CBA Forecasts Australia's Worst-Ever Housing Crash as CoreLogic Confirms National Downturn Broadens to Brisbane and Perth

Key takeaway: Commonwealth Bank — Australia's largest home lender — has revised its forecast to project the worst national housing value correction in Australian history (peak to trough), with Brisbane and Perth most exposed. CoreLogic's November 2026 data confirms the downturn is broadening beyond Sydney and Melbourne. For borrowers with existing loans, rising LVRs, tighter refinancing eligibility, and bridging loan strategy all require urgent review.

Two Reports That Have Shifted Australia's Property Consensus

Within days of each other, two separate market signals have dramatically changed the outlook for Australian property.

First, CoreLogic's November 1, 2026 analysis confirmed that Australia's housing downturn is broadening — moving beyond the southern capitals to encompass Brisbane and Perth, both of which had previously remained relatively resilient. CoreLogic now reports that Brisbane and Perth are leading the national decline.

Second, and more strikingly, Commonwealth Bank — Australia's largest home lender — has revised its internal property forecasts to tip what it describes as the worst national housing value correction in Australian recorded history, measured from peak to trough. CBA specifically identifies Brisbane and Perth as the most exposed markets in this cycle.

Both signals arrive as the RBA cash rate reaches 4.85% (effective 4 November 2026), with inflation still running at 4.3% (ABS, September 2026) and the economy growing at a modest 0.4% quarterly rate (ABS, June 2026).

What Falling Property Values Mean for LVR and Lending

For borrowers with existing mortgages, falling property values have a direct mechanical effect: the loan-to-value ratio (LVR) rises as the property value falls. This matters in several specific scenarios:

Refinancing: A borrower who previously had 30% equity may now have 20% or less, which can affect the interest rate tier offered, mortgage insurance requirements, and the lender's willingness to approve the refinance.

Bridging loans: Borrowers planning to sell their current property before purchasing a new one may find the expected sale proceeds are lower than anticipated, affecting the bridging loan's peak debt calculation and exit strategy viability.

Commercial property: Commercial LVRs are already conservative at non-bank lenders (typically 65–75%). A sustained residential market correction often precedes softening in commercial property values, making a review of existing commercial loan structures worthwhile.

Why a Downturn Accelerates Demand for Non-Bank Lending

Counterintuitively, falling property values tend to drive a surge in non-bank lending applications — particularly among borrowers who fear their LVR will breach a threshold triggering changes to loan terms, or who need to act before their property value declines further.

Major banks become more conservative in both property valuations and serviceability assessments during downturns. The very moment borrowers most need flexible lending, Big Four criteria tighten. Independent valuations used by non-bank lenders, and commercial assessment of a borrower's real capacity rather than a blanket market discount, can make a meaningful practical difference for borrowers in Brisbane, Perth, or other softening markets.

For property developers in Queensland or Western Australia, the combination of a cooling residential market and a rising cash rate creates a particularly challenging financing environment. Developers who locked in site costs at peak values may now face LVR shortfalls that standard bank finance cannot resolve.

What This Means for Borrowers — The MPFG View

MPFG Capital works with borrowers in exactly this type of market environment. If you're a Queensland investor whose property value has declined and you need to refinance before LVR terms are triggered, a property developer seeking construction or bridging finance in a softening market, or a self-employed borrower navigating increasingly conservative bank assessments — MPFG has structured lending solutions calibrated to real market conditions.

For borrowers weighing a property sale during the current correction, MPFG's bridging finance allows you to manage the timing gap between sale and purchase without being forced into a distressed sale. Bridging finance can protect your exit strategy even when valuations are moving against you.

FAQ

What does CBA's "worst-ever housing crash" forecast mean for my mortgage?

CBA's revised projection places this correction — from peak to trough — as larger than any previous national housing downturn on record in Australia, with Brisbane and Perth most at risk. For existing borrowers, the primary concern is a rising LVR as property values fall, which can affect refinancing eligibility, interest rate tiers, and lender conditions. Reviewing your current LVR position with a broker is recommended now.

How does a falling property market affect bridging loan applications in Brisbane or Perth?

In a declining market, lenders assess bridging loan applications more conservatively because the security property's sale price may come in below previous estimates. A clear exit strategy — such as a signed sale contract or pre-approved purchase — becomes essential. Non-bank lenders like MPFG apply commercial judgement to bridging structures rather than applying standard market discount assumptions, which can make approval more accessible.

Should I sell my investment property now if Brisbane and Perth values are falling?

This depends on your individual LVR position, rental yield, tax circumstances, and cash flow — not general market direction alone. We strongly recommend speaking with your mortgage broker and financial adviser before acting. What MPFG can assist with is the financing structure: if you need timing flexibility, bridging finance can allow you to purchase before your sale completes, without forcing a distressed exit.
