Key Takeaways
- Set a property-specific maintenance allowance based on the home’s age, condition, inspection findings and planned work.
- Rates, insurance, utilities and other ownership costs should be checked for the specific property.
- Unit-title owners pay body corporate levies; amounts and future changes depend on the development’s budgets, funds and planned work.
- Major repair scope and cost depend on the property’s condition and the work required.
- A household budget can include a contingency for unplanned property costs, sized to the property and the owner’s circumstances.
The mortgage payment is just the beginning. Many new homeowners are caught off guard by the cascade of additional expenses that come with property ownership. Knowing what to expect helps you budget properly and avoid financial stress.
When you are calculating whether you can afford a home, it is tempting to focus on the mortgage payment and assume everything else will work itself out. This approach leads many homeowners into difficulty when they discover that rates, insurance, maintenance, and unexpected repairs add substantially to their monthly outgoings. Understanding these costs upfront helps you buy within your true means and avoid the stress of stretching too thin.
Council Rates and Water
Council rates and water charging arrangements vary by council and property. Check the relevant council’s current property record, rating year and any separately billed water or targeted charges rather than relying on a generic national range.
Rates are an ongoing ownership cost, but future changes depend on the council’s adopted plans and rating decisions. Use the current bill or council property search for today’s amount and allow for uncertainty rather than assuming a particular annual increase.
Before buying, check the current rates for any property you are considering. The real estate listing should include this information, or you can find it on your council website. Significant differences between similar properties can occur based on specific location factors, so do not assume you know what rates will be based on neighbouring properties.
Insurance Costs
A lender may require house insurance as a condition of a home loan. Availability, cover, exclusions, excesses and premiums are property- and insurer-specific, particularly where natural-hazard risk is relevant, so confirm the lender’s requirements and obtain quotes before committing.
There is no reliable national premium range for a “typical” home. Obtain property-specific quotes and compare the sum insured, exclusions, excesses and conditions; some locations or construction features may affect availability or terms.
Insurance costs have become a significant factor in property affordability calculations. Before committing to a purchase, get insurance quotes to understand what you will actually pay. Some properties that seem affordable based on purchase price become much less so when insurance costs are factored in.

Maintenance and Repairs
This is where many homeowners underestimate costs most dramatically. When you rent, the landlord handles repairs. When you own, every blocked drain, broken appliance, and weathered fence is your problem and your expense. Small repairs add up quickly, and major repairs can run into tens of thousands of dollars.
Roofing, plumbing, wiring and foundation work can be significant, but whether it is needed—and its scope, timing and cost—depends on the property. Use inspection findings, maintenance records and qualified quotes for realistic planning.
Instead of relying on a fixed percentage of property value, build a maintenance allowance from the home’s age and condition, inspection findings, known service lives and planned work. Review the allowance as new information or repairs arise.
Body Corporate and Unit Title Costs
If you buy a unit title, body corporate levies are an ongoing cost. What they fund—including insurance, operations, common-property maintenance and long-term maintenance arrangements—depends on the development’s current budget, decisions and governing documents.
Levy amounts and future changes are development-specific. Planned work, operating costs, insurance and the relationship between the long-term maintenance plan and available funds can affect future contributions or additional levies.
Before buying a unit title, review the current disclosure material with your lawyer, including levies, accounts, meeting minutes, planned work and the long-term maintenance plan and fund. Check whether known work or funding gaps could change future contributions.
Utilities and Services
Moving from a rental to your own home often means moving to a larger space, which typically comes with higher utility costs. Electricity, gas, internet, and rubbish collection add up. If your new home has a larger garden, factor in the cost of maintaining it yourself or paying someone else to do so.
Some costs catch new homeowners by surprise because they were included in their previous rent. Separate water meters, garden maintenance, and shared facility costs are examples. Make sure you understand exactly what ongoing services your new property requires and what they will cost.
The total picture of homeownership costs extends well beyond the mortgage payment. Adding up rates, insurance, maintenance provisions, utilities, and any body corporate fees gives you a realistic view of what owning a particular property will actually cost. Only by understanding this full picture can you make an informed decision about what you can genuinely afford, rather than discovering too late that your dream home comes with nightmare expenses.
