Top tips to use variable rate investor loans wisely

Variable rate loans give property investors flexibility to adapt, overpay and refinance without penalty, but only when the loan structure fits the strategy.

A variable rate loan lets you change direction when circumstances shift.

For investors in The Basin, that flexibility matters. The local rental market is steady, but buying another property in two years or refinancing to pull equity out requires a loan that moves with you. Variable rates suit investors who want ongoing control, not a fixed commitment that locks them in.

Why variable rates suit most property investors

Variable rates adjust with the market, which means your repayments can rise or fall depending on what the Reserve Bank does. More importantly, you can make extra repayments, redraw funds, and refinance without facing break costs. That access is what makes variable loans the default choice for investors building a portfolio.

Consider an investor who bought a unit in The Basin and held it for three years on a variable rate, interest-only loan. When the property value increased, they refinanced to release equity and used that to fund the deposit on a second property in Boronia. The variable structure allowed the refinance without penalty, and the interest-only term kept repayments lower while rental income covered most of the loan cost.

In our experience, investors who plan to buy another property within five years or want the option to pay down the loan early are better served by a variable rate. Fixed rates remove flexibility and charge you to exit early, which conflicts with most long-term property strategies.

How offset accounts reduce taxable income

An offset account linked to your investment loan reduces the interest charged without changing the loan balance. Every dollar sitting in the offset reduces the amount of interest you pay that month, which directly lowers your claimable deduction. That sounds like a disadvantage, but it gives you control over how much interest you pay and when.

If you hold surplus cash from rental income or other sources, parking it in an offset account reduces your interest bill. The interest saved is effectively tax-free income because you are not paying tax on it, and you can pull the cash out anytime without refinancing or affecting the loan. For investors in The Basin holding multiple properties, an offset account linked to the investment loan with the highest balance delivers the biggest saving.

Some lenders allow multiple offset accounts linked to one loan, which lets you split funds for different purposes while still reducing the interest on the entire loan balance. That structure works for investors managing rental income, tax payments and future deposits across several properties.

Interest-only terms and cashflow management

Interest-only repayments are lower than principal and interest because you are only covering the interest portion each month. For the first few years of holding an investment property, that lower repayment often makes the difference between positive and negative cashflow, especially if the rental yield is modest.

In The Basin, median rents sit around $400 to $450 per week for a three-bedroom house, depending on condition and location near the Dandenong Ranges. At that income level, an interest-only loan keeps the monthly repayment low enough that rental income covers most or all of the cost, leaving you with a small shortfall rather than a large one.

Interest-only terms typically run for one to five years, after which the loan converts to principal and interest unless you negotiate an extension or refinance. That conversion increases your repayment significantly, so planning ahead is necessary. Some investors refinance before the interest-only period ends to secure another interest-only term with a different lender, maintaining the lower repayment structure while the property continues to appreciate.

Rate discounts and how lenders price investor loans

Lenders charge investors a higher interest rate than owner-occupiers because the perceived risk is higher. The rate you are offered depends on the loan amount, your deposit size, whether the loan is interest-only or principal and interest, and the lender's appetite for investor lending at that time.

A variable rate investor loan with a 20 per cent deposit will typically attract a rate discount from the lender's standard variable rate. If you are borrowing at 80 per cent loan to value ratio (LVR) or less, most lenders view that as lower risk and price accordingly. Borrowing above 80 per cent LVR usually triggers Lenders Mortgage Insurance (LMI) and a higher rate, though some lenders cap LMI at 90 per cent LVR for investors.

Rate discounts also depend on loan size. Borrowing above $500,000 or $750,000 often unlocks a larger discount because the lender earns more from the loan. For investors in The Basin looking to refinance or add a second property, consolidating loans with one lender or increasing the total loan amount can sometimes improve the rate offered.

