The mortgage market moves faster than most homeowners realise. The 'loyalty tax' - the rate premium paid by existing customers vs new customers - has averaged 0.5-1.0% in Australia over the past decade. On a $600,000 loan, that's $3,000-$6,000 per year staying with the wrong lender. But refinancing isn't always the right move.

• The 0.5% rule of thumb: A rate reduction of 0.5% or more on a substantial loan balance ($400,000+) typically justifies refinancing after accounting for switching costs. On a $500,000 loan at 0.5% lower rate, annual interest saving is $2,500 - recovering $2,000-$3,000 in switching costs within 12-15 months
• Your current rate vs market rate: The first step is identifying your current interest rate and comparing it to what new customers are being offered. Check your lender's new customer rate on their website - if your rate is 0.3%+ higher, call the retentions team first. Many lenders match or beat the market for existing customers who threaten to leave, without any formal refinancing costs
• Circumstances that favour refinancing: Significant equity gain (property appreciated, LVR dropped below 80% - removing LMI risk), life change requiring different loan structure (IO to P&I, fixed to variable, adding offset account), consolidating high-rate debt at the mortgage rate, or cash-out for renovation at rates well below personal loan rates
• Circumstances where refinancing is poor value: Fixed rate with material break cost (see below), LVR still above 80% (new LMI may apply), less than 2 years remaining on loan (not enough interest remaining to recover costs), poor credit events since original loan (may not qualify for better rate), or rate difference is negligible after all costs
• The loyalty tax negotiation: Before formally refinancing, call your lender's retention team and ask for a rate match to a competitor's offer. Bring a written competitor offer (pre-approval or advertised rate with product name). Many borrowers achieve 0.2-0.5% rate reductions without switching - free money requiring 30 minutes of effort

Breaking a fixed rate home loan before the fixed term expires can trigger significant break costs - sometimes tens of thousands of dollars that completely negate any rate saving from refinancing. Understanding how break costs are calculated is essential before acting.

• What triggers a break cost: Any event that ends the fixed rate period early - refinancing to another lender, selling the property, making extra repayments above the allowed annual limit (typically $10,000-$20,000), or switching to a variable rate within the fixed term
• How break costs are calculated: The formula is broadly: (Fixed rate - Current wholesale rate for remaining term) × Remaining loan balance × Remaining term in years. If wholesale rates have fallen since you fixed, the break cost is higher. If wholesale rates have risen above your fixed rate, the break cost may be zero (or even a 'break gain')
• Example - fixing at 2.5% in 2021: Many Australians fixed at 2.5-3.0% in 2021-22. As variable rates rose to 6%+ by 2023, wholesale rates also rose above fixed rates - meaning break costs were low or nil. Borrowers who fixed at 2.5% could refinance in 2023 with minimal break cost AND a lower rate than they'd pay on a new fixed term
• Example - high break cost scenario: Fixing at 6% with 3 years remaining when wholesale 3-year rates drop to 4.5%. Remaining balance $500,000. Break cost ≈ (6%-4.5%) × $500,000 × 3 years = $22,500. This makes refinancing unviable - the rate saving would take many years to recover the break cost
• How to find your break cost: Call your lender and ask for a break cost estimate. Provide the date you intend to refinance and the loan account number. The estimate is typically valid for 5 business days. Lenders are not required to provide the formula - just the resulting figure. For material amounts, ask the lender to confirm in writing

Cashback refinancing offers - where a lender pays $2,000-$6,000 cash on settlement - proliferated in 2021-2023. They can represent genuine value or a trap that locks you into an uncompetitive rate. Know the difference.

