What Lenders Look for When You Refinance
Lenders assess your current income, property value, existing debts, and credit history to determine whether they'll approve your refinance application. The threshold isn't identical to your original home loan, and circumstances that worked five years ago may not meet current lending criteria.
Consider a property owner on the Central Coast who purchased in Terrigal and now wants to refinance to access equity for an investment property. Their household income has stayed consistent at around $140,000, but they've taken on a car loan and increased their credit card limit. Even though they've built substantial equity through price growth and principal repayments, the additional debt affects their borrowing capacity. The lender recalculates what they can afford using current serviceability buffers, which means the amount they can draw depends on proving they can service both the increased mortgage and their other commitments.
Your employment type also plays a role. Someone who was a permanent employee when they first borrowed but is now self-employed will need to provide two years of tax returns and often a notice of assessment before a lender will treat that income as stable. This doesn't make refinancing impossible, but it does mean your documentation requirements change.
Equity Position and Loan-to-Value Ratio
Your loan-to-value ratio is the percentage of your property's current value that you owe. Most lenders allow you to refinance up to 80% LVR without needing lenders mortgage insurance, though some will go higher if you're willing to pay the premium.
Property values across the Central Coast have shifted over recent cycles, and what your home is worth today determines how much equity you can access. A property in Gosford purchased several years ago may have appreciated, but if you're refinancing to consolidate debt or fund renovations, the lender will order a valuation to confirm the current market value. That valuation directly impacts whether you meet the LVR threshold for the loan amount you're requesting.
If you're sitting above 80% LVR after calculating your desired loan amount against the new valuation, you'll either need to reduce what you're borrowing, accept LMI costs, or wait until you've paid down more of the principal. Some lenders offer slightly more flexibility depending on your income strength and credit profile, but the 80% mark remains the clearest line for most applicants.
Income and Serviceability Assessment
Serviceability is the lender's calculation of whether you can afford the loan repayments based on your income and expenses. They apply a buffer rate above the actual interest rate you'll pay, typically adding 3% to the loan rate, and assess whether you can still meet repayments under that scenario.
In a scenario where someone has moved from full-time employment to a combination of part-time work and rental income from a second property, the lender treats those income sources differently. Part-time wages are usually accepted at face value if there's a consistent history, but rental income is often shaded down to 80% of the actual rent received to account for vacancy periods and maintenance costs. This shading reduces the total income figure used in the serviceability calculation, which can limit the loan amount you qualify for.
Lenders also factor in your living expenses using either your actual declared spending or a household expenditure measure, whichever is higher. If you're supporting dependents or have school fees, childcare, or other regular outgoings, those reduce the amount left over for loan repayments in the lender's eyes. For Central Coast residents with families, this can mean the loan amount a lender approves is lower than expected even when equity and LVR aren't constraints.
Credit History and Existing Commitments
Your credit file records every application you've made for credit, how you've managed repayments, and whether you've defaulted on any accounts. Lenders pull this file during the refinance process, and anything that signals financial stress will either delay approval or result in a decline.
A missed payment on a credit card two years ago might not be fatal, but multiple missed payments or a default will require an explanation and supporting evidence that your circumstances have improved. Some lenders are more accommodating than others, which is where working with a broker who understands each lender's risk appetite becomes valuable.
Existing commitments also matter. If you're carrying personal loans, car finance, or buy-now-pay-later arrangements, the lender includes those repayments when calculating serviceability. Even if you plan to consolidate those debts into the refinanced mortgage, the lender assesses your current position first, then recalculates based on the proposed structure. This is why it's often worth paying down small debts or closing unused credit accounts before applying to refinance your home loan.
Documentation You'll Need to Provide
The documents required depend on your employment type and the complexity of your financial situation. Employees typically provide recent payslips, a letter from their employer, and the last two years of tax returns if they have secondary income sources. Self-employed applicants need tax returns, notices of assessment, business financial statements, and sometimes BAS statements depending on the lender's requirements.
If you're accessing equity or increasing your loan amount, the lender will want to know how you intend to use the funds. If it's for renovations, they may ask for quotes or a builder's contract. If it's for an investment property deposit, they'll assess the viability of that purchase as part of the overall application.
Bank statements are now standard across almost all applications. Lenders use these to verify your income, confirm your savings if required, and check your spending patterns. Frequent cash deposits, gambling transactions, or unexplained transfers can trigger questions, so it's worth reviewing your statements before submitting them and being prepared to explain anything that looks unusual.
