NDIS housing: why SDA is not an investment to make lightly

Specialist Disability Accommodation (SDA) has become a prominent National Disability Insurance Scheme (NDIS) housing option. For people with disability, SDA is widely recognised as the leading housing model that promotes independence, autonomy and genuine choice and control.

According to the latest Australian Competition and Consumer Commission (ACCC) NDIS report, more than 750,000 Australians have NDIS funding and interest in SDA has surged.

The growth of the scheme has fuelled concerns from both government and sector advocates about risky and exploitative marketing practices in the SDA market, which frame this type of investment as a ‘cash cow’ opportunity promoting government-backed returns.

The ACCC NDIS Report highlights these issues impacting the market, which have had a detrimental impact on people with disability and retail investors, namely:

• misleading investment advertising: highlighting unrealistic investment returns and using false NDIS-backed guarantees
• risk of investment failure: If an unprepared investor suffers financial loss and needs to withdraw the property from the market.

For “mum and dad” retail investors or even experienced property developers, jumping into this market without due diligence and research holds risk for all involved.

Not all supply meets real demand

One of the biggest misconceptions about SDA is that any property built to any SDA Design Standard will automatically attract tenants. In reality, many factors influence whether a dwelling aligns with what potential tenants are looking for.

The ABC’s Four Corners investigation into NDIS-funded housing confirmed:

• mismatches between SDA supply and the actual NDIS participant demand
• properties are being built in more affordable and undesirable suburbs because they are far from existing supports, activities and services
• SDA places being built to inappropriate design categories
• vacancies in overbuilt regions, despite NDIS participants still waiting for suitable homes.

Areas where SDA has been marketed aggressively as a high‑yield investment often experience significant oversupply, leaving investors with properties that cannot be filled and needing to be repurposed into the mainstream market with significantly lower yields. Meanwhile, participants miss out on and are forced to wait for homes they actually want and need.

This is why it’s essential to work with trusted SDA and disability housing specialists who understand the market data, NDIS supports, legislation, and real participant preferences.

A challenging market with big requirements

All investment carries risk, but SDA investment brings additional complexities, especially for first‑time or small‑scale investors. These properties are not standard real estate assets. They involve specialised design, strict construction compliance, and ongoing operational considerations.

Key challenges include:

• Complex and evolving regulation: NDIS housing rules are detailed and frequently updated.
• Tightening SDA funding approvals: fewer participants are receiving SDA funding due to stricter evidence requirements.
• Longer approval timelines: backlogs in NDIS assessments can delay tenancy.
• Diverse tenant needs: participants will not choose a home simply because it is available. SDA tenants who live together in a shared house need to be a good match as housemates, and, secondly, their funding for both housing and support needs to be compatible.
• Dependence on service partnerships: supported Independent Living (SIL) providers, support coordinators, and planners all influence the success of a dwelling.

Without a strong understanding of these factors, investors risk entering a market that is far less stable than it appears. When SDA was introduced, it was expected to attract institutional investors.

Key considerations before investing in SDA

If you are evaluating an SDA investment, these are the non‑negotiable elements to research thoroughly.

1. Supply and demand data

Look beyond simple vacancy rates. Detailed data is needed to understand:

• the types of SDA currently available
• what is actually needed by people in the area
• the number of NDIS participants with SDA funding or likely to receive it, compared to the number of SDA places already available in a given location.

A mismatch between what is needed and what is offered, particularly in relation to location, who people can live with, and the model of support, drives long-term SDA vacancies.

2. Area suitability

For SDA tenants, location isn’t just about liveability, it’s about functionality and accessibility.

Consider:

• proximity to transport and shops
• medical services and allied health
• community engagement opportunities
• support worker availability
• infrastructure accessibility
• connection to family, friends, work and key services.

SDA cannot function in isolation; it must be built within the broader disability support ecosystem.

3. Funding landscape and NDIS trends

The NDIS is shifting and constantly reforming to reduce the scheme’s overall costs. SDA and support funding approvals typically take extended periods to be granted and to appear in NDIS plans.

The NDIS Quarterly Reports show that in the December 2024 quarter, there were 24,522 NDIS participants with SDA funding. The latest report (December 2025) shows that 25,502 participants have SDA funding. The number of people with SDA funding approved (demand for SDA) therefore increased by 980 people (or 4%) over the past 12 months.

In 2023, the NDIA released a report forecasting demand for SDA. It was reported that the number of NDIS participants in Australia expected to need a place in an SDA dwelling would reach 27,002 next year. If these forecasts were accurate and hold true, that suggests that around a further 1,500 people may become eligible for SDA over the coming year.

Be wary of claims of there being significant demand for SDA properties. The data released by the NDIA tells a different story. 

Relying on assumptions about future SDA growth without understanding these dynamics puts investments at significant risk.

Proceed with care and consideration

SDA developments play a vital role in improving housing options for Australians with disability, but they require thoughtful, data-driven planning and strong partnerships that place the future customer’s needs at the centre of the design, delivery and operations. The benefits for tenants can be life-changing, but for investors, the sector is far from a guaranteed financial success story.

If investment decisions are driven by hype or the promise of high returns without understanding the underlying market realities, the result can be costly vacancies, unmet tenant needs and long-term financial strain.

When SDA investment is approached with rigorous due diligence, accurate data and collaboration with sector experts, it can contribute to stronger housing outcomes and a more sustainable disability housing ecosystem.
