Rentvesting in 2026: who it actually works for (and who it doesn't)

Westpac's 2025 Home Ownership Report found 54% of first home buyers are now considering rentvesting, climbing to around 61% in New South Wales. The idea is seductive: keep renting where you actually want to live, buy an investment property somewhere more affordable, and let the tax system do some of the work. It can be a genuinely smart move, but it is not the free lunch it is often sold as. Whether it beats buying your own home depends heavily on which grants and schemes you would otherwise be walking away from.

What rentvesting actually involves

Rentvesting means buying a property you do not live in. In tax terms that is an investment property, not a principal place of residence, and the difference is not cosmetic. It changes what you can access and what you pay.

• You lose access to owner-occupier support. The First Home Owner Grant, the federal First Home Guarantee (5% deposit scheme) and Help to Buy all require you to live in the property, usually within 12 months of settlement and for a minimum period after that.
• You gain tax deductibility. Interest on the investment loan, property management fees, insurance, council rates, repairs and depreciation are generally deductible against your rental income and, if the property runs at a loss, against your other income.
• Your interest rate is higher. Investor loans typically sit around 0.30 percentage points above owner-occupier rates, and lenders assess your borrowing capacity on top of any rent you are still paying yourself.

Persona A: rentvesting can work well

Consider a 28-year-old on $95,000 renting a small apartment in inner Sydney for around $700 a week. Buying anything within a reasonable commute is well out of reach, and none of the current schemes bring a Sydney purchase into their budget.

They buy a $550,000 investment townhouse in Ipswich at roughly a 5.5% gross yield, so rental income lands near $580 a week. At an investor rate around 6.5%, interest alone runs close to $680 a week, producing a negative gearing loss of about $100 a week. At a 32.5% marginal tax rate that loss returns roughly $33.50 a week in reduced tax, so their net out-of-pocket on the investment is about $66.50 a week.

Add the $700 rent they are still paying and their total weekly housing cost sits near $766, versus more than that just to service a mortgage on any Sydney entry point, before rates, insurance and strata. On top of that, they own an appreciating asset in a market with reasonable growth prospects. For this buyer, rentvesting is a rational choice, not a workaround.

Persona B: rentvesting quietly costs a fortune

Now consider a couple in their mid-twenties earning $140,000 combined in Brisbane. They may be eligible for Help to Buy and the First Home Guarantee on a $700,000 Queensland house, and if they buy a new build they could also access the $30,000Queensland First Home Owner Grant and a full stamp duty concession worth around $17,400.

If they rentvest instead, every dollar of that support evaporates. The federal Help to Buy equity contribution alone could be worth up to 40% of the purchase price on an eligible home. Once you add the grant, the stamp duty saving and the interest-rate saving on an owner-occupier loan, the combined value can comfortably exceed $300,000 over the first several years of ownership.

A modest tax deduction on a negatively geared investment does not catch that up quickly. For buyers in a grant-rich position, the owner-occupier schemes are often worth more than the tax benefits of rentvesting, and it is easy to walk past that value without realising.

Persona C: the honest maybe

A Melbourne buyer wants to live in St Kilda but has a $550,000 budget. St Kilda entry prices start well above $700,000, so buying to live is not realistic today. They could buy a $550,000apartment in Ballarat as an investment, keep renting in St Kilda, and revisit the plan in five to ten years.

Whether that is better than waiting, saving harder, or moving further out to buy something they can live in depends on assumptions about capital growth, rental yield, interest rates, and their own income trajectory. This is the case where a calculator earns its keep. Use the Rentvesting Calculator to model your five and ten year wealth position, and cross-check against the Rent vs Buy Calculator for the owner-occupier alternative.

Tax and future-buyer gotchas

Rentvesting has a few consequences that only show up years later:

• Capital gains tax on sale. Investment properties do not get the main residence CGT exemption. If you eventually sell to buy your own home, the capital gain is taxable, with a 50% discount if the property was held for at least 12 months, then added to your income at your marginal rate.
• No equity in your own home. You are still renting, so you are not building equity in the roof over your head. When you later apply for an owner-occupier mortgage, lenders will assess your existing investment debt and rental commitments alongside the new loan.
• Land tax and vacancy risk. Investment properties can attract land tax above state thresholds, and any vacancy period is a cost you carry personally.

The honest verdict

Rentvesting is most powerful when you are effectively locked out of owner-occupier support: your income is too high for the caps, the homes you would live in exceed the price caps, or your preferred city has no realistic entry point. In those cases the tax benefits and access to a growth market can genuinely compound wealth faster than waiting.

For eligible first home buyers with clean access to the First Home Owner Grant, the First Home Guarantee, or Help to Buy, the owner-occupier path usually wins in the first five to seven years by a wide margin. The right answer is almost never universal, and a mortgage broker or licensed adviser can help you weigh your specific situation.

What this means for you

• Work out the full value of the owner-occupier support you may be eligible for before you rule out buying to live.
• If you are already priced out of your preferred city, model rentvesting properly rather than assuming it is smart or reckless by default.
• Factor in the investor rate premium, future capital gains tax and the impact on your next borrowing application, not just this year's tax deduction.
