Refinancing your mortgage requires you to meet lending criteria that may differ from when you first purchased your property.
Lenders assess your current financial position, not the one you had when you originally borrowed. This means your income, expenses, credit history, and property value all come under review again. The outcome depends on whether your situation demonstrates the capacity to service the new loan and whether the property provides sufficient security.
What Lenders Assess During a Refinance Application
Lenders examine your income stability, current debts, living expenses, and credit file to determine serviceability. They also arrange a property valuation to confirm your equity position. The application process mirrors a new home loan in many respects, though some lenders may streamline certain steps if you're refinancing with your existing provider.
Consider a homeowner in the Central Coast region who refinanced after their fixed rate period ended. Their income had increased since the original purchase, but they'd also added a car loan and increased their credit card limit. The lender assessed their current monthly commitments against verified income to calculate serviceability. The property valuation came in slightly below their expectation due to localised market softening, which reduced the available equity. Even with these factors, the application proceeded because their loan-to-value ratio remained below 80% and their expenses were well-documented.
Income Verification and Employment Stability
You'll need to provide recent payslips, tax returns, or financial statements depending on your employment type. Lenders typically require two years of financials for self-employed applicants and up to three months of payslips for PAYG employees. Employment stability matters, particularly if you've changed roles or industries since your original loan.
In situations where income has reduced or become variable, lenders may assess your capacity more conservatively. A home loan health check before you formally apply can help identify any gaps in your documentation or areas where your application might face scrutiny.
How Your Credit File Affects Refinancing
Your credit history influences both approval and pricing. Lenders review your repayment conduct across all credit accounts, not just your mortgage. Late payments, defaults, or credit enquiries from multiple lenders in a short period can affect your application.
If you've maintained a clean repayment record and your credit score has improved since your original purchase, you may access more favourable pricing. Conversely, any adverse events since your initial loan could limit your options or result in a higher rate being offered.
Property Valuation and Equity Position
Lenders require a current valuation to confirm your property's worth and calculate your loan-to-value ratio. If your property has increased in value and you've reduced your loan balance, you'll have more equity available. If values have declined or remained flat, your LVR may be higher than anticipated.
An LVR above 80% typically triggers lenders mortgage insurance, which adds cost to your refinance. In some cases, if your equity position has deteriorated significantly, you may not meet the lender's risk criteria. This is particularly relevant in areas where property values have softened or if you purchased near a market peak.
Existing Debts and Monthly Commitments
Lenders assess your total debt position, including credit cards, personal loans, car finance, and any investment property loans. They apply serviceability buffers and calculate your expenses using either your declared figures or a benchmark household expenditure measure, whichever is higher.
If you're refinancing to consolidate debts into your mortgage, the lender will assess whether the new loan amount is serviceable based on your income. Reducing or closing unused credit facilities before applying can improve your serviceability outcome.
Self-Employed and Non-Standard Income Applicants
Self-employed borrowers face additional documentation requirements. Lenders typically require two years of tax returns and financial statements prepared by an accountant. If your income has fluctuated or decreased in recent years, this can affect your borrowing capacity.
Some lenders offer low-doc or alternative income verification options, though these usually come with higher rates and lower maximum LVRs. If your business structure has changed or you've recently started a new venture, expect additional questions about income stability.
Timing Your Application After a Fixed Rate Expiry
If you're coming off a fixed rate, your lender will typically roll you onto their standard variable rate unless you take action. Refinancing before your fixed term ends may trigger break costs, which can outweigh the benefit of moving to a lower rate.
Timing matters. Submitting your refinance application four to six weeks before your fixed term ends gives you time to settle the new loan without incurring penalties. Your current lender may also offer a retention rate if you express an intention to refinance elsewhere, though these offers vary and should be compared against the broader market.
When Refinancing May Not Proceed
Applications can be declined or require adjustments if your serviceability has deteriorated, your credit file shows adverse events, or your property valuation falls short. In some cases, the outcome isn't a decline but an approval at a lower loan amount or higher rate than expected.
If your application doesn't proceed as anticipated, working with a mortgage broker gives you access to multiple lenders with different assessment policies. Some lenders apply more generous expense benchmarks, others accept alternative income documentation, and a few specialise in scenarios where mainstream lenders decline.
Preparing your refinance application with a clear understanding of what lenders assess allows you to address potential issues before they delay or derail the process. Gather your documentation early, review your credit file, and have a realistic expectation of your property's current value.

Frequently Asked Questions
What documents do I need to refinance my home loan?
You'll need recent payslips or tax returns depending on your employment type, usually two years of financials for self-employed applicants and up to three months of payslips for PAYG employees. Lenders also require identification, details of your current mortgage, and information about other debts and living expenses.
Can I refinance if my income has decreased since I bought my property?
You may still be able to refinance if your income has reduced, but lenders will assess your current serviceability based on your present circumstances. Some lenders apply more generous assessment criteria than others, so working with a broker can help you find suitable options.
How does my credit history affect my refinancing application?
Lenders review your repayment conduct across all credit accounts, and any late payments or defaults can affect both approval and the rate you're offered. A clean repayment record and improved credit score since your original purchase may help you access more favourable pricing.
What happens if my property valuation comes in lower than expected?
A lower valuation increases your loan-to-value ratio, which may trigger lenders mortgage insurance if you exceed 80% LVR or limit the amount you can borrow. In some cases, you may need to reduce your loan amount or accept different loan terms.
When should I apply to refinance if my fixed rate is ending soon?
Submitting your application four to six weeks before your fixed term expires gives you time to settle the new loan without incurring break costs. Refinancing before your fixed term ends may result in penalties that outweigh the benefit of accessing a lower rate.
