How to Budget for Buying a Home in Australia: A Practical Financial Plan

Buying a home is not one transaction. It is a sequence of financial commitments that begins with saving a deposit and extends decades into the future. Approaching it without a complete budget is one of the most reliable ways to end up financially stretched after settlement, unable to absorb unexpected costs or build savings alongside your mortgage.

This guide builds a complete budgeting framework for Australian home buyers, from the saving phase through to the ongoing costs of ownership.

Phase 1: Pre-Purchase Budgeting

Know Your Target Number

Before you can save effectively, you need to know what you are saving toward. That means understanding not just the deposit but every cost associated with purchasing.

Work out your property price target based on your borrowing capacity. Use the free Purchasing Power calculator at HomeLoanTools.com.au to determine what price range is realistic for your income and deposit.

Then add the following costs to your deposit figure.

Stamp Duty

Stamp duty is typically the largest upfront cost outside the deposit itself. It varies significantly by state and by whether you qualify as a first home buyer.

Run your specific figures through the Stamp Duty Calculator at HomeLoanTools.com.au to get an accurate figure. In states like NSW and Victoria, first home buyers can save tens of thousands on stamp duty through concessions and exemptions.

Conveyancing and Legal Fees

A licensed conveyancer or solicitor manages the legal side of your property purchase: reviewing contracts, conducting title searches and handling settlement. Budget $1,200 to $2,500 depending on the complexity of the purchase.

Building and Pest Inspection

Commissioning an independent building inspection before you commit to a purchase is essential. Budget $400 to $800 for a combined building and pest inspection report.

Lenders Mortgage Insurance (if applicable)

If your deposit is under 20 per cent and you are not accessing a government guarantee scheme, LMI will apply. This can range from a few thousand to $20,000 or more depending on the loan size and LVR. Use the LMI estimate in your total funds calculation.

Lender Application and Establishment Fees

Some lenders charge upfront application or establishment fees. These range from zero to around $600. Check the fees for any lender you are considering.

Removalist Costs

Moving is not free. A local move with a professional removalist runs $800 to $2,500 depending on the volume and distance. Interstate moves cost considerably more.

Council and Utility Connection Fees

Connecting utilities, updating council rates records and other administrative costs at the new property add another few hundred dollars.

Emergency Buffer

Build in a buffer of $3,000 to $5,000 beyond your calculated purchase costs for unexpected expenses. Properties rarely transfer without any surprises.

Phase 2: Post-Settlement Budget

Many buyers focus intensely on saving the deposit and meeting purchase costs, then find themselves surprised by the ongoing monthly cost of ownership. These costs need to be built into your budget before you buy, not discovered afterward.

Mortgage Repayments

Your largest ongoing housing cost. Use the Loan Repayment calculator at HomeLoanTools.com.au to calculate your exact monthly repayment at current rates.

Budget also for the possibility of rate rises. If your loan is variable, model what your repayment would be at one per cent above the current rate. If that figure is comfortable in your budget, you have adequate buffer.

Council Rates

Council rates vary by property and local government area. Most residential properties attract annual council rates of $1,200 to $3,000. These are typically paid quarterly.

Water Rates

Water service charges are paid quarterly. Budget approximately $200 to $400 per quarter depending on your usage and location.

Home and Contents Insurance

Building insurance is essential (and typically required by the lender). Contents insurance is strongly recommended. Combined home and contents insurance typically costs $1,500 to $3,000 per year depending on the property value and location.

Strata Levies (Apartments and Townhouses)

If you buy in a strata scheme, quarterly levies cover building insurance, common area maintenance and the sinking fund. These range from $400 to $2,000 per quarter or more depending on the complexity of the development.

Maintenance and Repairs

Property maintenance is an ongoing cost that many first-time owners underestimate. A reasonable rule of thumb is to budget approximately one per cent of the property value per year for maintenance. On a $700,000 home, that is $7,000 per year as a long-term average, though actual costs will vary widely from year to year.

Land Tax (for Investment Properties)

If you buy an investment property, land tax will apply in most states once your total land value exceeds the applicable threshold. See our dedicated land tax guide for state-by-state details.

Building Your Budget Before You Buy

Step 1: Identify your target purchase price using the Borrowing Capacity and Purchasing Power calculators.

Step 2: Calculate total upfront costs using the Stamp Duty Calculator and the estimates above.

Step 3: Calculate ongoing monthly costs and confirm they fit within your budget with a comfortable buffer.

Step 4: Compare your total ongoing housing cost to your current rent. A significant increase is normal, but it should be an increase you can comfortably absorb.

Step 5: Factor in the rate buffer. Run the same calculation with the current rate plus one per cent. Make sure the budget still works.

The Budget Stress Test

Before you commit to any property, apply a simple stress test to your budget. Ask: if my income dropped by 20 per cent for three months, could I continue to meet my mortgage and essential costs?

If the answer is no, either your emergency fund is not adequate or the loan commitment is at the limit of what is prudent. Addressing this before purchase is far better than discovering it under pressure.
