, which increases your total debt and the interest you pay over the loan term. If you are leveraging equity from an existing property to fund the deposit on your investment property, structuring the loan to stay at or below 80% LVR avoids LMI entirely.

Some lenders offer LMI waivers for certain professions or portfolio structures, so discuss your options with a broker who can access a broad panel of lenders.

Line of Credit and Equity Access

A line of credit functions like a pre-approved loan limit secured against property. You can draw down funds as needed, up to the approved limit, and interest is charged only on the amount you use. Investors use lines of credit to access equity for deposits, renovations, or settlement costs without applying for a new loan each time.

Lines of credit suit experienced investors managing multiple properties or those undertaking staged developments. However, lenders assess lines of credit at higher serviceability buffers than standard investment loans, meaning your borrowing capacity may be lower. Interest rates on lines of credit are also typically higher than standard variable rates, and most lenders require principal-and-interest repayments or quarterly interest payments to reduce the outstanding balance over time.

If you plan to use equity from your Kew property to fund additional purchases in surrounding suburbs like Bulleen or Templestowe, a line of credit offers flexibility without the need to refinance your entire loan each time you require funds.

Portability and Loan Flexibility

Portability allows you to transfer your existing loan to a new property without discharging and reapplying. This feature is useful if you sell your investment property and purchase another within a short timeframe, as it avoids discharge fees, application fees, and the time required to assess a new loan.

Not all lenders offer portability, and those that do may impose conditions such as maintaining the same loan amount or purchasing within a specific timeframe. If you anticipate selling and reinvesting within a few years, confirm whether your lender supports portability before settling on your initial loan.

Flexibility also extends to repayment options. Some lenders allow you to switch between interest-only and principal-and-interest repayments, or adjust your repayment frequency, without refinancing. Others permit you to pause repayments temporarily in the event of extended vacancy or financial hardship, though these features are typically subject to lender approval and may incur fees.

How Budget Changes Affect Investment Loan Structuring

If you purchased an established residential property in Kew after 12 May 2026, negative gearing deductions from 1 July 2027 will be limited to offsetting rental income or capital gains from residential property. Losses cannot be claimed against salary or other income sources, though they can be carried forward to future years.

This change influences how investors structure their loans. Maximising deductible interest through interest-only repayments remains relevant, but the cash flow benefit is reduced if you cannot offset the loss against wage income. Investors may prioritise properties with higher rental yields or shorter holding periods to realise capital gains while cost base indexation applies.

New builds purchased after Budget night retain access to the 50% capital gains discount, and investors can choose between the discount or cost base indexation when disposing of the property. If you are comparing established and new properties, factor in both the upfront cost difference and the long-term tax treatment when calculating returns.

For investors holding properties acquired before Budget night, the existing negative gearing rules and 50% CGT discount continue to apply. If you are considering refinancing an existing investment property, discuss with your broker whether restructuring your loan affects the grandfathering provisions or your ability to claim interest deductions. Additional guidance on loan structuring is available through a loan health check.

Vacancy Provisions and Interest Rate Discounts

Lenders assess your ability to service an investment loan based on rental income, but most apply a vacancy rate or discount to the rental amount to account for periods when the property is untenanted. The standard vacancy discount ranges from 20% to 30%, meaning the lender assumes you will receive only 70% to 80% of the advertised rent when calculating serviceability.

If you are purchasing in Kew, where tenant demand from young professionals and downsizers is relatively stable, a lower vacancy rate may apply depending on the lender's risk assessment. However, lenders also assess your other income sources and existing debts, so rental income alone rarely determines your borrowing capacity.

Interest rate discounts vary by lender, loan amount, and LVR. Larger loan amounts and lower LVRs typically attract greater discounts, while interest-only loans or loans at higher LVRs may receive smaller discounts or be priced at a premium to the lender's standard variable rate. Reviewing your rate annually and comparing it against current market offers ensures you are not paying more than necessary, particularly if your LVR has decreased due to property value growth or principal repayments.
