Most people assume refinancing is easier than getting their original home loan, then get surprised when a lender asks for the same level of detail all over again.
Lenders treat a refinance application like a new loan, which means you need to meet their current lending criteria even if your circumstances haven't changed. The income test you passed three years ago might not be the same one applied today, and the valuation that got you over the line back then doesn't carry forward. Understanding what lenders actually assess gives you time to fix any gaps before you apply.
What lenders check when you apply to refinance
Lenders assess three main areas: your income and employment stability, your current debts and spending patterns, and the property value relative to how much you want to borrow.
Your income needs to support the new loan at current rates, even if you're borrowing less than you do now. Lenders apply a buffer of around 3% above the actual rate to make sure you can still afford repayments if rates rise. Employment type matters too. If you've recently moved from full-time work to contract or self-employment, some lenders want to see at least six to twelve months of consistent income in that new structure. In our experience, this catches people who assume their total income is all that counts, when lenders are really looking at how reliable that income stream is over time.
Your debts get recalculated from scratch. Credit card limits count as potential debt, even if you pay them off in full each month. A $10,000 limit might reduce your borrowing capacity by $30,000 or more, depending on the lender's assessment rate. Buy now, pay later accounts also get factored in now, particularly if you're carrying multiple active accounts. Lenders pull a fresh credit report, so any missed payments or credit enquiries from the past few months will show up.
Property valuation is the third pillar. Lenders order a new valuation or use an automated model based on recent sales in your area. If your property has dropped in value or hasn't kept pace with what you owe, you might not have enough equity to refinance to a lower rate without paying lender's mortgage insurance again.
How Toowoomba property values affect your equity position
Toowoomba's property market has seen uneven growth depending on the suburb and property type, which directly affects how much equity you can access.
Ranges and north-side suburbs near the escarpment have generally held value over the past few years, while some outer pockets saw slower growth or remained flat. If you bought in an area that's had modest capital growth and you've been on an interest-only loan or making minimum repayments, your equity position might not have shifted much. Lenders typically want you to retain at least 20% equity after refinancing to avoid mortgage insurance, which means if your property is worth $500,000, you'd need to keep your loan under $400,000.
Consider a homeowner in Rangeville who bought for $480,000 a few years back with a 10% deposit. They now owe $420,000 and want to refinance. If the property has appreciated to $520,000, they're sitting on about 19% equity, just shy of the 20% threshold. They could still refinance, but they'd either need to pay lender's mortgage insurance on the new loan or wait until they've paid down a bit more principal. That calculation changes if the valuation comes in at $500,000 instead, which tightens their options further.
If you're looking to access equity for renovations or an investment property, the same equity rules apply but with an added layer. Lenders treat equity drawdowns differently depending on what you're using the funds for. Using equity to buy another property usually gets assessed under investment lending criteria, which can be stricter than owner-occupied refinancing.

Why your income assessment might differ from your first loan
Lending policies shift over time, and the way your income gets assessed now might not match what happened when you first borrowed.
If you're self-employed or running a business in Toowoomba, lenders generally want two years of tax returns and often average your income across that period. If your most recent year shows a dip compared to the previous one, even if it's still solid, that average pulls down your borrowing capacity. Some lenders also add back certain deductions like depreciation, while others don't, so the same tax return can produce different serviceability outcomes depending on who's assessing it.
Payg income is more straightforward, but lenders still vary in how they treat overtime, bonuses, and allowances. One lender might accept 100% of your overtime if you've been receiving it consistently for six months, while another might only count 80% or require twelve months of history. If a chunk of your income comes from shift allowances or commission, it's worth knowing which lenders are more flexible with those income types before you lodge an application.
Rental income from an investment property gets shaded too, usually between 70% and 80% of the actual rent to account for vacancy and maintenance costs. If you're refinancing and own a rental in town, that shading reduces how much assessable income you can claim, which in turn affects how much you can borrow.
What a loan health check reveals before you apply
Running a loan health check a few months before your fixed rate period ends gives you time to address anything that might hold up a refinance.
A health check looks at your current rate compared to what's available now, your loan features like offset or redraw, and whether your borrowing capacity has changed since you first borrowed. It also picks up smaller issues that can delay approval, like credit card limits you no longer use, or outdated contact details with your current lender that slow down the discharge process.
