How Lender Policy Changes Are Impacting Mortgage Applications in Australia

How Lender Policy Changes Are Impacting Mortgage Applications in Australia

If you are a mortgage broker in Australia right now, you already know the feeling. A client who would have sailed through an approval process twelve months ago is now facing questions, delays, and in some cases, outright declines. The loan has not changed. The client has not changed. But the lender policies have.

Across Australia, major banks, regional lenders, and non-bank institutions are all updating their credit policies at a pace that is challenging even the most experienced brokers to keep up with. Understanding what has changed, why it has changed, and how to work within the new rules is now one of the most valuable skills a mortgage broker can offer.

With mortgage brokers now writing more than 80% of all new residential home loans in Australia, the brokers who master this skill have an enormous market opportunity and those who don't risk losing clients to competitors who do.

This guide breaks down the most significant lender policy changes impacting mortgage applications right now and gives your brokerage a clear, practical playbook to adapt.

Why Lender Policies Are Changing So Rapidly

Lender credit policies do not change in isolation. They respond to a combination of regulatory pressure, economic conditions, and risk appetite shifts within individual institutions.

The key drivers behind the current wave of policy changes include:

• APRA's new debt-to-income (DTI) lending cap, which limits banks to writing no more than 20% of new home loans to borrowers with a DTI ratio of six times income or higher applied separately across owner-occupier and investor portfolios, meaning a lender cannot use one book to dilute the other.
• The ongoing serviceability buffer of 3 percentage points above the actual loan rate, which continues to compress borrowing capacity across all borrower types.
• Rising compliance costs for lenders managing complex borrower structures, including trusts, companies, and self-managed super funds.
• Increased scrutiny from ASIC on responsible lending obligations, pushing lenders to tighten income verification and expense assessment processes.

The result is a lending environment where lender behaviour is already shifting in anticipation of these constraints even where the DTI cap is not yet binding on most borrowers, credit appetite is tightening and approval conditions are becoming more complex. Mortgage brokers who understand this gap and know how to bridge it are the ones writing the most business right now.

The Five Biggest Lender Policy Changes Impacting Applications Right Now

1. Tighter Income Verification Requirements

One of the most consistent changes across lenders in the current environment is the tightening of income verification standards. Lenders are now requiring more documentation, more recent payslips, and in many cases, a longer history of income stability before they will accept an application.

• For brokers, this means:
  • Payslips must typically be dated within 30 days of application submission.
  • Year-to-date income figures are being cross-checked against tax returns more rigorously.
  • Overtime, commission, and bonus income is being assessed more conservatively, with many lenders now requiring a two-year average rather than accepting the most recent figure.
  • Rental income from investment properties is being shaded at a higher rate, with some lenders applying a 70% to 75% acceptance rate rather than the previous 80%.

Broker action: Prepare a complete income documentation pack for every client before submitting. Do not rely on the lender to request missing documents after submission. Delays cost approvals.

2. Trust and Company Lending Restrictions

This is one of the most significant policy shifts affecting property investors and high-net-worth borrowers. Major lenders have either restricted or paused new lending to trusts and companies due to rising compliance risks, the complexity of assessing income and liability within these structures, and a surge in social media content particularly on TikTok instructing borrowers on how to use trust structures to artificially stretch their borrowing capacity.

The impact on brokers is direct, and the limitations are highly lender-specific, as tracked in The Broker Times Trust Lending Framework:

• Macquarie Bank has fully paused new home loan applications where the borrower is a trust or company.
• Commonwealth Bank has restricted broker-introduced applications, requiring non-individual borrowers to have an existing CBA lending facility active for at least six months.
• ANZ has limited trust and company lending to existing customers only, with a maximum LVR of 70%.
• Westpac has also tightened eligibility criteria and reduced maximum LVRs for these borrower types.

Broker action: For clients with trust structures, pivot immediately to non-bank lenders such as Pepper Money, Liberty Financial, and Resimac, who have maintained more flexible policies for trust and company borrowers.

