Avoid These 7 Mistakes During Your Refinance Process

The refinancing process typically takes three to five weeks from application to settlement, and most delays or unfavourable outcomes come from avoidable mistakes made in the first few days. Understanding where borrowers commonly go wrong can save you weeks of back-and-forth with lenders and prevent you from ending up with a loan that looks attractive on paper but doesn't suit your circumstances.

Refinancing Before Reviewing Your Current Loan Terms

Before submitting a refinance application, review your existing loan for break costs, discharge fees, and notice periods. Many borrowers start the process without understanding what it will cost them to leave their current lender. If your fixed rate period is ending, you may face break costs that exceed any savings from a lower interest rate. These costs are calculated based on the difference between your fixed rate and current wholesale rates, multiplied by your remaining loan balance and time left on the fixed term.

Consider a borrower in Annerley with $480,000 remaining on a fixed rate that expires in eight months. If wholesale rates have dropped significantly since they locked in, break costs could reach $12,000 to $18,000. Refinancing immediately would erase two years of savings from the new rate. Waiting until the fixed term expires eliminates that cost entirely. The loan review should also identify whether your current lender offers a retention rate that matches or beats what you can access elsewhere, which removes the need to refinance at all.

Timing Your Application Around Property Valuations

Lenders base your loan amount and interest rate on their valuation of your property, not on what you believe it's worth or what similar homes have sold for recently. If you purchased in Annerley during a price peak and values have since softened, the valuation may come in lower than expected. This affects your loan-to-value ratio, which determines whether you qualify for the rate advertised and whether you'll pay lenders mortgage insurance on the refinance.

In a scenario where a property was purchased for $820,000 and the owner wants to access equity for an investment deposit, a valuation of $780,000 instead of the expected $850,000 changes everything. The borrower's equity drops from $150,000 to $80,000, which may not be enough to fund the investment and cover refinancing costs. If you're refinancing to release equity, confirm recent comparable sales in your street or neighbouring streets before applying. If values have declined, delay the application until the market recovers or adjust your plans to reflect the lower equity available.

Applying for New Credit During the Refinance Process

Once you submit a refinance application, avoid applying for credit cards, car loans, or buy-now-pay-later accounts until settlement is complete. Lenders reassess your borrowing capacity before final approval, and new credit reduces the loan amount they're willing to offer. Even if the new account has a zero balance, the lender includes the full credit limit in their calculations, which can reduce your borrowing capacity by tens of thousands of dollars.

Switching Loan Structures Without Understanding the Trade-Offs

Refinancing often involves moving from one loan structure to another, whether that's switching to a variable rate, splitting between fixed and variable, or consolidating debt into your mortgage. Each structure has specific features and restrictions that affect how you can use the loan. A fixed interest rate typically removes access to offset accounts and redraw facilities, or limits how much you can contribute above the minimum repayment. If you rely on an offset account to manage irregular income or business cashflow, switching to a fully fixed loan removes that flexibility.

A borrower refinancing to lock in a rate after their fixed rate expiry might consolidate a $35,000 car loan and $18,000 in credit card debt into the new mortgage to reduce monthly repayments. While this improves cashflow, it converts unsecured debt into debt secured against their home and extends the repayment term from a few years to the life of the mortgage. The total interest paid on that $53,000 can exceed the original balances several times over. If consolidating debt, structure the loan so you can make extra repayments on that portion without penalty, and maintain the discipline to clear it within the original term.

Overlooking Lender-Specific Documentation Requirements

Each lender has different documentation standards, and missing or incomplete paperwork is the most common cause of delays during refinancing. Some lenders accept digital bank statements, while others require certified copies. Some will assess rental income at 80% of the lease amount, while others apply a lower percentage or require a depreciation schedule if you're refinancing an investment loan. If you're self-employed, some lenders need two years of tax returns and a letter from your accountant, while others accept a single year if your income has been consistent.

In our experience, borrowers who provide all requested documents within 48 hours of the initial request settle two to three weeks faster than those who provide documents piecemeal. Before you apply, confirm what your chosen lender requires and gather everything in advance. If you're refinancing to access equity for a deposit on a second property, the lender will also want a contract of sale or signed purchase agreement for the new property before they'll release funds.

Focusing Only on the Interest Rate

A lower interest rate doesn't always mean lower loan costs over time. Application fees, ongoing account fees, and the cost of features you don't use can outweigh the savings from a rate that's 0.15% lower. Some lenders advertise low headline rates but charge for offset accounts, redraw access, or additional repayments. Others bundle features at no extra cost but start with a slightly higher rate.

When comparing refinance offers, calculate the total cost over the period you expect to hold the loan. If you plan to sell or refinance again in three to five years, a loan with a $600 annual fee and a rate 0.20% lower will cost less than a no-fee loan with a higher rate. If you intend to hold the loan for ten years or more, the rate becomes the dominant factor. Also consider whether the loan allows you to improve cashflow by making extra repayments during high-income periods and redrawing when needed, or whether it locks you into a fixed repayment with no flexibility.

Refinancing Without a Clear Purpose

Refinancing should solve a specific problem or achieve a specific goal, not just respond to a feeling that you're paying too much interest. If your purpose is to reduce monthly repayments, extending the loan term will achieve that but increases the total interest paid. If your purpose is to unlock equity for an investment property, you need a valuation that supports the equity you think you have, and a lender that will allow you to access it without lenders mortgage insurance. If your purpose is to move from a fixed rate that's about to expire, confirm whether your current lender's revert rate is genuinely uncompetitive or whether it matches what you can access elsewhere once application costs are included.

Define your objective before you start, and structure the refinance application around that objective. Borrowers who refinance to "get a lower rate" without identifying what they'll do with the savings or how the new loan supports their broader financial position often end up with a loan that's marginally cheaper but less functional than what they had.

Refinancing a home loan is a financial decision that affects your repayments, equity, and flexibility for years. Taking the time to review your current loan, confirm your property valuation, and choose the right structure and lender reduces the risk of delays, unexpected costs, or a worse outcome than you started with.
