How to Refinance and Restructure a Geared Portfolio When Conditions Shift

Refinancing and restructuring a geared portfolio when conditions change means reassessing every loan’s rate, term, security and tax treatment, then reshaping them so they still support your strategy under higher interest rates, new tax rules and updated lender policies. Done well, you can lower risk, protect cashflow and keep borrowing power alive; done poorly, you can lock yourself into rigid structures, bigger repayments and messy tax outcomes.

This guide gives you a simple, decision‑grade process you can act on this week – whether you’re a home owner with one investment, a multi‑property investor, self‑employed, or running a small business alongside your portfolio.

1. Why refinancing geared portfolios matters more in 2026–27

1.1 The new environment: higher rates, tighter tax, stricter lenders

A geared portfolio is one where you use borrowed money – often at high loan‑to‑value ratios (LVRs) – to hold property and sometimes business assets. In Australia today, that gearing sits inside a very different environment to the one many investors borrowed in:

1. Higher interest rates. After the COVID‑era low of 0.10%, the Reserve Bank of Australia (RBA) has taken the cash rate back above 4%, including a 25 bps increase to 3.85% in February 2026 and another to 4.35% in May 2026. Many investors are rolling off 2–3% fixed rates into 6–7% variable rates.
2. New tax rules. From 1 July 2027, capital gains will face a minimum 30% tax rate, and negative gearing settings are tightening, especially for properties bought after 12 May 2026. Tax is now a risk to manage, not a free tailwind.
3. Tougher lending standards. APRA requires most lenders to test repayments with a ~3% buffer above the actual rate, making serviceability harder – especially for self‑employed borrowers and multi‑property investors.

If you borrowed for growth in 2017–2022 and haven’t revisited your structures since, there’s a high chance your loans are no longer optimised for this new environment.

1.2 Refinancing vs restructuring: what’s the difference?

It helps to separate two ideas:

• Refinancing = changing the loan contract (lender, rate, term, repayment type) while the security and purpose stay mostly the same.
• Restructuring = changing the shape of your debt – which property secures which loan, how many splits you have, how offsets are arranged, and which entity owns what.

You can:

• Refinance without major restructuring (e.g. same lender, new fixed rate and term).
• Restructure without changing lenders (e.g. split loans, remove cross‑collateralisation).
• Or do both at once.

For growth‑focused investors, the real power is usually in the restructure – then you use refinancing to get sharper pricing for that new structure. This builds on the principles in [/insights/restructuring-loans-growing-property-portfolios] and [/insights/designing-flexible-investment-loan-structures-geared-investors].

2. When should you consider refinancing or restructuring?

2.1 Trigger events you shouldn’t ignore

You don’t need to be constantly tinkering with your loans. But there are clear moments when doing nothing is riskier than taking action. Common triggers:

• RBA rate hikes or cuts that flow through to your repayments and yield. A 1% rise on a $1m portfolio adds around $10,000 per year in interest.
• End of fixed or interest‑only (IO) periods, especially if rolling from 2–3% to 6–7% and/or IO to principal & interest (P&I).
• Tax rule changes – such as the 2026–27 negative gearing and CGT reforms – that change the post‑tax economics of your portfolio. See [/insights/restructuring-existing-property-loans-new-tax-landscape] and [/insights/self-employed-business-owners-high-income-professionals-negative-gearing-cgt-strategy].
• Life and business changes – new child, separation, major health event, business downturn or windfall.
• Lender policy shifts that affect your borrowing power (e.g. living expense benchmarks, shading of rental income, treatment of trust distributions).

If one or more of these is happening and you haven’t reviewed your structure in the last 12–18 months, it’s time.

2.2 Signs your current structure is working against you

Common red flags in geared portfolios:

• Multiple properties all tied to one lender with a single, cross‑collateralised facility.
• Large non‑deductible home loan while investment loans sit on higher rates without offsets.
• Business debts or personal loans secured against the family home with no clear exit plan.
• Mixed‑purpose loan splits (e.g. one loan used for both home and investment), making tax deductibility hard to defend.
• Loans structured to maximise short‑term IO periods but now rolling to unaffordable P&I.

