Fixed Rate Investment Loans and What They Mean for You

Fixed rate investment loans lock your interest rate for a set period, typically one to five years. This means your repayments remain unchanged during that term, regardless of whether the Reserve Bank raises or lowers the cash rate.

For property investors in Evatt and surrounding Belconnen suburbs, this certainty becomes particularly relevant when assessing borrowing capacity for units and townhouses where body corporate fees already reduce serviceability margins. Lenders calculate your ability to service debt using either the actual rate plus a buffer or a floor rate, whichever is higher. When you fix, that calculation uses the fixed rate, which can sometimes work in your favour if variable rates have climbed.

How Fixed Terms Affect Rental Income Calculations

Fixed rate periods determine how long you can rely on consistent loan repayments when calculating your net rental return. If you secure a property in Evatt with rental income of $550 per week and fix your loan repayments at $2,400 per month for three years, you know exactly what your cash flow position will be during that period, assuming the property remains tenanted.

This certainty matters when your property investment strategy involves holding multiple properties or releasing equity for portfolio growth. Consider an investor who purchased a two-bedroom unit in Evatt in mid-2023 with a fixed rate for three years on an interest only investment loan. With body corporate fees around $1,200 per quarter and council rates of approximately $450 per quarter, the fixed repayment amount meant they could accurately project their quarterly holding costs and calculate whether negative gearing benefits would offset the shortfall between rental income and expenses.

The outcome depended entirely on their ability to claim expenses including loan interest, body corporate fees, and depreciation on the building and fixtures. The fixed term gave them three years of predictable deductions for tax planning purposes.

Break Costs and Why They Matter for Investors

Break costs apply when you exit a fixed rate loan before the term ends. Lenders calculate this based on the difference between your fixed rate and the current wholesale rate they can achieve by lending that money elsewhere, multiplied by the remaining months on your fixed term.

In our experience, investors underestimate how quickly circumstances change. You might secure a three-year fixed rate with plans to hold the property long-term, then receive an offer to purchase that delivers a significant capital gain within 18 months. If rates have fallen since you fixed, breaking the loan could cost tens of thousands of dollars, which directly impacts your net profit on the sale.

Alternatively, you might want to refinance to access equity for a second purchase. With investment loan refinance options, you would need to weigh the break cost against the benefit of accessing equity at current market valuations. For a property in Evatt where median unit prices have moved from around $480,000 to over $520,000 in recent years, the equity release could justify the break cost if it allows you to secure another deposit and leverage into a second property.

Principal and Interest Versus Interest Only on Fixed Terms

You can fix an investment property loan on either principal and interest or interest only repayment structures. Interest only investment arrangements typically run for one to five years before reverting to principal and interest, and you can fix the rate during that interest only period.

The loan amount you can borrow often differs between these structures. Lenders apply stricter loan to value ratio limits for interest only loans, usually capping them at 80% to 90% LVR depending on your deposit size and the lender's appetite. This affects investor borrowing capacity, particularly in Canberra where Lenders Mortgage Insurance costs become substantial above 80% LVR.

For investors focused on maximising tax deductions and cash flow, fixing on an interest only basis keeps repayments lower during the fixed period, which increases the negative gearing component you can claim. However, you need a clear exit strategy for when the interest only period expires, whether that involves refinancing, selling, or switching to principal and interest repayments at potentially higher prevailing rates.

Split Rate Structures for Property Investors

Some investment loan options allow you to split your loan amount between fixed and variable portions. You might fix 60% of the loan and leave 40% on a variable rate, giving you repayment certainty on the majority while retaining flexibility to make additional repayments or access redraw on the variable portion without break costs.

This structure suits investors in areas like Evatt where vacancy rates remain relatively low, typically under 2%, meaning rental property loan repayments need to continue even during short vacancy periods. The variable portion can function as a buffer where you park surplus rental income during tenanted periods, then draw it down if you experience a gap between tenants.

The split also addresses the reality that investor interest rates often carry a premium over owner-occupier rates, typically 0.20% to 0.40% higher depending on the lender and your LVR. Fixing a portion locks in that premium, but only for part of your debt, reducing your exposure if lender pricing becomes more favourable for investors over time.

What Happens When Your Fixed Term Expires

At the end of your fixed rate term, your loan automatically reverts to the lender's standard variable rate unless you take action. For investment loans, this standard rate is almost always higher than the discounted rates available to new or refinancing customers, sometimes by 1% or more.

Investors often treat fixed rate expiry as a refinancing trigger, comparing their current lender's retention offer against what they can access elsewhere. The difference in rate discount can substantially affect your passive income from the property. On a $450,000 rental property loan, a 0.50% difference in rate translates to approximately $2,250 per year in additional interest costs, which flows directly through to your taxable income calculation via reduced deductible interest.

Canberra's property market, particularly in established suburbs like Evatt where townhouses and units dominate, tends to attract long-term investors rather than flippers. If your property investment strategy involves holding for capital growth and building wealth through property over decades, reviewing your rate at each fixed term expiry becomes a discipline that compounds over time.

If you are weighing fixed versus variable options for your next property purchase or considering whether to refix as your current term ends, the decision depends on your specific circumstances including your equity position, rental income projections, and portfolio goals.
