A significant transformation in the housing landscape is imminent as the federal government accelerates its Home Guarantee Scheme, which promises to provide an array of affordable homes for first-time buyers, effectively doubling their available choices practically overnight.

According to new statistics published on Wednesday by property analytics company Cotality, under the previous price constraints, about one-third of the roughly 5,000 evaluated house and unit markets across the country possessed a median value falling below the established thresholds.

With new, expanded limits set to be enacted on October 1, this percentage soars to 63 percent, covering 51 percent of the house markets and nearly 94 percent of the unit markets.

The initiative enables eligible first-time homeowners to bypass lenders mortgage insurance by affording them the chance to secure a home with just a five percent deposit. It will now be eliminating both income and geographic stipulations while simultaneously increasing property price ceilings in most areas.

Economist Kaytlin Ezzy pointed out that these changes offer first-time buyers a wider selection of properties, contributing to a more equitable market landscape for individuals who may not receive financial support from family.

“Historically, eligibility for the scheme required first-time buyers to predominantly focus on more economical housing alternatives, such as units and properties in suburban mortgage zones and regional locations,” she explained.

Under the old caps, first home buyers in Perth had access to just two suburbs with a median house value under the $600,000 limit: Medina ($590,786) and Mandurah ($589,965). 

That cap will be lifted to $850,000 next month. 

Choices in Brisbane and Adelaide were also largely limited to units, with only 36.9 per cent and 41.3 per cent of suburbs respectively falling under the old caps.

‘Since the caps were last revised in 2022, values across the mid-sized capitals have grown significantly, which has seen first-home buyers reliant on the scheme to purchase a house, essentially priced out,’ Ms Ezzy said.

‘The new price caps represent a substantial increase for most regions and are designed to be more in line with each region’s median house values.’

Across Sydney and the Illawarra, Newcastle and Lake Macquarie regions, the cap has increased by $600,000 to $1.5m. 

In Southeast Queensland and Adelaide, the caps have both increased by $300,000 to $1m and $900,000 respectively.

Adelaide saw the largest increase for houses, with 46.6 per cent or 130 suburbs now qualifying, up from just 2.9 per cent or just eight suburbs previously.

Brisbane saw the largest proportional increase for units, with 97.5 per cent of suburbs (153) now qualifying, up from just 36.9 per cent (58).

Rethink Residential director Mina O’Neill said the Australian property market is facing a ‘perfect storm’ with falling interest rates, a surge in listings, and the expansion of the Home Guarantee Scheme.

‘This spring we’re seeing a unique convergence of falling rates, more stock, and powerful policy incentives,’ she said.

‘It’s creating opportunities, but also fierce competition, and buyers who move early are in the strongest position to benefit before the market heats up further.’

However, she warned wealthy parents were leveraging the scheme by providing deposits in their children’s names. 

‘What’s intended to improve affordability risks widening inequality, as family wealth accelerates access for some while leaving others behind,’ she said.

‘With the cap raised to $1.5m in Sydney, no limit on places from October 1, and varying thresholds across states, the scheme is expected to fuel a fast-moving market.’

Ms Ezzy also conceded the scheme would put upward pressure on home prices.

‘While this is a demand-side policy that will undoubtedly put some upward pressure on values, it will help create a more equitable starting point and provide more options for those looking to get on the property ladder,’ she said.

The combined value of residential real estate rose to $11.7 trillion at the end of August, up 1.8 per cent over the quarter.

Shadow Housing Minister Senator Andrew Bragg slammed the scheme for not being means-tested, meaning anyone can use it.

‘Children of billionaires can now use the government’s mortgage insurance scheme. What a country!’ he wrote on X.

Bragg further told 2GB it was ‘pretty crazy’ the wealthiest Australians will be able to use the government welfare program to get access to their first house. 

Real Estate Institute of Australia president Leanne Pilkington said the accelerated rollout would make it easier for more Australians to enter the property market.

The scheme was originally scheduled to start in January 2026. 

However Ms Pilkington said while support for first-home buyers is vital, it must be complemented by supply-side measures to address the housing shortage. 

‘REIA also acknowledges the Government’s commitment to build up to 100,000 homes exclusively for first homebuyers,’ she said.

‘Policies that boost supply and provide targeted support for entry into the housing market are essential.’
