How much is sustainable?

Determining a manageable mortgage payment is essential for long-term financial stability. A healthy budget protects you from mortgage stress and leaves room for savings, lifestyle and unexpected expenses. What defines a sustainable payment?

  • A balanced portion of income: Housing costs should remain within a reasonable share of your gross income.

  • Room for other commitments: Borrowing decisions must account for debts, living expenses and future financial goals.

  • Buffer for changes: A sustainable amount considers possible rate increases and lifestyle changes.

Lenders use internal formulas to measure affordability, not just simple percentages. HeyNest brokers assess both your ideal budget and lender requirements, helping you secure a repayment that fits comfortably into your life.

Lender serviceability: the stress test

Banks don’t only evaluate what you can afford today, they assess whether you could continue repayments if rates rise or your expenses change. This “stress test” protects both borrowers and lenders. What lenders assess:

  • Higher hypothetical rate: Applications are calculated using a rate above market levels to ensure resilience.

  • Living expenses: Banks review actual spending alongside benchmark measures to evaluate disposable income.

  • Total debts: Credit cards and loans are counted toward potential obligations, not just what you currently owe.

Passing this test is crucial for loan approval. HeyNest brokers pre-assess your application across multiple lenders, identifying which one is most aligned with your profile before you apply.

Optimising your percentage for financial freedom

Managing your mortgage isn’t just about meeting a safe income percentage, it’s about reducing it over time through smart loan features and strategies. Ways to lower your long-term burden:

  • Offset accounts: Reduces the interest charged by lowering the effective loan balance.

  • Extra repayments: Payments above the minimum directly shrink the principal and cut future interest.

  • Choosing the right structure: Fixed, variable or split loans offer different benefits in repayment flexibility and stability.

The goal is not just affordability today but financial freedom tomorrow. HeyNest connects you to brokers who tailor loan features and structures to reduce what you pay over the life of your loan, helping your mortgage support your financial goals, not limit them.

Frequently asked questions

What is 'mortgage stress' in Australia?

It's generally defined as spending over 30% of your gross income on home loan repayments, often indicating financial difficulty.

Is 40% of my income too much for a mortgage?

Yes, while some lenders may approve it, 40% is high and increases the risk of financial strain, especially if interest rates rise.

Does this percentage apply to my gross or net income?

Lenders primarily use your gross income (before tax) for their serviceability calculations.
