Your bank is counting on your inertia. Here is what it costs you — and how to take it back.
If you have had your home loan with the same lender for more than two years, there is a meaningful chance you are paying more than you need to. Not by a little. In many cases, by 0.5% to 1.2% per annum more than what is available to a new borrower at the same bank, with an identical risk profile.
This is called the loyalty tax. It exists because lenders compete aggressively for new customers with headline rates and cashback offers, then rely on existing customers not bothering to switch once they are settled. ASIC has documented this pattern across multiple reviews of the mortgage market. The average gap between what existing borrowers pay and what new borrowers pay at the major banks has widened consistently since 2022.
Loan balance: $650,000. Remaining term: 23 years. Current rate: 6.24% (existing customer rate at a major bank). Available rate via broker: 5.49% (new customer rate, same or comparable lender).
That $90,000 is not a hypothetical. It is the money that currently sits in your lender's profit column instead of yours. A broker does not need to do anything exotic to recover it. They need to pick up the phone and ask for a better deal — or move you to a lender that offers one.
"What rate am I on compared to your best available rate for a new customer with my LVR and credit profile?" If the gap is more than 0.25%, it may be worth speaking with a mortgage broker. That conversation typically takes 20 minutes and is provided at no cost.
The friction of refinancing is mostly psychological. Lenders and brokers who handle refinances every week know the paperwork intimately — it takes the same documents you used to get your original loan, most of which you already have. The typical timeline from first conversation to settlement is four to six weeks. The typical cost to switch, inclusive of discharge fees and any application fees, ranges from $300 to $1,200 depending on your lender and loan structure.
On a $650,000 loan saving 0.75%, you recover that switching cost in approximately six to ten weeks of reduced repayments. Every payment after that is pure saving.
Refinancing is not always the right move. Here is the honest test.
Not every refinance is worth doing. There are situations where the cost of switching, the structure of your loan, or your short-term plans make it financially neutral or even counterproductive. This chapter gives you the tools to make an objective assessment before you do anything.
The most important number in any refinance decision is the break-even point: how many months until your savings exceed your switching costs.
Step 1: Add up your switching costs — discharge fee (typically $150–$400), any early repayment charge if you are on fixed, application/settlement fee at the new lender (often waived), legal/valuation fees (typically $0–$600 via broker).
Step 2: Calculate your monthly saving (rate difference × loan balance ÷ 12).
Step 3: Divide Step 1 by Step 2. That is your break-even in months.
If you plan to stay in the property longer than your break-even period, refinancing is financially rational.
Breaking a fixed rate loan can cost anywhere from $0 to $30,000+ depending on when you fixed, what wholesale rates have done since, and your lender's methodology. Always request a break cost figure in writing before making a decision. The number may surprise you either way.
The complete eight-step process — what happens when, and what you need to do at each stage.
A well-run refinance is not stressful. It is a series of clearly defined steps with predictable timelines. Here is what the process looks like when a broker manages it properly.
A 30-minute call to understand your current structure, goals, and situation. Your broker will review your rate, loan type, offset balance, redraw, and any features worth preserving. This is also where equity access, debt recycling, and investment goals are discussed.
Your broker runs your profile across 30+ lenders to identify the best fit — not just the lowest rate, but the right structure, features, and lender policy for your situation. A rate that looks good on paper can cost you money in practice if the offset account is poorly designed or the serviceability model doesn't suit your income type.
You will need: two most recent payslips, last two years' tax returns and Notices of Assessment, last three months' bank statements, most recent home loan statement, and your most recent council rates notice (for property address confirmation). Self-employed borrowers will additionally need their last two years' business financials and an accountant's letter.
Your broker lodges the application with the chosen lender. Most major lenders now process digitally and can turn around conditional approval in 24–72 hours for straightforward applications.
The new lender orders a valuation of your property. This is typically a desktop valuation (using automated tools and comparable sales data) for LVRs below 80%. Higher LVR applications may require a physical inspection. Values occasionally come in below expectation — your broker will manage this if it occurs.
Once valuation is confirmed and credit assessment complete, formal approval is issued. Your broker reviews the loan documents before they reach you and flags anything requiring clarification.
You sign the new loan documents. Your new lender coordinates the discharge of your existing mortgage directly with your current lender — you do not need to chase this. Settlement typically occurs five to fifteen business days after signing.
Funds transfer, your old loan closes, and your new loan begins. Your broker confirms the rate is correct on your first statement and sets a calendar reminder to review your position again in 12–18 months.
In a broker-led refinance, your job is to provide documents and sign when asked. The research, lender liaison, valuation coordination, discharge management, and rate checking on settlement is handled by your broker. If you find yourself doing significant administrative work, something is wrong.
The tax-effective strategy the ATO allows — and most borrowers have never heard of.
Debt recycling is one of the most powerful legal wealth-building strategies available to Australian homeowners. It is not a tax scheme or a loophole. It is a structured approach to converting non-deductible home loan debt into deductible investment debt — simultaneously paying off your mortgage faster and building an investment portfolio, using the same cash flow.
