What’s the essential difference between an off-the-plan apartment and an established townhouse?

An off-the-plan apartment is a property you buy before it’s built, based on architectural plans, a display suite and a contract of sale — settlement happens later, once construction and title registration are complete. An established townhouse already exists: you can walk through it, arrange an inspection, and settlement follows a standard timeframe after you exchange contracts. That’s the core split — buying a promise you can’t yet inspect, versus buying something you can see and touch right now.

Neither option is automatically the better investment. The right choice depends on your finance position, how much construction risk you’re comfortable carrying, your tax situation and what you want the property to do for you. This guide sets out the concrete differences — process, depreciation, land content, holding costs and current tax treatment — so you can weigh them against your own goals, rather than picking one because it sounds safer.

How does the buying process and inspection differ?

With an off-the-plan purchase, you sign a contract based on plans and specifications, often with a deposit held in trust, well before the building exists. Settlement is tied to construction completion and plan registration, so the date quoted at contract signing is an estimate — builds can run later than planned. Most off-the-plan contracts also include a sunset clause: a date by which the project must be completed and registered, with rescission rights that apply if it isn’t. The specific sunset date, and what happens if it’s triggered, is set out in your own contract — have a conveyancer or solicitor review it before you sign, not after.

Because there’s no finished building yet, you can’t get a standard building and pest inspection at contract stage. You’re relying on the plans, specifications and display suite instead, though most contracts give you an inspection opportunity at or before handover. New builds also typically come with statutory home warranty or builder defect protections — the specifics vary by state, so check them in your contract and with your state’s building regulator.

An established townhouse works the other way around. You, or your buyer’s agent, can inspect the actual property and arrange a building and pest inspection before you’re locked in, and settlement follows the standard timeframe in your contract of sale rather than a construction schedule. Cooling-off arrangements and standard contract terms also differ by state, so confirm the details with your conveyancer or your state’s fair trading or consumer affairs office.

How does depreciation differ between a new build and an established property?

Depreciation is one of the more concrete differences between buying new and buying established — and it’s genuinely shaped by tax law, not just preference.

Both a new off-the-plan apartment and an established townhouse can generally claim capital works deductions under Division 43 of the tax law: a deduction for the building’s construction cost, currently set at 2.5% a year over 40 years, for construction that commenced on or after 16 September 1987 (ATO’s capital works deductions guidance). An established townhouse built after that date may still have some of that 40-year claim left; a genuinely new off-the-plan build gets the full 40 years from completion.

Plant and equipment depreciation — Division 40, covering things like ovens, carpets and air-conditioners — is where the two diverge sharply. Since the Treasury Laws Amendment (Housing Tax Integrity) Act 2017, investors generally can’t claim Division 40 deductions for second-hand plant and equipment in a residential property — that is, assets that were already installed when you bought. Buying an established townhouse typically means buying second-hand fixtures and fittings, so this restriction usually applies. A genuinely new off-the-plan apartment, where nobody has lived in it before and the plant and equipment is new when you acquire it, generally isn’t caught by the second-hand restriction, so Division 40 deductions can still be available.

How this nets out for your own return depends on the specific property, its build-cost breakdown and your circumstances. Tax outcomes depend on your circumstances — speak with a registered tax agent before acting.

Does land content — and land tax exposure — differ between an apartment and a townhouse?

Generally, yes. An apartment sits on strata title, where your ownership includes a small, shared entitlement to the land under and around the building — the land component per unit is usually modest, split across every apartment in the block. A townhouse still commonly sits on strata or community title, but typically carries more direct land per dwelling than an apartment in the same building, simply because fewer dwellings are sharing the block.

That matters because land tax — a separate, ongoing state or territory tax on the value of land you own beyond your own home — is assessed on land value, not on the whole property. A bigger land share generally means a bigger land tax base, all else equal. Land tax is set by each state and territory individually, with its own threshold and its own scale — there’s no single national land tax, and thresholds move with state and territory budgets. The Northern Territory is the only jurisdiction that levies none at all — its own government states this directly: “There is no land tax in the NT”. Every other state and territory has its own current threshold: check directly with that state’s revenue office before you factor a figure into your numbers, since a rate that applied last financial year isn’t guaranteed to still apply.

