Specialist Disability Accommodation produces income differently to a standard rental property, and that difference is the whole reason investors look at it. This article walks through the mechanics with a worked example, so you can see where the return actually comes from.
The Income Model in One Paragraph
An ordinary rental property earns one rent from one tenancy, set by what the local market will pay. An SDA dwelling earns payments tied to the NDIS participants living in it, under a funding framework designed to make purpose built accessible housing viable to deliver. Each eligible participant in the dwelling attracts a payment. A dwelling designed for more than one participant therefore has more than one income stream.
That is the structural difference. Everything else follows from it.
A Worked Example
Take a hypothetical dwelling in south east Victoria, built a couple of years ago for somewhere between $650,000 and $700,000. The figures below are illustrative and are used to show how the mechanics work, not to describe a specific property.
Say it is designed to house two participants under the Robust design category, and both places are filled. Assume for the example that each participant attracts around $75,000 a year. That is an assumed input rather than a quoted price limit, and the actual figure for any real dwelling comes from the current NDIS SDA price limits for its design category, build type, resident count and location. On those assumptions, the dwelling produces roughly $150,000 a year in total.
Against a build cost of $700,000, that is a gross return in the order of 21%. Even allowing generously for costs, it is a materially different number to what a standard residential dwelling at the same price produces.
Now Bring the Loan Into It
Income figures on their own do not tell you what you keep. The loan does most of the work in that calculation.
Continuing the example: an 80% loan on a $700,000 property means borrowing $560,000, with a $140,000 deposit. Interest on that borrowing might run in the order of $36,000 a year, depending on the rate.
Set that against $150,000 of income and the picture is stark. One participant’s payment covers the interest with room left over for running costs. The second participant’s payment is broadly what is left.
That framing is a useful way to think about multi participant SDA generally: the first income stream services the debt, and the additional stream is where the margin sits.
What the Example Does Not Include
Being honest about the gaps matters more than the headline number.
Costs. The example above deals with gross income and interest only. Real holding costs include property management, insurance, council rates, maintenance, and any specialist servicing or compliance costs attached to an SDA dwelling. On a dwelling producing $150,000, costs in the order of $20,000 to $35,000 a year are a reasonable starting point to model, and your own figures should replace that estimate.
Vacancy. The figures assume the dwelling is fully occupied. An SDA dwelling with an empty place is producing a fraction of its potential income, and filling SDA vacancies depends on participant demand and provider relationships in that specific location, not on general market demand.
Funding framework risk. SDA payments are set within a policy framework. Frameworks are reviewed and can change. That is a real risk and it should be part of how you assess the asset, not a footnote.
Tax. Nothing above accounts for tax, which will differ substantially between investors depending on structure and income.
Why Location and Design Category Drive the Number
Two SDA dwellings at the same purchase price can produce very different returns, because payment levels vary by design category and by location, and because occupancy depends entirely on whether there is participant demand where the dwelling sits.
This is why the site selection and design category decisions matter more in SDA than in standard residential. You are not buying into a broad market that will find you a tenant. You are buying a specific asset that suits a specific participant profile in a specific place.
The Takeaway
SDA yields can be strong, and the reason is structural rather than speculative: multiple funded income streams from a single dwelling, against a build cost set by construction rather than by market sentiment.
The return is also conditional. It depends on occupancy, on the design category, on where the dwelling is, and on a funding framework staying broadly stable. Those conditions are worth understanding before you buy, not after.
This is general information only and not financial, tax or legal advice. The figures used are a worked example, not a projection, and are not a reliable indicator of future performance. SDA returns depend on occupancy and on the applicable funding framework. Speak to a licensed adviser about your circumstances.
