Avoid These 5 Refinancing Mistakes That Cost Thousands

Refinancing can reduce your monthly repayments, release funds from your property, or shift you onto a loan structure that actually supports your goals.

Many Oran Park households are sitting on home loans they took out three or four years ago when the suburb was still filling in around them. Back then, getting approved was the priority. Now, with established equity and a clearer sense of what you need from your mortgage, it's worth checking whether your current loan still serves you. That means looking at the rate, the features, and whether it aligns with what you're planning over the next few years.

Waiting Until Your Fixed Rate Ends Without Reviewing Earlier

You don't need to wait until your fixed rate expires to start assessing your options. Most fixed rate loans allow you to refinance before the term ends, though there may be break costs involved. Those costs are calculated based on the difference between your current fixed rate and the rate your lender can now earn on the wholesale market for the remaining period. If rates have risen since you locked in, break costs are often minimal or zero. If rates have fallen, the cost can be significant.

Consider a household in Oran Park who fixed at 2.1% three years ago and still has 18 months remaining. If current rates sit higher than their locked rate, the lender hasn't lost future interest income by letting them out early, so the break cost might be a few hundred dollars or nothing at all. In that scenario, moving to a variable loan with an offset account and redraw could deliver more flexibility without a substantial penalty. We see this regularly with clients who assume they're locked in and miss months of potential savings or functionality.

If you're coming off a fixed rate in the next six months, that's also the time to review. Lenders are offering retention rates to keep existing customers, and comparing those against what's available elsewhere often uncovers a margin worth acting on. Starting a refinance application eight to twelve weeks before your fixed term ends gives you time to assess offers properly and settle into a new loan without rolling onto your lender's standard variable rate.

Refinancing Only for Rate Without Checking Loan Features

A lower rate matters, but the structure of your loan often determines how much you actually save. Two loans at the same rate can perform very differently depending on whether they include an offset account, allow extra repayments without restriction, or offer portability if you move.

An offset account holds your salary and savings in a transaction account linked to your mortgage. The balance in that account reduces the portion of your loan that accrues interest each day. If you have a mortgage of $600,000 and $40,000 sitting in offset, you're only charged interest on $560,000. That reduces your interest costs without locking funds away, so you can still access that $40,000 whenever you need it. Redraw facilities allow you to make extra repayments and withdraw them later, but access can be slower and some lenders place restrictions on how much you can pull back out.

In our experience, households in Oran Park who are managing childcare costs, school fees, or irregular income benefit more from the liquidity of an offset than a slightly lower rate on a basic loan. The ability to park a tax return, bonus, or sale proceeds in offset and reduce interest daily without losing access makes a tangible difference to cash flow across a year.

Assuming Your Equity Isn't Enough to Access Funds

Oran Park has seen consistent value growth since the suburb's early stages, and many properties purchased in the last five to seven years have built up usable equity. If you bought when the town centre was still under construction, your property may now be worth substantially more than your original purchase price. That equity can be accessed through refinancing, either to fund renovations, purchase an investment property, or consolidate other debts into your mortgage at a lower rate.

Lenders generally allow you to borrow up to 80% of your property's current value without paying lenders mortgage insurance. If your property is now worth $900,000 and your loan balance sits at $650,000, you could access up to $720,000 in total lending, which releases $70,000 in usable equity. That might fund a deposit on an investment property, cover a renovation that increases your home's functionality, or clear personal loans and credit card balances that carry much higher interest.

We regularly work with clients who didn't realise they had this option available. They've been paying down their mortgage steadily while also servicing a car loan at 8% or a personal loan at 11%, when they could have consolidated those into their home loan and reduced the blended cost. The refinance process includes a current valuation of your property, and that valuation often reveals how much capacity you actually have. If you're considering accessing funds for any reason, a loan review will clarify whether refinancing makes sense and what the repayment impact would be.

Comparing Advertised Rates Without Understanding What You Qualify For

The rates you see promoted online are typically reserved for borrowers with a loan-to-value ratio below 70% or 80%, a clean credit file, and income documentation that meets full verification requirements. If your deposit is smaller, you're self-employed, or your credit history includes a default or missed payment from years ago, the rate you're offered will likely be higher than what's advertised.

That doesn't mean refinancing isn't worth pursuing. It means the comparison needs to be between what you're currently paying and what you can realistically access now, not what someone with different circumstances might qualify for. A household currently on a variable rate of 6.5% who can refinance to 6.1% will still reduce their repayments and total interest, even if the advertised rate they saw was 5.8%. The saving is real, even if it's not the headline figure.

Lenders assess refinance applications using the same serviceability buffers they apply to new purchases. That means they'll test whether you can afford repayments at a rate roughly 3% higher than the actual loan rate. If your income has dropped, your expenses have increased, or you've taken on new debt since your original loan was approved, you may not qualify for the full amount you're hoping to borrow. Running a borrowing capacity assessment before you start the formal application will show you where you sit and whether any adjustments are needed to strengthen your position.

Ignoring the Cost of Staying Where You Are

Refinancing involves a valuation fee, application costs, and sometimes discharge fees from your current lender. Those costs typically sit between $1,000 and $2,500 depending on your loan size and lender. Many borrowers weigh that upfront cost against the effort involved and decide to stay put. The issue is that staying on a loan that's 0.4% or 0.5% higher than what's available elsewhere compounds over time, and the gap widens the longer you wait.

If you're paying $3,000 or $4,000 more in interest each year because your rate is higher than what you could access elsewhere, that's $12,000 to $16,000 over four years. Set against a $2,000 refinancing cost, the case for moving becomes clear. The larger your loan and the wider the rate gap, the faster those savings accumulate. Some lenders will also cover your refinance costs as part of their offer, particularly if you're bringing across a loan above a certain size.

A home loan health check is a structured review of your current loan against what's available now, taking into account your rate, features, remaining loan term, and any upcoming changes in your circumstances. It will show you whether refinancing delivers a measurable benefit or whether your current loan is still competitive. That assessment costs nothing and removes the guesswork from the decision.

If your loan is more than two years old, your household or income has changed, or you're about to come off a fixed rate, it's worth having that conversation now rather than waiting until refinancing feels urgent. Call one of our team or book an appointment at a time that works for you.
