Brisbane Houses vs Units: The Data Behind the Decision
PA
PropertyLens AI## The Saturday Morning Dilemma
It's 9:45am on a Saturday in New Farm. Two open homes, back to back. The first is a three-bedroom Queenslander on 405 sqm — $1.42 million, needs work, but the land is real. The second is a two-bedroom apartment in a boutique six-unit complex two streets away — $720,000, renovated, rooftop terrace, no maintenance headaches.
Both buyers leave with brochures and a headache. The numbers look close enough to make the decision genuinely hard. But when you dig into the data — historical growth rates, yields, holding costs, oversupply dynamics — the picture becomes considerably clearer. Not always in the direction you'd expect.
This article is for anyone wrestling with that exact choice. Let's go through the evidence properly.
## Capital Growth: The Long-Run Story
The headline fact first. Over the 20 years to 2025, Brisbane houses have outperformed units on capital growth — and it hasn't been particularly close.
Brisbane house medians have grown at roughly 6.8% per annum over the past two decades. Units have managed closer to 3.9% annually over the same period. That gap compounds brutally. A $500,000 house in 2005 would be worth approximately $1.87 million today at 6.8% compound growth. A $400,000 unit at 3.9% would have reached around $853,000.
The divergence is partly structural. Houses sit on land, and land in Brisbane's inner and middle rings has become genuinely scarce as the city has grown. Units, by contrast, can be built upward — and Brisbane has seen waves of unit construction that periodically flood the market with new supply, suppressing price growth for existing stock.
The post-2016 apartment oversupply is the clearest example. Between 2016 and 2019, Brisbane's inner-city unit market went backwards in nominal terms in many suburbs — Spring Hill, South Brisbane, Fortitude Valley — while houses in those same areas held their ground or grew modestly. Buyers who purchased off-the-plan units in that cycle are, in many cases, still underwater.
The 2022–2025 cycle has been more nuanced. The Olympic announcement, interstate migration, and constrained housing supply pushed both houses and units upward. But houses still led. Brisbane house medians crossed $900,000 in 2024 and are sitting around $970,000 in late 2025. Unit medians have moved from roughly $480,000 to around $590,000 over the same period — solid growth, but still trailing.
## Rental Yields: Where Units Win
Here is where the unit case gets stronger. Gross rental yields on Brisbane houses are currently running around 3.4% to 3.8% in the inner suburbs, and slightly higher — 4.0% to 4.5% — in the middle ring. Units, by contrast, are yielding 4.8% to 5.6% across much of inner Brisbane, with some well-located two-bedders in suburbs like Woolloongabba, Kangaroo Point, and Kelvin Grove pushing past 5.8%.
For an investor whose primary concern is cash flow — particularly one with a large mortgage — this yield gap matters enormously. On a $700,000 unit at 5.2% gross yield, you're collecting roughly $36,400 per year in rent. On a $1.1 million house at 3.6%, you're collecting around $39,600. The absolute dollar figure is higher for the house, but the house required $400,000 more capital to achieve it.
The catch, of course, is net yield. Once you subtract body corporate fees, strata insurance, management fees, and maintenance, the unit's yield advantage narrows. A body corporate levy in a mid-sized complex might run $4,000 to $8,000 per year. A well-maintained house might cost $3,000 to $5,000 annually in maintenance and insurance. The gap closes, but for most units in well-run buildings, a yield advantage of 0.8% to 1.2% over comparable houses survives on a net basis.
## The Body Corporate Reality
Body corporate costs deserve their own section because buyers consistently underestimate them — and because they vary so dramatically between buildings that they can make or break an investment.
A boutique six-unit complex in Paddington might have annual levies of $3,500 per lot. A 120-unit high-rise in South Brisbane with a pool, gym, concierge, and ageing infrastructure might charge $12,000 to $18,000 per year. That's not a rounding error — it's the difference between a positive and negative cash flow position.
The sinking fund is equally important. Bodies corporate are required to maintain a sinking fund for capital works, but many buildings — particularly those built during the 2010–2018 construction boom — have underfunded sinking funds relative to their maintenance obligations. When the roof needs replacing or the lift requires a full overhaul, lot owners face special levies. These can run from $5,000 to $30,000 per lot depending on the scale of the work.
Before buying any unit, request the last two years of body corporate financials, the most recent AGM minutes, and the independent sinking fund forecast. A building with a sinking fund deficit and ageing common property is a liability dressed as an asset.
## Maintenance and Lifestyle Trade-offs
This is where personal circumstances matter as much as the numbers.
A house gives you control. You decide when to paint, when to renovate, whether to add a deck or put in a pool. You don't need a committee's approval to install solar panels or change the front door colour. For owner-occupiers who want to personalise their home, this autonomy has real value.
But control comes with responsibility. Roofs, gutters, stumps, termites, hot water systems, fences — these are all your problem. For a busy professional, a retiree, or someone who travels frequently, the appeal of a well-run body corporate that handles building insurance and exterior maintenance is genuine and rational.
For investors, the calculus is slightly different. A house gives you more flexibility to add value — a granny flat, a renovation, a subdivision if the block allows — but requires more active management. A unit in a quality building largely runs itself, which suits investors who want a passive holding.
## Oversupply Risk: The Unit Market's Persistent Threat
This is the risk that unit buyers must understand before they commit.
