Investors regularly ask why a tenanted Specialist Disability Accommodation dwelling carries a higher price than the cost of building the same thing new. It looks like a premium for nothing. It is not.
The answer is that you are buying two different things. One is a construction project. The other is an income stream that already exists.
Two Ways to Price a Property
Build cost pricing is what you pay for a new dwelling. It reflects land, construction, compliance and delivery. It is a cost based number, and it comes with a period where the property earns nothing while it is being built and then filled.
Yield based pricing is what a tenanted asset is worth. Here the price is set by the income the dwelling already produces and the return a buyer expects on that income. It is a value based number.
Commercial property has worked this way for a long time. In our experience a tenanted SDA dwelling behaves more like a commercial asset than a residential one, because its value is anchored to a functioning income stream rather than to what comparable houses sold for down the road. Valuation practice in this market is still maturing, though, and not every valuer takes that approach. Some still price off residential comparable sales, which can produce a very different number for the same property.
How the Arithmetic Works
Take a dwelling built two or three years ago for around $700,000, now housing two participants. Assume for the example that it produces roughly $150,000 a year. The real figure for any dwelling comes from the current NDIS SDA price limits for its design category, build type, resident count and location.
A buyer looking at that asset is not asking what it cost to build. They are asking what return they get on what they pay.
- At $1 million, the income represents a 15% return.
- At $1.5 million, it represents 10%.
If comparable income producing assets are trading around a 10% yield, the tenanted dwelling logically prices somewhere near the upper figure, well above its original build cost.
That is not a markup. It is the same mechanism that prices every income producing asset: the market pays for the income, and the price adjusts until the yield matches what buyers require.
What the Premium Is Actually Buying You
It helps to be specific about what changes hands, because the premium is paying for real things.
Income from day one. A new build produces nothing during construction, and nothing between completion and the first tenancy. A tenanted dwelling starts paying immediately.
Removal of occupancy risk. In SDA, filling the dwelling is the hard part. Participants have to be found, matched to the dwelling and supported into it, and that depends on local demand and provider relationships. A fully occupied dwelling has already cleared that hurdle.
Proof rather than projection. With a new build, the income is a forecast. With a tenanted dwelling, it is a track record. You can see what the dwelling actually earns, with actual participants in it.
Certainty on delivery. No build timeline, no certification sequence, no construction risk. The asset exists.
Put together, that is a de risked version of the same investment. De risked assets cost more. That is true in every asset class.
The Case for Building New Instead
There is a genuine argument on the other side, and any honest article has to make it.
Building new means paying build cost rather than yield based value, which means your entry price is lower for the same physical asset. You get to specify the dwelling, choose the design category and select the location rather than accepting someone else’s decisions. You get a builder’s warranty and a brand new asset with a full depreciation runway. And under the 2026 tax reform, new build residential property retains negative gearing, where established dwellings purchased after 7:30pm AEST on 12 May 2026 can only deduct losses against other residential property income.
That tax difference is significant enough that it belongs in this comparison rather than as a footnote, and it may materially narrow the apparent advantage of buying tenanted.
Which One Suits You
The choice is a trade between price and certainty.
Buying tenanted suits investors who want income immediately, want to avoid occupancy and construction risk, and are prepared to pay for that certainty.
Building new suits investors who want the lower entry price, want to control the specification and location, and are prepared to carry the build period and the initial tenanting risk to get it.
Neither is the right answer in general. Both are the right answer for a particular buyer.
