Investment Loans
The first investment loan is a lending question. The third is a structuring question. Here is what changes in between, and why it is worth setting up correctly from the start.
Structure Decides How Far a Portfolio Goes
Buying one investment property is mostly about servicing — can you afford it, and will a lender agree. Buying several is about something else entirely: whether each purchase leaves you able to make the next one.
That is decided by how the lending is structured, which lender holds which security, and how the equity is arranged. Those choices are cheap to make well at the start and expensive to unwind later.
- How rental income is treated — lenders shade it, and by differing amounts
- Whether properties are cross-collateralised or held separately
- Which lender sees which security, and in what order you approach them
- How existing investment debt is assessed when you apply for the next loan
- Whether the borrowing entity suits your circumstances
- Where the equity for the next deposit is going to come from

How Lenders Read Investment Income
Rental income counts, but not at face value. Lenders apply a discount to allow for vacancy, management fees and maintenance, and they do not all apply the same one. Two lenders assessing the same property can reach materially different conclusions about what you can borrow.
- Rental income is shaded before it counts toward servicing, at a proportion that varies between lenders.
- Existing investment debt is assessed at a buffer, often above the rate you actually pay — so a portfolio that is comfortably cash-flow positive can still assess as a constraint.
- Interest-only periods are commonly assessed on the remaining principal-and-interest term, which compresses the assessed repayment into fewer years and tightens servicing.
- Negative gearing benefits are treated cautiously, and some lenders do not add them back at all.
- Your own living expenses still apply, benchmarked and checked against statements, regardless of portfolio size.
This is why lender selection matters more on investment lending than on an owner-occupied loan. The difference between panels is not a rate decimal — it is whether the purchase is possible.
The Trap Worth Avoiding Early
When a lender takes two of your properties as security for one loan, the properties are cross-collateralised. It is convenient at the point of approval and constraining afterwards.
Selling one property then requires the lender’s agreement on what happens to the other. Releasing equity from one means the lender revalues both. Moving a single loan elsewhere can mean unwinding the whole arrangement. None of this is visible on the day you sign.
- Standalone security per property wherever it can be arranged
- Deposits funded by a separate equity release rather than a blended loan
- Spreading securities across lenders as a portfolio grows
- Keeping each property able to be sold or refinanced on its own
There are situations where cross-collateralising is the pragmatic choice. The point is that it should be a decision you made, not a default you inherited from whichever lender was easiest to approve.
Keep the Debt Clean
Interest is generally treated according to what the borrowed money was used for. Borrow to buy an income-producing property and the interest is generally deductible against that income; borrow for a private purpose and it is not.
The problem arises when the two are mixed in one balance — typically by redrawing against an investment loan for something personal. The loan becomes mixed, and apportioning it is awkward for as long as it exists. Our offset versus redraw guide covers the mechanism.
- Separate splits for each property rather than one blended balance
- Offset used in place of redraw where a purpose might later change
- Equity releases drawn as their own split, with the purpose documented
- Owner-occupied debt kept clearly apart from investment debt
Tax treatment is your accountant’s call. Our job is to build a structure that lets them give you a clean answer, rather than one that forces an apportionment argument years later.
The Process, Step by Step
- Portfolio positionWe map what you hold, what secures what, and where your usable equity and servicing capacity actually sit.
- Strategy and lender orderWhich lender to approach for this purchase, and which to preserve for the next one.
- Pre-approvalAn assessed pre-approval so you know your ceiling before you bid, not after.
- Purchase and applicationThe application is lodged with the structure already decided, not retrofitted after approval.
- Settlement and reviewSettlement, then a check on what the purchase did to your capacity for the next one.
What to have ready
- Payslips, or two years of returns and financials if self-employed
- Statements for all existing home and investment loans
- Rental statements or leases for properties you already hold
- Your most recent tax returns, including rental schedules
- Council rates notices for existing properties
- Photo identification
Not all of it is needed on day one. We will tell you what matters first so you are not gathering paperwork you do not need yet.
Common Questions
How much deposit do I need for an investment property?
It depends on the lender and whether you are contributing cash or releasing equity from a property you already own. Below a certain equity threshold, Lenders Mortgage Insurance generally applies, and on investment lending the thresholds can differ from owner-occupied. The more useful question is usually not the minimum, but what deposit leaves you able to buy again.
Can I use equity in my home as the deposit?
Frequently, yes — it is one of the more common ways investment purchases are funded. How much is usable depends on the valuation and on servicing the additional borrowing. It matters that the release is set up as its own split with the purpose documented, rather than blended into your home loan, because that is what keeps the debt clean.
Should my investment loan be interest-only?
It depends on your cash flow, your plans for the property and how it interacts with your other debt. Interest-only improves near-term cash flow and does not reduce the balance, and lenders commonly assess the repayment over the remaining principal-and-interest term, which can tighten servicing. It suits some strategies and not others — it is a decision to make deliberately with your accountant.
What is cross-collateralisation and should I avoid it?
It means one lender holds more than one of your properties as security for a loan. It can make an approval easier, but it ties the properties together — selling or refinancing one then involves the other. Wherever it can reasonably be arranged, we prefer standalone security so each property can be dealt with on its own.
How many investment properties can I finance?
There is no fixed number. What limits most portfolios is servicing capacity and how existing debt is assessed, rather than any cap on properties. Structure is what usually determines whether the constraint arrives at the second purchase or the fifth, which is why it is worth planning before the first.
Do investment loans cost more than owner-occupied loans?
Investment lending is generally priced and assessed differently from owner-occupied lending, and criteria vary between lenders. Because the differences are not uniform, comparing across a panel matters more here than on a straightforward home loan.