Brisbane has a history of building too many apartments in response to demand signals, then watching prices stagnate or fall as supply overwhelms absorption. The 2013–2019 cycle is the textbook case. Developers responded to strong interstate migration and low rates by building aggressively in the CBD fringe. By 2017, vacancy rates in inner Brisbane hit 4.2% and unit values in suburbs like Newstead, South Brisbane, and Bowen Hills fell 10–15% from peak.
In late 2025, the risk profile is more mixed. Construction costs remain elevated — $3,800 to $4,500 per sqm for quality apartment construction — which has suppressed new supply. Development approvals are running well below the peaks of the mid-2010s. The Olympic pipeline is adding infrastructure but not necessarily apartments at the rate some feared.
However, the pipeline is not empty. South East Queensland's planning framework targets significant density along the inner-city transport corridors, and several large-scale projects in Bowen Hills, Woolloongabba, and Northgate are in various stages of approval. Buyers purchasing units in these high-supply corridors need to model what happens to their resale value when 300 new apartments hit the market two suburbs over.
## Which Unit Types Actually Perform
Not all units are created equal, and the data makes this clear.
**Boutique complexes outperform high-rises.** Buildings with fewer than 20 lots consistently show stronger capital growth than large towers. The reasons are partly supply (there are fewer of them) and partly quality (boutique buildings in Brisbane are more often conversions of older character stock or architect-designed projects with genuine scarcity value).
**Two-bedroom units outperform one-bedders.** One-bedroom apartments have the weakest long-run growth profile of any residential property type in Brisbane. They attract a narrow buyer pool — mostly investors and singles — and in a downturn, they're the first to see vacancy rise and values fall. Two-bedroom units with a car space, storage, and a functional layout have a far broader resale market.
**Older buildings in good suburbs outperform new towers in fringe locations.** A 1980s brick unit in Ascot or Clayfield, well maintained with a functional floor plan, will hold its value better than a 2018 off-the-plan apartment in Bowen Hills. The land-to-asset ratio is higher in the older building, the body corporate is typically more experienced, and the suburb itself has a proven demand base.
**Ground-floor units underperform.** Privacy, noise, and security concerns make ground-floor units consistently harder to sell and rent. If you're buying a unit as an investment, floors two through four in a low-rise building are the sweet spot — high enough for privacy, low enough to avoid lift dependency.
## How to Avoid Buying into a Building That Will Lose Value
There are specific warning signs that experienced buyers look for.
- **High investor concentration**: If more than 50–60% of lots are investor-owned, the building is vulnerable to a wave of simultaneous selling in a downturn. Owner-occupiers stabilise buildings.
- **Short-term rental saturation**: Buildings with heavy Airbnb usage often have deteriorating common property, fractious body corporates, and reduced appeal to long-term tenants and buyers.
- **Defect history**: Post-2010 construction in Queensland has a documented defect problem. Buildings constructed between 2010 and 2020 should be scrutinised carefully. Check QBCC records for any rectification orders or complaints against the developer or builder.
- **Underfunded sinking funds**: As noted above, this is a direct financial liability. The sinking fund forecast report will tell you whether the building is on track or facing a shortfall.
- **Strata title vs. community title schemes**: Community title schemes with sub-schemes (common in large master-planned developments) add layers of levies and complexity. Understand exactly what you're paying for.
## The Land Content Argument
Property investors often talk about "land content" as the primary driver of long-run growth. The argument is straightforward: land appreciates, buildings depreciate. A house on 600 sqm in Coorparoo has a higher proportion of its value tied to land than a unit in a 200-lot tower in the CBD. Over time, the land component drives the growth.
This is broadly supported by the data, but it's not an absolute rule. A well-located unit in a small complex — where the land-to-unit ratio is relatively high — can and does appreciate strongly. The New Farm two-bedder in a six-pack from the 1960s has outperformed many houses in outer Brisbane over the past decade, simply because of where it sits.
Location still beats asset class. A unit in Teneriffe will outperform a house in Deception Bay over most time horizons. The question is whether, within your target location, a house or a unit gives you better value for the capital you're deploying.
## Running the Numbers for Your Situation
The honest answer to "house or unit?" is that it depends on four things: your capital, your income, your investment horizon, and your lifestyle needs.
If you have $700,000 to spend and a 10-year horizon, a quality two-bedroom unit in a boutique building in an inner suburb will likely outperform a house at the same price point in a middle-ring suburb — because the inner suburb's location premium will compound more reliably than the middle-ring land value.
If you have $1.2 million and can stretch to a house in a suburb within 8km of the CBD, the land content argument starts working in your favour, particularly with Brisbane's Olympic-driven infrastructure spend improving accessibility across the inner ring.
If you're an investor prioritising cash flow, a well-chosen unit in a low-levy building will likely generate better net returns in the short to medium term, even if the capital growth trails a house over 20 years.
The worst outcome — and it happens more often than it should — is buying a unit in a large, high-supply corridor building because it looks affordable, without understanding the body corporate costs, the defect risk, or the competition from new supply. That's not a property decision. It's a hope.
## Using Data to Make a Better Call
The decision between a house and a unit is ultimately a data problem. You need suburb-level growth histories, comparable sales, rental yield data, body corporate financials, and an honest assessment of supply risk in your target area.
PropertyLens tracks suburb performance, median price trends, and rental yields across inner Brisbane, and its deep research reports can pull together comparable sales data and planning information for specific properties you're considering. If you're weighing up a unit purchase in particular, the planning constraints tool will show you what's approved or proposed nearby — which is exactly the kind of supply intelligence that can save you from buying into the wrong building at the wrong time.
The data is there. The decision is yours.
