Investment Property Loans — Structure Matters More Than the Rate
Whether you're buying your first investment property or reviewing an existing portfolio, the way your loans are structured affects your cash flow, borrowing capacity, and long-term outcome.

No cost, no obligation.
We will review your current position, goals, and available lending options.
Investment property lending in Australia is more nuanced than ever. Getting the right loan structure — not just the lowest rate — is what separates investors who build wealth from those who get stuck.
This guide covers how investment loans work, how to use your home equity to purchase your next investment property, and what the 2026 Budget changes mean for the way you hold and structure property.

2026 Federal Budget — what changed for property investors
From 1 July 2027, negative gearing on established residential properties purchased after 12 May 2026 will no longer be able to offset wage income. The 50% CGT discount will also be replaced with a 30% minimum tax for individuals and trusts.
Properties already owned on Budget night are grandfathered. New builds retain full negative gearing. Properties held inside superannuation (SMSFs) are unaffected.
This changes how investment property should be structured — but it does not change the fundamentals of property as a long-term wealth strategy. This guide explains what it means for borrowing, structure, and your options.

A smarter, simpler way to approach property investing
Property investing works best when the finance is structured correctly from the start. This page steps through the key decisions that matter: loan types, structure, equity, cash flow and how all of this fits into your long term plan. Whether you are buying your first investment property or growing a portfolio, the aim is to give you clarity and practical next steps.
Why property investing works for Australians
Property can be a powerful way to build wealth because it combines several advantages:
1
Leverage
where you use a deposit plus the bank’s money to control a larger asset.
2
Rental income
tenants help cover the holding costs over time.
3
Capital growth
as property values have generally increased over the long term.
4
Tax structure
loan interest and property expenses remain deductible against rental income.Confirm borrowing capacity before making offers
5
Structure now matters more than ever
with CGT and negative gearing rules changing, the entity and structure you use to hold investment property (personal name, trust, or SMSF) has a larger impact on your long-term outcome than it did previously.
The part that is often overlooked is how important the loan structure is. Two investors can own very similar properties but achieve very different outcomes because their lending, cash flow, and strategies are configured differently.
For properties purchased from 12 May 2026, rental losses on established property can still be carried forward and offset against future rental income or capital gains — they simply cannot reduce wage income from 1 July 2027. New builds and SMSF-held properties retain broader deductibility.
Investment property loan types explained
The right loan type depends on whether you are focused on growth, cash flow, debt reduction, or a mix of all three. Below are the main options and how investors commonly think about them.
Interest only for cash flow and flexibility
Interest only (IO) loans can keep your repayments lower and free more cash flow for buffers, improvements or additional investments. They are often used when you are in the growth phase and want to keep your non deductible home loan as the main focus for repayments.
Principal and interest for long term debt reduction
Principal and interest (P&I) repayments steadily pay down the loan balance over time. This can work well for higher yielding properties, or when you are closer to retirement and want your debt levels to reduce each year.
Variable, fixed or a mix of both
Variable loans offer flexibility and easier access to extra repayments and offsets. Fixed rates offer repayment certainty for a set period. Many investors end up with a split structure that combines both, to balance certainty with flexibility.
Offset accounts for tax efficient savings
An offset account lets you park surplus cash in an account linked to your loan. The balance in the offset reduces the interest you pay, while keeping the funds accessible.
This is useful for repairs, vacancy periods and future investment opportunities, without needing to redraw or change the loan each time.
This is the same principle that applies to owner-occupied loans, as outlined in our How to Pay Off Your Mortgage Faster guide, where small structural decisions can shave years off a loan and tens of thousands in interest.
Structuring your loans for long term wealth
Good loan structure is about more than just the interest rate. It affects your tax position, borrowing capacity and how easily you can take the next step in your strategy.
- Keeping your home loan and investment loans clearly separated.
- Avoiding unnecessary cross collateralisation that ties all your properties together with one lender.
- Using offset accounts instead of redraw when flexibility is important.
- Planning your lending around your next one to two properties, not just the purchase in front of you.
- Choosing lenders whose policies support your long term goals, such as portfolio growth or retirement planning.
A well structured lending setup can make the difference between being able to add another property in a few years, or being stuck because your borrowing capacity and cash flow have been stretched too far.
Using equity to buy your next investment
Many investors use equity from an existing property as the deposit for the next one. This can be done by refinancing, increasing the limit on a current loan, or setting up a new investment split secured by available equity.
Done correctly, this lets you move ahead without draining your savings. It also helps keep your records clean, so you and your accountant can clearly see which borrowings relate to investment and which relate to your home.
The key is making sure the structure is set up properly at the start, so the purpose of each loan split is clear and your future options remain open.
A practical guide to how it works and how to structure it correctly
A standalone loan structure keeps your owner-occupied and investment lending separate, allowing different lenders, greater refinancing flexibility, cleaner tax structuring, and more control over each property independently.
The Basics
What is Usable Equity?
Equity is the difference between what your property is worth today and what you owe on it. As your home's value grows and your loan balance reduces, your equity increases. Lenders generally allow you to access up to 80% of your property's current value — the amount above your existing loan balance is your usable equity.
For a $900,000 home with a $400,000 loan balance, the usable equity available is $320,000 — enough to fund the deposit and costs on a $640,000+ investment property.
Example calculation
Property value: $900,000
× 80% LVR = $720,000
Minus loan balance: $400,000
Usable equity: $320,000
Typically enough for a 20% deposit + purchase cost

