Refinancing gets rejected most often because of missing or outdated paperwork, not because of your loan amount or property value.
Lenders want proof you can service the new loan, and that means providing current income evidence, asset details, and liability statements that match what you've declared. If you're refinancing on the Gold Coast to drop your rate or release equity, knowing exactly what documentation you need before you start will cut weeks off the process and stop your application stalling halfway through.
What Documentation Do You Need to Refinance a Home Loan?
You need current proof of income, recent bank statements, identification, and details of your existing home loan and any other debts. Lenders also require a property valuation, but they typically order that themselves once your refinance application is lodged.
Income evidence is the part most people get wrong. If you're a PAYG employee, you'll need your two most recent payslips and your latest tax return or notice of assessment. If you're self-employed, lenders want two years of tax returns, two years of financial statements, and a letter from your accountant confirming your income. Showing a lender 18-month-old tax returns when they ask for the most recent ones will stop your application cold.
For bank statements, lenders typically want three months of your main transaction account and any offset or savings accounts. They're checking living expenses, not just income. A $120,000 salary means nothing if your spending shows you can't service a lower rate loan. In our experience, applications on the Gold Coast get held up most often because clients provide statements with missing pages or screenshots instead of official PDFs from their bank.
Your current home loan statement should be no older than 30 days and show your loan balance, interest rate, and repayment amount. If you have an offset account or redraw facility, include statements for those as well. If you're refinancing to consolidate other debts into your mortgage, provide statements for credit cards, personal loans, or car loans showing current balances and minimum repayments.
Identification is standard: driver's licence or passport, plus a Medicare card or rates notice to confirm your address. If you've moved recently or your ID shows a different address to the property you're refinancing, you'll need an extra document like a utility bill to connect the two.
Why Self-Employed Borrowers Face Extra Scrutiny
Self-employed applicants need to provide financials that prove consistent, sustainable income over at least two years. Lenders treat self-employed income differently because it fluctuates, and they want to see you've maintained serviceability across a full business cycle.
Consider a borrower running a trades business in Southport who's been operating for three years. Their tax returns show $95,000 in the first year, $140,000 in the second, and $110,000 in the third. The lender won't average those figures. They'll either take the most recent year or apply a more conservative calculation, depending on their policy. If that borrower applies to refinance to a lower rate without updated financials, the lender may assess them on the lowest income year, which could mean a declined application or a lower approved loan amount than expected.
Financials must be prepared by a registered accountant, and some lenders require a specific declaration from that accountant confirming the figures. If your accountant is on leave or your financials are six months old, you'll need to get updated statements prepared before lodging. Waiting until the lender asks for them after submission adds two to three weeks to your timeline.

How Existing Liabilities Affect Your Refinance Application
Every liability you carry reduces how much you can borrow, even if you're refinancing an existing loan. Lenders assess your borrowing capacity based on your current debts, so if you've taken out a car loan or increased your credit card limit since you first bought the property, that affects what loan amount you can now support.
In a scenario like this: a client refinancing a property in Robina has a $450,000 mortgage, a $25,000 car loan, and two credit cards with a combined limit of $30,000. Even if they only owe $2,000 on the cards, the lender assesses them as if they're fully drawn. That $30,000 in available credit reduces their serviceability by around $3,000 per year in assessed repayments, which can be the difference between approval and decline if their income is tight.
If you're refinancing to access equity or consolidate debt, provide liability statements that show exactly what you owe and what the repayments are. If you've paid out a loan since you last refinanced, provide a statement showing a zero balance or a payout confirmation letter. Lenders won't take your word for it.
Closing unused credit cards before you apply will improve your serviceability and make your application cleaner. If you're not using a card, cancel it and get written confirmation from the provider. That one step can unlock thousands in additional borrowing capacity without changing your income.
What Happens If Your Property Valuation Comes In Low?
The lender orders a valuation once your documentation is approved, and if it comes in lower than expected, your loan-to-value ratio shifts. That can mean you no longer meet the lender's criteria for the loan amount you've applied for, or you may need to pay lender's mortgage insurance where you didn't before.
Property values across the Gold Coast have moved significantly in recent years, but not every property has kept pace. A unit in Surfers Paradise may have strong land value but limited upside compared to a house in Burleigh, and a lender's valuer may take a more conservative view than your last council rates notice or an online estimate.
If you're refinancing to release equity, the valuation determines how much you can access. A $50,000 difference in valuation can mean the difference between getting the funds you need and having to rework your plans. We regularly see this with clients refinancing to fund renovations or access equity for investment. If the valuation comes in below what you expected and the loan amount you need is now above 80% of the property value, some lenders will still approve it but charge a higher rate or require mortgage insurance.
You can't control the valuation, but you can make sure the valuer has access to the property and any recent improvements are visible. If you've renovated the kitchen or added a deck, make sure those details are noted in your application and that the valuer can see them during inspection. A locked gate or an unavailable tenant can result in a desktop valuation instead of a physical inspection, and that almost always comes in lower.
The Difference Between a Refinance and a Loan Health Check
A loan health check is a review of your current loan structure, rate, and features to identify whether refinancing makes sense. It's not an application. It's the step before you start gathering documentation.
If your fixed rate is ending soon, a health check will show you what variable rates are available now and whether switching lenders will save you enough to justify the effort. If you're already on a variable rate but haven't reviewed your loan in three years, a health check will show you how much you're overpaying compared to current market rates.
Running a health check before you pull together all your paperwork saves time. If the numbers don't stack up or your current lender can offer you a comparable rate without the cost of refinancing, you'll know before you've spent hours digging out payslips and tax returns.
How Long Does a Refinance Application Take Once Documentation Is Submitted?
Most lenders take between two and four weeks to assess a refinance application once all supporting documents are provided. That timeline assumes your documentation is complete, current, and matches what you've declared in the application.
If the lender comes back asking for additional statements, updated payslips, or clarification on a transaction in your bank account, that adds another week minimum. If you're self-employed and they query your financials, it can add two to three weeks while you go back to your accountant.
The fastest applications are the ones where every piece of documentation is provided upfront, clearly labelled, and dated within the last 30 to 90 days depending on the document type. Lenders don't process incomplete applications. They park them and move on to the next one. If you're refinancing because your fixed rate period is ending and you need the new loan to settle before your rate reverts, timing matters. Submitting a complete application from the start is the only way to control that timeline.

Frequently Asked Questions
What documents do I need to refinance my home loan?
You need current proof of income such as payslips or tax returns, three months of bank statements, identification, and statements for your existing home loan and any other debts. Self-employed borrowers also need two years of financials prepared by an accountant.
How long does a refinance application take to process?
Most lenders take two to four weeks once all documentation is submitted. Incomplete or outdated paperwork can add one to three weeks to the timeline, especially if you need to provide updated financials or clarify transactions.
Do I need to close my credit cards before refinancing?
Closing unused credit cards improves your borrowing capacity because lenders assess the full credit limit as if it's drawn, even if the balance is zero. Cancelling cards you don't use can unlock thousands in additional serviceability.
What happens if my property valuation comes in lower than expected?
A lower valuation increases your loan-to-value ratio, which may affect your approval or require you to pay lender's mortgage insurance. If you're refinancing to access equity, a low valuation reduces how much you can release.
Why do self-employed borrowers need more documentation to refinance?
Lenders treat self-employed income as higher risk because it fluctuates. They require two years of tax returns and financials prepared by an accountant to prove consistent, sustainable income across a full business cycle.
