Breaking Out of “Mortgage Prison”: Can Easing Serviceability Buffers Help?
Told you can’t refinance, even though rates elsewhere look sharper? You’re not alone. Many households are stuck in “mortgage prison” after rapid rate rises. The good news: some banks have temporarily eased serviceability buffers for certain refinance cases, which may open a path to savings (with trade-offs to consider).
Why So Many Borrowers Are Stuck
Refinancing surged as rates climbed, ABS reported a record $21.3B in March 2023, up 14.2% year-on-year. Yet plenty of people can’t switch because of the serviceability buffer: lenders must “stress-test” new applications 3% above the actual rate, even for refinances. After the cash rate jumped from 0.10% to 4.10% in ~13 months, many borrowers no longer pass the standard test.
APRA’s guidance allows case-by-case exceptions for complex files. Recently, CBA and Westpac (plus Westpac brands St.George, Bank of Melbourne, BankSA) introduced streamlined refinance settings using a ~1% buffer for eligible borrowers.
Bottom line: a reduced buffer may help some borrowers qualify to refinance, but criteria apply and there can be long-term cost trade-offs.
What Is “Mortgage Prison”?
It’s when your current rate is hurting cash flow, you can likely save by switching, but you fail the serviceability test with other lenders, so you’re effectively stuck on your existing loan.
Who Might Qualify Under Eased Buffer Policies?
Criteria vary by lender. Example settings (summarised from your article):
- CBA:
- LVR ≤ 80%
- Clean repayment history on all debts in the last 12 months
- Refinance to P&I with a similar or lower loan amount
- Must still pass the ~1% buffer
- Westpac (streamlined refinance):
- Credit score > 650
- 12-month clean repayment record
- New loan has lower monthly repayments than current
- Must pass the ~1% buffer
Policies can change and not all scenarios are eligible. We’ll confirm current criteria and participating lenders for your file.
The Catch: Lower Repayments Now, More Interest Later
Some offers reset the term (e.g., out to 30 years). That can cut repayments today but increase total interest.
Your example: on a $500,000 loan, repayments could fall ~$235/month, but extending the term by ~3 years may add ~$32,117 in total interest over time.
How we weigh it:
- Short-term relief vs long-term cost
- Whether a partial term reset or higher ongoing extra repayments can offset added interest
- A plan to refinance again or reprice once your position improves
Are Eased Buffers Right For You?
They can be, if they genuinely improve cash flow and you have a plan to reduce the extra interest cost. We’ll help you:
- Test your file under standard vs eased buffers
- Compare like-for-like rates, fees and features (offset/redraw)
- Model repayment impact and lifetime cost
- Map a de-risk path (e.g., debt reduction, credit clean-up, LVR targets) and a refinance timeline

FAQs
What is a serviceability buffer?
A margin lenders add to the interest rate when assessing your affordability (commonly +3%). It helps ensure you can cope with higher rates.
Why do some lenders use ~1% for certain refinances?
Under APRA’s case-by-case exception guidance, some lenders offer a streamlined refinance path to reduce hardship risks, subject to strict eligibility.
Will I have to extend my loan term?
Often that’s part of the offer to lower repayments. It can increase total interest. We’ll model alternatives (shorter terms, extra repayments) to control cost.
Can I still switch if my LVR is above 80%?
Possibly, but options narrow and pricing may rise. Hitting ≤80% LVR usually improves lender choice and rates.
What else improves my refinance odds?
Stable income, clean 12-month repayment history, lower unsecured limits, and realistic living expenses all help pass serviceability.
