Do you know how Fixed Rate Investment Loans change?

Locking in a Fixed Rate on Your First Investment Property

A fixed rate gives you certainty on your interest costs for a set period, typically one to five years. For someone buying their first investment property, this means you know exactly what your repayments will be while you establish rental income and build confidence as an investor.

Consider a buyer in their late twenties who wants to purchase a one-bedroom unit near Noble Park's transport corridor. They're still renting themselves and worried about rate movements affecting their ability to hold the property. A three-year fixed rate on an interest only investment loan locks in the repayment at a level they can manage even during rental vacancies. Over that period, they've built equity and have a clearer picture of their borrowing capacity for a second property. The fixed term gave them breathing room to adjust to property ownership without the pressure of variable rate swings.

Fixed terms do come with restrictions. You usually can't make extra repayments beyond a small annual threshold, and breaking the loan early can trigger significant costs. If you're planning to sell or refinance before the fixed term ends, those break costs can erode any benefit the fixed rate provided. The decision depends on how long you plan to hold the property and whether rate stability is worth the trade-off in flexibility.

Using Fixed Rates to Lock in Serviceability for Portfolio Growth

When you already own one investment property and want to add a second, lenders assess your borrowing capacity based on your total debt position. A fixed rate on your existing investment loan can improve serviceability because some lenders assess fixed loans at the actual rate rather than a higher buffer rate.

In our experience, investors in their mid-thirties often reach this stage. They've built equity in a first property and want to use that equity to fund a deposit on a second. Fixing the rate on the first property can reduce the assessed repayment figure, which may increase how much the lender is willing to advance for the next purchase. This approach works when you're buying within a short timeframe and need every dollar of borrowing capacity to make the numbers work.

That said, this isn't universal across all lenders. Some still assess fixed loans at a buffer rate regardless of the actual fixed rate, so the benefit depends on which lender you're working with. If you're planning a second purchase, it's worth structuring your existing loan with this in mind before you apply.

Balancing Fixed and Variable Rates Across Multiple Properties

Once you own two or more investment properties, splitting your loans between fixed and variable rates can reduce overall risk. A portion of your debt remains stable, while the rest gives you flexibility to make extra repayments or access redraw if you need funds for maintenance or further investment.

Noble Park investors with multiple properties often hold a mix of older units near the station and newer townhouses further out. One property might be on a fixed rate to provide certainty on cash flow, while another is variable to allow lump sum payments from bonuses or rental surpluses. This setup means you're not locked into a single strategy across your entire portfolio, and you can adjust repayments as your income or rental income changes.

The split also matters when interest rates fall. If all your loans are fixed, you miss out on the benefit of lower rates. If they're all variable, you're exposed when rates rise. A 50-50 or 60-40 split gives you a middle ground, though the exact ratio depends on your risk tolerance and how predictable your income is.

Fixed Rates and the 2027 Tax Changes for Established Properties

From 1 July 2027, established residential investment properties purchased after 12 May 2026 will no longer allow full negative gearing deductions against wage income, and the 50% capital gains discount will be replaced with an inflation-based model and a minimum 30% tax on gains. If you're considering a fixed rate on a property purchased after that date, the tax treatment of your holding costs changes.

Negative gearing losses on these properties will only be deductible against rental income or capital gains from residential property, not against your salary. This doesn't make fixed rates less relevant, but it does mean the interest deduction you're locking in will have a narrower application. If your strategy relied on offsetting a high salary with property losses, that benefit is reduced. Fixed rates still give you certainty on repayments, but the tax outcome is different.

Properties purchased before Budget night in May 2026 are grandfathered under the old rules, so existing investors are unaffected on those holdings. If you're adding to your portfolio now, the timing of your purchase and whether the property is new or established will determine which tax rules apply. This is worth discussing with your accountant before deciding on a fixed or variable rate structure.

Fixing Rates When You're Close to Retirement

Investors in their fifties and sixties often shift from growth to income stability. If you're planning to retire within the next five to ten years, fixing the rate on your investment properties can lock in predictable cash flow and reduce the risk of rate rises affecting your retirement budget.

We regularly see this with clients who own two or three properties in areas like Noble Park, Springvale, and Dandenong. They're no longer focused on adding properties but on holding what they have and ensuring rental income covers costs. A five-year fixed rate aligns with their retirement timeline and removes uncertainty around interest rate movements during that period. If they plan to sell one property to clear debt before retiring, they'll need to weigh the fixed term against potential break costs, but for properties they intend to hold long-term, the stability often outweighs the restrictions.

Another consideration at this stage is whether to switch from interest only to principal and interest repayments. Many lenders limit interest only periods as you approach retirement age, and paying down principal reduces your debt position before your income drops. Fixing a principal and interest loan gives you certainty on both the interest and principal components, which makes budgeting through retirement more predictable.

When to Avoid Fixing Your Investment Loan

Fixed rates aren't suitable in every situation. If you're planning to sell the property within the fixed term, break costs can be substantial and may exceed any benefit you gained from rate certainty. If you expect a significant cash injection such as an inheritance or sale of another asset and want the flexibility to pay down the loan quickly, a variable rate is usually more suitable.

Likewise, if you're likely to refinance your investment loan to access equity for another purchase, a fixed rate can create delays and costs. Break costs are calculated based on the difference between your fixed rate and the current wholesale rate, so if rates have fallen since you fixed, the cost to exit can be tens of thousands of dollars. For investors who are actively building their portfolio and need regular access to equity, variable rates or shorter fixed terms are more practical.

Noble Park's proximity to Monash University and the revitalised Noble Park Aquatic Centre has made it a strong rental market, particularly for investors targeting students and young families. If you're holding property in this area with plans to leverage equity as values rise, maintaining flexibility through variable rates may serve you better than locking in a fixed term.

Choosing the Right Fixed Term for Your Stage

The length of your fixed term should match your goals and timeline. A two-year fix gives you short-term certainty without long-term commitment, while a five-year fix is more suited to investors who want maximum stability and aren't planning major changes to their portfolio.

Younger investors often benefit from shorter terms because their circumstances change more frequently, whether through career moves, relationship changes, or shifting investment strategies. Mid-career investors with stable income and a clear plan may prefer longer terms to lock in rates during a period of growth. Those approaching retirement often choose longer terms to align with their transition out of full-time work.

There's no single answer, but the decision should be based on your specific situation rather than market predictions. If you're unsure which term suits your stage of life and your portfolio, speaking with a broker who understands investment loan options across different lenders can clarify which structure aligns with your goals.
