Before You Start Inspecting, Work Out the Budget That Still Lets You Breathe

The budget conversation becomes more useful when it moves from "what can we borrow?" to "what would this purchase ask from us?"

A good buying range is built from five numbers, but the point is not to fill in a neat worksheet and move on. Each number should change how you search, which properties you take seriously, and where you stop when the pressure starts.

Start with the lender or broker estimate, then pull it apart a little. A number from a broker can be useful, but it is worth knowing whether it is a rough borrowing estimate, a conditional pre-approval, or something that still needs more verification. Ask what income, expense and deposit assumptions were used. Ask whether the figure depends on a particular lender, loan product, income treatment or declared expense position. A buyer with overtime, bonus income, self-employed income, family support or recent job changes may find that one lender's answer is not the whole market's answer.

That number helps you understand the outer edge. It should not become the target by default.

Then work backwards from the repayment you would actually want to live with. Look at the monthly repayment at a few purchase prices, including the one you hope will work. Put those repayments beside your current spending and the spending you know is coming: childcare, school costs, insurance, medical costs, car costs, family support, travel, or a period of lower income. MoneySmart suggests buyers look at what their costs would be if interest rates rose. That exercise is useful because it shows whether the budget still works when conditions are less friendly, rather than only when the calculator is set to today's rate. [2]

The third number is the cash needed to get the deal done. The deposit is only the obvious part. Buyers also need to allow for conveyancing or legal fees, lender costs, government charges, building and pest inspections, owners corporation checks where relevant, moving, utility connections, basic furniture and the first wave of repairs or setup. A buyer can technically have enough deposit and still feel cash-poor after settlement if these costs were treated as an afterthought. [4]

Then look at the property type. A house, townhouse, apartment and older unit can carry very different ownership costs. Council rates, insurance, utilities, maintenance, garden care, appliance replacement and owners corporation fees all sit outside the purchase price. So does the condition of the property. A cheaper home that needs roof work, drainage attention, rewiring, restumping, new appliances or immediate cosmetic work may not be cheaper in the way it first appears.

The final number is the one buyers often leave too vague: what cash do you want left after settlement?

There is no universal answer. But "whatever is left" is a weak plan. A first home buyer with stable income and no dependants may be comfortable with a smaller buffer than a family with children, a buyer planning renovations, someone with variable income, or someone supporting relatives. The buffer should reflect the life you are protecting as well as the property you are trying to win.

Once those five numbers are on the table, your budget becomes more than a maximum. It becomes a set of rules for the search. If a property needs work, you know what that does to the buffer. If the owners corporation fees are high, you know what that does to the monthly comfort number. If the agent is pushing you another $20,000 above your preferred range, you know exactly what trade-off you are being asked to accept.

That is the insight buyers need before the property feels personal. The right number has to get you into the home and still make sense after the keys are in your hand.
