How development finance is sized
Senior development debt is capped by two tests at once: a share of gross development value (GDV) and a share of total project cost (land plus build). Lenders advance the lower of the two, so a strong GDV does not help if your costs are thin, and vice versa. The headline numbers brokers and lenders talk about are loan-to-GDV (LTGDV) and loan-to-cost (LTC).
Typical senior limits
- Loan-to-GDV: up to ~65% of GDV
- Loan-to-cost: up to ~90% of total cost
- Profit on cost: lenders like to see ~20%+
- Stretch senior / mezzanine can push these higher
This is a rough appraisal, not a credit decision — interest roll-up, fees, contingency, professional costs and your exit all move the real numbers. Tell us the scheme and we shop the whole market for the best leverage and rate for your case.
