How the development value calculation works
Gross development value = completed units × average sale value per unit.
Example calculation
80 completed units at an average €350k selling price produce €28.0m of GDV.
INVESTMENT USE
How professionals use the result
Use GDV as the top-line value in a sell-out appraisal, then deduct selling costs, development costs, finance and target profit.
Common mistakes
- Ignoring unit mix
- Using asking prices rather than net achieved prices
