If you’re developing property, you’ll quickly come across the term GDV (Gross Development Value). It may sound technical, but the idea is simple and extremely important to securing funding for your project.

What is Gross Development Value (GDV)?

Gross Development Value is the estimated total value of a property development once it’s completed and sold (or refinanced). In other words, it answers the question:

“What will this development be worth at the end?”

Lenders, investors, and developers all use GDV as a common reference point because it gives a forward‑looking view of the project’s potential.

What is GDV‑Based Lending?

GDV‑based lending is when a lender bases the amount they’re willing to lend on the future value of the finished development (the GDV), rather than just the current value of the site or building.

For example, a lender might agree to fund 60-70% of the GDV. If the projected GDV is £1,000,000, they might lend between £600,000 and £700,000, subject to their criteria, including a valuation.

Why GDV Matters

GDV matters because it:

• Shapes how much you can borrow: Higher GDV (backed by a comprehensive valuation) can support a larger loan.
• Helps test project viability: Comparing total costs to GDV shows whether there’s enough margin to justify the risk.
• Aligns everyone’s expectations: Developers, lenders, and investors all use GDV to assess potential returns.

If your GDV is too optimistic, you risk over‑borrowing and squeezing your profit. If it’s too conservative, you might struggle to secure enough funding.

When GDV‑Based Lending is Useful

GDV‑based lending is especially useful when:

• You’re adding significant value through construction, refurbishment, or change of use.
• The current value of the site is low, but the completed scheme will be worth much more.
• You need a flexible funding structure that reflects the project’s end value, not just today’s bricks and mortar.

For value‑add and development projects, this approach can unlock funding that wouldn’t be available if lenders considered only the current value.
