Beginner's Guide to Refinancing Documentation

What Documentation You'll Need for a Refinance Application

You'll need to prove income, confirm your property value, and show your current loan position. For self-employed borrowers, that typically means two years of tax returns with Notice of Assessments, business financials, and year-to-date profit and loss statements. Your broker submits these alongside bank statements, ID documents, and a property valuation arranged by the new lender.

The documentation process determines how quickly your refinance home loan application moves through assessment. If you're switching lenders because your fixed rate period is ending, having everything ready before expiry saves you from reverting to a higher variable rate while the application processes.

Consider a plumber running a sole trader operation who decided to refinance when rates started dropping. His current lender held a loan at 6.2%, but he'd found a variable rate at 5.8% with an offset account. He gathered his tax returns, business bank statements, and a recent BAS, then submitted the application six weeks before his fixed term ended. The new lender ordered a valuation that came back within range, and settlement occurred two weeks after his fixed period expired. He spent a fortnight on the revert rate but locked in the lower ongoing rate without disruption.

Income Verification for Self-Employed Borrowers

Lenders assess your last two financial years through tax returns and Notice of Assessments from the ATO. They add back depreciation and other non-cash deductions to calculate your serviceability income, which is often higher than your taxable income. If you've recently expanded or changed your business structure, some lenders will accept a year-to-date profit and loss statement prepared by your accountant to reflect current earnings.

For borrowers operating through a company or trust, you'll also provide company tax returns, financial statements showing retained earnings, and sometimes a letter from your accountant confirming ongoing income capacity. Lenders want to see consistency or growth across the two-year period, though a single down year won't disqualify you if the overall trend supports serviceability.

When you're self-employed, your income documentation takes longer to prepare than wage earners who just provide payslips. Factor in the time needed to collect statements from your accountant, especially during tax season when they're managing other client deadlines.

Property Valuation and Current Loan Details

The new lender arranges a property valuation to confirm your equity position. You don't pay for this upfront in most cases, though it may be added to your settlement costs or absorbed by the lender depending on the deal structure. If the valuation falls short of what you expected, your loan-to-value ratio shifts, which can affect your interest rate or require you to pay lender's mortgage insurance.

You'll also need a payout figure from your current lender showing your remaining loan balance, any break costs if you're exiting a fixed rate early, and discharge fees. This document is valid for a set period, usually 30 days, so request it once your application is close to approval rather than at the start of the process.

In South Australia, property settlements move through PEXA, and your broker coordinates the discharge of your old loan and registration of the new one on the same day. You won't need to attend in person, but you do need to ensure all supporting documents are signed and returned before the scheduled settlement date.

Bank Statements and Transaction Conduct

Lenders review three to six months of bank statements for your personal and business accounts. They're checking two things: that your income deposits match what you've declared, and that your spending patterns don't indicate undisclosed liabilities or financial stress.

For self-employed borrowers, this means your business account activity gets scrutinised alongside your personal statements. Regular cash deposits without clear explanations can raise questions. So can frequent overdrafts, dishonours, or large unexplained transfers. If you're paying business expenses through your personal account or vice versa, that's fine, but be prepared to explain the pattern.

If you run expenses through a business credit card that carries a balance, that liability will be factored into your serviceability even if it's paid off monthly. Lenders apply a repayment buffer based on the card's limit, not your actual usage, so closing unused cards before applying can improve your borrowing capacity.

Documents That Speed Up Assessment

Your broker should request a rates notice, insurance certificate, and body corporate statement if you're refinancing a unit or townhouse. These confirm your ongoing property expenses and let the lender calculate total holding costs accurately. If you're accessing equity for investment or another purpose, you'll also provide a letter of explanation outlining how the funds will be used.

Anything missing from your initial submission delays the application while the lender requests it. A complete file lodged upfront moves through credit assessment faster than one that requires multiple follow-ups. After 16 years of preparing these applications, the difference between a four-week approval and an eight-week approval usually comes down to whether the income documents were complete and current when the file landed on the assessor's desk.

For borrowers with more complex structures, such as multiple income sources across a company, trust, and personal capacity, your accountant becomes part of the documentation process. A well-prepared accountant's letter summarising your income position and confirming ongoing capacity can address questions before the lender raises them.

When You're Consolidating Other Debts

If you're refinancing to consolidate personal loans, car finance, or business debts into your mortgage, you'll need payout figures for each liability. Lenders want to see that the funds released at settlement will fully discharge those debts, not just reduce them. You'll also sign a statutory declaration confirming that the debts will be cleared and won't be redrawn after settlement.

Consolidation makes sense when the interest you're paying on short-term debts exceeds what you'll pay on the mortgage, and when your cashflow improves enough to justify extending the repayment term. It doesn't make sense if you're just shifting repayments around without addressing the underlying spending pattern that created the debt.

Your broker should model the before and after position so you can see the monthly cashflow change and the total interest cost over the life of the loan. That analysis lives outside the documentation checklist, but it determines whether refinancing to consolidate actually improves your position or just defers the problem.

Preparing Your File Before You Apply

Start gathering documents as soon as you decide to refinance. Request your tax returns and Notice of Assessments from your accountant or the ATO portal. Download bank statements covering the last six months for every account linked to your income or expenses. Confirm your loan balance and check whether your current lender will charge break costs or discharge fees.

If your circumstances have changed since you took out your current loan, such as a business structure change, marriage, or additional income sources, flag that with your broker early. It might require extra documentation, but it's easier to address upfront than mid-assessment when the lender requests clarification.

Once your broker has reviewed your documents and confirmed they meet lender requirements, the application can be lodged. A loan health check at that stage also confirms you're moving to a loan structure that suits your current circumstances, not just chasing a lower rate without considering offset access, redraw flexibility, or repayment options.
