What should you check before buying an SDA property?

Short answer
Before buying an SDA property, check whether the dwelling is already enrolled with the NDIA, what design category and building type it's enrolled for, who will manage it, and whether a tenancy and service agreement are in place. Income from SDA is never guaranteed, so factor that risk in too.
Buying a property that's built or enrolled as Specialist Disability Accommodation (SDA) is different to a standard rental purchase. You're buying into a system the NDIA funds on a per-participant basis, not a guaranteed income stream. In our experience, the investors who do well are the ones who check the fundamentals before they sign a contract, not after. This guide walks through what to look at. For a broader look at returns and risk, see is SDA a good investment and SDA investment in South Australia.
Is the dwelling already enrolled?
A property isn't SDA just because it was built to the SDA Design Standard. A dwelling is not SDA until it is enrolled by the NDIA. If you're buying an existing SDA property, ask the seller or agent for the enrolment details and confirm them with the managing provider.
If you're buying a new build that hasn't been enrolled yet, check that it has been through SDA design standard certification, since all enrolment applications for newly built SDA must have this certification before the NDIA will consider enrolling it. An SDA provider can't claim payments for support they provide to a participant in a dwelling if the dwelling is not enrolled as SDA, so an unenrolled property earns nothing until that step is done.
Check the design category and building type
There are 4 types of building that can be an SDA home: apartment, villa, duplex or townhouse, house for up to 3 people, and group home for 4 or 5 people.
Ask which category and building type the property is enrolled for, or is being built for, and whether that matches demand in the area you're buying in. In our experience, a mismatch between what's built and what local participants need is one of the more common reasons a property sits vacant longer than expected.
Confirm who will hold the SDA registration
As an SDA investor, you must either be an SDA registered provider or enter into an agreement with an SDA registered provider. SDA providers must be registered through the NDIS Quality and Safeguards Commission with the SDA registration group approved, and they need to maintain that registration to keep providing SDA supports.
If you don't plan to become a registered provider yourself, find out early who will hold that registration and manage the dwelling. The NDIA is not involved with day-to-day management of SDA dwellings, so that responsibility sits with you and whoever you engage, not with the agency.
Understand that the income isn't guaranteed
Funding for SDA applies to the participant's NDIS plan, not the dwelling, so it can't be guaranteed. Income from an SDA dwelling is not guaranteed, as the property may be unoccupied or partially occupied for periods of time.
Ask about vacancy history for the property or similar properties nearby, how long it typically takes to find a resident in that area, and what the managing provider does to search for a new resident when a room becomes available. Build your numbers around a realistic occupancy rate, not a full one.
Check the tenancy and service agreements
Tenancy agreements must meet the requirements of relevant state and territory tenancy legislation. In South Australia, some disability accommodation arrangements sit outside the Residential Tenancies Act 1995 altogether: agreements aren't covered by the Act where the premises are used as a home for aged care or people with disability by an eligible organisation. Ask the seller or managing provider which arrangement applies to this property, and ask to see a copy of any existing tenancy agreement or service agreement.
Certain day-to-day living costs, including rent, are not an NDIS support that can be funded through the NDIS, which is why residents pay a rent contribution separately from their SDA funding. Write down any questions you have about how that contribution is collected and ask the managing provider directly.
Common questions
Can I buy an SDA property that isn't enrolled yet?
Yes, but it won't earn SDA income until it's enrolled. A dwelling is not SDA until it is enrolled by the NDIA, and for a new build that means getting SDA design standard certification first.
Do I need to be a registered SDA provider to own an SDA property?
No. As an SDA investor, you must either be an SDA registered provider or enter into an agreement with an SDA registered provider who manages the dwelling and claims payments on your behalf.
Is SDA income guaranteed once the property is enrolled?
No. Income from an SDA dwelling is not guaranteed, as the property may be unoccupied or partially occupied for periods of time, and funding follows the participant's plan rather than the dwelling.
What should I ask about the building type before buying?
Ask which of the four building types applies: apartment, villa, duplex or townhouse, house, or group home.
Who manages the property day to day after I buy it?
The NDIA is not involved with day-to-day management of SDA dwellings. That's handled by the registered provider managing the property, so it's worth confirming who that will be before you buy.
