Investment property mortgage brokers now facilitate 81% of all new home loans written in Australia, the highest share ever recorded. For property investors, that raises a fair question. If almost everyone is using a broker, how do you pick one who’s actually good at investment lending? You wouldn’t want just any broker who happens to be available.
No two mortgage brokers are the same.
An investment property mortgage broker does more than just get a single owner-occupier loan approved. The job also involves understanding servicing calculations across multiple properties, assessing rental income, and understanding portfolio structure. Below, we’ve set out how to choose the right one, plus a heads-up on a trap that catches even experienced investors.
Quick Answer
- Look for a broker with a proven track record in investment lending. Try to steer clear of generalists handling their first portfolio client.
- Ask upfront how they’re paid and whether that changes across lenders or loan types.
- Panel breadth matters more for investors, since lender policies on rental income and multiple properties vary widely.
- A good broker will sometimes tell you to slow down and space out purchases, not just push the next approval through.
- SMSF property lending changed materially on 10 August 2026. If that’s part of your plan, get current advice before assuming the old rules still apply.
How to Choose the Right Investment Property Mortgage Broker
Most guides to investment lending jump straight into gearing and equity. But the first crucial step to protect yourself is choosing the right broker. Here’s what to check.
Relevant Experience
Investment lending isn’t the same skill as a standard home loan. Ask how many investment or portfolio clients your broker has worked with. Find out whether they’ve handled scenarios like yours, whether that’s a second property, a construction build, or a purchase through an SMSF.
Commission Transparency
Every broker is paid a commission by the lender, and a good one will tell you exactly how much, up front, without you having to ask twice. If a broker seems reluctant to explain their pay structure, that’s worth noting.
Panel Breadth
Investment lending policy varies enormously between lenders: how they assess rental income, how many properties they’ll lend against, and how they treat existing debt. A broker with a narrow panel can only show you a narrow slice of what’s available.
Communication
Portfolio building isn’t a single transaction. You want a broker who stays in the loop as your circumstances change, not one who disappears after the first settlement. Ask what ongoing contact looks like before you commit.
What a Broker Does for Your Investment Loan
Once you’ve picked the right broker, the day-to-day mechanics matter. Your broker can help you use equity in an existing property as a deposit. They can structure your loan around gearing and cash flow, and manage serviceability walls and cross-collateralisation risk as your portfolio grows. Our guide on investment property mortgage brokers walks through each of these in detail, including how lenders assess rental income and LVR limits.
More broadly, if you’re new to brokers altogether, our guide to what mortgage brokers do covers the basics of the relationship. It runs from the first conversation through to settlement.
Why Pacing Your Purchases Matters
This is the part almost nobody talks about. Buying several investment properties in quick succession can work against you, even if you can technically afford each one.
Lenders reassess your full financial position with every new application, not just the one in front of them. Each mortgage adds to your existing debt. Most lenders apply a serviceability buffer of about 3% above the actual rate when calculating whether you can service all your combined lending. Rental income only partially offsets this, since lenders typically “shade” it down to account for vacancies and costs.
Buy three properties inside twelve months, and you can hit a serviceability wall before you’ve had a chance to let rental income or capital growth improve your position. An investment property mortgage broker who understands pacing will sometimes recommend a gap between purchases.
This gives valuations time to catch up and your servicing capacity room to reset, rather than rushing you into the next deal. It’s a less exciting recommendation for those eager to invest fast, but it’s often the one that protects your future portfolio and purchasing power.
Where SMSF and Construction Lending Fit In
Not every investor is buying an established property with a standard loan. If part of your strategy involves superannuation or a new build, there are separate rules to understand.
Buying through your SMSF
This area changed significantly on 10 August 2026. New Limited Recourse Borrowing Arrangements can generally only be used to acquire business real property from that date onward. Existing SMSF residential property loans are grandfathered and can still be refinanced, but new SMSF borrowing for residential property is no longer available in most cases. The ATO’s guidance on the changes sets out the details.
If SMSF property was part of your plan, talk to our SMSF mortgage broker team and your accountant to check what pathways are open.
Building rather than buying
If your investment strategy involves a new build, knockdown-rebuild, or land purchase, construction lending works differently to a standard investment loan, with staged drawdowns and different servicing assessments.
Construction loan brokers are helpful resources and could provide information on how this fits into an investment strategy.

FAQs
Can I use equity as a deposit for an investment property?
Yes, this is one of the most common ways investors fund a purchase. If your existing property has grown in value, you may be able to access a portion of that equity through a refinance and use it as a deposit. That means not needing to save one from scratch. How much you can access depends on your current loan, the property’s valuation, and the lender’s LVR limits.
Do brokers charge more for investment loans?
Generally, no. Brokers are paid a commission by the lender in the same way for investment and owner-occupier loans, so in most cases there’s no direct cost to you either way. Some complex investment scenarios, such as SMSF lending or unusual security structures, can involve a fee, and a good broker will always disclose this before doing any work.
How many investment properties can I realistically buy at once?
There’s no fixed number. It depends on your income, existing debt, deposit or equity position, and how lenders assess your combined serviceability. This is exactly why pacing matters. A broker who works in investment lending regularly can help you sequence purchases sensibly, rather than maxing out your borrowing capacity in one run.
Should I use one lender for multiple investment properties?
Not necessarily, and in some cases it’s worth avoiding. Using the same lender for multiple properties can lead to cross-collateralisation, where one lender holds security over several properties at once. This can limit your flexibility later. Structuring lending to keep your properties as independent as possible, where that suits your strategy, is something worth raising directly with your broker.