How the Loan Structure Works
Your home acts as security for the equity release. The investment loan is kept completely separate — this is critical for tax purposes.
Process
How It Works — Step by Step
1
Property valuation
Your broker orders a bank valuation to confirm current equity
2
Calculate usable equity
Determine how much can safely be released at 80% LVR
3
Structure the loans
Equity release set up as a separate split — kept clean for tax
4
Secure pre-approval
Confirm borrowing capacity before making offers
5
Purchase the property
Equity funds the deposit; investment loan covers the balance
Considerations
Benefits and Risks to Understand
Benefits
- No need to save a cash deposit separately
- Faster entry into the property market
- Interest on investment loans is tax deductible
- Build wealth through capital growth and rental income
- Growing equity creates further investment opportunities
Risks to consider
- Total debt and repayments will increase
- If property values fall, equity position reduces
- Incorrect loan structuring can reduce tax effectiveness
- Cross-collateralisation limits flexibility at sale or refinance
- Rental vacancies can strain cash flow
Important — Loan Structure
The tax effectiveness of this strategy depends entirely on keeping your owner-occupied and investment loans clearly separated. Mixing the two loan purposes will create accounting problems that are difficult and costly to unwind. Always work with an experienced mortgage broker and your accountant before proceeding.
Common investor scenarios I help with
Every investor's situation is slightly different, but most fall into a few common patterns. Here are some of the ways I help clients structure their lending.
First time investor
Working out how much you can safely borrow, how your cash flow will look, and how to set up your first investment loan so it supports the next step in your plan.
Portfolio builder
Reviewing existing loans, freeing up equity, improving cash flow and selecting lenders that make it easier to add property number two, three or four over time.
Using property to support retirement
Restructuring loans to prepare for retirement, balancing income, debt reduction and equity so your properties work for your long term lifestyle needs.
Turning a home into an investment
Reworking your loans when you keep your current home as a rental and move into a new property, so the lending matches your new living and investment situation.
When it is worth reviewing your investment loans
A review can be helpful if:
- You are thinking about buying another investment property.
- Your interest rates or repayments have changed significantly.
- Your rental income has increased or you have added a new tenant.
- Your home loan is still high and you want a clearer strategy to reduce it.
- You are five to ten years from retirement and want to tidy up your structure.
- It has been more than two years since anyone looked closely at your loans.
The goal is not simply to chase the lowest rate. It is to make sure your lending is working in line with your broader financial and lifestyle goals.

Investment property FAQs
How much deposit do I need for an investment property?
This depends on the lender and your overall position, but many investors aim for 10 to 20 percent plus costs. In some cases equity from another property can be used instead of cash savings.
Should I choose interest only or principal and interest?
It comes back to your goals. Interest only can help with cash flow and growth, while principal and interest steadily reduces debt. We look at the numbers for your situation before deciding.
Can I use equity from my home to buy an investment?
Yes, this is common. The key is setting up the structure correctly so you can clearly see which borrowings relate to your home and which relate to your investment property.
Do all lenders assess rental income the same way?
No. Lenders use different shading rates and policies. Some will take a higher proportion of the rent into account, which can improve borrowing capacity. Part of my role is matching you with the right policy.
Can I build a portfolio on an average income?
Often yes, as long as the structure, property choices and cash flow are managed carefully. We look at your income, debts and goals, then map out what is realistic and sustainable.
Do you provide tax advice as well?
I do not provide tax advice, but I do work alongside your accountant so the lending structure supports the strategy they recommend for you.
Does the 2026 Budget affect my existing investment properties?
Properties you already owned on Budget night (12 May 2026) are grandfathered under the existing negative gearing rules.Properties owned on 12 May 2026 will be exempt, so existing investors won't be affected. However, the CGT changes apply to gains accruing from 1 July 2027 on all assets held by individuals and trusts, including existing properties.This means the negative gearing side is protected for existing holdings, but the CGT side affects everyone outside super when they eventually sell.
Are new build investment properties treated differently under the new rules?
Yes. The government will limit negative gearing to new builds from 1 July 2027, to focus tax support on new supply.Investors in new builds will be able to choose the 50% CGT discount or the new arrangements.This makes new builds comparatively more attractive from a tax perspective than established property purchased after Budget night.If you purchase land and construct the property the Stamp Duty is on the land value only, however, the hold costs need to be considered while under construction and there is no rental income.
Should I be looking at an SMSF after the Budget changes?
That is a question for your financial adviser, as SMSF structures involve complex legal and compliance considerations beyond lending.What I can tell you is that the Budget explicitly excludes properties held in superannuation funds from the new restrictions, meaning SMSFs can continue to fully deduct losses on both new and established residential properties.If your adviser recommends exploring an SMSF, I can help with the lending side — our SMSF property lending guide explains how that borrowing works.
Should I use a mortgage broker for an investment property loan?
Using a mortgage broker can help when buying or refinancing an investment property because the right loan structure can be just as important as the interest rate.A broker can compare lenders, assess borrowing capacity, review how rental income and existing debts may be treated, and help structure the loan around your wider investment goals.Mortgage brokers are usually paid by the lender once your loan settles. In most cases, you do not pay the broker directly for standard residential lending advice. Read more: How Do Mortgage Brokers Get Paid? →

How to accelerate your Investment Portfolio
Many investors assume the fastest way to build a portfolio is to purchase properties as quickly as possible. In reality, a more strategic approach is often to reduce the debt on your owner-occupied home first, thereby increasing usable equity and improving borrowing capacity for future investments.
By implementing a mortgage reduction strategy, homeowners can accelerate the reduction of their home loan balance and build equity sooner, which can then be accessed to fund deposits and costs for the next property purchase.
If you'd like to see how this works with real numbers, you can test the concept using the Mortgage Reduction Strategy Calculator.
Some investors encounter the HELOC vs. offset account strategy when researching ways to structure debt internationally.
