The New Policy Landscape
As of February 1, 2026, lenders face a hard mandate: residential mortgage lending with a DTI ratio of six (6) or higher cannot exceed 20% of their total new mortgage lending.
Crucially, this cap is applied separately to owner-occupier and investor portfolios. This creates a scenario where high-geared investors, despite holding strong equity, may face sudden credit declines as lenders rapidly manage their internal pipeline allocations.
The Strategic Imperative
DTI limits are now "guardrails, not handbrakes." Broker success fundamentally depends on structuring deals to safely navigate within these bounds or identifying legitimate exemptions before submission.

APRA Implementation Settings (2026)
Detailed matrix of how the rules apply across different market segments and lending institutions.
| Segment | DTI Threshold | Lending Cap | Measurement Basis | Key Exemptions |
|---|---|---|---|---|
| Major Banks (SFI) | ≥ 6x | 20% | Quarterly basis | New Build, New Dwellings, Bridging |
| Smaller Banks (Non-SFI) | ≥ 6x | 20% | 4-Quarter Rolling | Optional carve-outs to streamline data |
| Owner-Occupiers | N/A | N/A | Separate Portfolio | Primary Residence Transfer (12 months) |
| Investors | N/A | N/A | Separate Portfolio | None explicitly beyond construction |
The Strategic Broker Playbook
Explore actionable frameworks to navigate the new lending environment, secure approvals, and advise clients effectively. Select a strategy below.
Step 1: Bypassing Caps via Housing Supply
To align with national goals of increasing housing supply, APRA has explicitly exempted specific loan types from the DTI ≥ 6 limits. This is your primary lever for highly leveraged clients.
Eligible Exemptions
- Finance for the construction of new dwellings.
- Purchase of newly erected properties.
Client Conversation Example
"Given your current equity and the new DTI limits on existing properties, our strongest path to approval without hitting bank caps is to pivot this investment toward a new build or off-the-plan property."
Step 2: Strict Limit Management
When an exemption isn't possible, the goal is to drive the calculated DTI down. A DTI of 5.95 is approved under standard policy; a DTI of 6.01 enters the constrained 20% bucket.
Rental Yields
Ensure current market rental appraisals are used, not historical lease data, to maximize the 'Income' denominator of the ratio.
Secondary Income
Rigorously document bonuses, overtime, or secondary employment. Understand which lenders 'shade' this income the least.
Conduct pre-assessments meticulously. The margin for error on income documentation has vanished. Every dollar counts toward staying under 6.0.
Step 3: Utilizing Alternate Channels
APRA's mandate directly governs Authorised Deposit-taking Institutions (ADIs). Many non-bank lenders operate under different regulatory frameworks and funding structures.
The Non-Bank Opportunity
While non-banks strictly adhere to responsible lending (NCCP), they are not bound by the same arbitrary 20% volume cap on DTI > 6 as APRA-regulated entities. They have more flexibility in pricing risk.
Strategic Pivot Script
"The major banks have hit their regulatory ceiling for high-leverage lending this quarter. However, I have pre-vetted two non-bank lenders who specialize in your profile and aren't restricted by these specific volume caps."
Step 4: Navigating Complex Entities
Under the new regime, lenders are looking closely at the total debt versus income position. This brings complex entity structures, particularly trusts, under intense scrutiny.
- Discretionary Unit Trusts: Expect extreme difficulty in carving out debt held in trusts from personal liabilities when lenders calculate the final DTI.
- Beneficiary Assessment: Lenders will place significantly heavier weight on the proportional debt of beneficiaries.
Engage earlier with clients' accountants. Clean structures and crystal-clear historical profit distributions are now mandatory for credit assessors.
Turn Policy Into Advantage
The 20% DTI cap is a structural shift in Australian lending. Brokers who proactively reassess their strategies, understand lender nuances, and utilize the frameworks above will gain a distinct competitive edge.
