Mortgage stress is the pressure a household faces when home-loan repayments leave too little income for other living costs. Housing costs above about 30% of household income are a common rule of thumb, but a household can struggle below that level.
What Counts as Mortgage Stress
The 30% benchmark flags repayment pressure, while the household's remaining budget shows whether it can cope. It is a rule of thumb, not a legal test for hardship assistance.
The Australian Housing and Urban Research Institute (AHURI) explains the 30:40 housing stress indicator. It identifies households in the bottom 40% of the income distribution that spend more than 30% of income on housing costs. Those costs include mortgage principal and interest, rates, insurance and maintenance.
To calculate the housing-cost percentage, divide housing costs by household income for the same period, then multiply by 100.
The general 30% shorthand drops that lower-income condition. For example, a hypothetical household with $8,000 in monthly gross income and $2,600 in housing costs spends 32.5% on housing. That percentage alone does not establish whether it meets AHURI's income condition or can afford its other expenses.
Mortgage stress describes strain on the household. Two borrowers with identical loans can face different pressure because their incomes and other commitments differ.
Why Households Tip Into It
Mortgage stress develops when repayments and living costs outgrow the income available to pay them. Rate rises put particular pressure on a loan originally sized at the household's maximum borrowing capacity.
An income interruption, such as illness or job loss, can remove the money that previously covered repayments. When living costs also rise faster than pay, the household has less room to absorb either change.
To reduce the risk of mortgage stress, base your budget on take-home pay and actual expenses. Allow for irregular bills and build a savings buffer where your budget permits. Recheck affordability when income falls or repayments rise, before using credit to cover the shortfall.
In a soft housing market, selling may no longer produce the gain a borrower expected. Sale proceeds after costs may leave less money to clear debt or fund another home. See how Australian mortgage rates compare with past highs and lows for the wider rate context.
The Warning Signs Worth Watching
A client can be under mortgage stress while every home-loan repayment is still on time. Brokers reviewing statements and discussing the household budget can watch for these changes.
- Savings keep falling between repayments and are not rebuilt on payday.
- Credit-card or buy-now-pay-later use rises to cover everyday expenses.
- The client repeatedly asks to extend the loan term to reduce repayments.
- Payments on other loans or bills are missed while the mortgage stays current.
Ask what has changed in the client's income and spending when a warning sign appears. Establish whether the shortfall is temporary or continues each month. If repayments have already been missed, the guide to helping clients in mortgage default covers the broker's next steps.
Where Struggling Borrowers Turn
Contact the lender's hardship team as soon as repayments become unaffordable. Moneysmart's hardship guidance explains what to provide, including income, major expenses and an affordable repayment amount.
For loans covered by consumer credit law, section 72 of the National Credit Code governs hardship notices. The lender must consider the request and respond. A request can be made verbally or in writing. A particular repayment change is not guaranteed. The Australian Securities and Investments Commission (ASIC) explains these hardship notice obligations.
Mortgage stress relief can include a temporary payment pause or reduced repayments agreed with the lender. Ask how interest and missed amounts will be repaid before accepting an arrangement.
A free financial counsellor can help work out an affordable budget and negotiate with creditors. Call the National Debt Helpline on 1800 007 007 for help.
If the lender's response does not resolve the problem, use its complaints process. Unresolved hardship complaints can go to the Australian Financial Complaints Authority (AFCA), which provides a free dispute resolution service.
Whether Refinancing Helps
Refinancing helps when the new loan makes repayments affordable after switching costs, without creating an unsustainable debt burden. Ask the current lender about a lower rate before paying to move.
Compare the proposed repayment with the household's actual income and spending. Include switching fees and compare total interest over the remaining term. Moneysmart's switching guide explains how a longer term increases interest costs, even when the monthly repayment falls.
A borrower already behind on repayments may only qualify with specialist lenders at higher cost. Approval alone does not show that refinancing relieves mortgage stress. If the budget still runs short, pursue hardship assistance instead of treating another loan as the solution.
If other debts drive the shortfall, compare the costs and risks of debt consolidation loans before adding them to a mortgage. Review the home loan annually using today's rates and the household's current budget, and bring that review forward when a warning sign appears.
