How to avoid mortgage stress when buying your first home

For many Australians, buying a first home is one of life’s biggest milestones. But for some buyers, that excitement can quickly turn into financial pressure. 

Research from Roy Morgan shows around 24.5 per cent of Australian mortgage holders are currently considered “at risk” of mortgage stress, a reminder that affordability remains a very real challenge, especially after the RBA hiked rates in February.

However, mortgage stress, defined as spending more than 30 per cent of gross household income on home loan repayments, rarely begins when interest rates rise. More often, it starts the moment the purchase decision is made.

Typically, buyers struggle because they stretched too far to secure the wrong one. If you want to avoid mortgage stress, the most important decisions happen before you sign the contract.

Don’t borrow your maximum, borrow your margin 

Banks calculate how much you can borrow, but that number is not a recommendation. It is simply the upper limit. One of the most common mistakes first-home buyers make is purchasing right at their borrowing ceiling. The loan may be approved on paper, yet it often leaves little room for changes in interest rates, employment or life circumstances.

A sensible approach is to model repayments assuming at least two or three additional rate rises. If your budget only works at today’s rates, it is already too tight. Buying below your maximum creates breathing space, protects your lifestyle and reduces the risk that a rate movement or income change forces you into a tough financial position.

 

Where buyers go wrong

The biggest mistakes are rarely mathematical. They are emotional. Buyers often become attached to a version of their dream home that does not align with their financial position. It might be a renovated kitchen, an extra bedroom or simply the prestige of a certain suburb. Once emotion takes over, the numbers tend to follow.

Sometimes the smarter move is buying slightly further out, choosing a smaller property or accepting some compromises. Stretching for a home you love can translate into years of financial pressure.

 

Build a three to six month buffer

Liquidity is one of the most overlooked protections against mortgage stress. Before settlement, aim to hold at least three to six months of mortgage repayments and essential living expenses in an offset account. This buffer acts as a shock absorber if something unexpected occurs, whether that is a job change, parental leave, illness or a major repair.

Households relying on dual incomes should consider what happens if one income temporarily gets cut. Commission-based earners should assume there will be bad times as well as good. Planning prevents reactive decision-making later on.

Understand the true cost of ownership

Many first-home buyers budget carefully for repayments but underestimate the ongoing cost. Property expenses extend well beyond the mortgage. There are council rates, insurance, maintenance, strata levies, repairs and upgrades.

A freestanding home may require roofing, plumbing or fencing work over time. Apartments can face special levies for building repairs. These costs are normal, but they need to be planned for. Including a maintenance allowance in your affordability calculations helps avoid unpleasant surprises.

 

Consider rentvesting if necessary

If the only property you can afford in your preferred suburb is a weaker asset, such as a high-rise apartment in an oversupplied area with limited growth prospects, it may be worth reconsidering your approach. Rentvesting allows you to rent where you want to live while purchasing an investment-grade property in a more affordable, high-demand location.

This strategy can reduce mortgage pressure while improving asset selection and maintaining lifestyle flexibility. Home ownership alone does not create wealth. Buying good assets does.

 

Buy with fundamentals, not fear

Open homes and auctions are designed to create urgency. Competition builds, and buyers can feel pressured to act. Mortgage stress often begins with a split-second decision to exceed a carefully planned budget.

Before entering negotiations, determine your price ceiling in a calm environment and commit to it. Focus on fundamentals like areas with strong owner-occupier demand, constrained supply, access to infrastructure and steady population growth tend to provide greater growth over time.

Your first home should provide stability, not anxiety. Mortgage stress is rarely about property itself.

It usually comes down to preparation and decision-making at the outset. Buyers who plan, build financial buffers and keep emotions in check significantly reduce their risk of ending up feeling the pressure of their mortgage.
