Settlement day is the worst day to be broke
The first year of home ownership is when the things no one warned you about start arriving: a failed hot water system, a council rates bill you forgot to budget for, an insurance premium that jumped. An — cash kept separate from your deposit and transaction costs — is the difference between absorbing these shocks and turning them into high-interest debt. Most first home buyers leave themselves no room.
- 40% of first home buyers had to pay unexpected fees, averaging $5,290 .
- 65% of first home buyers were already in, or expected to be in, .
- 24.9% of all mortgage holders — roughly 1.32 million Australians — are at risk of mortgage stress as of February 2026 .
These are not reckless buyers. They treated every saved dollar as deposit money and budgeted nothing for what came next.
Renters have a landlord, owners have a buffer
When you rent, a broken hot water system is your landlord's problem. When you own, it is yours. The first year of ownership is when you discover what the building inspection did not catch and what the previous owner deferred.
ASIC MoneySmart recommends having enough to cover at least three months of living expenses . For a new homeowner, that means mortgage repayments, council rates, insurance, utilities, food, and transport — all combined. If your monthly costs total $5,000, your minimum buffer is $15,000. Most financial advisers suggest stretching that to three to six months .
You are also adjusting to higher monthly costs than you had as a renter. Mortgage repayments, insurance, rates, and maintenance all land at once. Any single unexpected cost in that first year lands when you are least able to absorb it.
What the buffer is actually catching
Your buffer is for expenses you cannot predict or defer:
Unexpected cost | Typical range |
|---|---|
Hot water system replacement | $1,000 – $2,500 |
Roof leak repair | $500 – $5,000 |
Burst pipe (repair + water damage) | $500 – $4,000 |
Electrical switchboard upgrade | $1,300 – $2,000 |
(per lot) | $5,000 – $50,000 |
Interest rate rise (+0.25% on $600,000 loan) | +$95/month [10] |
Job loss or reduced income (3 months repayments at $3,500/month) | $10,500 |
A single item from this list can exceed $5,000. Two in the same year — a burst pipe and a rate rise, for example — could cost $10,000 or more. Without a buffer, that money comes from a credit card at 20%+ interest or a personal loan at 8% to 13%.
The cost of not having one is rarely just the repair
When a $3,000 repair lands and you have no savings, your options are:
- 1Credit card debt. At 20% interest, a $3,000 balance costs $600 a year in interest if you only make minimum payments. It takes years to pay off.
- 2Personal loan. Better than a credit card, but still 8% to 13% interest, and you are adding another monthly repayment on top of your mortgage.
- 3{Redraw facility} from your home loan. If your loan allows it, this is the cheapest option. But you are extending your mortgage and paying interest on that $3,000 for up to 30 years.
- 4Sell the property. In extreme cases, owners who cannot meet their repayments and have no buffer are forced to sell — often at a loss, and always with agent fees and marketing costs that eat into whatever equity they have built.
None of these options is as cheap as having the cash ready.
The 14% of buyers who settled with zero savings did not plan to be in that position. They treated every dollar as deposit money and left nothing for what came next .
