Am I in Mortgage Stress? Signs, Thresholds, and What to Do Next

Mortgage stress is no longer an edge case in Australia. With the national mortgage serviceability ratio at 45.9% of gross household income and the RBA raising rates twice in early 2026, approximately one in four Australian mortgage holders is now classified as being at risk. If you are feeling financial pressure from your home loan, this guide explains what stress actually means, how to diagnose your own position, and what options are available.

What Is Mortgage Stress?

The standard definition of mortgage stress is spending more than 30% of gross household income on mortgage repayments. This 30% benchmark is used by researchers, financial counsellors, and housing policy makers as the threshold above which repayments begin to crowd out other essential spending.

By this measure, national average repayments of $4,180 on average gross household income represent approximately 34–45% of income depending on the household, placing most new borrowers in stress territory from day one of their loan.

Signs You Are Under Mortgage Pressure

• Regularly using a credit card or BNPL to cover everyday expenses because monthly cash flow is negative
• Skipping or deferring other savings contributions (emergency fund, superannuation) to make repayments
• Difficulty absorbing unexpected expenses — car repair, medical bill, appliance replacement — without going into debt
• Mental health impact — persistent stress, loss of sleep, or relationship strain related to the mortgage
• Having no financial buffer — if you lost your income tomorrow, you have less than one month of repayments in savings

Your Options If You Are in Mortgage Stress

1. Call your lender before missing a payment

Australian banks are required under the Banking Code of Practice to assist customers experiencing genuine financial hardship. Calling before you miss a payment — rather than after — gives you significantly more options. Hardship arrangements can include temporary repayment deferrals, interest-only periods, or loan restructuring. These do not automatically appear on your credit file if handled proactively.

2. Negotiate your interest rate

The gap between the best variable rates in the market and what loyalty customers pay at major banks is often 0.5–1.0%. On a $700,000 balance, this is $3,500–$7,000 per year. Call your bank and ask for a rate review. If they decline, get competing quotes from other lenders and use them as leverage. This one call can materially reduce your monthly repayment without refinancing.

3. Refinance to a lower rate or longer term

If your equity position allows (generally 20%+ to avoid LMI on refinance), switching lenders can reduce your rate significantly. Note that extending your loan term reduces monthly repayments but increases total interest paid — model both outcomes before deciding.

4. Switch to interest-only temporarily

Moving to an interest-only repayment temporarily reduces your monthly payment by eliminating the principal component. On a $600,000 balance at 6%, interest-only payments are approximately $3,000/month vs $3,861/month for principal and interest — a difference of $861/month. This is a temporary measure, not a solution, as the loan balance does not reduce during interest-only periods.

5. Rent out a room or space

Income from renting a room in your home is taxed as income but can provide meaningful monthly cash flow relief. In many Australian cities, a room rents for $200–$400 per week — $800–$1,600 per month that can be applied directly to mortgage repayments.

What Not to Do

• Don't ignore the problem: Missed repayments accumulate quickly. After 90 days of missed payments, lenders can begin default proceedings. Acting early preserves your options.
• Don't access superannuation early: Early super access is only available under specific compassionate grounds conditions — mortgage repayments generally do not qualify. Do not take advice from anyone suggesting you can access super to pay your mortgage.
• Don't use high-interest debt to cover repayments: Putting mortgage repayments on a credit card at 20% interest to bridge a shortfall creates a compounding debt trap.