If two or more of these describe you, you don’t just have a rate problem – you have a structure problem.

3. Step-by-step: how to triage your geared portfolio this week

3.1 Map everything in one place

Before you touch a single loan, build a simple one‑page map of:

• All properties: address, ownership (you, partner, trust, SMSF, company), current value (estimate is fine).
• All loans: lender, limit, balance, rate, repayment type (IO vs P&I), remaining fixed/IO term, expiry date, security property.
• Cash buffers and offsets: balance, linked to which loan.
• Non‑property debts: car loans, personal loans, credit cards, business facilities.

This is the same mapping discipline we recommend for complex investors in [/insights/mortgage-brokers-property-investors-portfolio-builders] and for self‑employed clients running multiple entities.

3.2 Rank loans by “hurt factor”

Next, rank every loan on three axes:

1. Cost: current interest rate and whether it’s likely to spike soon (e.g. end of fixed term).
2. Tax treatment: non‑deductible (home), partially deductible (mixed purpose), fully deductible (investment/business).
3. Risk: security (is your home or key business asset at risk?), cashflow impact if the rate jumps, and any looming cliff (e.g. IO expiry).

A simple way is to score each 1–5 and total it. Loans with the highest total score get priority.

3.3 Set your objectives before touching products

Refinancing without clear objectives is just admin. Typical goals:

• Reduce non‑deductible interest as fast as possible.
• Protect cashflow and avoid forced sales if rates rise further or vacancy increases.
• Preserve or rebuild borrowing capacity for your next move.
• Clean up deductibility ahead of tax rule changes.

Write down your top 2–3 in order. They’ll drive your restructuring decisions.

4. Refinancing vs restructuring: which move suits which problem?

4.1 Common scenarios and the right tool for the job

Here’s a practical comparison of problems and likely solutions. Figures are indicative only.

4.2 Worked example: interest-only expiry in a higher-rate world

Say you have:

• Home loan: $700,000, 5.8% P&I, 25 years remaining.
• Investment loan: $600,000, 5.9% IO, 2 years left on IO.

Current repayments (approximate):

• Home P&I: ~$4,440 per month (25‑year term).
• Investment IO: ~$2,950 per month.

If the investment loan flips to P&I over the remaining 23 years at 6.2% (rates rise a bit more), repayments jump to about $4,110 per month – a $1,160 monthly hit.

Possible restructure:

• Refinance the investment loan to a sharper IO rate, extend IO responsibly (e.g. another 5 years), and split it so you have smaller tranches with staggered IO end dates.
• Channel surplus cash into the home offset, not the investment loan, to reduce non‑deductible interest.

You might end up paying slightly more on the investment loan over time, but you protect monthly cashflow and accelerate your home debt reduction, which is often the stronger overall result after tax.

5. Restructuring geared portfolios safely as conditions change

5.1 Avoiding cross‑collateralisation traps

Cross‑collateralisation is when one loan facility is secured by multiple properties, and sometimes one property secures multiple loans. It often happens by default when you grow with a single bank.

Risks in a changing environment:

• If one property underperforms or you need to sell, the bank can control sale proceeds and refuse to release security unless all loan‑to‑value ratios are back within their comfort zone.
• Refinancing just one property to a sharper lender becomes hard if others have fallen in value or don’t service well under stricter buffers.

A cleaner structure for most geared investors is standalone securities: each property (or logical pair) has its own loan, often with its own lender. This is a core theme in [/insights/designing-flexible-investment-loan-structures-geared-investors] and [/insights/restructuring-loans-growing-property-portfolios].

5.2 Using splits and offsets to direct cash where it does the most good

In a high‑rate, higher‑tax world, where your cash sits matters as much as how much you have.

