She bought with a 5% deposit. Now she carries the downside

The invitation was clear. Skip the years of scrimping for a 20 per cent deposit, skip Lenders Mortgage Insurance, and get in with 5 per cent down, backed by the federal government's uncapped Home Guarantee scheme.

Australians took it. APRA data reported by realestate.com.au this week shows $15.6 billion in low-deposit loans written in the nine months since the scheme was uncapped.

Then the same environment delivered three cash rate hikes in 2026, with a fourth widely expected at the Reserve Bank's 28–29 September meeting. Values are sliding. The people holding the downside are the ones who accepted the invitation.

The buyer the policy was built for

What follows is a composite illustration. She is not a real person, and not connected to anyone named in this article or its sources.

She is 29. She bought her first home this year through the uncapped Home Guarantee scheme with a 5 per cent deposit, saved thousands in Lenders Mortgage Insurance, and got through the front door years earlier than she otherwise could have.

Since settlement she has absorbed three rate rises with almost no equity between her loan balance and her home's value. She did not overreach or gamble. She did precisely what the policy invited her to do — bought at maximum leverage, near what may prove to have been the top of the cycle.

If her suburb slips even modestly, she owes more than the place is worth.

The question nobody answered before she signed

What happens to a 5 per cent deposit when prices fall and rates rise at the same time? The brochure never addressed it. The numbers now answer it.

Loans written with a 5 per cent deposit made up 4.31 per cent of all new owner-occupier lending in the quarter — a meaningful cohort sitting on wafer-thin equity as the market turns.

Canstar's data insights director Sally Tindall put it bluntly: "The number of borrowers getting into the property market with barely any skin in the game has surged yet again, at the same time the housing market is shifting into reverse."

The stress signals are no longer theoretical:

• Mortgages 90 or more days in arrears now total $25.9 billion — 1.01 per cent of all mortgages, a second consecutive quarterly rise, and above the post-2019 average of 0.93 per cent.
• Loans 30 to 89 days past due rose for a second straight quarter, to 0.54 per cent of credit outstanding.
• 24 per cent of new mortgages in the June quarter were interest-only, up from 21 per cent a year earlier.
• Australians pulled $8.6 billion out of offset accounts in the June quarter — the biggest quarterly fall on record. The buffers are being spent.

"Mortgage arrears are starting to flash amber," Tindall said, "with the share of loans behind by 90 days or more now sitting above its post-2019 average." Her sharper line: "Borrowers have been remarkably resilient through the rate cycle, but resilience isn't an infinite resource."

Nor is the RBA riding to the rescue. Economists widely expect the September meeting to lift the cash rate to 4.6 per cent; RBC forecasts a peak of 4.85 per cent, with some seeing another hike in November. Deputy governor Andrew Hauser told the House Standing Committee on Economics: "We're probably rather closer now to a more sensible level of long-term global real interest rates than we were a year or two ago."

That is the setting, not a blip waiting to be reversed.

The asymmetry, stated plainly

This does not require a villain, only that the asymmetry be stated honestly. A scheme encouraged first home buyers to enter at maximum leverage. The wider policy environment then produced three rate rises and falling values. The people who designed the invitation carry none of that risk. The people who accepted it carry all of it.

Tindall's own read is not a doom call: "While many of these borrowers, particularly in Sydney and Melbourne, are likely to be in negative equity, if they can keep their head down and their mortgage payments up, they should be able to rise out of what can potentially become a tricky financial position."

That is the real point. Negative equity is crystallised only when you sell or refinance. Everything between now and then is decided by whether the asset underneath the loan holds.

What actually decides whether her street holds

Here is where the national numbers stop being useful. A 5 per cent deposit is not one risk. It is a completely different risk on two streets four kilometres apart, and almost nobody checks which one they bought on.

This is the work we do at street level rather than suburb level:

• R-Score compresses a street's fundamentals into one comparable number, so a buyer compares like with like instead of a suburb median against a headline.
• Street-level heatmaps show where value actually sits inside a suburb. Two addresses can share a postcode and a median and behave nothing alike through a downturn.
• Achieved versus advertised rent is the gap between the yield in the brochure and the yield in the bank account. On a thin-equity loan, that gap is the buffer.
• Street-level vacancy and days on market for that exact stock type show how fast the street clears when conditions tighten — exactly when a high-leverage owner needs it to.
• Approved-but-unbuilt competing supply within walking distance is the most commonly missed risk. Stock not yet built still competes with you the day it lands.
• Buyer depth on exit answers the only question that matters if life forces a sale: is anyone there to buy it?

Our composite cannot change the cash rate, the scheme or the cycle. What the next buyer still can change is which street the leverage sits on. A 5 per cent deposit is far more survivable on a street with depth, real achieved rent and no wall of approved supply behind it.

What this means for you

If you are buying with a thin deposit, the deposit is not the decision. The street is. Test the address, not the postcode: achieved rent against advertised rent, real vacancy, how long that exact stock type takes to sell, what is approved but not yet built nearby, and who is buying on exit.

If you already own with thin equity, the same data tells you whether to hold, reduce or restructure — before your bank does.

Headlines describe the market. Data describes your asset. The right asset on the right street, bought on evidence, is what survives a cycle like this one — and that is a case for property investment done properly, not against it.
