Key Takeaway

Consolidating credit card and personal loan debt into a mortgage only makes sense when it reduces default risk, lowers interest costs over a 3–7 year horizon, and is locked into short, purpose-labelled splits instead of a new 25–30 year term. With around 28% of Australian mortgage holders already ‘At Risk’ of stress (Roy Morgan 2026), borrowers should model repayments at current rates plus 3% and close old limits. A clear repayment plan and spending reset are the actionable essentials.

Rolling credit cards and personal loans into your mortgage makes sense only when it cuts your risk of default, reduces interest over a realistic timeframe (say 3–7 years), and you keep the consolidated debt in short, separate loan splits rather than spreading it over 25–30 years. If you don’t close the old cards, fix your budget and stress‑test at higher rates, you’re usually just kicking the can and risking worse trouble later.

Quick test: does consolidating your debts actually help?

Before you touch your mortgage, run three tests.

Cashflow test – Will your total minimum repayments drop enough to get you out of crisis, not just feel a bit nicer?
Total interest test – Are you paying less interest over 3–7 years, once you include refinance costs?
Behaviour test – Are you closing the cards and changing habits, or just resetting the limit?

If you can’t honestly tick all three, rolling debts into your home loan is usually a bad trade.

When debt consolidation into your home loan makes sense

1. You’re close to the edge – and this clearly pulls you back With the cash rate sitting at 4.35% and around 28% of mortgage holders ‘At Risk’ of stress (Roy Morgan 2026), many households are one rate rise or one bad month away from default.

Frequently asked questions

No. While mortgage rates are lower, stretching short-term debts over 25–30 years can mean you pay more total interest than keeping them separate. It’s only cheaper if you use a short 3–7 year loan split and repay it aggressively, and if the savings clearly beat any refinance costs.

Your score may dip briefly due to the new credit enquiry, but closing unused cards and making consistent repayments usually helps over time. Problems arise when people keep old limits open, add new debts, or apply for multiple facilities in a short period.

Check that your total repayments fall to a level you can comfortably afford, even if interest rates rise by about 3%. Compare total interest over a 3–7 year period between staying as you are and consolidating, and only proceed if the new structure clearly wins and you’re closing old limits.
