Mortgage Broker Document Checklist: Validate the File

An Australian mortgage broker needs, for each applicant, photo ID and a second identity document, the two most recent payslips, an ATO income statement or tax return and notice of assessment, three months of bank statements showing genuine savings, and a full account of living expenses and existing debts. The checklist only helps when each item is also checked for completeness, dates and agreement with the rest of the file. That second layer is what stops a lender returning the application after submission.

What documents does a mortgage broker need from a client?

A broker needs identity, income, savings, expense and debt documents, and the income package changes between PAYG employees, self-employed borrowers and contractors. Each lender has its own policy, but the core list is similar across the major banks and non-bank lenders.

Under the National Consumer Credit Protection Act 2009, a credit provider must make reasonable inquiries about the consumer's requirements and financial situation and take reasonable steps to verify it, and brokers owe a best interests duty to the client (National Consumer Credit Protection Act 2009, legislation.gov.au). The documents in the file are the evidence of those inquiries and verifications.

The ATO provides employees with an income statement through myGov, which lenders use to cross-check payslips (ATO). Confirm the specific lender's policy before the client starts gathering.

How do you check that each document is complete?

A document is complete when every page is present and every field the credit assessor needs is legible. Missing pages are the most common cause of a request for further information.

Run these checks on every upload:

1. All pages of each bank statement. A statement that jumps from page 1 of 4 to page 3 of 4 hides transactions the lender will want to see.
2. Complete payslip. Employer name and ABN, employee name, pay period, gross, tax, net and year-to-date figures.
3. Full tax return and notice of assessment. Both are usually needed for self-employed borrowers.
4. Both sides of the driver licence where the lender verifies the card number.
5. Gift or guarantor documents signed and witnessed as the lender requires.

A tick against "tax return received" does not confirm that every schedule arrived. The check is whether the field is on the page.

Which dates and expiry rules cause rejections?

Dates cause rejections because lenders set freshness windows and a file can age out while the broker is still collecting. The application is clean on day one and stale a month later.

• Payslips: the most recent two, generally within 30 to 60 days of submission.
• Bank statements: the latest three months, with genuine savings usually assessed over the same period.
• ID documents: unexpired at submission and at settlement.
• Credit reports: refreshed when the lender runs its own enquiry.
• Contract of sale: the finance clause and the unconditional date set the real deadline.
• Approval validity: conditional approvals expire, often after 90 days, so a delayed purchase needs an extension.

Record a "stale by" date in the file: the oldest document date plus the lender's window. When the file passes it, it goes back to the client before it goes to the lender.

Which cross-document checks do credit assessors run?

Cross-document checks compare the same fact across multiple documents, and a mismatch is what makes an assessor pause. Each document can be correct on its own while the file contradicts itself.

The declared-versus-actual expenses comparison is the one that surprises borrowers most, because lenders benchmark living costs against the Household Expenditure Measure and compare with the transaction history. Our article on cross-document validation beyond OCR explains why reading each document alone misses these comparisons.

A comparison of fields shows the file is consistent. It does not prove any document is genuine and should never be described as doing so.

What is the broker's own compliance load?

Mortgage brokers hold an Australian credit licence or act as credit representatives, regulated by ASIC, and must be members of the Australian Financial Complaints Authority. Brokers arranging loans are also within AUSTRAC's remit under the AML/CTF Act 2006 where they provide designated services, which means identifying customers and reporting suspicious matters to AUSTRAC.

Client personal information falls under the Privacy Act 1988 and the Australian Privacy Principles, and the OAIC handles notifiable data breaches. Where the file is stored and who can open it are compliance questions as well as IT ones.

On the funds side, the file should show where the deposit was, for how long, and who paid it in. Triggers for a closer look include a lump sum in the last month, funds from a third party or overseas, and proceeds from a property sale with no settlement statement.

What do brokers and borrowers ask in forums?

Threads on r/AusFinance and r/AusPropertyChat circle the same questions.

"My lender wants more documents after conditional approval. Why?" Conditional approval often rests on declared figures. Full assessment compares those with documents, so a mismatch invisible earlier appears now. Validating before submission is cheaper than answering requests afterward.

"How old can payslips and statements be?" Two recent payslips and three months of statements are common. Ask the lender and write the window in the file.

"What counts as genuine savings?" Regular deposits built up over three months or more, as opposed to a lump sum, gift or loan arriving shortly before application. Lenders differ, so check the policy.

"I changed jobs a month ago. Will that affect my loan?" Often it changes the paperwork more than the answer: employment contract, first payslips and probation status. The checklist for a recent job change is longer than for a ten-year employee.

A validation routine to run before every submission

Run the same four steps in the same order on every file so the result does not depend on who handles it.

1. Collect against the target lender's list, not a generic one.
2. Check completeness: pages, fields, signatures.
3. Check validity: dates against the lender's windows, ID expiry.
4. Check consistency: names, addresses, employers, income, expenses and savings across the file.

A brokerage submitting dozens of applications each month usually finds the first two steps work by eye and the fourth does not, since comparing six documents manually is the step that gets skipped. Automated extraction and comparison flags only the differences. For firms placing credit files, our financing and leasing solution describes the comparison, the pricing page shows cost per file, and the security page covers data handling. For the wider picture, read the industry verification guide; for the consumer credit equivalent, read income document validation before a credit decision.

Frequently asked questions

What is a mortgage broker document checklist?

It is the list of documents a broker collects before submitting a home loan: ID, income, savings, expenses, debts and property documents. A good checklist also records the freshness window for each item so stale documents are caught early.

What documents do Australian lenders require for a home loan?

Typically photo ID, two recent payslips, an ATO income statement, three months of bank statements, details of living expenses and debts, and the contract of sale. Self-employed borrowers add two years of tax returns and notices of assessment.

How many months of bank statements does a mortgage broker need?

Three months is the usual requirement, and some lenders ask for more where income is variable or savings need evidencing over a longer period.

How can a broker reduce back-and-forth with credit assessors?

Check completeness, date validity and cross-document consistency before submission. Most requests trace to a missing page, an out-of-date payslip or expenses that do not match the transaction history.
