Why first home buyer grants make housing less affordable

When supply is constrained, giving buyers more money to spend does not make housing more affordable, it lets sellers charge more. Twenty years of first home buyer grants in Australia have been repeatedly capitalised into higher prices, transferring the benefit from the buyers the scheme is meant to

A first home buyer grant sounds like a straightforward gift: the government hands a buyer money, and that buyer is now closer to owning a home. In a housing market where supply cannot expand quickly, the evidence says the money rarely ends up with the buyer at all.

Bottom LineWhen supply is constrained, giving buyers more money to spend does not make housing more affordable, it lets sellers charge more. Twenty years of first home buyer grants in Australia have been repeatedly capitalised into higher prices, transferring the benefit from the buyers the scheme is meant to help to the existing owners selling to them.

The mechanism is mechanical, not political

The chain of cause and effect is simple. Government grants buyers more purchasing power. More buyers, each with more money, compete for the same limited number of homes. Sellers, rationally, raise their asking price to capture that additional purchasing power. The subsidy is "capitalised" into the asset price, and the buyer ends up no better off than before, having effectively paid the grant straight back through a higher purchase price while the seller pockets the difference. The variable that determines whether this happens is supply elasticity: if new supply can expand quickly to meet the extra demand, as in most competitive goods markets, subsidies don't move prices much. Where supply is constrained by zoning and slow approvals, as in Australian housing, subsidies flow almost entirely into price.

Two decades of the same result

Australia has run demand-side housing assistance since the First Home Owner Grant launched in 2000, and the price evidence has been consistent the whole way through. Research published through Deakin University found the FHOG directly increases house prices, and a review by the Australia Institute covering the full 20-year history concluded the grants have repeatedly failed to improve affordability. A 2024 analysis in Australian Economic Papers noted that Australian housing policy "stands out for its modern emphasis on demand-side assistance rather than supply-side measures," and NSW case studies have documented properties selling at exactly the grant's price cap, with buyers bidding each other up to that ceiling in real time. Grants also produce a bring-forward effect: buyer activity surges as people rush to use the grant before it changes, pushing prices higher in the short term, then demand collapses once the grant ends, leaving the market worse off on both sides of the policy.

What the alternative looks like elsewhere

Cities and countries that have kept housing affordable relative to income have generally done it through supply, not subsidy. Tokyo's permissive, continuously liberalised zoning has kept rents broadly stable despite strong demand. Houston's minimal zoning restrictions have produced housing costs well below comparable US cities. Australia has run the opposite experiment for decades: supply restricted through zoning, slow approvals, infrastructure levies and local opposition to new development, combined with a steady stream of demand-side subsidies, and the result is among the least affordable housing markets in the developed world relative to median income.

The same mechanism shows up outside housing

The pattern is not unique to housing. Subsidised HECS/HELP loans let students borrow more, which lets universities charge more, with the subsidy partly capitalised into rising tuition and administrative costs. Childcare subsidies show consistent international evidence of raising the market price of childcare, partly offsetting the benefit to families. Australia's private health insurance rebate, a 30 percent subsidy on premiums, has coincided with insurers raising premiums knowing government is absorbing a fixed share of the cost for many customers. In each case, a subsidy intended to make a constrained good cheaper for the buyer ends up, at least in part, making it more expensive to buy.

Why the policy persists anyway

Grants are popular because they are visible: a cheque, a scheme, a press conference. The price increase they cause is invisible: diffuse, delayed, and difficult for any individual buyer to trace back to the policy that caused it. Supply-side reform, zoning changes, faster approvals, removing developer levies, is unpopular for the opposite reason: it is politically difficult precisely because it threatens the asset values of existing homeowners who benefit from restricted supply. Australia currently runs several live versions of the same mechanism, including the federal First Home Guarantee, the Help to Buy shared equity scheme, and various state grants and stamp duty concessions, alongside a proposed scheme allowing superannuation to be accessed for a deposit. All of them increase purchasing power. None of them address supply.

Frequently asked questions

Do first home buyer grants help anyone?
In the very short term, buyers who purchase before a grant is capitalised into prices can benefit. But the twenty-year Australian pattern shows that benefit erodes quickly as sellers and the broader market adjust, and it does not persist as a lasting affordability gain.

Why don't grants just get spent on housing that already exists?
They do, that's exactly the problem. In a market where the number of homes for sale doesn't change, a grant does not create a new home, it changes what buyers can bid for an existing one.

Would grants work better if supply could respond faster?
Yes. The mechanism specifically depends on constrained supply. In a market where builders could quickly add housing stock in response to demand, a demand-side subsidy would do far less damage to affordability.

What would an effective affordability policy look like instead?
The evidence consistently points toward supply-side reform, zoning liberalisation, faster approvals, and removing barriers to new construction, as the lever that actually moves affordability, rather than putting more money in buyers' hands.
