You’ve saved the deposit. You’ve got pre-approval. You’ve done the open home circuit and finally found the one. It feels like the hard part is over – but in many ways, the financial planning is just beginning.
The purchase price is only the starting line. Beyond it sits a stack of upfront costs that hit before you even get the keys, followed by ongoing annual expenses that follow you for the life of the loan. Most buyers plan carefully for the mortgage repayment and leave everything else to chance. That gap between what buyers budget for and what homeownership actually costs is where financial stress quietly builds.
This guide breaks down every major cost category Australians routinely underestimate – from settlement day through years of ownership – so you can go in with a clear picture rather than an uncomfortable surprise.
The Upfront Costs That Hit Before You Get the Keys
The deposit gets all the attention, but the costs sitting alongside it can easily add another 5–7% on top of the purchase price. On an $800,000 home, that’s between $40,000 and $56,000 in additional funds you need to have ready before settlement.
Stamp Duty – The One Nobody Escapes
Stamp duty is a state government tax on property purchases, and it’s one of the largest upfront costs most buyers face. The amount varies significantly depending on where you buy and whether you qualify for any concessions.
In NSW, stamp duty on a $750,000 property sits around $28,000–$30,000 for a standard purchaser. In Victoria, a property between $960,001 and $2,000,000 attracts a flat 5.5% rate on the full purchase price. Queensland, WA, and SA each have their own thresholds and rates – and the differences between states can run to tens of thousands of dollars on the same property value.
First home buyers may qualify for exemptions or concessions depending on their state and the property price. These eligibility rules change regularly, so it pays to check with your state revenue office or a conveyancer early in the process.
Conveyancing, Inspections, and Lender Fees
Beyond stamp duty, several other upfront costs stack up quickly:
| Cost | Typical Range |
| Conveyancing / legal fees | $1,500 – $3,500 |
| Building and pest inspection | $400 – $800 |
| Lender application and settlement fees | $500 – $1,500 |
| Mortgage registration fee | $100 – $200 |
| Lenders mortgage insurance (LMI) if deposit under 20% | $21,850 – $35,500+ |
Building and pest inspections are optional in a legal sense, but skipping them is rarely worth the risk. Structural problems, water damage, and termite activity discovered after purchase can cost far more than the inspection fee to fix. On an older property especially, treat the inspection as non-negotiable.
LMI is worth understanding before you commit to a deposit size. On an $800,000 property with a 10% deposit, LMI can cost $21,850–$35,500. With a 5% deposit, the figure can climb beyond $35,000. Some first home buyers can avoid LMI entirely through government guarantee schemes – worth investigating before you assume it applies to you.
What You’ll Pay Every Year, Whether the House Needs Work or Not
Once you’re in, a predictable set of annual costs arrives regardless of whether anything goes wrong with the property. These are worth factoring into your monthly budget from day one.
Council Rates and Water Rates
Local councils charge annual rates to fund waste collection, road maintenance, and community infrastructure. In metro areas across Australia, council rates for a house typically run $1,500–$3,000 per year. Water rates add to that, covering your connection to the water and sewerage network separate from what you use.
These figures vary by council and property value, but treating $2,500–$4,000 combined as a baseline planning figure for most metro properties is a reasonable starting point.
Home and Contents Insurance
Home insurance is not optional when you have a mortgage – your lender will require it. And the cost has been climbing. The national average for home and contents insurance now sits around $3,499 per year, following a 14% increase in 2025. Queensland and Northern Territory homeowners pay considerably more due to cyclone and flood risk, with QLD averages reaching $4,398 annually.
That’s a meaningful line item in any monthly budget. If you’re working out your monthly repayment budget and trying to understand how insurance, rates, and mortgage repayments all interact, a loan repayment calculator can help you see the full picture rather than just the headline mortgage figure.
Premiums vary by location, sum insured, excess, and policy. Comparing providers annually rather than auto-renewing is one of the more straightforward ways to manage this cost over time.
Maintenance and Repairs – The Cost Buyers Underestimate Most
This is where the gap between buyer expectations and reality tends to be widest. Maintenance isn’t a one-off cost – it’s a permanent feature of homeownership, and it scales with the age and size of the property.
The 1% Rule (and Why It’s Often Not Enough)
The widely used rule of thumb is to budget 1–2% of your property’s value each year for maintenance and repairs. On an $800,000 home, that means setting aside $8,000–$16,000 annually.
