Refinancing simply means replacing your current home loan with a new one, either with your existing lender or a different one. Done at the right moment, it can lower your repayments, unlock features you actually use, or free up equity (the share of your home you actually own) for renovations or your next move. Done at the wrong moment, the costs can quietly cancel out the savings. This guide walks through the common triggers, the real costs, the typical timeline, and the signs it may not be worth it for your situation in Perth.
The common triggers for refinancing
Most people start thinking about refinancing because of one or more of the following.
Your fixed rate is expiring
When a fixed term ends, your loan usually rolls onto the lender’s standard variable rate, which is often higher than what a new customer would be offered. This rollover point is one of the most common moments to review your options. It is worth comparing well before the fixed period finishes rather than letting it lapse. If you are weighing up what to do next, our explainer on fixed versus variable home loan rates in Perth covers the trade-offs.
Rates have moved
If lender rates have shifted since you took out your loan, the gap between your current rate and what is available now might be enough to justify a switch. We will not quote rate figures here because they change constantly, so treat any number a calculator gives you as a starting point and confirm current figures before acting.
You have built equity
As you pay down the loan and (in many cases) as the property value rises, your loan-to-value ratio (LVR, your loan as a percentage of the property value) falls. A lower LVR can open the door to sharper rates and may remove the need to pay lenders mortgage insurance (LMI, the one-off insurance payable when you borrow more than 80% of the value) on the refinanced amount.
You want to access equity
Refinancing can let you borrow against the equity you have built, for example to fund renovations, cover a major expense, or put a deposit on an investment property. Accessing equity increases your loan balance, so it pays to be clear on the purpose and the repayments before going ahead.
You want better features or to consolidate debt
Some borrowers refinance to gain features their current loan lacks, such as an offset account (a transaction account linked to your loan, where the balance reduces the interest you are charged) or a flexible redraw (the ability to pull back extra repayments you have made). Others fold higher-interest debts like credit cards or a car loan into the home loan to simplify repayments. Consolidation can reduce monthly outgoings, but stretching short-term debt over a 30-year term can cost more in total interest, so the maths needs checking carefully.
Your circumstances have changed
A new job, a growing family, a separation, or a shift in income can all change what you need from a loan. Refinancing is one way to restructure repayments around your current reality.
The costs of refinancing
A refinance is rarely free. The headline saving means little until you subtract these.
- Discharge fee. Your existing lender typically charges a fee to close out and release the loan.
- Break costs. If you are on a fixed rate and exit early, the lender may charge break costs, which can be significant depending on how rates have moved since you fixed. This is one of the biggest reasons a refinance can fail to stack up mid-fixed-term.
- Application and valuation fees. The new lender may charge to set up the loan and to value your property, although some waive these as part of a deal.
- LMI again. If your LVR is above 80%, you may have to pay LMI on the new loan, even if you paid it the first time. LMI is generally not transferable between lenders, so this can be a meaningful cost if your equity position is still tight.
A useful rule of thumb is to add up every cost, then work out how many months of savings it takes to recover them. If that break-even point is years away, the case is weaker. A licensed broker can run these numbers properly against your actual loan, and you can find a Perth broker through independent brokers to do exactly that.
The typical timeline
As at June 2026, a standard refinance usually takes roughly 4 to 8 weeks from application to settlement, though this varies with lender processing times, how quickly the valuation is booked, and how complete your paperwork is. Confirm current timeframes with your broker, as conditions change.
In broad terms the steps are: gather your documents and compare options, submit the application, the lender orders a valuation and assesses your borrowing position, formal approval is issued, loan documents are signed, and finally the old loan is discharged and the new one settles. Getting your payslips, statements and identification ready early is the single most effective way to keep things moving.

Signs it may NOT be worth it
Refinancing is not always the right call. Some honest red flags.
- You are deep in a fixed term. Break costs can wipe out the benefit, particularly if rates have fallen since you fixed.
- The savings are small. If the rate difference is marginal, the discharge, application and valuation fees may take years to recover.
- Your LVR is above 80%. A fresh LMI bill can easily outweigh a modest rate improvement.
- You are close to selling. If you plan to move within a year or two, you may never reach the break-even point on the switch costs.
- Your credit or income position has weakened. A new application is a fresh assessment, and approval is not guaranteed, so there is little upside in disturbing a loan you already hold.
If any of these apply, sometimes the better move is simply to ask your current lender for a sharper rate before going through a full switch.
How to weigh it up for your situation
The honest answer to “should I refinance” is “it depends”, and it depends on numbers specific to you: your rate, your balance, your LVR, your fixed-term status, your goals, and the total switch costs. The right approach is to compare your current loan against real offers and check that the savings clearly beat the costs over a sensible time frame.
