Fixed Rate Investment Loans: Locking In Certainty

A fixed rate investment loan locks in your interest rate for a set period, typically between one and five years.

For property investors, this means predictable repayments regardless of what the Reserve Bank does with the cash rate. If you're holding multiple properties or relying on rental income to cover your loan repayments, that certainty can make the difference between comfortable cash flow and scrambling to cover shortfalls when rates climb.

How Fixed Rates Work for Investment Properties

When you fix your investment loan interest rate, you're agreeing to pay the same rate for the fixed period, even if variable rates drop. The lender offers you this certainty because they're managing their own interest rate risk. Most lenders offer fixed periods from one to five years, and you'll typically choose between interest only or principal and interest repayments during that time.

Consider an investor who purchases a two-bedroom unit in Kingston for $480,000 with a 20% deposit. They fix their rate on a $384,000 loan for three years on an interest only basis. Their monthly repayments remain identical for the entire fixed period. If variable rates increase by one percentage point during that time, they avoid around $320 in additional monthly repayments while their rate stays locked.

When Fixed Rates Suit Your Investment Strategy

Fixed rates work particularly well when you're managing tight cash flow or holding properties in areas with lower rental yields. If you've purchased in Hobart's inner suburbs where vacancy rates are low but purchase prices are high, knowing exactly what you'll pay each month helps you budget for other property expenses like body corporate fees, insurance, and maintenance.

Investors using negative gearing benefits to reduce their taxable income also find fixed rates helpful. When you know your exact interest expense for the next few years, you can forecast your tax position more accurately. The interest you pay remains a claimable expense whether you fix or stay variable, but the predictability makes financial planning more straightforward.

The Trade-Off: Flexibility and Break Costs

Fixed rate investment loans come with restrictions. Most lenders limit your additional repayments to around $10,000 to $30,000 per year during the fixed period. If you want to pay down your loan faster using rental income or other funds, you'll hit those caps quickly. Some lenders don't allow any extra repayments at all on fixed investment loans.

Break costs apply if you need to exit the loan early. These costs compensate the lender for the interest they'll lose when you leave before the fixed term ends. The calculation depends on the difference between your fixed rate and current wholesale rates, plus how much time remains on your fixed period. In a scenario where you've fixed at 5.8% for five years and rates have since dropped, breaking the loan after two years could cost you several thousand dollars.

If you're considering refinancing to access better features or rates, or if you need to sell the investment property before your fixed term expires, these costs become very real. We regularly see investors who want to leverage equity from one property to purchase another, only to discover their fixed rate loan prevents them from doing so without paying substantial break fees.

Split Rate Loans for Investment Properties

Many investors split their loan between fixed and variable portions. You might fix 60% of your loan amount to protect your core repayments, while keeping 40% variable to maintain flexibility. The variable portion lets you make unlimited additional repayments, access an offset account if the lender offers it, and avoid break costs if you need to refinance or sell.

This approach works particularly well for investors building a portfolio. You protect your cash flow with the fixed portion while maintaining the ability to adjust your strategy through the variable portion. If you purchase another property and want to restructure your loans, the variable portion gives you room to move without triggering break costs on your entire debt.

Tax Considerations and Loan Structure

Your interest payments on an investment property loan remain tax deductible whether you fix or stay variable. However, any break costs you incur when exiting a fixed rate loan early can also be claimed as a tax deduction in the year you pay them. That doesn't make break costs desirable, but it does soften the impact if you need to exit your fixed rate before the term ends.

When you're calculating your rental property loan repayments and projected returns, remember that interest only loans keep your repayments lower during the fixed period, maximising your tax deductions. Principal and interest loans build equity faster but reduce your claimable expenses. The choice depends on whether you're focused on cash flow or paying down debt.

If you're holding investment properties in Tasmania, where stamp duty and other purchase costs are lower than mainland capitals, you might structure multiple fixed rate loans across different properties to spread your risk. We regularly help investors time their fixed rate expiries so they don't all mature in the same year, avoiding the need to refinance several investment property loans simultaneously in a high rate environment.

Choosing Your Fixed Period

Shorter fixed periods give you less certainty but typically come with lower rates and smaller break costs if you need to exit early. Longer fixed periods lock in your rate for more years but can be expensive to break if your circumstances change. Most investors lean toward three-year fixed terms as a middle ground between certainty and flexibility.

Your choice also depends on the rate environment. When interest rates are low or expected to rise, fixing makes more sense. When rates are high or expected to fall, variable loans or shorter fixed periods become more attractive. No one predicts rate movements perfectly, which is why split loans remain popular.
