Investment Loans & Fixed Rate Terms: What Dentists Need

Fixed rate terms on investment loans usually lock you in for one to five years, with three years being the most common choice for dentists building a property portfolio.

The decision matters because it determines how long your repayments stay predictable, how much flexibility you retain to access equity or refinance, and whether you'll face break costs if your circumstances change. For dentists who often have irregular income patterns or plans to expand their practice, the wrong fixed term can create constraints that outweigh the initial appeal of rate certainty.

Why Fixed Rate Terms Appeal to Dental Professionals

Fixed terms give you certainty over your investment property repayments for a defined period. That certainty is useful when you're managing cash flow across both your practice and personal finances, particularly if you've recently bought into a partnership or opened your own clinic.

Consider a periodontist who purchases a two-bedroom apartment as an investment property while also taking on a $400,000 equipment loan for their practice. Locking in a fixed rate on the investment loan means one less variable in their monthly budget while they stabilise practice revenue. The fixed term provides breathing room during the period when practice income might fluctuate.

The downside is inflexibility. If you want to access equity from that investment property to fund a second purchase or redirect funds back into your practice, you'll likely face break costs during the fixed period. Those costs can run into thousands of dollars depending on how much rates have moved since you locked in.

Choosing Between One, Three, or Five Year Fixed Terms

Shorter fixed terms give you more flexibility to refinance or restructure. Longer terms extend your rate certainty but increase the risk that your circumstances will change before the term ends.

A one-year fixed term suits dentists who expect a significant change in their financial position soon, such as a practice sale, partnership adjustment, or plans to purchase another investment property within the next 18 months. You get some short-term stability without committing to a long period where you can't easily adjust your loan structure.

Three-year fixed terms are the middle ground. They provide enough certainty to plan around but don't lock you in for so long that your strategy becomes outdated. If you're planning to hold the property for the medium term and don't foresee major changes to your practice or portfolio, this term often makes sense.

Five-year fixed terms suit dentists with very stable income who are confident they won't need to access equity or change their loan structure for at least that period. The risk is that property values might increase significantly during that time, and you won't be able to leverage that equity without paying break costs. Given how much can change in a dental career over five years, this term tends to suit older practitioners closer to retirement rather than those in their growth phase.

How Fixed Terms Interact With Investment Loan Features

Most fixed rate investment loans don't allow offset accounts, and many restrict additional repayments to a capped amount per year, often around $10,000 to $30,000 depending on the lender. That limitation can frustrate dentists who have variable income and want the flexibility to park surplus funds against their loan when they have a strong earning period.

If you've just sold a practice or received a distribution from a partnership and want to reduce your investment loan balance, you may not be able to do so without triggering break costs. Some lenders allow you to split your loan between fixed and variable portions, which gives you the option to make extra repayments on the variable portion while keeping rate certainty on the fixed portion.

Interest-only repayments are available on fixed rate investment loans, and many dentists use this structure to maximise tax deductions and preserve cash flow for other investments. The fixed term doesn't change whether you can structure the loan as interest-only, but it does determine how long that structure remains in place before you need to either refinance or revert to principal and interest repayments.

Fixed Rate Break Costs and When They Apply

Break costs arise when you exit a fixed rate loan before the term ends. They compensate the lender for the difference between the rate they locked in for you and the rate they can now lend that money at.

If rates have fallen since you fixed, break costs can be substantial. If rates have risen, break costs are often minimal or nil. That means fixing when rates are at or near a peak is less risky from a break cost perspective than fixing when rates are low and likely to rise.

For dentists, break costs most commonly arise when refinancing to access equity for another property purchase, when selling the investment property, or when consolidating debt after a practice acquisition. Many dentists underestimate how often their circumstances change within a three to five year period, particularly if they're in their 30s or early 40s and still actively growing their wealth.

Some lenders allow portability, which means you can transfer your fixed rate loan to a new property if you sell and buy within a short window. Not all lenders offer this, and the conditions vary, so it's worth understanding before you commit to a fixed term.

Structuring Around the 2027 Changes to Investment Property Taxation

From 1 July 2027, established residential properties purchased after 12 May 2026 will no longer allow full negative gearing deductions against your other income. Losses will only be deductible against other rental income or capital gains from residential property. The capital gains tax discount is also changing to an inflation-based model with a minimum 30% tax on gains.

If you're considering locking in a fixed rate now on an investment property purchased before those changes take effect, the fixed term might carry you through the transition period with predictable repayments while you assess how the new tax treatment affects your holding strategy. On the other hand, if you're planning to purchase an established property after the changes take effect, you may want shorter fixed terms to retain flexibility as you adjust your approach.

New builds remain eligible for the existing 50% CGT discount and full negative gearing, which may influence whether you choose an established property or a new build, and by extension, how long you're willing to lock in your rate. If you're buying a new build with a longer settlement period, you might prefer a variable rate initially so you're not paying interest during construction without the ability to adjust your loan structure.

When Variable Rates Make More Sense Than Fixed Terms

Variable rates suit dentists who value flexibility over certainty. You can make unlimited additional repayments, access offset accounts to reduce interest while keeping funds available, and refinance or restructure without break costs.

If you're planning to expand your property portfolio quickly or expect significant changes in your practice income, a variable rate gives you room to move. You can also split your loan, fixing part for stability and keeping part variable for flexibility. Many dentists find this approach provides the right balance, particularly when they're managing both practice debt and investment debt simultaneously.

Variable rates also make sense if you expect rates to fall in the near term. Fixing at a rate that's higher than where you think the market is heading locks in a cost that you could have avoided. Given the recent budget changes and their potential impact on property demand, rate movements are harder to predict, which makes flexibility more valuable.

Matching Fixed Terms to Your Investment Timeline

Your fixed term should align with how long you plan to hold the property and when you expect to need access to equity. If you're buying an investment property now with the intention of purchasing a principal place of residence in two years, a one or two year fixed term makes more sense than a five year term.

If you're building a long-term portfolio and this property is an early acquisition in a multi-property strategy, you'll likely want shorter fixed terms or a variable rate so you can access equity as the property appreciates. Dentists who are further along in their careers and focused on consolidating rather than expanding might prefer longer fixed terms for stability as they approach retirement.

The key is not to lock in a term that extends beyond your planned holding period or the point at which you'll need to refinance. Many dentists fix for three years because it sounds sensible, but then find themselves paying break costs 18 months later when they want to leverage equity for their next purchase.
