$10 a week, or $2? The rent forecast nobody is checking at street level

Two numbers were published about the same policy this month, and they do not agree.

The Federal Government says its housing package will lift rents by less than $2 a week for a household on the current median rent, deliver around 75,000 additional owner-occupiers over the next decade, and leave house-price growth about 2 per cent lower than it otherwise would have been.

Four peak property and construction bodies commissioned their own economists — Qaive and Tulipwood Economics — and came back with something else entirely: rents approximately 1.69 per cent higher by 2029–30 than under a no-policy-change baseline, which the industry groups characterise as roughly $10 a week. Five times the government's figure.

One of those numbers is wrong. The renter does not get to find out which one until it has already happened to her.

The person in the middle

She is 29. She rents a two-bedroom unit with a housemate on the outer edge of a capital city, and she has been putting money aside for a deposit for three years. She did not lobby for negative gearing changes and she did not lobby against them. She has no position on limited recourse borrowing arrangements inside self-managed super funds. She simply pays rent, and then saves whatever is left.

If the government is right, this package costs her about $104 a year. If the industry modelling is right, it costs her about $520 a year — most of a month's rent, taken out of the deposit she is trying to build, by a reform sold partly on the promise of helping people exactly like her buy a home.

That is the injustice worth naming. Not that the policy is good or bad. That the person with the least ability to absorb the downside is the one carrying the forecast risk, while every party to the argument has a commercial or political interest in their own number.

What the modelling actually says

Be precise about the provenance here, because it matters. This is industry-commissioned modelling, released by bodies with a direct stake in the outcome. It is not a neutral umpire. Read it as an argument, not a verdict.

With that caveat, the numbers are specific enough to be testable. The analysis examines the combined effect of changes to negative gearing and capital gains tax concession arrangements, the $2 billion Housing Support Program, and a measure preventing self-managed super funds from using limited recourse borrowing arrangements to buy ordinary residential investment property — the last of which was added during negotiations between Labor and the Greens.

Combined, the modelling estimates:

- Approximately 10,700 fewer new dwelling starts over the four years to 2029–30 - Cumulative GDP lower by about $1.05 billion - Construction employment lower by approximately 4,740 FTE-years - Rents approximately 1.69 per cent higher by 2029–30

The effect compounds rather than arriving all at once. New dwelling starts are estimated to be 1,424 below baseline in 2026–27, then 2,351 in 2027–28, 3,067 in 2028–29, and 3,851 in 2029–30. The SMSF measure alone accounts for around 1,950 of the 10,700, plus about $1.15 a week on average rents.

The economists say they built the analysis from ATO SMSF statistics, APRA superannuation figures, ABS Lending Indicators and ABS Building Activity before applying the estimated shocks. And with a national target of 1.2 million homes already under pressure, removing 10,700 dwellings from the pipeline is not a rounding error.

The question

So which number should she plan around — $2 or $10?

Neither. Both are national averages, and nobody has ever paid a national average in rent.

That is the part of this argument that never gets made. A 1.69 per cent national rent effect is an aggregate of tens of thousands of local markets, some of which will feel nothing at all and some of which will absorb three or four times the headline. The variation between two streets in the same postcode is routinely larger than the entire difference between the government's forecast and the industry's.

The answer sits below the suburb

Here is what actually determines whether a supply pullback lands on a given street.

Competing approved supply. A street with 340 approved-but-unbuilt dwellings inside a one-kilometre radius has a rent ceiling regardless of what happens to national starts. A street with fourteen does not. When the build pipeline thins, those two streets move in opposite directions — and the second one is where a supply shock converts into a rent increase.

Achieved rent versus advertised rent. Advertised rent tells you what someone hoped for. Achieved rent tells you what a tenant actually signed. On tightening streets the gap closes and eventually inverts. That inversion shows up months before any national index registers it, and it is the earliest honest signal that supply has turned.

Street-level vacancy and days on market. A suburb-level vacancy rate of 1.4 per cent can be one street at 0.3 and another at 3.1. Days on market for the street's specific stock type — not the suburb's blended figure — tells you whether a two-bedroom unit there is scarce or merely listed.

Buyer depth on exit. Policy changes that reduce investor participation do not reduce it evenly. They thin the buyer pool hardest in the stock types investors dominate. If your exit depends on selling to an investor, that is a risk you can measure now rather than discover in 2029.

This is the work Ripehouse Advisory does at street and suburb level — R-Scores, street heatmaps, achieved-rent series, competing-supply counts — because the difference between $2 and $10 is a headline, and the difference between two streets is the actual outcome.

What it means for you

If you rent, the honest answer is that you cannot control the policy, but you can read the street. Competing supply and vacancy on the specific streets you can afford will tell you more about your next lease than any Canberra forecast will.

If you invest, the reframe is the same one it always is. A package that removes 10,700 dwellings from the national pipeline is not a reason to retreat from property; it is a reason to be far more specific about which property. Thinner supply rewards assets on streets with genuine scarcity and punishes assets sitting in front of an approved pipeline. The headline treats those as the same trade. They are not.

The right asset, on the right street, chosen on data rather than on whose modelling you believe — that is what beats the headline. It always has.

Want to know how a supply pullback lands on your street rather than the nation? That is exactly what a street-level assessment is for.
