According to the
realestate.com.au report on a derelict rural Victorian home that sold for just $110,000 despite being too dangerous to enter, even the most run-down investment properties carry a tax profile worth understanding before settlement. Buyers of cheap, older stock — and investors at every price point — routinely leave money on the table by failing to distinguish between the two categories of property depreciation the Australian Taxation Office recognises: Division 40 and Division 43. Getting this distinction right can materially change an investor's annual taxable rental position.
Two Very Different Depreciation Regimes
Why the Rules Changed and What It Means in Practice
Investors should be aware that the rules governing Division 40 and Division 43 claims have not always worked the way they do today, and that eligibility now turns heavily on timing and ownership history rather than simply on what exists within the property. A quantity surveyor preparing a schedule today must apply the current rules, which treat plant and equipment differently depending on when it was acquired and by whom.
The core distinction every investor needs to internalise is simple: Division 40 depends heavily on when you bought and what you install yourself, while Division 43 depends on when the building was actually constructed — and that construction date, not the purchase date, is what determines eligibility.

In practice, this means two investors who buy an identical property on the same day can end up with very different depreciation outcomes depending on what they do next. An investor who buys a second-hand unit and leaves the existing carpets, blinds, and appliances untouched generally cannot claim depreciation on those inherited items. An investor who strips out the old kitchen appliances and installs new ones after settlement can begin claiming Division 40 on those newly purchased assets from the date of installation, because they are now the first owner of that specific asset.
This creates a practical incentive for investors to consider staged renovations as part of their acquisition strategy, not purely for rental appeal but for the depreciation runway it opens up. A full kitchen or bathroom renovation, properly documented with invoices and installation dates, can generate a meaningful new Division 40 schedule even on an older established home.
Where Strata and Common Property Fit In
Investors who buy into apartment blocks or strata schemes face an additional layer of complexity, because common property assets — lifts, shared plant rooms, communal hot water systems, and building-wide fixtures — are typically depreciated at the body corporate level rather than by the individual unit owner. A unit owner's share of these common property deductions is usually passed through via the owners corporation's accounts and reflected in the unit holder's own tax return as a proportional entitlement. Understanding how body corporate levies, capital works funds, and common property depreciation interact is essential for any apartment investor trying to build an accurate full-property deduction picture; see our complete guide to body corporate and strata in Australia for how these shared costs and capital works funds are structured.
For an investor evaluating a strata property purchase, requesting the body corporate's most recent depreciation schedule and capital works fund statement before settlement is a practical due diligence step that can reveal whether meaningful deductions are already locked in, or whether a fresh quantity surveyor report will be needed after purchase.
Practical Steps for Investors
The starting point for any investor serious about maximising legitimate deductions is commissioning a formal depreciation schedule from a qualified quantity surveyor rather than attempting to self-assess construction costs or asset values. These schedules typically split the property into its Division 40 and Division 43 components, project the deductions over each asset's effective life, and provide the documentation an accountant needs to support claims if the ATO ever reviews the return.
Investors should also keep in mind that wider macroeconomic settings shape the environment in which these deductions matter. With the RBA holding its cash rate at 4.60% and inflation sitting at 2.4%, holding costs on investment debt remain a live consideration, which makes every legitimate deduction more valuable to an investor's cash flow position.
Finally, investors should treat depreciation planning as an ongoing exercise rather than a one-off task completed at purchase. Renovations, body corporate capital works, and asset replacements all change the schedule over time, and failing to update it means missing deductions an investor is legally entitled to claim. For the full breakdown of how these rules interact with capital gains tax, land tax, and other investor obligations, see our Australian Property Tax Guide, and for a deeper technical walkthrough of how schedules are built, see our guide to property depreciation schedules.
Whether an investor has just paid $110,000 for a derelict rural block or several million for a city apartment, the same principle applies: depreciation entitlements are determined by construction date, ownership history, and what is actually installed after settlement — not by purchase price alone. Getting professional advice before and after settlement, and keeping a current depreciation schedule, remains the most reliable way to ensure no legitimate deduction is left unclaimed.
