Your eligibility to refinance depends on four core requirements: sufficient equity in your property, stable income that services the new loan amount, acceptable credit history, and a property valuation that supports the lending ratio.
Most lenders require at least 20% equity to refinance without incurring Lenders Mortgage Insurance, though some will approve applications with lower equity if your employment and income position is strong. For Ambulance Victoria employees on permanent rosters, your base salary plus penalty rates and allowances typically form the basis of serviceability calculations.
How Lenders Assess Your Income as an AV Employee
Lenders assess your income differently depending on your employment classification and roster pattern. Permanent paramedics and control staff with consistent shift patterns can usually claim 100% of their base salary, plus a percentage of their penalty rates and allowances based on a 12-month average.
Consider an Intensive Care Paramedic refinancing to access equity for an investment property. Their base salary is $95,000, but with night shifts, weekend penalties, and overtime averaging $22,000 annually, their total income sits around $117,000. Most lenders will accept 80% to 100% of that penalty income if it appears consistently across payslips and has been earned for at least three months, with some requiring six months of evidence.
Casual or part-time AV staff face tighter assessment. Lenders typically require 12 to 24 months of consistent hours before they'll include that income in serviceability calculations. If you've recently moved from casual to permanent status, the shift in employment type works in your favour even if your total income hasn't changed.
Equity Position and Loan-to-Value Ratio Requirements
Your available equity determines whether you can refinance and what rate you'll access. Equity is the difference between your property's current value and what you owe on the loan.
If your property is valued at $650,000 and your remaining loan balance is $480,000, your equity is $170,000. Most lenders will allow you to borrow up to 80% of the property value without additional insurance costs, which in this scenario means a maximum loan of $520,000. That leaves $40,000 accessible if you want to refinance and withdraw funds, though doing so may affect your interest rate depending on the final lending ratio.
Refinancing when your equity sits below 20% is still possible, particularly for AV employees who can access LMI waivers through certain lenders. These waivers allow you to refinance at higher loan-to-value ratios without paying the insurance premium that would normally apply. If you're coming off a fixed rate period and your property value has increased since you took out the original loan, your equity position may have improved enough to avoid LMI even without a waiver.

Credit History and What Lenders Will Accept
Your credit file needs to show responsible borrowing behaviour. Lenders will review defaults, late payments, and credit enquiries from the past five years, with particular attention to the most recent 12 months.
One or two missed payments on a credit card or utility bill won't automatically disqualify you, but defaults over $500 or multiple missed loan repayments will narrow your lender options. If you have a default listed, some lenders will still approve your refinance application if the default is older than 12 months, paid in full, and your conduct since then has been clear.
Multiple credit enquiries in a short period can also raise questions. If you've applied for several credit cards or personal loans in the past six months, lenders may view that as financial stress. Refinancing enquiries are treated differently, as lenders understand you're comparing options, but applying for new consumer credit while trying to refinance can complicate your application.
Property Valuation and How It Affects Approval
Lenders will order a valuation to confirm your property's current market value. This valuation determines your loan-to-value ratio and whether the amount you want to borrow is supported.
Valuations can come in lower than expected, particularly in areas where recent sales data is limited or property conditions have changed. If you've made improvements to your home, mention them during the application process. Renovations like updated kitchens, additional bathrooms, or extensions can increase your property's assessed value, which directly improves your equity position and may open up access to lower rates.
If the valuation comes in below what you anticipated and your loan-to-value ratio exceeds 80%, you have three options: accept the higher rate that comes with a higher lending ratio, contribute additional funds to reduce the loan amount, or challenge the valuation with supporting evidence if you believe it's incorrect.
Serviceability Buffers and Expense Assessment
Lenders apply a serviceability buffer when assessing whether you can afford the new loan. They don't just check if you can meet repayments at the current interest rate - they test whether you could still afford repayments if rates increased by 3% or more.
Your declared living expenses are also scrutinised. Lenders use either your actual expenses or a benchmark figure based on the Household Expenditure Measure, whichever is higher. If you have dependents, high childcare costs, or private school fees, these will reduce your borrowing capacity. On the other hand, if you're a single AV employee with low fixed expenses and no dependents, your serviceability position is typically strong even at modest income levels.
Existing debts also affect serviceability. If you're carrying personal loans, car loans, or credit card limits, those commitments reduce how much you can borrow. Paying down or consolidating debt before refinancing can improve your serviceability, and in some cases, consolidating debt into your mortgage during the refinance can lower your total monthly commitments and improve cashflow.
Employment Stability and Probation Period Considerations
Most lenders require you to be past any probation period before they'll approve a refinance, though this rule is more flexible than it used to be. If you've recently started with Ambulance Victoria but have a history of employment in the ambulance sector or healthcare, some lenders will accept that continuity.
If you're currently on probation, waiting until you're confirmed as permanent will widen your lender options and may result in a lower rate. The exception is if your fixed rate is expiring and waiting would mean rolling onto a significantly higher variable rate. In that situation, applying with a lender who accepts probationary employees can still save you money compared to staying on your existing loan.
What Happens If You Don't Meet Standard Criteria
Not every refinance application fits standard lending policy. If your income is variable, your credit file has blemishes, or your equity is tight, you may still have options through specialist lenders or by adjusting your loan structure.
Some lenders assess AV income more favourably than others, particularly when it comes to penalty rates and overtime. If one lender declines your application based on serviceability, a different lender with more flexible income assessment may approve the same scenario. Similarly, if you're self-employed as a paramedic contractor or running a side business, lenders who specialise in self-employed income can assess your application using tax returns or accountant-prepared financials rather than payslips.
If your goal is to release equity but your loan-to-value ratio is too high, you can structure the refinance with a smaller withdrawal and revisit the equity release once your loan balance reduces or your property value increases. The key is matching your circumstances to the right lender and loan structure rather than forcing an application through a policy that doesn't suit your situation.

Frequently Asked Questions
How much equity do I need to refinance my home loan?
Most lenders require at least 20% equity to refinance without Lenders Mortgage Insurance. If you have less than 20% equity, you may still refinance using an LMI waiver available to Ambulance Victoria employees through certain lenders.
Will lenders accept my penalty rates and overtime when refinancing?
Yes, most lenders will accept 80% to 100% of your penalty rates and overtime if they appear consistently on your payslips for at least three to six months. Permanent AV employees with regular shift patterns typically have the strongest income assessment.
Can I refinance if I have a default on my credit file?
You can still refinance with a default if it's older than 12 months, paid in full, and your credit conduct since then has been clear. Some lenders are more flexible than others when assessing past credit issues.
What happens if my property valuation comes in lower than expected?
A lower valuation reduces your equity and may increase your loan-to-value ratio. You can accept a higher rate, contribute funds to reduce the loan amount, or challenge the valuation with supporting evidence if you believe it's incorrect.
Do I need to be past my probation period to refinance?
Most lenders prefer you to be past probation, but some will accept applications during probation if you have a history of employment in the ambulance or healthcare sector. Waiting until you're confirmed as permanent will widen your lender options.
