Before You Trust the Revenue Line: Test Buyer Concentration Risk

A feasibility can show several dwellings and still depend on one narrow revenue bet. Perhaps every townhouse targets the same buyer, the premium lots carry most of the margin, or one untested end value supports the entire land price.

A capable developer asks not only, “What is total revenue?” but also, “Where is revenue concentrated, and what happens if that segment underperforms?”

Use the MIX test

1. Map: group forecast revenue by product, buyer need, price band, stage and evidence source.
2. Isolate: identify which group contributes the largest share of revenue and profit.
3. eXperiment: apply slower sales, lower prices, incentives and changed product mix to the concentrated segment.

Government risk guidance supports rating risks, assigning controls and monitoring them. NSW pre-lodgement guidance illustrates why the proposal and site constraints should be explored early. Neither confirms buyer demand; revenue evidence must match the location, product, timing and intended exit.

A clearly labelled hypothetical

A six-townhouse project forecasts $5.4 million in gross realisation. Three larger dwellings represent 58 per cent of revenue and nearly all forecast profit because they carry a premium not demonstrated by settled comparable sales. The developer tests a 7 per cent price reduction and a longer selling period for those three, then asks the designer and agent whether a different mix could broaden demand without compromising planning or build efficiency.

Ask four concentration questions

• What percentage of gross revenue depends on the largest product group?
• What percentage of profit disappears if its premium narrows?
• Are the comparable sales genuinely similar in size, finish, date and buyer appeal?
• Can design, staging, presales or exit pathways reduce dependence without adding greater risk?

Do not create diversity for its own sake. Extra product types may increase design, approval, construction and marketing complexity. Compare the risk reduced with the cost introduced.

The Think Property Club System links market evidence to the feasibility rather than treating an agent's top-line opinion as a fixed fact. Strategy shapes product and exit; Specialists test planning, design, valuation, finance and sales assumptions within their competence.

Your next action

Colour-code each revenue line in your feasibility by product and buyer segment. Recalculate the result after stressing the largest group on price and time.

Key Takeaway

Total revenue can look diversified while project profit rests on one fragile premium; expose that concentration before it sets your offer ceiling.

Your Turn
