Refinancing documentation is not a checklist to work through once you lodge your application.
The most decisive outcomes happen when you prepare your paperwork before you speak to a lender, not after. Lenders assess your application based on what you can substantiate immediately, and incomplete documentation triggers further requests that slow your settlement timeline and occasionally jeopardise approval when rates or policy change mid-process.
Proof of Income: What Lenders Actually Review
Lenders verify income through payslips, tax returns, and employment contracts, but the detail they examine depends on how you earn. For PAYG employees, lenders typically require your two most recent payslips plus a letter of employment confirming your position, salary, and tenure. If you have received a pay rise or bonus in the past three months, include a payslip that reflects the updated amount rather than an older figure that understates your income.
Self-employed applicants face more scrutiny. Lenders will request two years of tax returns plus two years of financial statements or notice of assessments from the ATO. Consider a business owner in Bundoora looking to refinance to a lower rate after their fixed term expired. Their accountant had lodged the most recent tax return but the notice of assessment had not yet been issued by the ATO. Without that notice, the lender could not verify the declared income, delaying approval by six weeks. Requesting the notice of assessment from your accountant before you apply removes that gap.
Property Valuation and Supporting Documents
Lenders order their own valuation, but you should prepare supporting documents that demonstrate your property's condition and any improvements made since purchase. Renovation receipts, council permits, and recent comparable sales in your suburb strengthen the valuation outcome, particularly if you have renovated or extended the property.
In suburbs with segmented markets such as Bulleen, where the three-bedroom median sits around $1,196,000 but the four-bedroom median reaches $1,372,500, bedroom count and land size materially affect valuation. If you have converted a study into a fourth bedroom or added a second living area, include the council approval and builder's invoice to ensure the valuer captures the configuration accurately.

Liabilities: Existing Loans, Credit Cards, and Buy Now Pay Later
Every liability you hold affects your borrowing capacity, even if the balance is zero. Lenders assess credit card limits, not balances, which means a card with a $20,000 limit reduces your serviceability by the same amount whether you owe $20,000 or nothing. If you hold cards you no longer use, close them before you apply and request a closure letter from the provider. That letter allows the lender to exclude the limit from their serviceability calculation immediately rather than waiting for the account to drop off your credit file.
Buy Now Pay Later accounts such as Afterpay or Zip also appear in serviceability assessments. Lenders typically apply a minimum monthly repayment assumption of three percent of the limit or account balance, whichever is higher. If you have multiple accounts, consolidating or closing them before you lodge improves your serviceability without changing your actual spending.
For those refinancing to release equity for investment purposes, existing investment loan statements become critical. Lenders will review rental income from investment properties and offset that income against the loan repayments, but only if you provide a current lease agreement and evidence of rental payments received. If your tenant pays into a separate account, include three months of bank statements for that account to verify the income stream.
Bank Statements and Living Expense Verification
Lenders assess your spending patterns through three to six months of transaction history on all accounts where your salary is deposited or regular expenses are debited. They apply the Household Expenditure Measure (HEM) benchmark but will adjust that figure upward if your actual spending exceeds the benchmark.
Large one-off transactions attract attention. A $15,000 debit for a family holiday or medical procedure will prompt the lender to ask whether that expense is ongoing. Annotating your statements before submission or preparing a brief explanation for irregular debits saves time during assessment. Gambling transactions, even small amounts, are treated more strictly. Frequent deposits or withdrawals from betting accounts can trigger a decline regardless of the amounts involved.
Identity Documents and Residency Status
You will need a current driver's licence or passport plus a secondary identity document such as a Medicare card, rates notice, or utility bill in your name at your current address. If you have changed your name since your last loan application, include the relevant marriage certificate, deed poll, or divorce order.
For Australian citizens living overseas or temporary residents refinancing in Australia, visa status and income source determine which lenders will assess your application. Expat applicants typically need an offshore employment contract, evidence of the employer's Australian presence or international standing, and confirmation that income will continue throughout the loan term. Some lenders will only accept applications from citizens or permanent residents, narrowing your options if you hold a temporary visa.
How Long Does Refinance Approval Take Once Documents Are Lodged?
Most lenders assess a complete application within five to ten business days, but that timeline assumes all required documents are provided upfront. Each missing item adds at least three to five days to the process as the lender requests the document, you source it, and the file returns to the assessor's queue. For applications lodged during peak periods such as the weeks following a fixed rate expiry wave, processing times extend further.
Settlement typically occurs 30 to 45 days after formal approval, depending on the complexity of your loan structure and whether you are switching lenders or retaining your current lender under a new product. If you are consolidating debt, selling a property, or purchasing an additional asset as part of the refinance, add at least two weeks to that timeline.
Preparing Documentation Reduces the Risk of Rate Movement
Rate locks are not indefinite. Most lenders will hold a rate for 90 days from formal approval, but that protection only applies once your application is approved. If your documentation is incomplete and assessment drags into a second or third round of requests, the rate you were quoted at application may no longer be available by the time you reach formal approval.
In our experience, clients who provide complete documentation at the outset and respond to any lender queries within 24 hours settle at the rate they were originally quoted. Those who defer document collection or provide incomplete records often face a choice between accepting a higher rate or withdrawing and reapplying under revised terms.