The Australian Tax Office distinguishes between debt used to buy or improve income-producing assets (deductible) and debt used to purchase your home (non-deductible). The interest on an investment loan is deductible against your taxable income. The interest on your home loan is not.
Debt recycling exploits this distinction legally and deliberately. Each cycle of the strategy converts a portion of your non-deductible home loan into deductible investment debt. Over time, the proportion of your debt that is tax-deductible grows — reducing your tax liability while your investment portfolio grows in parallel.
The ATO determines deductibility based on the purpose for which borrowed funds are used — not the security against which they are borrowed. The $20,000 must go directly to the investment purchase. If it touches your personal account or is used for anything else first, the deductibility argument is compromised. This is a strategy that requires clean record-keeping and, ideally, a dedicated investment loan split from your home loan. Your broker structures this correctly from the start.
Consider a homeowner on a $150,000 combined household income (marginal tax rate 37% plus 2% Medicare = 39%). They have $500,000 remaining on their home loan and begin debt recycling $50,000 per year.
That $1,131 tax refund goes straight back onto the home loan. The portfolio generating dividends also sends those back to the home loan. The compounding effect over 10 to 15 years, when modelled properly, can result in a portfolio worth $600,000 to $900,000 while the home loan is paid off faster than the standard schedule — all from the same underlying cash flow.
Real scenarios, common structures, and what the results actually look like.
Debt recycling works across a range of income levels and loan sizes. The strategy is not exclusive to high earners — in fact, it often produces proportionally stronger results for households in the 32.5% marginal tax bracket than those at the top rate, because the investment returns compound more freely relative to the tax saving.
Debt recycling requires a home loan with a genuine redraw facility — not just an offset account. The most common structure used by brokers is a split loan:
The investment vehicle matters. For debt recycling to work optimally, your investments need to be income-producing (to generate deductible distributions that can be recycled back to the home loan) and growth-oriented (to compound the portfolio over time).
| Investment Type | Income Generation | Suitability | Notes |
|---|---|---|---|
| Australian shares / ETFs | Dividends + franking credits | Commonly used | Franking credits boost effective yield for Australian taxpayers. This is a general observation, not a product recommendation. |
| Broad market index funds (examples: diversified ASX-listed ETFs) | Quarterly distributions | Commonly used | Low cost, diversified. Specific products should be selected with a licensed financial adviser based on your circumstances. |
| Investment property | Rental income | Good | High entry cost; works but requires more complex loan structuring |
| Managed funds | Regular distributions | Good | Less tax-efficient than direct shares in some structures |
| Cryptocurrency | Variable | Poor | Not income-producing by nature; ATO scrutiny; not recommended for this strategy |
Australian company dividends carry franking credits representing tax already paid at the corporate level. For a shareholder in the 39% bracket, franking credits effectively add 1.5–2% to the after-tax yield of a fully franked Australian share portfolio. This materially improves the debt recycling numbers and is one reason Australian shares are particularly well suited to the strategy.
Combined income: $160,000. Home loan: $620,000 at 5.74%. Available surplus after expenses and mortgage: $2,500/month. Marginal tax rate (combined effective): 37%.
Without debt recycling: After 10 years they have paid $310,000 off their home loan. Investment portfolio: $0. Net wealth increase attributable to financial strategy: $310,000.
With debt recycling: After 10 years the home loan is $590,000 (roughly equivalent — the strategy is not primarily about accelerating home loan repayment, it is about building the portfolio). Investment portfolio (assuming 8% average total return including dividends): approximately $480,000. Tax refunds received and recycled over 10 years: $42,000. Net wealth position: $1,070,000 in total assets (home equity plus portfolio).
General information only. This is an illustrative modelling scenario based on the specific assumptions stated above.

You do not have to choose between paying off your mortgage and building a portfolio. Here is how to do both.
The instinct to pay off the home loan before investing is understandable — it is the risk-averse choice, and for many households it is the right one. But for households with stable income, adequate emergency reserves, and a long-term horizon, the opportunity cost of sequencing (pay off home first, then invest) is significant and often underestimated.
The mathematical argument for investing alongside your mortgage rather than after it comes down to compound growth and the cost of delayed entry. A $10,000 investment made at age 35 (with a 25-year growth runway to age 60) at 8% annual return becomes approximately $68,500. The same $10,000 invested at age 45 (with a 15-year runway) becomes approximately $31,700. The 10-year delay cost $36,800 per $10,000 invested.
Multiplied across the $30,000–$50,000 per year a household might invest during the "paying off mortgage first" phase, the sequencing cost runs to several hundred thousand dollars in forgone portfolio value.
Three to six months of total household expenses in accessible savings or offset, separate from any redraw facility. This is not optional. A market correction that forces you to sell investments to cover a broken boiler is a compounding disaster — you crystallise losses at the worst time and undermine the entire strategy.