We regularly see people who've been on the same loan for five or more years and have no idea they're paying 1.5% to 2% above current variable rates. That difference on a $400,000 loan can add up to several thousand dollars a year in unnecessary interest. A health check also flags whether you'd benefit from switching loan structures, such as moving from interest-only back to principal and interest, or splitting between variable and fixed.
If the health check shows your equity has grown and your income still supports the loan comfortably, refinancing becomes a straightforward process. If it reveals gaps, such as too many credit enquiries in the past three months or a serviceability shortfall, you've got time to adjust before committing to a formal application.
Documents lenders want and how to prepare them
Lenders ask for recent payslips, bank statements, tax returns if you're self-employed, and proof of identity.
Payslips need to cover the most recent month or two, and they need to match what's hitting your bank account. If your payslip shows $6,000 but your account only shows $5,200 after super and deductions, the lender uses the net figure for serviceability. Bank statements go back three to six months and get reviewed line by line. Lenders look for regular income, any undisclosed debts showing up as recurring payments, and spending patterns that might affect serviceability. Large cash deposits without explanation can also trigger questions, particularly if they coincide with the timing of your application.
If you're self-employed, two years of full tax returns including the notice of assessment are standard. Some lenders also want your accountant to provide a letter confirming your income or a profit and loss statement for the current financial year if your last return is more than a few months old. This can be tricky if you're applying mid-year and your most recent return doesn't reflect a strong year.
Getting these documents together before you start the application process means you're not scrambling when the lender asks, and it also gives you a chance to review your statements for anything that might raise a flag. If you've got a handful of Afterpay transactions or a pattern of spending that pushes close to your income each month, some lenders will factor that into their assessment of your spending behaviour.
When refinancing makes sense and when it doesn't
Refinancing works when the rate or feature improvement offsets the cost and effort involved.
If you're currently paying 5.8% and you can move to 5.3%, the interest saving over a year on a $350,000 loan is meaningful, particularly if you're planning to stay in the property and keep the loan for several more years. Adding an offset account when you don't currently have one can also improve cashflow, especially if you're holding savings in a separate account earning less than the loan is costing you.
Refinancing doesn't always make sense if you're planning to sell within the next twelve months, or if your loan balance is small enough that the absolute dollar saving doesn't justify the time and paperwork. Discharge fees from your current lender, application fees on the new loan, and valuation costs add up, usually somewhere between $500 and $1,500 depending on the lender. If the saving only pays that back after two years and you're moving house before then, you're better off staying put.
It also doesn't make sense to refinance just to pull out equity for discretionary spending that doesn't generate income or improve the property. Using equity to consolidate high-interest debts like credit cards can work if it genuinely reduces your monthly commitments and you close those cards afterwards, but if the cards stay open and get used again, you've just shifted the debt without solving the underlying issue.

Frequently Asked Questions
What do lenders assess when I apply to refinance?
Lenders assess your current income and employment, all existing debts including credit cards and buy now pay later accounts, and the value of your property relative to how much you want to borrow. They treat refinancing like a new loan application, so you need to meet their current lending criteria even if your situation hasn't changed.
How much equity do I need to refinance without paying mortgage insurance?
You typically need to retain at least 20% equity in your property after refinancing to avoid lender's mortgage insurance. If your property is valued at $500,000, your loan would need to stay under $400,000 to meet this threshold.
Why does my income get assessed differently than when I first borrowed?
Lending policies change over time, and lenders apply current serviceability buffers and income shading rules. Self-employed income gets averaged over two years, and overtime or bonus income might be shaded or require longer history than it did when you first applied.
What documents do I need to prepare for a refinance application?
You'll need recent payslips covering one to two months, bank statements going back three to six months, tax returns and notices of assessment if you're self-employed, and proof of identity. Lenders review these in detail to confirm your income and spending patterns.
When does refinancing not make sense?
Refinancing usually doesn't make sense if you're planning to sell within twelve months, your loan balance is too small for the saving to justify the costs, or you're only refinancing to access equity for discretionary spending. Discharge and application fees typically range from $500 to $1,500, so the interest saving needs to cover that within a reasonable timeframe.
