A Sydney property price can make a first home feel like a single, intimidating number. It is not. A useful first home buyer budget example separates the purchase into manageable parts: the cash you need before settlement, the loan you can comfortably repay, and the costs that arrive after you get the keys.
That distinction matters. Having enough for a deposit does not automatically mean a property is affordable, and a lender’s maximum approval is not necessarily a comfortable household budget. The right figure is the one that leaves room for your life, not just your mortgage.
A first home buyer budget example: buying at $850,000
Let’s assume you are buying an established home or apartment in Sydney for $850,000. You have saved $115,000 and plan to use a 10 per cent deposit. This is a realistic starting point for many buyers, but it comes with different costs and risks than a 20 per cent deposit.
Your 10 per cent deposit is $85,000. Depending on your circumstances, you may be eligible for a government guarantee or a NSW first-home buyer duty concession. Eligibility rules, price caps and available places can change, so treat these as possibilities to confirm early rather than money to count on.
If you are not eligible for an exemption or concession, transfer duty can be one of the largest upfront costs. On an $850,000 purchase, allow roughly $33,000 as a planning estimate, then obtain an up-to-date calculation before making decisions. Add conveyancing and legal work of around $2,000 to $3,500, building and pest inspections of approximately $500 to $900, and loan application, valuation or settlement charges where applicable.
A practical upfront budget might look like this:
- Deposit: $85,000
- Transfer duty planning allowance: $33,000
- Conveyancing, searches and settlement costs: $3,000
- Building and pest inspection: $700
- Lenders mortgage insurance or guarantee-related costs: $0 to $20,000-plus
- Moving, connection and immediate home costs: $4,000
- Contingency buffer: $8,000
That puts the cash required at roughly $133,700 before any lenders mortgage insurance. With $115,000 saved, this buyer may need to lower the purchase price, build savings further, use an eligible scheme, receive family support, or adjust the deposit strategy.
The key lesson is not that every buyer needs the same amount. It is that the advertised price is only the first line of the budget.
Deposit size changes more than the upfront figure
A 20 per cent deposit on the same $850,000 property is $170,000. It can remove the need for lenders mortgage insurance and reduce the size of the loan, but it also takes longer to save. In a market where prices or rents are moving, waiting may have a cost of its own.
With a 10 per cent deposit, the loan is $765,000 before any loan costs added to the balance. With a 20 per cent deposit, it is $680,000. The larger loan means higher repayments and less flexibility if rates rise, but buying earlier can still be sensible for a buyer with stable income, a secure buffer and a property that suits their medium-term plans.
This is where generic rules can be unhelpful. A 20 per cent deposit is a strong position, not a universal requirement. Equally, a smaller deposit is not automatically a shortcut worth taking. It needs to be supported by realistic repayments and a clear plan for the additional purchase costs.
Do not spend every dollar at settlement
A common first-home buyer mistake is treating every saved dollar as deposit money. Keep funds aside after settlement for the expenses that do not wait politely.
Your first rates notice, strata levies, insurance premium, appliance replacement or urgent repair may turn up sooner than expected. Even an apartment with a healthy strata report can need new furniture, blinds or a removalist. For a house, a leaking tap, ageing hot-water system or neglected garden can quickly test a tight budget.
As a guide, retaining three to six months of essential expenses is ideal, although the right buffer depends on job security, dependants, health needs and whether one or two incomes support the loan. A smaller buffer may be workable in a dual-income household with stable employment. It is more risky for a single buyer with variable income.
Test the monthly budget, not just the loan approval
Now consider the ongoing costs of our $850,000 example. A $765,000 loan over 30 years can create a substantial monthly commitment. Your actual repayment depends on the interest rate, loan type and features, but it is wise to test your budget at both the current quoted rate and a higher rate.
Rather than asking only, “Will the bank lend me this?”, ask, “Can we still manage if repayments increase, work slows down or the car needs replacing?” A lender will assess your living expenses and liabilities, but your own budget should be more personal and more conservative.
Start with your net household income, then account for regular spending: groceries, transport, mobile plans, private health cover, childcare, subscriptions, dining out, pets, debt repayments and savings. Include property costs that may not be in your current rental budget, such as council rates, water charges, home insurance and strata levies.
For an apartment, strata fees deserve close attention. They can vary significantly according to the building’s facilities, age and maintenance needs. A lower purchase price with high quarterly levies may be less affordable than a slightly dearer property with modest running costs. For a freestanding home, allow more for maintenance because there is no owners corporation sharing the cost of the roof, exterior or grounds.
Costs to investigate before you make an offer
The strongest budgets are based on the specific property, not broad averages. Before offering, review the contract and request clarity on costs that will affect your cash position or monthly spending.
For a strata property, check the levy amount, capital works fund, recent meeting minutes and any proposed special levies. A building with major repairs ahead can change the value of a seemingly affordable unit. For a house, consider insurance availability, flood or bushfire exposure, drainage, roof condition and likely maintenance.
You should also budget for the settlement adjustment. Depending on the timing, you may reimburse the seller for a portion of council rates, water charges or strata levies already paid. It is usually not the largest expense, but it is still part of the final amount your conveyancer will outline.
If you are buying at auction, have your finance position, contract review and inspection completed beforehand. There is generally no cooling-off period after a successful auction bid in NSW. A disciplined maximum price protects you from making a costly decision in a competitive moment.
Set a purchase ceiling before inspections become emotional
Your borrowing capacity is a starting point. Your purchase ceiling should reflect the total cost of ownership and the lifestyle you want to maintain.
One helpful approach is to set three figures. The first is your ideal purchase range, where repayments and savings remain comfortable. The second is a stretch range, used only for a property that genuinely meets long-term needs. The third is a firm walk-away price that includes duty, fees, likely repairs and your minimum cash buffer.
For example, a buyer with $115,000 saved may find that $850,000 is possible only with a concession or guarantee. If neither applies, a lower purchase price could preserve the emergency fund and reduce the pressure to add every cost to the loan. That is not a compromise in ambition. It is a decision that gives your first home a better chance of remaining a positive financial step.
Make the budget fit your next move
A first home does not need to be your forever home. For some Sydney buyers, an apartment close to work offers a manageable entry point. For others, a townhouse further from the CBD delivers more space and a different lifestyle. Rentvesting can also suit buyers who want to enter the market while continuing to rent in an area that better fits their work or family life.
The best choice depends on your timeframe, commute, household plans and appetite for maintenance as much as the headline price. Your Next Move Real Estate can help buyers assess local options with the full costs and practical trade-offs in view. A well-built budget gives you permission to act with confidence when the right property appears, and to walk away when it does not.