3. Self-Employed Income Assessment Changes

Self-employed borrowers have always faced more scrutiny than PAYG applicants. But the current policy environment has made this gap even wider.

• Lenders are now applying stricter rules around:
  • The number of years of tax returns required, with most lenders now requiring a minimum of two full years of business tax returns and personal tax returns.
  • Add-backs, with lenders becoming more conservative about which business expenses they will add back to calculate true income.
  • Business viability assessments, with some lenders now requiring a letter from an accountant confirming the business is trading profitably and has a positive outlook.

For self-employed borrowers, the difference between a lender who applies generous add-back policies and one who does not can mean a borrowing capacity difference of $100,000 or more on the same income figure.

Broker action: Know which lenders have the most favourable self-employed income policies for your client's specific business structure. This is where broker expertise delivers the most tangible financial value to clients.

4. Revised Expense Assessment and Living Cost Benchmarks

Following increased ASIC scrutiny on responsible lending, lenders have updated how they assess a borrower's living expenses. Most lenders now use the Household Expenditure Measure (HEM) as a minimum benchmark, but many are applying higher figures based on postcode, household size, and declared lifestyle expenses.

• What this means in practice:
  • Borrowers who declare low living expenses are having those figures challenged by lenders who apply HEM benchmarks automatically.
  • Higher declared expenses are reducing net income figures and, therefore, reducing borrowing capacity.
  • Lenders are cross-referencing bank statement expenses against declared figures more rigorously than ever before.

Broker action: Coach clients to review their bank statements before applying. Unnecessary subscriptions, high dining expenses, and irregular large transactions can all negatively impact a lender's expense assessment. A three-month clean-up period before application can meaningfully improve borrowing capacity.

5. Changes to Investment Lending Policies and LVR Limits

Property investors are facing a double impact in the current environment. Not only are DTI caps limiting how much they can borrow relative to income, but several lenders have also tightened their loan-to-value ratio (LVR) policies for investment lending.

• Key changes include:
  • Some lenders have tightened maximum LVRs for investment loans, with certain lenders reducing limits that previously allowed up to 90% confirm current LVR caps directly with each lender on your panel before submitting investor applications.
  • Interest-only periods for investment loans are being assessed more conservatively, with lenders stress-testing the principal and interest repayment from day one.
  • Portfolio lending, where a borrower has multiple investment properties across different lenders, is being assessed with greater scrutiny of total debt exposure.

Broker action: For investor clients, model the application across multiple lenders before submitting. The difference in borrowing capacity between a lender with a 90% LVR policy and one with an 80% LVR policy can be the difference between a deal proceeding or collapsing.

What the Best Brokers Are Doing Differently Right Now

The brokers who are consistently getting approvals in this environment share a common approach. They are not just submitting applications and hoping for the best. They are doing the work before the application goes in.

Here is what separates the top performers:

• They maintain a live lender policy matrix that tracks current income assessment rules, LVR limits, trust lending policies, and DTI appetite across their panel of lenders.
• They pre-qualify clients against multiple lenders before choosing where to submit, reducing the risk of a declined application damaging the client's credit file.
• They communicate policy changes to clients proactively, positioning themselves as the expert guide rather than just the paperwork processor.
• They leverage non-bank lenders strategically for clients who fall outside major bank credit appetite, rather than treating non-bank lenders as a last resort.

The brokers who treat lender policy knowledge as a core professional skill are the ones building the strongest client relationships and the most referral-driven businesses.

Key Takeaways for Mortgage Brokers

• Lender credit policies are changing rapidly across income verification, trust lending, self-employed assessment, expense benchmarking, and LVR limits.
• APRA's DTI cap and the 3% serviceability buffer are the primary regulatory drivers behind the current wave of policy tightening.
• Self-employed borrowers and property investors are the most affected client segments right now.
• Non-bank lenders, including Pepper Money, Liberty Financial, and Resimac, offer viable pathways for clients who fall outside major bank credit appetite.
• Proactive preparation, complete documentation, and lender policy knowledge are the three skills that separate growing broker firms from stagnant ones.
