Mortgage Refinancing: When to Switch and How to Cut Costs

Refinancing in 2026 is less about chasing the lowest advertised rate and more about one clear question: will switching leave you better off once every cost is counted? The backdrop has changed. On February 3, 2026, the Reserve Bank of Australia lifted the cash rate target by 25 basis points to 3.85%. It rose to 4.10% on March 17, then to 4.35% on May 5. Higher rates affect repayments, lender pricing, and how long it takes to recover switching fees.

This guide sets out a practical framework for Australian homeowners and small property investors, with examples relevant to Queensland and the Gold Coast. It draws on primary sources such as ASIC’s Moneysmart, the RBA, APRA, and the ABS. It is general information only, not financial advice. For advice about your own circumstances, speak with a licensed credit adviser.

The Quick Verdict: When Switching Is Likely to Pay

Some situations point clearly toward refinancing. Switching tends to make sense when the gap between your current deal and a realistic new one is meaningful, and when you expect to hold the loan long enough to recover the costs. For many borrowers, that recovery period sits between 18 and 36 months.

• You hold at least 20% equity, so you can avoid paying fresh LMI on the new loan.
• The switch adds features you will actually use, such as a full offset account or a redraw facility.
• Your current lender will not match a better available deal after you ask.

Moneysmart suggests asking your current lender for a better deal first, and notes that you generally have more bargaining power with 20% equity or more. That phone call can sometimes deliver much of the benefit without the cost and paperwork of switching.

When to Wait or Renegotiate Instead

Refinancing is not always the answer. Lenders often offer retention pricing to keep existing borrowers, so asking first is a low-effort step.

• You are on a fixed rate and face break costs that could be large.
• You have less than 20% equity, so a new loan may trigger LMI.
• You plan to sell within a year or two, leaving little time to recover fees.
• Serviceability is tight. APRA has maintained the mortgage serviceability buffer at 3 percentage points as of May 28, 2026, meaning lenders assess you at a rate well above the one you would pay.
• The rate gap is marginal once fees are included.

Since February 1, 2026, APRA has limited high debt-to-income lending, a ratio of six or more, to 20% or less of new loans. The limit is applied separately to owner-occupiers and investors. If your borrowing is close to that threshold, a refinance that releases cash may be harder to arrange.

The Cost Checklist

Fees are where paper savings often disappear. Before comparing rates, map every cost a switch could involve.

• Fixed-rate break fee: charged if you exit a fixed loan early. This can be significant and varies with market conditions.
• Discharge or termination fee: charged to close your current loan.
• Application or establishment fee: charged to set up the new loan.
• Internal switching fee: charged if you move products with your existing lender.
• Valuation fee: charged by some lenders for a property valuation.
• State duties: in some cases duties may apply, so check with the lender.

If you expect to sell or refinance again soon, these fees can wipe out the benefit of a lower rate.

Run the Numbers, Step by Step

The government’s Mortgage Switching Calculator on Moneysmart estimates whether switching saves money and how long it takes to recover switching costs. Use it in three steps.

1. Enter all switching fees, not just the rate. Include break, discharge, application, and valuation costs.
2. Compare repayment paths between your current loan and the proposed one.
3. Find the breakeven month, the point at which cumulative savings overtake the upfront costs.

Read the calculator’s disclaimers. It gives estimates, not guarantees, and cannot capture every fee or future rate change. Under Australia’s National Credit Code, home-loan advertising must display a comparison rate that includes the interest rate and most fees, which helps you compare more fairly than headline rates alone.

Rate Versus Features

A slightly lower rate is not always best. Loan features can change the real cost more than a small rate difference.

Offset accounts are a good example. Lenders calculate interest daily on the loan balance minus the offset balance, so money in the offset reduces the interest you pay. Some accounts offer 100% offset, while others are partial. Package fees may apply, so weigh any annual fee against the interest saved. Redraw is different, letting you access extra repayments you have already made.

An Eligibility Reality Check

Approval is not automatic. Two APRA settings shape who qualifies: the 3 percentage point serviceability buffer, and the cap on high debt-to-income lending for borrowers with a ratio of six or more. These rules matter most for cash-out refinances and investor loans. A borrower with a thin monthly surplus, high debt-to-income ratio, or interest-only splits may find that a rate-led switch is hard to secure in practice.

Timing in 2026

The three RBA moves in February, March, and May 2026 pushed the cash rate target from 3.85% to 4.35%. Higher rates tend to lengthen breakeven timelines because the saving from a switch can be smaller relative to the fees involved.

Even so, refinancing activity remains substantial. In the March quarter 2026, owner-occupier external refinancing totalled $42.9 billion and investor external refinancing $25.3 billion, both seasonally adjusted, according to the ABS. Large volumes do not mean every switch pays off. They suggest borrowers need to be selective and run their own numbers.

How to Switch With Minimal Friction

If the maths supports a switch, a tidy process saves time and helps avoid extra cost.

1. Ask your current lender for a retention rate first.
2. Collect your documents early, including identification, income evidence, and loan statements.
3. Arrange the valuation the new lender requires.
4. Complete the discharge form for your existing loan.
5. Coordinate settlement timing so you avoid paying two loans at once.
6. Match the new loan term to your remaining term, rather than resetting to a fresh 30 years, so you do not extend interest unnecessarily.

Broker or Do It Yourself

Some borrowers manage a refinance themselves. Others use a mortgage broker to compare options and handle paperwork. A broker can be useful when your situation is complex, when you want a wider lender comparison, or when time is short. The trade-off is reliance on the broker’s panel and process. It can also help borrowers weigh broader property finance options before applying.

If you are comparing options on the Gold Coast, a refinancing mortgage specialist can review your current loan, compare features, manage paperwork, and run a home-loan health check. Go Mortgage Corp describes a process that reviews your current loan, clarifies your goals, compares options from more than 60 lenders, manages the application, and provides post-settlement support. Lender comparisons of this kind are not independently verified here, and no broker can promise approval or savings, so treat figures as a starting point for your own checks with Go Mortgage Corp or another licensed adviser.

Debt Consolidation Through a Refinance

Refinancing is sometimes used to roll other debts into the home loan. This can lower the interest rate on those debts, but it usually stretches them over a much longer repayment horizon.

Moneysmart cautions that a longer term can mean more total interest, even at a lower rate. Consolidation can make sense when it simplifies repayments and you keep the term short or make extra repayments. It is best avoided when it turns short-term debt into decades of home-loan interest. If you are on a fixed rate, include any break fee notice from your current lender.

Decide and Act: A Six-Point Checklist

Before you commit, work through these six questions. If you cannot answer them clearly, you are not ready to switch.

1. Goal: what do you actually want, a lower repayment, better features, or released equity?
2. Equity: is your equity at or above 20%, or will LMI apply?
3. Total switching costs: have you listed every fee, including any break cost?
4. Breakeven month: how long before savings overtake those costs?
5. Feature needs: do you need an offset or redraw, and is it worth any package fee?
6. Serviceability: will you meet the lender’s assessment under the 3 percentage point buffer?

Refinancing can cut costs when the decision is grounded in your own numbers and time horizon. Use primary sources such as Moneysmart to check the detail, and seek licensed credit advice for anything specific to your situation. Go Mortgage Corp and other licensed advisers can help test the assumptions before you decide.
