Housing Australia has confirmed that 1,486 homes bought under the government's 5% first-home-buyer deposit scheme were turned into investment properties between the scheme's 2020 launch and May 2026. The data came out in response to a Senate estimates question on notice in June (Guardian Australia).

That number is a small slice of the 208,000 total guarantees issued over the same period. But it lands at a moment when the scheme's design choices are under fresh scrutiny, after the Albanese government removed income caps from the First Home Guarantee in October 2025 and opened it to every first-home buyer regardless of earnings.

Here's how the scheme works. First-time buyers can borrow 95% of a property's value, with the government guaranteeing the loan and waiving lenders' mortgage insurance — the insurance banks normally force on borrowers with a deposit under 20%. The guarantee covers up to 15% of the property's value, according to Housing Australia's own scheme documentation. Since the October 2025 expansion, the scheme has backed an average of more than 5,600 home purchases per month, up from roughly 3,400 per month in the prior year. Guardian Australia reported in July 2026 that one in three new participants earned above the scheme's previous income caps of $125,000 for singles and $200,000 for couples. The scheme can be used to buy a Sydney home valued up to $1.5 million with a 5% deposit (ABC News).

The rules around investment conversion are fairly straightforward. When a scheme participant stops living in the property, the government guarantee no longer applies. The buyer must negotiate with their bank but is not forced to sell or refinance. Housing Australia says it monitors rental listings, property datasets, participants' transaction activity and changes of address to ensure scheme properties remain owner-occupied.

What that monitoring actually catches, and when, is the live question. The 1,486 conversions were detected and recorded, but the data does not distinguish between buyers who moved out promptly and those who held the property as a primary residence for years before turning it over. For a scheme whose political selling point is helping people get a foothold, the gap between "no longer your home" and "now an investment property" is doing a fair bit of work.

The government promotes the expanded scheme as cutting years off the time needed to save a deposit. The Australian government's own social media channels have framed it in precisely those terms since April 2026 (Australian Government). Housing Australia estimates the average equity gain per guarantee at around $82,000 since 2020, a figure the agency has highlighted in collaboration with major lenders since 2023.

The scheme's footprint has grown steadily. The First Home Guarantee's annual places rose from 10,000 to 35,000 from 1 July 2022, with the introduction of the Regional First Home Buyer Guarantee adding another 10,000 and bringing total annual Home Guarantee Scheme places to 50,000. The Parliamentary Budget Office costed the Albanese government's 2025 election commitment titled "Delivering 100000 homes and 5% deposits for all first home buyers," whose Component 2 would expand the First Home Guarantee so every Australian could buy their first home with a 5% deposit (Parliamentary Budget Office). That commitment has since been implemented.

The parliamentary and industry response to the scheme's mechanics has been mixed. The Australian Finance Industry Association argued in a May 2026 submission to Parliament that mortgage serviceability assessments — the checks banks use to determine whether a borrower can repay the loan — should recognise student debt as an investment in lifetime earnings, a proposal that would expand borrowing capacity for exactly the cohort the scheme targets. Separately, parliamentary documents note that under the First Home Guarantee, lenders can use enhanced self-employed and investment income in mortgage serviceability assessments.

The broader context here is that the scheme has evolved from a targeted affordability measure into a near-universal first-home-buyer subsidy. The income caps are gone. The property price ceilings are generous. The participant base now skews materially higher up the income distribution than the original designers intended. Whether 1,486 conversions out of 208,000 guarantees is a rounding error or a design flaw depends on your vantage point. The government will call it marginal. Critics will call it evidence that a scheme meant to get people into homes is also helping some of them build portfolios.

What the data does not tell us is how many of those 1,486 investors used the equity gains from their guaranteed first home to leverage into additional property. Housing Australia's $82,000 average equity figure suggests the scheme has been a wealth accelerator for participants, not just a deposit shortcut. That is not a failure of the policy exactly; it is what happens when you underwrite leverage into a rising market. But it is a long way from the framing of "helping first-home buyers" that the government prefers.

Teachers Mutual Bank joined the scheme's participating lender panel in July 2026, the latest in a steady expansion of access points. The scheme's institutional architecture is still growing. The question for parliament, and for anyone watching the housing portfolio, is whether the guardrails around owner-occupation are commensurate with a program that is now backing over 67,000 loans a year.
