GDV: Gross Development Value Meaning
GDV stands for Gross Development Value. It is the estimated total value of a property development once it's completed and fully sold or let. The term is used across property, development finance, construction and real estate, and it is the single most important number in any development finance application: it's the end value a scheme is measured and lent against.
Why GDV Matters
Lenders use GDV to calculate how much they're willing to lend. The key ratio is LTGDV (Loan to Gross Development Value) (see LTC vs LTV vs GDV vs LTGDV for how the development ratios compare): most development finance lenders cap lending at 60%–65% of GDV.
If your GDV is £2,000,000, a lender offering 65% LTGDV would lend up to £1,300,000 (across land and build costs).
GDV also determines whether a project is commercially viable. If the total development cost is close to or exceeds the GDV, the project doesn't stack up, and no lender will fund it.
How to Calculate GDV
GDV is typically based on comparable evidence: what similar completed properties have sold for in the area.
For a residential development:
- 10 units × £250,000 average sale price = £2,500,000 GDV
For a commercial property:
- Annual rental income × yield multiplier = capital value
- E.g., £120,000 rent ÷ 6% yield = £2,000,000 GDV
Lenders will instruct an independent surveyor to verify your GDV figure. Their valuation, not yours, is what the lending decision is based on.
Example
A developer is converting a former office building into 6 flats:
| Component | Value |
|---|---|
| 2 × 1-bed flats @ £180,000 | £360,000 |
| 3 × 2-bed flats @ £260,000 | £780,000 |
| 1 × 3-bed flat @ £350,000 | £350,000 |
| Total GDV | £1,490,000 |
If total project costs (purchase + build + fees) are £950,000, the profit margin is roughly 36% on cost: a healthy margin that lenders would view favourably.
