Supply and liquidity
New housing supply, approvals, completions and how easily a market trades.
5 guides
Supply
Pipeline is not stock. What is approved is not what has arrived.
How housing supply affects property markets
Stock versus flow: existing dwellings, planning approvals, building approvals, commencements, completions. ABS for macro, local registers for the lot.
Approvals ≠ completions
A building approval is permission to start. Many never become dwellings.
Approvals vs completions: reading the supply pipeline
Planning permission is not a building approval, a start, a finish or an occupied home. No generic 1 to 3 year rule.
Apartment pipeline
New towers compete hardest with similar bedrooms in the same building class — if they complete.
How new apartment supply affects existing apartments
Ask substitute-competition questions of the pipeline. New stock is not a mechanical price law. Houses are usually a different market.
Greenfield
New lots compete with established houses that a first-home buyer can actually substitute.
How greenfield supply affects house markets
From rezoning to a titled lot to a completed house. House-and-land is not an established home. Servicing can stall a front.
Liquidity
How easily like property trades: volume and time on market — not how “hot” a suburb feels.
What is property market liquidity?
Observable proxies: turnover, consistent days on market, failed campaigns, sample depth. Not a claim that a sale was near worth.