• How cashbacks work: A lender offers $3,000-$6,000 paid to the borrower on settlement of a refinanced loan above a minimum amount (typically $250,000-$500,000). The cashback is intended to cover switching costs and entice borrowers with an upfront benefit
• The rate trap: If the cashback lender's ongoing interest rate is 0.3% higher than the best available rate on your loan size, the $3,000 cashback is recovered by the lender through higher interest within 2-3 years. Net cost over 5 years: significant. Always compare the total interest cost over a 3-5 year period, not just the cashback amount
• Tax treatment of cashbacks: Cashback payments are generally not assessable income for owner-occupier home loans - they are treated as a reduction in the cost of the loan, not as income. Seek confirmation from your tax adviser for investment property refinancing where the tax treatment may differ
• Clawback period: Many cashback offers include a clawback clause - if you refinance again within 24 months, you must repay some or all of the cashback. This effectively locks you in for 2 years. If the rate becomes uncompetitive within that period, you're trapped or pay to leave
• When cashbacks are genuinely valuable: A cashback from a lender whose rate is genuinely competitive (within 0.1% of market best), with no clawback period or a short clawback, and where switching costs are meaningful, represents real value. The cashback covers costs and the ongoing rate is sustainable. These deals exist - they just require careful analysis rather than headline hunting

Refinancing is the point at which your LVR (loan-to-value ratio) is formally recalculated against the current property value. For many borrowers, this creates opportunities - or risks - not present at original purchase.

• New valuation at refinancing: The new lender orders a valuation of your property (usually a desktop valuation for straightforward residential property, or a full valuation for unusual properties). The assessed value determines your LVR: outstanding loan balance ÷ new property value
• Sub-80% LVR removes LMI risk: If you purchased with a 10% deposit and paid LMI, your LVR may now be below 80% due to repayments and price growth. The new lender will not charge LMI on an 80% LVR loan - eliminating a major cost that existed at original purchase
• Equity release via cash-out refinancing: If your property value has grown significantly, refinancing allows you to access equity by borrowing a higher amount. A property worth $900,000 with a $400,000 loan (44% LVR) allows refinancing to $720,000 (80% LVR) - releasing $320,000 in equity for investment, renovation, or other purposes. Interest on the released equity may or may not be deductible depending on its use
• LVR pricing tiers: Lenders price mortgages at LVR tiers - rates are typically best at below 60% LVR, moderate at 60-80%, and higher at 80-90%. If your LVR at refinancing has dropped into a lower tier, you may qualify for a better rate regardless of advertised rates
• Negative equity risk: In falling markets, property values at refinancing may be below the original purchase price. If outstanding loan balance exceeds current value (LVR above 100%), refinancing is typically impossible - no lender will accept negative equity. In this situation, continue with the existing lender and focus on reducing the loan balance

Refinancing is simpler than most people expect - but requires attention to sequencing and document preparation. Here's the complete process from decision to settlement.

• Step 1 - Rate and cost comparison: Use comparison sites (Canstar, RateCity) to identify the best variable and fixed rates. Factor in: comparison rate (includes most fees), offset account availability, extra repayment flexibility, redraw facility, and annual fees. Calculate true savings over 3 years after switching costs
• Step 2 - Pre-approval application: Apply for pre-approval with your preferred lender. Prepare: 2 years of tax returns or PAYG summaries, 3 months of payslips, 3 months of bank statements, existing mortgage statements, and photo ID. Pre-approval typically takes 2-7 business days for straightforward applications
• Step 3 - Valuation: The new lender orders a valuation. For owner-occupied residential property under $1.5M in metropolitan areas, desktop valuations are common (no physical inspection). Full valuations take 5-10 business days and may require access to the property
• Step 4 - Formal approval and loan offer: After valuation, the lender issues formal approval and a loan contract. Review carefully: interest rate, loan term, offset account details, extra repayment caps, redraw fees, and any annual package fees. Your solicitor or conveyancer can review the mortgage documents
• Step 5 - Settlement: Your new lender pays out the old loan directly. The old lender discharges the mortgage. Discharge fees from the old lender ($150-$350 typically), registration of the new mortgage (state government fee, $100-$200), and new lender establishment fees (if any) are deducted at settlement. The process typically takes 3-6 weeks from application to settlement for a straightforward refinance
