Refinancing Approval: What Lenders Check & How to Prepare

Refinancing a home loan involves the same approval checks as a new mortgage application.

You'll need to prove your income, demonstrate your ability to repay, and satisfy serviceability rules even if you've been making payments on your current loan for years. Many property owners in Kew assume their existing payment history automatically qualifies them for a new loan, but lenders assess your current financial position rather than past performance. Understanding what gets assessed and when to start preparing makes the refinance application move faster and reduces the chance of delays or declines.

How Lenders Assess Your Refinance Application

Lenders evaluate your income, expenses, liabilities, and property value to determine whether you can service the new loan.

Your income gets verified through payslips if you're an employee or tax returns and business financials if you're self-employed. Lenders apply a buffer rate above the actual interest rate when calculating serviceability, typically adding around 3% to the loan rate you're applying for. Your living expenses are assessed either through your actual declared spending or a benchmark figure that lenders use called the Household Expenditure Measure. This benchmark often exceeds what you actually spend, particularly for households without dependents.

Consider a couple in Kew with a $750,000 mortgage who want to refinance to a lower rate. They earn a combined $180,000 and have $800 monthly on a car loan. Even though they've never missed a payment on their existing mortgage, the lender applies the buffer rate to the new loan and calculates their expenses using HEM, which might assess their living costs at $3,200 per month regardless of actual spending. If the numbers don't meet the serviceability threshold, the application gets declined despite their spotless payment record.

Property valuation is the other major factor. Lenders order a desktop valuation or a full inspection to confirm your property's current worth. If your property value has increased since you purchased, you might access a lower loan-to-value ratio and qualify for a reduced rate. If values have declined or remained flat, you might have less equity than expected, which can affect your borrowing capacity or rate eligibility.

What Documents You'll Need to Provide

You'll submit income verification, identification, and property details when you lodge a refinance application.

Employees typically provide their last two payslips and two years of tax returns. If you've recently changed jobs or have a bonus component, expect to provide employment contracts or letters confirming your income structure. Self-employed applicants need two years of tax returns including the full Notice of Assessment, business financials, and often a letter from an accountant confirming income. If your business is structured through a trust or company, you'll need to provide those entity documents as well.

Lenders also ask for statements from all your bank accounts, credit cards, and any loans you hold. They review these statements to confirm your declared income hits your account, to check for any undisclosed liabilities like buy-now-pay-later arrangements, and to verify you don't have patterns of irregular spending or frequent overdrafts. You'll also need to provide council rates for the property you're refinancing and recent statements for your existing home loan showing the current balance and repayment history.

In our experience, missing or outdated documents are the most common reason applications stall. Lenders won't progress an application until they have everything they need, and chasing documents after submission can add weeks to the process.

Timing Your Application Around Fixed Rate Expiry

If your fixed rate period is ending, start the refinance process at least 60 to 90 days before the expiry date.

This timeframe allows enough room to compare options, submit the application, receive approval, and settle the new loan before you roll onto your lender's standard variable rate. Most lenders in Australia can process a straightforward refinancing application within three to four weeks, but complications like missing documents, low valuations, or serviceability concerns can stretch this out.

Many property owners around Kew with period homes or heritage overlays find valuations can take longer if the lender requires a physical inspection rather than a desktop assessment. If you wait until the month your fixed rate expires to start looking, you'll almost certainly end up on the variable rate for at least one or two months while your new loan processes. Depending on the rate difference, that delay could cost you hundreds of dollars in extra interest.

If you're locked into a fixed rate with months or years remaining, you'll face break costs to exit early. These costs depend on the difference between your fixed rate and the current wholesale rate your lender can get for the remaining fixed period. In a rising rate environment, break costs are typically low or zero. In a falling rate environment, they can run into thousands of dollars. A fixed rate expiry review can help you understand whether waiting or moving now makes more financial sense.

Accessing Equity Through Your Refinance

Refinancing can unlock equity in your property for investment, renovations, or debt consolidation.

Lenders typically allow you to borrow up to 80% of your property value without paying lenders mortgage insurance. If your property has increased in value or you've paid down your loan balance, the gap between what you owe and what you can borrow creates usable equity. As an example, if your Kew property is now valued at $1.4 million and you owe $600,000, you could potentially borrow up to $1.12 million, giving you access to $520,000 in equity minus costs.

You can use that equity to fund a deposit on an investment property, complete a renovation, consolidate personal debts into your mortgage, or hold it in an offset account for future use. However, accessing equity increases your loan amount and your monthly repayments, so lenders assess your ability to service the higher borrowing. If your income hasn't increased proportionally, you might not qualify for the full amount of equity available.

Equity release also changes your loan-to-value ratio. Borrowing above 80% typically requires you to pay lenders mortgage insurance, which can add thousands to your upfront costs. Structuring the refinance to stay at or below 80% LVR often delivers lower rates and avoids the insurance premium. Working through your goals and numbers with a mortgage broker before you apply helps you understand what's achievable and what the cost implications are.

Switching Loan Features When You Refinance

Refinancing lets you add or remove features like offset accounts, redraw facilities, or split rate structures.

If your current loan lacks an offset account, refinancing to a product that includes one can reduce the interest you pay without changing your repayment amount. Depositing your savings into an offset account linked to your mortgage reduces the balance on which interest is calculated daily. Over time, this can shave years off your loan term and save substantial interest.

You might also switch from a variable to a fixed interest rate, split your loan between fixed and variable portions, or consolidate multiple debts into a single mortgage facility. Each of these changes affects your repayment structure, so the lender assesses your application based on the new loan terms, not your existing arrangement. Consolidating debts into your mortgage extends the repayment period from a few years to potentially 30 years, which lowers monthly costs but increases total interest paid unless you maintain higher repayments.

Kew's median property value sits well above the Melbourne average, and many homeowners carry mortgages that benefit from flexible features. If cashflow is tight due to school fees at one of the local private schools or other family expenses, an offset account combined with a redraw facility gives you options to manage irregular income or lumpy expenses without refinancing again. A loan health check can identify whether your current loan structure still fits your circumstances or whether switching features would improve your position.

What Happens After You Submit Your Application

Once your application is lodged, the lender orders a valuation and begins credit and income assessments.

The valuer inspects your property or completes a desktop report depending on the loan amount and property type. Credit checks confirm your existing liabilities and repayment history. The lender's credit team reviews your income documents, calculates serviceability, and determines whether you meet their policy criteria. If everything aligns, you receive formal approval and loan documents to sign.

Settlement usually occurs within a few weeks of signing. The new lender pays out your existing mortgage and registers the new loan against your property title. From that point, your repayments switch to the new lender at the new rate and terms. If you're refinancing to access equity, the additional funds are typically released at settlement either directly to you or to a third party such as a seller if you're purchasing another property.

If the application hits a snag, the lender might request additional documentation, ask for explanations around certain transactions, or decline the application outright. Declines usually relate to serviceability issues, undisclosed debts, or insufficient property value. If your application is declined, you can address the concerns and reapply with the same lender, try a different lender with different criteria, or adjust your borrowing amount to meet serviceability thresholds.

Refinancing approval follows the same rigorous process as a new home loan, but understanding what lenders assess and preparing your documents in advance makes the process move faster. Whether you're looking to access a lower rate, release equity, or switch loan features, knowing how the application works and what to expect at each stage puts you in control.
