If you are a single parent thinking about a fixed rate on an investment loan, the main thing to weigh up is certainty against flexibility. A fixed rate locks in your repayment for a set period, but it can limit what you do with the loan during that time.

After a separation, your budget has probably been rebuilt from scratch. A repayment that does not move can be a relief. It can also become a problem if your life changes before the fixed term ends. Let's walk through how it works so you can decide with a clear head.

What Is a Fixed Rate Investment Loan?

A fixed rate investment loan holds your interest rate at one level for an agreed period, so your repayment stays the same during that time. When the period ends, the loan generally moves to another rate unless you choose a new fixed term. Our page on fixed rate expiry covers what to plan for at that point.

The main appeal is predictability. If you are covering school costs, childcare and a rental property on one income, knowing the repayment can make budgeting less stressful.

Fixed Rate Features and Trade-Offs to Check Before You Sign

The features attached to a fixed rate differ between lenders, so you need to ask about each one before you commit. Rules around offset accounts, extra repayments, redraw and break costs are set by each lender, not by government.

Here are the questions worth asking:

  • Can I make extra repayments, and is there a cap?
  • Can I attach an offset account to the fixed portion?
  • What happens if I want to sell or refinance before the term ends?
  • Can I split the loan into fixed and variable parts?

The main trade-off is that leaving a fixed loan early may trigger break costs, and the way those are calculated varies between lenders. If there is any chance you will sell the property or restructure your finances soon, that risk matters more than a steady repayment.

Fixed Rate or Variable Rate: Which Suits a Single Income?

A fixed rate suits you if certainty matters most. A variable rate suits you if you want flexibility, such as extra repayments or a refinance. Neither one is right for everyone, and the rate you are offered varies by lender and by loan features and circumstances, such as LVR.

A split loan sits between the two. Part of the balance is fixed and part is variable. The trade-off is that you get a partial version of each benefit, and the features on each portion may differ. Ask your broker to confirm what each portion allows. Our page on getting a lower interest rate explains how rate discounts can be negotiated.

How Do Fixed Repayments Look in Real Numbers?

To see the effect of the loan structure, compare interest-only and principal and interest repayments on the same loan. As an illustration only, take a $500,000 loan at 6.75% p.a. over 30 years.

Interest-only repayments would be about $2,812 a month ($500,000 x 6.75% / 12). Principal and interest repayments over 30 years would be about $3,243 a month.

If the loan had a 5-year interest-only period first, the later principal and interest repayments would be calculated over the remaining 25 years. At the same illustrative rate that comes to about $3,455 a month. The lower early repayment is real, but the balance has not reduced, and the later repayment is higher. Lenders also assess interest-only loans on the shorter remaining term, so interest-only does not lift how much you can borrow.

These figures are for illustration only. Use a repayment calculator with your own numbers and speak to a broker. Our interest only loans page has more on how that structure works.

How Much Can You Borrow After Divorce?

Your borrowing amount depends on your income, your debts, your living costs and the lender's rules. Banks must test whether you could still afford the loan at a rate at least 3.0 percentage points above the loan rate, as set by the Australian Prudential Regulation Authority.

Lenders count only part of expected rental income. APRA's guidance suggests no more than 80 per cent of expected rent is counted, to allow for vacant periods. You can read more about borrowing capacity before you speak to anyone.

A Scenario: Fixing Part of the Loan After a Settlement

A split fixed and variable loan can balance certainty with flexibility. Consider a single parent who keeps an investment property after a property settlement and needs to refinance it into their own name.

They work part-time and want a predictable repayment, but they also expect a bonus payment next year that they would like to put against the loan. Their broker suggests fixing about half the loan and leaving the rest variable. The fixed half gives them a repayment they can plan around. The variable half lets them pay down extra without penalty, subject to the lender's terms.

The outcome is a repayment that is partly steady and partly adjustable. The trade-off is that the variable half rises if rates rise, and the fixed half could carry break costs if they sell early. Our guide to investment loan refinancing explains how the process works.

What Tax Rules Apply to Investment Loan Interest?

Interest on a loan used to buy or hold a rental property is generally deductible to the extent the property is rented or available for rent. Only the interest part of a repayment qualifies, not the principal.

The negative gearing rules have also changed. Net rental losses on established residential properties bought after 7:30pm AEST on 12 May 2026 can only be offset against other residential property income from the 2027-28 income year. Properties held at that time, and eligible new builds, are treated differently. Tax outcomes depend on your situation, so speak to your accountant before you decide.

Planning Your Investment Loan Around Your New Life

The right loan structure is one that still works if your income or family situation shifts. A broker who understands separation can help you compare lenders across Australia and match features to your goals. If you are weighing up your first purchase, see buying your first investment property.

Frequently Asked Questions

What is a fixed rate investment loan?

It is an investment loan where the interest rate stays the same for an agreed period, so your repayment does not change. After that period the loan generally moves to another rate unless you fix again.

Can I leave a fixed rate investment loan early?

You can, but break costs may apply if you sell or refinance before the term ends. How these are calculated depends on your lender, so ask before signing.

Does interest-only increase how much I can borrow?

No. Lenders assess interest-only loans on principal and interest repayments over the shorter remaining term, so it does not lift your borrowing amount.

Is investment loan interest tax deductible?

Interest on a loan used for a rental property is generally deductible to the extent the property is rented or available for rent. The principal part of a repayment is not. Speak to your accountant about your situation.
