For three years, the advice given to priced-out Australian buyers was essentially "hold on". Wait for the market to turn, wait for the froth to come off, wait for the day the median stops sprinting away from your deposit. Well - it turned. NAB now expects Sydney values to fall 10% and Melbourne 9% across 2026, and it downgraded capital city prices from a 2% fall to a 5% fall in the space of a single month. The correction that everyone waited for is here.
And a great many of the people who waited for it are worse off than they were in January.
That is not a mood or a vibe. It's arithmetic, and it comes from the RBA's own rate decisions. While the price tag was falling, the ruler used to measure what you can afford was shrinking faster.
The number that moved more than the price did
Canstar ran the maths on what this year's three increases - February, March and May, which took the cash rate from 3.60% to 4.35% - have done to what banks will actually lend.
Each hike took a bite of roughly the same size out of a single average earner's capacity: about $12,200 after February, $11,800 after March, $11,400 after May. Cumulatively that is $35,400 gone for a single buyer, and $70,700 for a couple both on average wages. Not a change in what they want to spend. A change in what a lender will approve.
Set that against what prices are forecast to do, and the picture gets uncomfortable. Using NAB's revised numbers, here is where the six capitals are tipped to land by the end of 2026, measured against where they began the year:
- Sydney: down about $162,400
- Melbourne: down about $89,600
- Brisbane: up about $23,100
- Perth: up about $50,300
- Adelaide: up about $9,700
- Hobart: up about $38,400
Read that list again, because the headlines have not. Australia is in a "property downturn" in which four of the six capitals are still expected to end the year above where they started. A Brisbane or Perth buyer who spent 2026 waiting for the correction watched the price rise and their borrowing budget fall by $70,700 at the same time. They did not get a discount. They got a demotion.
Sydney is the honest exception. A $162,400 fall is considerably larger than $70,700, so a Sydney buyer really has gained ground on paper. But the Sydney buyer also needs the largest loan in the country, which means a given percentage cut to serviceability costs them more dollars than anyone else - and it means the gain only converts into a purchase if the bank still says yes.
Why waiting from here is a bet, not a strategy
The more useful question is not what happened, but what the next six months look like for someone still on the sidelines. On NAB's forecasts, the falls still to come between August and December are considerably smaller than the year-to-date headlines suggest: roughly $67,300 in Sydney, $30,700 in Melbourne, $30,800 in Adelaide, $28,400 in Brisbane, $17,200 in Perth, and a small rise in Hobart.
Now put a fourth rate hike next to those numbers. Canstar estimates that a fourth increase would deepen the capacity hit to $46,300 for a single and $92,500 for a couple - an incremental loss of roughly $10,900 and $21,800 respectively.
In other words: one more hike would cost a couple more borrowing power than Perth's entire remaining forecast price fall, and roughly three-quarters of Brisbane's, Melbourne's or Adelaide's. The buyer waiting for the rest of the correction is, without quite realising it, betting that the RBA is finished. The Board is not saying that. It held at 4.35% this afternoon in a unanimous decision, but the statement explicitly kept the door open, committing to do what it considers necessary "including increasing the cash rate target further if upside risks materialise". Ahead of the decision, a Finder survey found 44% of economists expect at least one more increase before the year is out.
Sally Tindall, Canstar's data insights director, put the trap plainly: "For would-be buyers, this is shaping up to be a classic case of one step forward, two steps back. While falling property prices may look like a win for people trying to get into the market, higher interest rates are keeping borrowing budgets in a bind."
The mechanism: why budgets shrink faster than price tags
The reason capacity moves so violently is APRA's serviceability buffer. Lenders don't assess you at the rate you'll pay - they assess you at that rate plus three percentage points. With the average variable rate around 6.92%, a typical applicant is being tested at close to 10%.
That buffer acts as a multiplier on every RBA move. A 0.25% increase to the cash rate doesn't just raise your repayment - it lifts the entire assessment rate the bank models you against, across a 30-year term. The result is that a rate rise measured in fractions of a percent removes tens of thousands of dollars of approved lending.
