How to Track an Investment Property Portfolio in Australia (2026 Guide)

By Mitchell Shad  ·  13 October 2026  ·  7 min read

Most property investors can tell you what their properties are worth. Far fewer can say what the portfolio costs them each week, how much equity they could actually access, or what happens to their cash-flow if rates rise. This guide covers what to track for an Australian investment property portfolio, how often to update it, and whether a spreadsheet or a dedicated tracker is the better tool.

Why property portfolios get messy

Property is the largest asset most Australian investors own, and it is also the hardest to keep a clear picture of. Each property has its own loan (often more than one), its own rent, its own costs, and sometimes its own owner: you, a joint account, a family trust, a company or an SMSF. The numbers sit in lender apps, property manager statements, council and water notices, and insurance renewals. Nothing pulls them together by default.

What to track for each property

For every property, record these:

• Estimated value and the date you set it. Use a recent valuation, a comparable sale or an online estimate, and note which. It is an estimate, so update it on a schedule rather than daily.
• Each loan against it: balance, interest rate, whether it is fixed or variable, interest-only or principal and interest, the lender, and the fixed-rate expiry date.
• Offset account balances linked to the loan. An offset reduces the interest you pay, so it belongs next to the loan it works against.
• Rent: weekly rent, and any vacancy allowance.
• Holding costs: loan repayments, council rates, water, insurance, strata or body corporate, property management fees, and a maintenance allowance.
• Purchase price and date, plus stamp duty and purchase costs, for capital gains records later.

The numbers worth calculating

From those inputs you can work out the figures that actually answer "how is this property doing?"

Equity is value minus the debt secured against the property.

LVR (loan-to-value ratio) is debt divided by value. A $600,000 loan on a $1,000,000 property is a 60% LVR. Lenders look closely at LVR when you borrow again, and the 80% line is the one most people watch.

Usable equity is the equity a lender would typically let you access, commonly 80% of the value less the debt. In the example above, 80% of $1,000,000 is $800,000, less the $600,000 loan, leaves $200,000 usable. This is the number that tells you whether a deposit for your next purchase already exists. Our guide to net worth vs usable equity explains why the two numbers can look so different.

Gross yield is annual rent divided by value. It is a quick comparison across properties, but it ignores costs.

Weekly cash-flow is rent minus every holding cost, including loan interest and repayments. This is the true weekly out-of-pocket (or surplus) for each property, and it is the number most people have never actually added up. Work it out before tax, and then after tax if you want the full picture, remembering that the tax effect depends on your own situation and is a question for your accountant.

Stress-test your portfolio

A snapshot tells you where you are. A stress test tells you how much room you have. Re-run your cash-flow with:

• Interest rates 1 to 2 percentage points higher, especially on loans coming off a fixed rate.
• Rent 10% lower, or a few weeks of vacancy each year.
• A large unexpected repair.

If the portfolio only works when nothing goes wrong, you want to know that now. This is also the exercise a lender runs on you, so doing it first puts you ahead of the conversation.

How often to update

• Loan balances and rates: monthly, or whenever a rate changes.
• Property values: every six to twelve months, or when comparable sales move noticeably.
• Rent and costs: whenever a lease renews or a cost changes, and a full review once a year before tax time.

Across entities

Many investors hold property in more than one structure. Track each property under the entity that owns it (personal, joint, trust, company or SMSF), then roll the entities up for your total position. Doing it this way keeps your tax records lined up with the right owner and still lets you see the whole portfolio at once. Our rental property tax deductions guide and investor tax return checklist list the records to keep for each property.

Spreadsheet or a property tracker?

A spreadsheet is free and fully flexible, and for one or two properties it is a reasonable start. The costs show up over time: you maintain every formula yourself, you re-enter loan balances and values by hand, a typo in one cell quietly changes your cash-flow, and it does not show how your property sits alongside your super, shares and cash.

A dedicated property portfolio tracker keeps each property's loans, equity and cash-flow on one card, calculates LVR and usable equity for you, and lets you test scenarios without rebuilding the sheet. The better ones also put property in context with the rest of your wealth, which matters because property is rarely your only asset. That is the idea behind a net worth tracker: see property, super, shares and cash together, and see how it all feeds the age you could stop working.

Compound is built for this. Each investment property gets its loans, usable equity, itemised weekly cash-flow before and after tax, yield, a stress test and a year-by-year forecast, and you can download a one-page summary for your mortgage broker. It sits next to your super, shares and other assets so property is never viewed in isolation.

Where to go next

• Work out your total position first with how to track your net worth in Australia.
• See how property fits into how much you need to retire.
• Check how much you could borrow next with borrowing power.
