Variable Rate Investment Loans: The Pros and Cons at Each Stage

Variable rate investment loans give you flexibility when your income changes or you want to add another property to your portfolio.

For community health nurses working across regions or moving between contracts, that flexibility matters more than rate certainty. Your borrowing capacity shifts when you take a remote posting or move into management, and a variable rate loan lets you adjust repayments or refinance without paying break costs. The choice between variable and fixed rates depends on where you are in your career and how much room you need to grow your portfolio.

Why Variable Rates Suit Early Investors

Variable rates let you make extra repayments and access redraw when you need it. When you're in your late 20s or early 30s and buying your first investment property, you want the option to throw extra income at the loan when you pick up agency shifts or overtime, then pull that money back if you need a deposit for a second property. Fixed rates lock you into a set repayment and charge break costs if you refinance early.

In our experience, community health nurses often start with a property close to a regional hospital or in an outer suburb where rental demand stays consistent. The rental income covers most of the loan, and you can claim the interest as a tax deduction. If you bought an established property before 13 May 2026, you can still claim the full loss against your salary under negative gearing rules. For properties bought after that date, losses from 1 July 2027 onward can only be offset against rental income or capital gains from residential property, though you can carry forward any excess to future years.

Managing Portfolio Growth in Your 30s and 40s

A variable rate loan makes it easier to release equity when you want to buy a second property. Consider a community health nurse who bought a unit near a regional centre in her early 30s. Five years later, the property has increased in value and she's paid down the loan. She refinances on a variable rate, accesses the equity as a deposit for a second property, and keeps both loans flexible so she can adjust repayments depending on rental income and her shift patterns.

Using equity release to fund your next deposit means you don't need to save another 10% or 20% from your salary. The variable rate structure lets you refinance without penalty, and you can split your borrowing across multiple properties without locking into fixed terms that expire at different times. If one property has a vacancy or needs maintenance, you can reduce repayments on the other loan temporarily using a redraw facility.

Interest Only Repayments and Cash Flow

Interest only repayments reduce your monthly outgoings and let you hold multiple properties without stretching your income. When you're building a portfolio in your 40s, switching to interest only on your investment loans frees up cash flow to cover holding costs or fund another purchase. You're not paying down the principal, but you're claiming the full interest as a deduction and banking on capital growth over time.

Most lenders offer interest only periods of five years on investment loans, and you can often extend or refinance when that period ends. The trade-off is that your loan balance stays the same, so you're relying on the property to increase in value. Variable rates give you the option to switch back to principal and interest repayments if your income increases or you want to reduce debt before retirement. That flexibility is harder to access on a fixed rate without paying break costs.

Refinancing When Your Income or Strategy Changes

Variable rates let you refinance without penalty when your circumstances change. In your late 40s or early 50s, you might move into a senior role with higher income, reduce your hours, or relocate for a different posting. Investment loan refinancing lets you consolidate multiple loans, negotiate a lower rate, or switch from interest only to principal and interest as you approach retirement.

If you've held properties for more than a decade, you'll likely have significant equity and a stronger borrowing position. Refinancing on a variable rate means you can access that equity without waiting for a fixed term to expire, and you can structure your loans to suit your current income and tax position. Some lenders also offer rate discounts for nurses and healthcare professionals, which can reduce your interest costs across your portfolio.

Planning for Retirement and Debt Reduction

Variable rates give you the flexibility to pay down debt faster when you're within a decade of retirement. Once you stop working full time, rental income needs to cover the loans or you'll need to sell properties to clear debt. Switching to principal and interest repayments in your 50s reduces your loan balance steadily, and making extra repayments when you can accelerates that process.

If you're holding multiple properties, you might choose to sell one and use the proceeds to pay down the others, leaving you with one or two positively geared properties that generate income without a loan attached. The CGT changes from 1 July 2027 mean you'll pay a minimum 30% tax on capital gains for properties bought after Budget night, though gains that accrued before that date are unaffected. For properties you've held since your 30s or 40s, most of the gain will have occurred under the old rules, so the impact is limited.
