Keeping your first home and renting it out when you buy the next one is one of the most common ways Australians become property investors. It can also be one of the most expensive to get wrong, because the loan, the tax position and the lender’s view of your finances all change the day the property stops being your home. Sorting out the structure before you move out is far easier than fixing it afterwards.
Your Lender Needs to Know
Most home loan contracts require you to tell the lender if the property is no longer owner-occupied. Lenders price investment loans differently, so the loan may be moved onto an investor rate, which is typically higher than the owner-occupier rate on the same product.
Some borrowers are tempted to leave the loan as it is. That risks breaching the loan contract, and it can create problems later when the lender reviews the account or when you apply for further lending and the property is shown as rented. A conversation with your lender or broker before the move gives you a chance to negotiate the investor pricing rather than having it imposed.
Why Loan Structure Matters for Tax
Whether interest on a loan is tax deductible generally depends on what the borrowed money was used for. The property that secures the loan does not decide it. A loan used to buy the property you now rent out can remain deductible, but anything redrawn from that loan for personal spending, such as a car or a renovation on your new home, can mix private and investment purposes in the one account.
This is where offset accounts and redraw facilities behave very differently. Money sitting in an offset account is your own savings, so taking it out does not add to the loan balance. Money taken out of redraw is generally treated as new borrowing for whatever it is spent on. Borrowers who plan to rent out their home one day often find that holding savings in an offset rather than paying down the loan keeps more flexibility, but the tax treatment is complex and a registered tax agent or accountant is best placed to advise on your circumstances.
Can You Switch the Investment Loan to Interest-Only?
Often, yes, subject to the lender’s approval. Interest-only repayments can free up cash flow while you pay down the debt on your new home, but they require a fresh application, the lender will assess whether you can afford the higher repayments when the interest-only period ends, and investor interest-only rates are usually higher again.
How Lenders Assess You for the Next Purchase
When you apply for the loan on your new home, the lender will count the rent from your former home as income, but usually only around 75% to 80% of it, and will assess the existing loan repayments at a buffered rate. Our guide to how lenders assess rental income explains the shading in more detail.
The result is that two mortgages, one income stream and a shaded rental figure can produce less borrowing capacity than many people expect. Running the numbers early shows whether the plan works on the lender’s figures as well as your own budget.
Avoid Linking the Two Properties by Default
If you use equity in your first home to fund the deposit on the second, some lenders will propose securing both loans against both properties. This is known as cross-collateralisation, and it can make selling or refinancing one property more complicated later.
A standalone structure, where each property secures only its own loan, usually involves separate loan accounts and sometimes a separate equity release loan for the deposit. It can cost a little more to set up but keeps the two properties independent of each other.
Other Things That Change When You Move Out
If you bought with a government guarantee, such as the 5% Deposit Scheme, the scheme requires you to live in the property. Moving out means notifying your lender, and the guarantee can end, so it is worth checking the scheme rules and your loan terms before making plans.
You will also need landlord insurance rather than standard home and contents cover, and the lender may ask for evidence of it. State-based charges such as land tax can apply once the property is no longer your principal place of residence.
Tax Changes Add Another Layer in 2026
The May 2026 Budget changed negative gearing and capital gains tax settings for established residential investment properties, with grandfathering for properties held before the Budget. How those rules apply to a former home that becomes a rental depends on the dates and your circumstances, which makes professional tax advice more important than usual before you commit to the move.
On the lending side, investment loan policy also varies more than it has for some time. Some lenders have changed how they count negative gearing benefits in serviceability, and pricing for investment loans differs widely between lenders.
Key Takeaways
- Most loan contracts require you to tell the lender when a property is no longer owner-occupied, and the rate may move to investor pricing.
- Interest deductibility generally depends on what the borrowed money was used for, so redrawing for personal spending can create problems.
- Money in an offset account is your own savings, while redraw is treated as new borrowing, and the difference matters for tax.
- Lenders usually count only around 75% to 80% of the rent from your former home when assessing the next loan.
- Using equity without cross-collateralising keeps each property and loan independent.
- Government guarantee schemes require owner-occupation, so moving out can end the guarantee.