Good practice:

• Keep non‑deductible home debt in a separate split with its own offset account.
• Keep each investment loan in its own split, ideally with separate offsets if you’re parking cash there.
• Use offsets, not redraw, if you may later change the property’s use (e.g. main residence to investment), so you don’t muddy the interest‑deductibility trail.

This echoes the principle that keeping separate home, investment and business splits makes future tax questions (and ATO audits) much easier to handle.

5.3 Aligning structures with upcoming negative gearing and CGT changes

With negative gearing set to shrink for many later purchases and a minimum 30% capital gains tax rate applying from 1 July 2027, structures that were fine five years ago may now be leaky.

Smart moves many investors are considering:

• Clarifying ownership so that properties with the strongest capital growth prospects sit with the person/entity that can best use the new CGT settings.
• Separating legacy, better‑taxed assets (e.g. pre‑12 May 2026 established properties or qualifying new‑builds) from newer properties that will be under tighter rules.
• Making sure deductible and non‑deductible loans are clearly separated before the rules change, so you can direct repayments and offsets where they add the most after‑tax value.

6. The self‑employed and small-business twist

6.1 Why refinancing is harder when income is lumpy

Self‑employed investors and small‑business owners face extra friction:

• Lenders may average two years of tax returns, shading income where it’s volatile.
• Company profits retained rather than paid as wages or dividends may not be fully recognised.
• Existing business facilities, overdue BAS or ATO payment plans can hurt borrowing power.

At the same time, your portfolio often plays double duty – as a nest egg and as security for business lending.

6.2 Don’t stretch short-term debt over 30 years by default

When refinancing, many lenders want to roll personal loans, tax debts or business overdrafts into your home or investment loan because the security is better and the headline rate is lower.

That can help cashflow, but be careful: stretching a 3‑year car loan over 25–30 years, even at a lower rate, can multiply total interest costs. If you consolidate, do it with a clear, shorter sub‑term and a plan to aggressively pay it down.

6.3 Separate home, business and investment risk

Where possible:

• Keep business loans secured against business assets or specific investment properties, not your family home.
• Maintain clean splits so you can show clearly which interest relates to income‑producing activities.
• Plan restructures jointly with your accountant and a broker who actually understands tax – not as an after‑the‑fact clean‑up.

The joint‑strategy approach described in [/insights/self-employed-business-owners-high-income-professionals-negative-gearing-cgt-strategy] and in our SMSF coordination content applies here too.

7. Lender policy, serviceability and timing your moves

7.1 How APRA buffers and HEM affect your options

Most lenders in 2026–27 are still applying:

• A minimum 3% serviceability buffer – they model your ability to repay at 3% above the actual rate.
• Their own version of Household Expenditure Measure (HEM) or similar benchmarks.

This means your existing repayments might feel fine, but on paper your borrowing power is limited.

Practical implications:

• If you wait until cashflow is tight or income dips to approach lenders, options shrink.
• Sometimes it makes sense to restructure early, while serviceability calculators are still in your favour, even if you’re not yet under pressure.

7.2 Staggering expiries to avoid future cliffs

One powerful restructuring tactic is staggering:

• Don’t let all your IO loans or fixed rates expire in the same 6–12 month window.
• When you refinance, consider splitting facilities so different portions roll at different times.

For example, instead of one $800,000 investment loan fixed for 3 years, consider two $400,000 splits with 3‑ and 4‑year terms. That way, if the RBA lifts rates again or lenders change policy, only part of your portfolio is exposed at once.

7.3 Channel strategy: one broker, or multiple direct relationships?

There’s a temptation to chase promotional cashback offers or shiny online tools. But for geared portfolios, the more important question is: who is steering the overall structure?

For most investors with more than one property, or with business/self‑employed income, it’s safer to have one coordinating broker who understands your full picture and works with your tax adviser – as explored in [/insights/mortgage-brokers-property-investors-portfolio-builders].

8. A one-week action plan you can actually follow

You don’t need to solve everything in seven days. But you can put the big rocks in place.