When Refinancing Becomes More Difficult
Certain situations make refinancing harder to achieve, even when your loan is otherwise performing. If you've recently changed jobs, some lenders require a minimum employment period before they'll accept your application, typically three months for permanent roles and longer for probationary or casual work.
Self-employed applicants who've experienced a drop in income between financial years will find lenders use the lower figure when assessing serviceability. If your most recent tax return shows reduced profit compared to the prior year, the lender assumes that's the ongoing position unless you can demonstrate the drop was temporary.
Property type also affects eligibility. If you own a unit in a high-density development or a property with non-standard construction, some lenders will decline the application outright or apply stricter LVR limits. This is less common across the Central Coast than in metro areas with high-rise stock, but it's still relevant for certain pockets around Gosford or properties with unique features like bushfire risk or no street access.
How a Loan Health Check Identifies Refinancing Opportunities
A loan health check compares your current loan structure against what's available in the market and assesses whether you meet the eligibility criteria to make a change. It's not just about finding a lower rate; it's about confirming your financial position supports the move and identifying any gaps that need addressing before you apply.
For someone whose fixed rate period is ending, this review becomes particularly valuable. You're not locked in, which means you have the option to stay with your current lender or move elsewhere, but that decision depends on whether another lender will accept your application. If your circumstances have changed since you first borrowed, whether that's reduced income, increased debt, or a shift in employment type, the health check surfaces those issues early so you can either adjust your expectations or take steps to improve your position before applying.
This process also considers what you're trying to achieve. If your goal is to reduce repayments, increase cashflow, or release funds for another purpose, the review factors in how lenders will assess that objective and which products align with your eligibility profile.
Structuring Your Application to Meet Lender Requirements
Meeting refinancing eligibility isn't always about waiting for your circumstances to improve. Often it's about structuring the application in a way that fits within a lender's policy.
If you're self-employed and your most recent tax return doesn't reflect your current income because you reinvested profits into the business, some lenders allow you to add back certain deductions like depreciation when calculating serviceability. This approach requires detailed financials and a clear explanation, but it can mean the difference between approval and decline.
Similarly, if you're refinancing to consolidate debt, the timing of when you close those other accounts matters. Paying out the debt before settlement is standard, but some lenders require evidence that accounts have been closed and won't be redrawn. If you're planning to keep a credit card open but reduce the limit, doing that before the application is submitted improves your serviceability position upfront.
For couples with uneven income, some lenders allow you to apply in one name if that person's income alone is sufficient to service the loan. This can be useful if the other party has credit issues or irregular income that complicates the application. The trade-off is that only one person holds the asset and the liability, which has legal and tax implications that need to be considered.
When to Speak to a Broker About Your Eligibility
If your circumstances have changed since you first borrowed, or if you're unsure whether your current financial position meets refinancing criteria, speaking to a broker before applying prevents wasted time and protects your credit file from unnecessary enquiries. Each application leaves a footprint, and multiple declines make future approvals harder.
Refinancing eligibility isn't static. What you qualified for last year might not match what lenders accept now, and what one lender declines another may approve based on different assessment policies. A broker with access to multiple lenders can match your situation to the right panel and structure the application in a way that maximises your chances of approval while still achieving your financial objective.

Frequently Asked Questions
What loan-to-value ratio do I need to refinance without paying lenders mortgage insurance?
Most lenders allow you to refinance up to 80% LVR without LMI. If your loan amount exceeds 80% of your property's current value, you'll typically need to pay LMI or reduce the amount you're borrowing.
How does being self-employed affect my refinancing eligibility?
Self-employed applicants usually need to provide two years of tax returns and notices of assessment. Lenders assess your income based on the lower of the two years unless you can demonstrate why a drop was temporary.
Will my credit card limit affect how much I can borrow when refinancing?
Yes, lenders include your credit card limit in their serviceability assessment, even if the balance is zero. Reducing or closing unused credit accounts before applying can improve the loan amount you qualify for.
What happens if my property valuation comes in lower than expected?
A lower valuation increases your loan-to-value ratio, which may push you above 80% LVR or reduce the equity you can access. You may need to reduce your loan amount, pay LMI, or wait until you've paid down more principal.
How long do I need to be in a new job before I can refinance?
Most lenders require at least three months in a permanent role before they'll accept your application. Probationary or casual employment may require a longer history or additional documentation.
