Should you rent out your first home when buying a second property?

The crossroads every upgrading homeowner faces

Many Australians reach a point where they're ready to move into a larger or better-located home — but they're not sure what to do with the property they're leaving behind. The instinct to hold it is understandable. You've built equity over years, you know the property intimately, and the prospect of rental income seems like a natural next step.

But the decision to convert your principal place of residence into an investment property is more complex than it first appears. There are tax consequences, financing considerations, and ongoing management obligations that aren't always visible at the outset. Understanding them before you commit can make a significant difference to the outcome.

Tax: what changes when your home becomes a rental

The moment you move out and begin renting your former home, the Australian Tax Office treats it as an investment property. That shift has two sides.

On the income side, all rental receipts become assessable income. You must declare them in your tax return each year. On the expense side, you gain the ability to claim deductions — including interest on the mortgage, property management fees, council rates, insurance, and depreciation on the building and its fixtures. Whether these deductions exceed your rental income determines whether the property is positively or negatively geared.

The more significant tax issue, however, is Capital Gains Tax. While your home is your principal place of residence, it is exempt from CGT. Once you rent it out, that exemption begins to erode. The six-year rule offers some protection: if you are absent from the property for up to six continuous years, you can still treat it as your main residence for CGT purposes — provided you don't nominate another property as your main residence during that period. If you sell within six years of moving out, you may avoid CGT entirely. Sell after six years and CGT applies from the date you vacated.

These rules interact with your overall tax position in ways that aren't always straightforward. Speak to your accountant before making any decision. The right timing — on both the move and any eventual sale — can make a material difference.

Rental income versus the cost of holding

Before you commit to renting the property, run the numbers honestly. The key question is whether the rental income will cover — or at least approach — the ongoing costs: mortgage repayments, property management fees, council rates, insurance, maintenance, and any periods of vacancy.

Many properties in Brisbane and the surrounding region are negatively geared, meaning the rental income doesn't fully cover these costs. That's not necessarily a deal-breaker — the tax deduction on the shortfall, combined with anticipated capital growth, might still make it worthwhile. But it does mean you need to be able to fund that gap from your own pocket each month, in addition to servicing the mortgage on your new home.

The picture is further complicated if your first home needs preparation work to achieve the rent it could potentially command. A property that shows its age will either sit vacant longer or attract a lower rental rate. Factor that into your projection.

The management question

Once you've decided to rent, you need to decide how. The three main options each come with different trade-offs.

Self-managing removes the agency fee — typically 8–12% of gross rent — but it puts you directly responsible for finding and vetting tenants, managing lease agreements, handling maintenance requests, complying with Queensland tenancy legislation, and navigating disputes. If you're also settling into a new home and managing a new mortgage, that's a meaningful additional load.

A traditional property manager offloads the day-to-day work, but you're still the landlord of record. You approve maintenance spend, you deal with vacancies, and you bear the legal and financial risk of the tenancy. Management fees vary, and the quality of service varies considerably more.

A structured income model operates differently. Rather than acting as your agent, a partner takes on the property directly — managing occupancy, maintenance, and compliance — and pays you a predictable income in return. The trade-off is that you cede some control over how the property is used. The potential upside is above-market gross returns without the burden of being a landlord.