Refinancing to access equity for your next purchase

Refinancing an investment property lets you access equity without selling. If your property has increased in value and you have paid down the loan, the difference between the current value and what you owe is usable equity. Lenders will typically let you borrow up to 80 per cent of the property's value without LMI, which means you can pull equity out and use it as a deposit for another property.

As an example, an investor bought in The Basin several years ago and the property is now valued higher. They owe less than 60 per cent of the current value. By refinancing to 80 per cent LVR, they release enough equity to cover a 10 per cent deposit and settlement costs on a second property in Montrose. The refinance took around four weeks, and the variable rate structure meant no penalty for exiting the existing loan.

This approach works when you have a clear plan for the equity and the rental income from the first property covers the higher loan repayment after refinancing. Refinancing to access equity is one of the most common ways investors build a portfolio across Melbourne's eastern suburbs, and the variable rate structure makes it possible without delay or cost.

What changes to negative gearing mean for variable rate loans

From 1 July 2027, negative gearing on established properties purchased after 12 May 2026 will be restricted. Losses on those properties will only be deductible against rental income or capital gains from residential property, not your salary or other income. Losses that cannot be claimed in a given year carry forward.

For investors holding properties on variable rate loans, the loan structure does not change, but the tax treatment of the interest does. If you bought an investment property in The Basin before 12 May 2026, you retain full negative gearing until you sell. If you bought after that date, your ability to offset losses against other income disappears, which changes the cashflow equation.

Variable rate loans still offer the flexibility to refinance, overpay or switch to principal and interest repayments, but the tax benefit of holding a negatively geared property is now limited to new builds purchased after the cut-off date. Investors planning to buy another property should consider whether a new build in a different suburb delivers both the tax benefit and the capital growth they need, or whether an established property still makes sense without full negative gearing.

Holding costs and vacancy allowances in The Basin

Investors in The Basin should factor in body corporate fees if buying a unit, council rates, insurance, and occasional vacancy periods when calculating whether a variable rate loan fits their cashflow. Vacancy rates in the Dandenong Ranges area are generally low, but a property can sit empty for four to six weeks between tenants, and that gap needs covering.

A variable rate loan with an offset account lets you hold a buffer in the offset to cover those holding costs without affecting your loan balance. If the property is vacant, you can draw from the offset to cover the repayment and then rebuild the buffer once a new tenant is in place. That flexibility is one reason variable rates suit investors who want control over their cashflow rather than a fixed repayment they cannot adjust.

Some investors hold three to six months of repayments in their offset account as a contingency, which reduces the interest charged and gives them breathing room if rental income drops temporarily. That approach works particularly well in The Basin, where properties near the town centre and schools rent consistently, but those further into the hills can take longer to fill.

Frequently Asked Questions

Why do most property investors choose variable rate loans?

Variable rate loans let you make extra repayments, redraw funds, and refinance without break costs. That flexibility suits investors who plan to buy another property, release equity, or adjust their loan structure as circumstances change.

How does an offset account work with an investment loan?

An offset account reduces the interest charged on your loan without changing the loan balance. Every dollar in the offset lowers your monthly interest bill, and you can withdraw the funds anytime without refinancing or affecting the loan.

What happens when an interest-only period ends?

The loan converts to principal and interest, which increases your repayment significantly. Many investors refinance before the interest-only term ends to secure another interest-only period with a different lender and maintain lower repayments.

Can I refinance an investment property to access equity?

Yes. If your property has increased in value and you have paid down the loan, you can refinance to release equity and use it as a deposit for another property. Variable rate loans allow this without penalty, and most lenders lend up to 80 per cent LVR without requiring Lenders Mortgage Insurance.

How do the proposed negative gearing changes affect variable rate loans?

The loan structure does not change, but the tax treatment does. Properties bought after 12 May 2026 will only allow losses to be claimed against rental income or residential capital gains, not other income. Variable rate loans still offer flexibility to refinance or adjust repayments regardless of the tax changes.
