Home Guarantee Scheme Expansion Fuels Price Surge in Australia’s Entry-Level Property Market

The expansion of Australia’s Home Guarantee Scheme (HGS) has emerged as a primary driver of price inflation in the lower-end property market, according to new data that highlights a growing divergence in the national housing landscape. Between October 2025 and March 2026, properties valued below the scheme’s price caps recorded a 6.7% price increase—nearly double the 3.6% growth seen in the more expensive segments of the market.

Analysis from property analytics firm Cotality indicates that this trend has persisted despite a broader cooling of the Australian property sector. While national dwelling values rose by a modest 0.3% in April 2026, and major markets like Sydney and Melbourne recorded monthly declines of 0.6%, the entry-level segment remains buoyed by government-backed demand.

The Mechanics of the Expansion

The current market conditions follow significant changes to the HGS that came into effect on October 1, 2025. Housing Australia, the agency overseeing the program, removed previous income caps and place limits while simultaneously increasing property price caps across all states and territories. The move was designed to assist first-home buyers in navigating a high-interest-rate environment by allowing them to purchase with deposits as low as 5%—or 2% for single parents—without the added cost of Lenders Mortgage Insurance (LMI).

In the first six months of the expanded program, approximately 60,000 buyers utilised the scheme. However, the concentration of these buyers within specific price brackets has created a 'two-speed' market. In 81 of the 88 (92%) SA4 sub-markets analysed by Cotality, growth for sub-cap homes outperformed the broader market. The divergence was most acute in Sydney, where sub-cap homes gained 4.1% in value while properties above the cap fell by 1.1%.

Disputed Projections and Market Reality

The rapid price escalation in the lower-end market has reignited criticism of the Treasury’s initial impact assessments. Treasury modelling had previously suggested the scheme would result in a modest 0.5% price increase over a six-year period. The reality of a 6.7% jump in just six months has led industry experts to question the accuracy of those forecasts.

Prior to the expansion, the Reserve Bank of Australia (RBA) and several independent economists warned that stimulatory demand-side policies, in the absence of significant supply increases, would inevitably put upward pressure on prices. "When you provide more borrowing capacity to a specific segment of the market without increasing the number of available homes, the result is almost always price inflation within that segment," noted one senior economist.

This inflation may be creating a 'Pyrrhic victory' for first-home buyers. While the HGS allows them to enter the market sooner by bypassing LMI, the resulting price hikes mean they are often taking on larger mortgages than they would have six months ago, potentially offsetting the initial savings.