Research into what Australian homeowners actually spend puts the average at $8,000–$15,000 per year on maintenance, repairs, and replacements – beyond the mortgage, rates, and insurance. Older homes often cost significantly more to maintain. Properties built before 1980 frequently have ageing plumbing, roofing approaching end-of-life, and electrical systems that may need upgrading, pushing the realistic budget to 2–4% of property value annually.
The 1% rule is a floor, not a ceiling. New builds generally stay well under it. A 40-year-old brick veneer in the inner suburbs is a different story.
The Trades You’ll Call More Than Once
Plumbing consistently ranks among the most common and most stressful maintenance costs for Australian homeowners. Blocked drains, leaking pipes, failing hot water systems, and worn-out fixtures are recurring realities of owning an older property – and they rarely announce themselves at a convenient time.
Emergency callouts attract a significant premium over standard service rates – typically 50–100% above what you’d pay for a scheduled job during business hours. Building a relationship with a reliable trade before you need them urgently is one of the more practical steps any homeowner can take. A licensed Sydney plumber available around the clock can be the difference between a minor inconvenience and a flooded bathroom at 11pm.
Here’s a rough guide to common repair costs most homeowners encounter:
| Repair / Service | Typical Cost Range |
| Blocked drain clearing | $150 – $400 |
| Hot water system replacement | $1,200 – $3,500 |
| Roof inspection and minor repairs | $300 – $800 |
| Gutter cleaning | $150 – $350 |
| Electrical switchboard upgrade | $1,500 – $4,000 |
| Bathroom waterproofing and resealing | $400 – $1,200 |
| CCTV drain inspection | $200 – $400 |
None of these figures are alarming on their own. The issue is that they rarely come one at a time.
The Surprise Costs Most Buyers Never See Coming
Beyond the predictable annual costs, a few categories tend to catch buyers completely off guard.
Moving Costs and Utility Setup
Removalists for an average household move in a metro area typically cost $800–$2,500 depending on volume, distance, and timing. Add utility connection fees – electricity, gas, and internet setup can run $300–$700 for new connections – and you’re looking at a real cost that buyers often leave out of the budget entirely.
These aren’t large numbers in isolation, but when they land in the same week as settlement costs and a mountain of moving boxes, they add up fast.
Deferred Maintenance From Previous Owners
Pre-purchase building inspections are thorough, but they don’t catch everything. Water damage behind walls, inadequate roof drainage, electrical systems that are legal but outdated, and cosmetic work that’s been covering up moisture – all of these can surface in the first year of ownership.
Buyers of older properties should carry a buffer specifically for catch-up maintenance. Issues like these tend to be interconnected: a minor roof leak can mean ceiling damage, mould growth, and electrical concerns that all need attention at once. Setting aside a specific fund for the first twelve months of ownership is a practical way to absorb whatever the property reveals.
How to Build a Budget That Actually Covers Everything
The Emergency Fund Rule
Most financial advisers recommend keeping $5,000–$10,000 in a dedicated home maintenance reserve on top of your general savings. This isn’t the same as your emergency fund for living expenses – it’s specifically for the property. A hot water system failure, a plumbing emergency, or a burst pipe doesn’t wait for a convenient moment. Having access to funds without reaching for a credit card keeps these events manageable rather than destabilising.
Running the Real Numbers Before You Sign
How much should I save beyond my deposit?
A practical target is the deposit plus 7–10% of the purchase price for all upfront costs, plus a minimum of $10,000 as a first-year ownership buffer. From there, factor in annual costs – rates, insurance, and maintenance – as a monthly line item rather than treating them as variable unknowns.
Working backwards from the total cost of ownership rather than just the repayment figure gives you a far more honest picture of what a property will actually cost you each year. It also makes the difference between properties more visible – a cheaper house with significant deferred maintenance may cost more to own than a newer property at a higher purchase price.
Buying With Your Eyes Open
Homeownership is one of the most significant financial decisions most Australians will ever make, and the long-term case for it remains strong. But the buyers who navigate it best are the ones who go in with an honest picture of total cost – not just the repayment figure on the pre-approval letter.
Stamp duty, conveyancing, inspections, annual rates, insurance, and ongoing maintenance are not extras. They are the cost of owning a home. Building them into your planning from the start means fewer surprises, less financial stress, and a lot more confidence in the decision you’re making.
