About the Author: ODIN Mortgage is a mortgage brokerage exclusively for Australian expats and foreign investors, with 2,300+ clients served across 40+ countries. Mortgage Director Steven Lee brings over 10 years of specialist experience in non-resident lending, giving ODIN Mortgage direct insight into how lender file requirements differ across Australia’s major bank and non-bank lending markets.

Why Does Lender Type Change How a Broker Prepares a File?

The lender type sets the rules of the game before a single document is gathered. Major banks – the big four and their subsidiaries – operate under centralised credit assessment teams with rigid income verification policies and conservative foreign income shading applied uniformly across the portfolio. Non-bank lenders, by contrast, tend to use more flexible credit models and often assess files through relationship-based channels such as specialist BDMs (business development managers), which creates genuine room for brokers to present context and nuance that a bank’s automated system would simply ignore.

This structural difference means the order of documents, the framing of income, and even the labelling of employment contracts must be adapted to the audience. A senior finance professional in Singapore earning in SGD is not a problem for either lender type – but the way that income is evidenced and presented will look materially different depending on where the file is going.

How Do Major Banks Assess Foreign Income on an Australian Expat Home Loan?

Major banks apply formalised income shading policies that reduce the assessable portion of foreign income before calculating borrowing power. The shading is not a penalty – it is a hedge against currency volatility and overseas employment risk. But the rate of shading, and which currencies attract higher discounts, varies significantly from bank to bank, and this information is not published publicly.

For a file targeting a major bank, an experienced broker will typically:

• Source payslips, employment contracts, and bank statements that match the bank’s specific format requirements – some require documents in English or with certified translations.
• Calculate borrowing power using the bank’s known shading rate for the borrower’s currency, so the file is not rejected at assessment because the income figure doesn’t reconcile.
• Provide a clear trail between overseas salary accounts and the Australian deposit funds, since major bank credit teams flag unexplained transfer histories.
• Structure the application to show Australian credit history, even if the applicant has been overseas for several years, since major banks weight local credit behaviour more heavily.

Major banks also tend to require more complete files upfront. A partially packaged application does not go into a queue – it stalls until the outstanding items are resolved, which is where expat timelines often blow out.

How Do Non-Bank Lenders Differ in Their File Requirements?

Building on the major bank framework above, non-bank lenders introduce a different set of variables that require a different packaging approach entirely. Non-banks typically accept a broader range of income evidence – including contractor income, foreign company director income, and offshore self-employment – that major banks will not assess at all.

A file sent to a non-bank lender should lean into the broker’s ability to explain the income structure. Non-bank credit teams are more receptive to a well-written cover note that contextualises an unusual income arrangement – something a major bank’s centralised system simply cannot process.

What Specific Packaging Mistakes Slow Down Expat Approvals?

Stepping back from the structural differences, the practical damage is done at the document level. Research and broker experience consistently identify the same categories of error:

• Using the wrong income figure: Submitting gross income without applying the lender’s known shading rate means the credit team recalculates – and the borrowing power drops. The file then needs to be restructured, adding days or weeks.
• Missing or non-compliant foreign documents: A payslip that meets one lender’s standards may be rejected by another if it lacks required fields (employer address, currency, employment type).
• Unexplained deposit sources: Major banks flag overseas transfers with no paper trail. Non-banks are more tolerant but still need a coherent narrative.
• No foreign income shading reconciliation: Failing to show the lender exactly how assessable income was calculated forces the credit team to do it themselves – introducing errors and delays.

Why Does the Packaging Decision Affect Speed More Than the Lender’s Own Processing Time?

A related but distinct question is whether the lender’s internal speed is the real variable. It is not, in most cases. A well-packaged file at a major bank will typically move faster than a poorly packaged file at a non-bank with a reputation for quick turnarounds. The bottleneck is almost always the number of back-and-forth requests generated after lodgement, not the lender’s baseline processing capacity.

ODIN Mortgage holds lender-by-lender data on how 40+ Australian lenders treat foreign income – including which currencies they accept, how they shade income, and what documentation each lender requires. This data, built from over a decade of non-resident deal flow, is not published anywhere. This preparation helps prevent the round-trip requests that turn a four-week approval into a three-month ordeal.

Frequently Asked Questions

Can an Australian expat apply directly to a bank without using a broker?

Yes, but most major banks have limited capacity to assess complex foreign income situations through their retail channels. Brokers with specialist expat experience hold lender-specific knowledge – including unpublished income shading policies – that materially affects approval outcomes.

Do non-bank lenders charge more than major banks for expat borrowers?

Pricing depends on individual borrower profiles, loan size, and lender policy, which changes over time. The choice between bank and non-bank should be made on the basis of eligibility and file fit, not rate assumptions alone. General information only – this is not personal credit advice.

How is foreign income assessed for an Australian expat home loan in the 2024-25 financial year?

Each lender applies its own income shading policy to foreign-currency earnings before calculating borrowing power. The acceptable shading rate varies by lender and currency. Assessable income and borrowing power depend on individual circumstances and lender policy.

What documents do Australian expats typically need for a loan application?

Common requirements include recent payslips, employment contracts, foreign bank statements, Australian tax returns (if applicable), passport, and evidence of deposit funds. Document format standards vary significantly between lenders.

Is it harder to get approval from a major bank than a non-bank lender as an expat?

Not necessarily harder – but different. Major banks suit PAYG expats with straightforward income and strong Australian credit history. Non-banks often suit more complex profiles. The right lender depends on the individual borrower’s circumstances, not a universal ranking.

Does ODIN Mortgage work with both major banks and non-bank lenders?

Yes. ODIN Mortgage has access to a panel of 40+ Australian lenders accepting foreign income, spanning major banks, regional banks, and non-bank lenders. Lender selection is based on the borrower’s profile and which lender’s criteria best fit the file.

What is income shading and why does it matter for expats?

Income shading is the practice of reducing assessable foreign income by a set percentage before calculating borrowing power. It reflects currency risk and overseas employment uncertainty. The shading rate differs by lender and currency, making broker knowledge of these rates critical to structuring a competitive application.
