Most commercial property value add stories involve a builder. This one didn't. In February 2022 my two partners and I bought a fully leased office warehouse at Dry Creek in Adelaide's inner north for $3,850,000. In December 2023 we sold it for $4,750,000, before a development application was even lodged. No slab was poured. No builder was engaged. The value was manufactured on paper, and the existing tenant paid the holding costs while we did the work.
I'm writing this one up because it's the clearest example I have of the gap between what a commercial listing tells you and what the asset actually is. It's also my own money, my own deal, which means I can show you the workings without a client's privacy in the way.
The listing said yield. The land said something else.
The property came to market as an income play: 982 square metres of office warehouse, fully leased to a subsidiary of a global brand, returning $154,500 net.
On the purchase price, that passing income worked out at roughly 4% net. For an Adelaide industrial asset in 2022, that is not a yield anybody should get excited about. If you graded the deal purely on income, you'd walk.
But income is only half of what I grade. Under The Deal Grade, the building gets a letter from A to C on the physical asset and the income gets a number from 1 to 3 on the lease. The income here graded well enough to do one job and one job only: carry the holding costs while we worked. It wasn't the asset. It was the funding.
The asset was underneath it. That 982 square metre building sat on 8,928 square metres of Strategic Employment land. That's 11% site coverage, with dual access and 121 metres of frontage.
Eleven percent. Nine tenths of what we were buying was open ground in a zone that permits exactly the kind of development the market was short of.
Why site coverage is the number I check before the yield
On an industrial or commercial landholding, site coverage tells you how much of the asset is already spoken for. A tightly built site at 60% or 70% coverage is what the listing says it is: a building, an income, a yield. There is no third act.
A site at 11% coverage is a landholding with a rent cheque attached. What matters then is not the current income, it's what the zone allows, what the access and frontage support, and whether the market wants that space.
The Adelaide numbers have kept saying yes on that last point. JLL's Q1 2026 research put industrial land value growth at 17.4% year on year for quarter-hectare lots, reaching around $1,056 per square metre, and 22.6% for 1.6 hectare lots at around $728 per square metre. CBRE had Adelaide's industrial vacancy at 2.0% in its Q1 2026 figures, and the 2026 to 2028 development pipeline was running above the ten-year average with roughly two thirds of it already pre-committed. Knight Frank reported $404 million in Adelaide industrial investment sales in the first half of 2026 alone.
None of that is a prediction, and none of it was knowable in February 2022. What was knowable was the structural setup: constrained land, deep occupier demand, and a zone that let us build.
The third value lever, at full scale
On every commercial appraisal I run, I quantify three value levers the selling agent won't model for you, because they work for the other side.
Covenant upgrade. Same rent, stronger tenant, tighter cap rate. The signature on the lease can be worth more than the building works.
Reversion capture. Buy under-rented, reset at expiry. You pay for today's lease and keep tomorrow's upside.
Lettable area. Mezzanines, expansions, and in the biggest version of the play, new buildings on land you already own. The cheapest floor space you'll ever buy is the air above your own site.
Dry Creek was the third lever taken as far as it goes. We masterplanned 13 office warehouses ranging from 208 to 1,033 square metres, with eight metre clearance. We commissioned the 3D designs. We named it TenSixteen Business Park and gave it an identity a tenant or a developer could picture. Then we took the whole project to market.
In December 2023 a buyer took the lot: the site, the plans, the brand, the positioning. $4,750,000. The DA had not been lodged.
$900,000 across 22 months, and the only physical thing that changed on the site was nothing at all.
What actually created the value
It wasn't luck and it wasn't the market alone. Three things did the work.
The grade came before the price. I graded the income first and concluded it was mediocre as a yield and adequate as a funding mechanism. That distinction is the entire deal. Buyers who grade a property on its advertised yield either overpay for good income or walk away from good land.
The holding was funded. A value-add play with no income is a bet with a clock on it. The lease meant we could take 22 months to do the planning work without pressure to transact. That's why the income grade matters even when the income isn't the point.
The buyer was identified before the work started. We weren't building warehouses. We were building a package that a developer or an owner-occupier group could take from concept to construction without repeating our two years of planning work. The exit was designed at purchase.
That last point is the one most investors skip. Manufactured value is only real when somebody else will pay for it.
How to spot this in your own search
You don't need a $3.85 million cheque to use the logic. The pattern repeats at every size.
Look for the mismatch between what a property earns and what it holds. Low site coverage in an employment or industrial zone. Long frontage with dual access. A lease that's dull but functional. Anything where the agent's marketing is entirely about the income and entirely silent on the land.
Then do the unglamorous work: check what the zone actually permits, check precinct supply and how much competing space is already approved, and price the lease properly with a term and reversion approach rather than accepting the guide. If the numbers don't say yes, you don't buy.
This is the territory where my commercial lane and my development sites lane shake hands. Sometimes the answer is a graded income asset you hold for a decade. Sometimes it's a landholding with a rent cheque attached and a masterplan waiting. The analysis that separates them is the same analysis.
Dry Creek is Receipt 03 on the results page, sitting alongside the residential and SMSF purchases. Individual outcomes vary, and this one was my own capital at risk alongside two partners rather than a client engagement. The method is what transfers, not the result.
If you're a residential investor wondering whether commercial is even in range, the Commercial Ready Check is a free five-minute self-test on equity, lending position and risk comfort. Most people assume commercial starts at $5 million. It usually doesn't.
Bring me a listing, not a decision
The part of this I'd most like you to take away: the difference between a 4% yield you walk from and a $900,000 outcome was one question asked in the right order. What is this actually, before what does it pay.
If you have a commercial or industrial listing in front of you right now, bring it to a strategy call. You'll leave with the Deal Grade on the building and the income, the term and reversion pricing logic, the cap rate comps, and an honest read on whether the land is doing anything the listing isn't mentioning. The property analysis and cash flow model are free on your strategy call.
Frequently asked questions
What is a value-add commercial property?
A value-add commercial property is one where the current income understates what the asset could produce or be worth. The upside usually sits in one of three places: upgrading the tenant covenant, capturing reversion on an under-rented lease, or increasing lettable area through mezzanines, expansions or new buildings on surplus land. A property is only genuinely value-add if the upside is achievable under the zoning and someone will pay for it once realised.
How do you add value to commercial property without redeveloping it?
By doing the planning and positioning work that a future developer would otherwise have to do themselves, then selling that work with the site. Masterplanning, concept designs, precinct and demand analysis, and a clear project identity can all be completed before a development application is lodged. The existing lease funds the holding period while the work is done.
Why does site coverage matter when buying industrial property?
Site coverage is the proportion of a site occupied by buildings. Low coverage, broadly under 30%, means a large share of what you're buying is undeveloped land rather than income-producing floor space. In a zone that permits further development, that surplus land is often worth more than the building on it, but the advertised yield will never reflect it.
Can you sell a development project before the DA is approved?
Yes. Buyers regularly acquire sites with completed masterplanning and design work but no lodged or approved development application, because the planning work removes time and cost from their own process. The price reflects the remaining approval risk, which the buyer takes on. This is general information, not advice on any particular transaction.
Are Adelaide industrial yields still compressing in 2026?
Published research points in mixed directions. CBRE recorded Adelaide super prime midpoint yields at around 6.0% in Q1 2026 after a period of compression, while Knight Frank's Q1 2026 range for institutional grade assets was 5.75% to 6.25%. Land values have continued rising, with JLL reporting double-digit annual growth across small and medium lot sizes. Market conditions change, so treat any published figure as a snapshot rather than a forecast.
