Understanding the Numbers
Total Development Cost (TDC)
The sum of all project costs including land, construction, professional fees, contingency, and capitalised interest.
Gross Realisation Value (GRV)
The total estimated end value of all completed units or lots when sold. This is a key metric lenders use to assess project viability.
LVR on GRV
Loan-to-Value Ratio measured against the Gross Realisation Value. Most senior lenders cap this at 65–70% for development projects.
Lend-to-TDC
The percentage of Total Development Costs covered by the loan. Lenders typically fund 75–80% of TDC for well-structured projects.
Profit Margin
Most lenders require a minimum 15–20% profit margin on TDC to demonstrate the project is commercially viable and has sufficient buffer.
Peak Debt
The maximum outstanding loan balance during the project, typically occurring just before settlement of completed units begins.