Land tax outcomes also depend on your other land holdings in that state, not just the one property. Tax outcomes depend on your circumstances — speak with a registered tax agent before acting.

Are body corporate costs and rental yield calculated differently?

Almost every apartment comes with an ongoing body corporate (or owners corporation/strata) fee, covering building insurance, common-area upkeep and a capital works fund for bigger jobs like roof or lift repairs. A townhouse may or may not carry the same fee — it depends on whether the development is strata or community titled, or set up on a single title with no shared scheme. Where a body corporate fee applies, it’s one of the expenses the ATO’s rental properties guide lists as immediately deductible against rental income in the year you incur it, the same as council rates or building insurance.

Rental yield itself is calculated the same way regardless of property type. Gross rental yield is annual rent divided by the property’s value, multiplied by 100 — the definition the Reserve Bank of Australia itself uses; net yield subtracts your actual operating expenses, including any body corporate fee, before that same calculation (Defence Housing Australia). Whether an apartment or a townhouse produces a stronger yield for a specific listing depends on that listing’s price, rent and running costs, not on the property type in general. See our guide to calculating rental yield for the full formulas and the difference between yield on cost and a current yield.

How do you weigh vacancy risk and tenant demand without picking a suburb?

No article — including this one — can tell you which suburb, or which property type, will attract stronger tenant demand in future. What you can do is check the data yourself for any specific listing: ABS rental and vacancy data, your state planning department’s approvals and supply pipeline, and days-on-market figures for comparable listings nearby all give you a read on current conditions for that location, without anyone predicting where it’s headed.

Apartments and townhouses can suit different tenant profiles, and proximity to transport and lifestyle amenities matters for both — as does the supply of comparable listings nearby (a suburb with a lot of new apartment stock coming online is a different vacancy picture to one with very little). That’s a research question for the specific address, not a property-type rule. Our guide to researching a property market and suburb walks through the data sources and the method in more depth; for a specific decision, a licensed buyer’s agent or financial adviser can help you apply it.

Does capital gains tax treatment differ, now or after the 2027 reform?

Under current law, as at July 2026, an eligible Australian resident individual who holds a property for at least 12 months generally has access to the 50% CGT discount on any capital gain — and this applies the same way whether the property is a former off-the-plan apartment or an established townhouse (ATO’s CGT discount guidance). Current law doesn’t treat the two differently on this point.

That’s set to change. An enacted reform — the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, royal assent 26 June 2026 — ends the 50% discount for individuals, trusts and partnerships on capital gains from CGT events on or after 1 July 2027, with a carve-out retained for new residential dwellings and qualifying affordable housing. Exactly which properties will qualify as a “new residential dwelling” for that carve-out at the time of a future sale hasn’t been settled in ATO guidance as at July 2026, so this is genuinely open rather than something this guide can resolve for you. Tax outcomes depend on your circumstances — speak with a registered tax agent before acting, particularly if a future sale might fall on or after 1 July 2027.

What should you actually compare before deciding?

Rather than treating this as off-the-plan versus established in the abstract, it helps to lay the two out side by side for the actual property you’re considering.

Factor	Off-the-plan apartment	Established townhouse
Can you inspect it before you commit?	No — plans and display suite only	Yes — building and pest inspection available
Settlement timing	Tied to construction; can move	Standard timeframe after exchange
Contract risk	Sunset clause and construction risk apply	Standard contract and cooling-off terms
Division 40 (plant & equipment) depreciation	Often available (genuinely new)	Usually restricted (second-hand assets)
Division 43 (capital works) depreciation	Full 40 years from completion	Remaining balance, if built after 16 Sep 1987
Land component	Typically smaller, shared under strata	Typically larger, but often still strata/community titled
Body corporate fee	Almost always applies	Depends on title type

None of that adds up to a verdict — it’s the checklist to work through for the specific listing, your own finance and tax position, and how long you plan to hold. A licensed buyer’s agent can help assess a specific off-the-plan contract or established property against your goals, and a registered tax agent can confirm how the depreciation and CGT points apply to you.