It is also worth knowing what Canstar's figures assume, because most real buyers do worse. The modelling uses a 30-year owner-occupier loan at the average new-customer rate, annual living expenses of $24,000 for a single and $48,000 for a couple, and - critically - no other debts, no dependants, and no existing obligations. Add a HECS balance, a car loan, a credit card limit you never use, or children in care, and the fall in your own capacity will be steeper than the published averages.
What this means if you're actually in the market
The strategic conclusion is not "buy now" and it is certainly not "prices will crash, keep waiting". It's that the two halves of affordability have decoupled, and only one of them is inside your control.
- Stop tracking the median and start tracking your approval. The relevant number is not what the market did last month - it's what a lender will advance you this month. Get it re-measured rather than assumed; if your last assessment predates May, it is out of date.
- Attack the inputs you control. You cannot influence the cash rate. You can close unused credit card facilities (banks assess the limit, not the balance), clear or consolidate small personal debts, and tidy up three months of spending before you apply. These move your capacity in the opposite direction to the RBA.
- Understand that lenders differ - sometimes materially. Assessment rates, living-expense benchmarks and treatment of bonus or overtime income are not uniform across the market. Two lenders can look at identical payslips and arrive at meaningfully different numbers.
- If you're already approved, know your expiry date. Pre-approvals typically run three to six months, and a renewal is a fresh assessment at today's settings. An approval issued in January is not the approval you have now.
- If you're refinancing, test it early. Roy Morgan has 30.3% of mortgage holders at risk of mortgage stress, with 1.06 million now "extremely at risk" - up from 16.7% of holders in December. Around a dozen lenders currently advertise variable rates under 6% against a 6.92% average, but the same serviceability squeeze that shrank buyers' budgets can also block a refinance. Find out whether the door is open before you need it.
The buyers who navigate the next six months well won't be the ones who correctly predict the bottom. They'll be the ones who understood that a falling market and a shrinking borrowing capacity can, and currently do, cancel each other out - and who spent their energy on the half of that equation they can actually change.

Frequently Asked Questions
How much has borrowing capacity fallen in Australia in 2026?
Canstar estimates the three RBA rate hikes in February, March and May 2026 have cut about $35,400 from the maximum borrowing capacity of a single average income earner, and about $70,700 from a couple both earning average wages. A fourth hike would extend those falls to roughly $46,300 and $92,500 respectively.
If house prices are falling, why is it still hard to buy in Australia?
Because borrowing capacity has fallen alongside prices, and in most capitals it has fallen further. Four of the six capitals NAB tracks are still forecast to end 2026 above where they started the year, while the average couple's borrowing budget shrank by around $70,700. A lower price only helps if a lender will still approve the loan you need.
What is the serviceability buffer and how does it affect my home loan?
APRA requires lenders to assess your ability to repay at your actual interest rate plus three percentage points. With average variable rates near 6.92%, most applicants are assessed at close to 10%. This buffer multiplies the effect of every RBA move, which is why a 0.25% rate rise can remove more than $10,000 from an individual's approved borrowing.
Should I wait for house prices to fall further before buying in Australia?
That depends on whether the RBA is finished, which is not settled - 44% of economists surveyed by Finder expect at least one more increase before the end of 2026. On NAB's forecasts, one further hike would cost a couple more borrowing power than Perth's entire remaining projected price fall, and around three-quarters of Brisbane's, Melbourne's or Adelaide's. Waiting is a position on interest rates, not just on prices.
How can I increase my borrowing capacity in 2026?
Focus on the inputs you control. Closing unused credit cards helps because lenders assess the full limit rather than the balance, and clearing or consolidating small personal debts frees up assessed income. Tidying up three months of discretionary spending before applying also matters, as does lender choice - assessment rates and living-expense benchmarks are not uniform across the market.