Day 1–2: Map and triage

• Build your portfolio map: properties, loans, splits, security, rates, terms, offsets, non‑property debts.
• Rank loans by cost, tax treatment and risk.
• Write down your top three objectives (e.g. reduce non‑deductible interest, protect cashflow, keep borrowing power).

Start by mapping and ranking each loan in your geared portfolio.

Day 3–4: Scenario modelling

• With a spreadsheet or your broker, model two or three future rate scenarios (e.g. +0.5%, +1%).
• Include upcoming IO or fixed rate expiries and new repayment amounts.
• For self‑employed, model a soft year of income – what happens to serviceability if your taxable income drops 20%?

Look at which loans cause the most pain under each scenario. Those are your restructure priorities.

Day 5: Strategy session (broker + accountant)

• Share your map and scenarios with a CPA‑grade broker and your tax adviser.
• Pressure‑test:
  • Which loans should we tackle first?
  • How can we separate deductible and non‑deductible debt cleanly?
  • Are we prepared for negative gearing and CGT changes with this structure?
• Agree a target structure on one page: who owns what, which lender holds which security, what splits you’ll have, and how offsets will be arranged.

Align refinancing and restructuring decisions with tax and entity advice.

Day 6–7: Implement first moves

You don’t have to refinance everything at once. Instead:

• Tackle one or two high‑priority loans where the benefit is clearest.
• Focus first on:
  • Reducing non‑deductible interest; and/or
  • Removing the worst cross‑collateralisation; and/or
  • Managing near‑term IO/fixed expiries.
• Set up separate offsets aligned with your new splits.

Lock in a follow‑up checkpoint in 3 months to keep moving the rest of the plan.

Break your refinance and restructure into a focused one-week plan.

FAQs: Refinancing and restructuring geared portfolios

1. How often should I refinance my investment property loans?

Most geared investors should review their loans every 12–24 months and seriously consider refinancing whenever there’s a major rate shift, end of a fixed or IO period, or a change in life or tax rules. That doesn’t mean you refinance every time – sometimes a simple repricing with the current lender is enough – but you should compare and check the structure regularly.

2. Is extending interest-only periods still a good idea with higher rates?

It can be, but it’s no longer an automatic “yes”. Extending IO can help protect cashflow and preserve buffers, especially for investors planning to hold assets long term. However, higher rates and tighter tax rules mean you need to model total interest costs and make sure you’re still reducing non‑deductible home debt at a sensible pace.

3. Should I refinance before or after the 2027 CGT and negative gearing changes?

In many cases it makes sense to restructure and clean up loan splits before big tax reforms take effect, so you can direct repayments and offsets to the right places. But the answer depends on your specific properties, purchase dates and ownership structures. Coordinate with a broker who understands tax and your accountant before making major moves.

4. Can I fix my rates again to protect against further RBA hikes?

You can, but fixing is a risk‑management tool, not a bet on the future. In today’s environment, many investors choose a mix of fixed and variable splits to balance certainty and flexibility. Before fixing, consider likely sale or restructure plans, break‑cost risk, and how fixed rates sit relative to your lender’s current variable offers.

5. Is it worth refinancing if I have a sizeable tax bill this year?

A tax bill doesn’t automatically stop you refinancing, but unpaid ATO debt or late BAS can make some lenders nervous. Often the best approach is to be upfront: your broker can identify lenders more comfortable with recent clean‑up and structure your application accordingly. In some cases, a refinance can include a shorter‑term sub‑split to clear high‑interest tax or personal debt with a clear payoff plan.

Key takeaways

• Refinancing and restructuring are different but complementary: structure first, price second.
• Map your entire portfolio and triage loans by cost, tax treatment and risk before touching products.
• In a world of higher rates and tighter tax rules, separating deductible and non‑deductible debt is more valuable than ever.
• Avoid or unwind unnecessary cross‑collateralisation so you retain control when conditions change.
• Self‑employed and small‑business investors need to be extra careful about not stretching short‑term debts over 30 years and about keeping home, business and investment risks separate.
• The best time to restructure is before you’re in distress, while serviceability and options are still on your side.
