What is the Difference Between GDV and Purchase Price for Development Lending?
When diving into the world of development finance, understanding the differences between the Gross Development Value (GDV) and the purchase price is crucial. These terms significantly impact lender underwriting decisions, affect loan-to-value calculations, and ultimately influence the feasibility of your project financing. Whether you’re a seasoned developer or exploring your first project, this guide will walk you through the essentials, explain development finance mechanics, and highlight why broker choice matters.
Understanding GDV and Purchase Price
What is GDV (Gross Development Value)?
The Gross Development Value is an estimate of the total market value of a completed development project once fully built, sold or leased. It represents the future value, assuming the property or properties achieve their anticipated sales prices or rental values in the current market.
In simple terms, if you’re developing a block of flats, the GDV is the projected combined sales value of all the flats when the building is finished.
What is Purchase Price?
The purchase price is the actual amount you pay to acquire the land or property before development begins. This is typically the initial capital outlay required to secure the site.
Purchase price is a historical or current cost, while GDV is a forward-looking estimate. This distinction is important for lenders when structuring development finance.
Why GDV vs Purchase Price Matters in Development Lending
Lenders in development finance don’t just look at how much you pay for a site but pay significant attention to the GDV — because the GDV underpins the exit value that will pay off the loan.
Let’s look at the main reasons the difference matters:
- Loan-to-Value (LTV) Ratios: Most development loans are offered as a percentage of GDV (e.g. up to 70% GDV). Since GDV is almost always higher than purchase price, basing LTV on GDV allows for larger loan amounts relative to purchase price.
- Risk Assessment: Lenders assess whether the projected GDV justifies the risks involved. Overestimating GDV can be fatal; lenders carefully underwrite GDV.
- Loan-to-Cost (LTC) Considerations: Loan-to-cost refers to the loan relative to total project cost (including purchase price and construction costs). Both LTC and GDV ratios help lenders understand risk balance.
- Staged Drawdowns: Understanding GDV guides lenders on release schedules tied to construction milestones and valuation uplifts.
Development Finance Mechanics: How Drawdowns Relate to GDV and Progress
Unlike typical mortgages, development finance loans are usually not released in one lump sum. Instead, lenders release funds in stages or “drawdowns,” structured around project progress and valuation updates.

- Initial Advance: Often covers a percentage of the purchase price to help you buy the land or existing property.
- Construction Drawdowns: Subsequent releases are tied to completion of certain development milestones, typically verified by onsite inspections or valuations.
- Retention and Final Payment: A final tranche is sometimes withheld until the entire project is complete and fully valued at or near the appraised GDV.
This staged approach mitigates risk for lenders and aligns financing with build progress.
Key Ratios Explained Simply: LTV and Loan-to-Cost
Term Definition Calculation Typical Range in Development Lending Loan-to-Value (LTV) Loan amount as a percentage of GDV (Loan Amount ÷ GDV) × 100% Up to 60%-70% GDV Loan-to-Cost (LTC) Loan amount as a percentage of total project cost (Purchase Price + Build Costs) (Loan Amount ÷ Total Project Cost) × 100% Typically 70%-85% LTCUnderstanding these ratios enables developers to plan suitable financing strategies and manage affordability.
Broker Selection Criteria: Speed, Transparency & Lender Access
Choosing the right broker can make or break your development lending experience. Here are the crucial aspects to consider:
Speed and Efficiency
Development projects operate on tight timelines. Brokers known for rapid turnaround times can improve chances of timely financing.
Access to Multi-Lender Panels

Transparency in Fees and Process
Beware of brokers who hide fees or don’t disclose all terms upfront. Transparent brokers will detail costs, loan bands, and lending parameters early, avoiding surprises.

Deal Size Capacity and Published Loan Bands
Understanding the typical loan size each broker or lender handles is another vital factor. For example:

- The Loans Engine covers a similar range but can occasionally handle larger projects depending on lender appetite.

Knowing these bands prevents applying to brokers who cannot handle your deal size, saving valuable time.
Summary
To wrap up, here are the key points:
- GDV vs Purchase Price: GDV is the future market value of your completed project, while purchase price is your initial cost. Lenders prioritise GDV for underwriting.
- LTV and LTC Ratios: These ratios balance loan amount against project value and cost, guiding lender risk appetite.
- Development Finance Drawdowns: Funds are typically released in stages aligned with build progress and valuation uplifts.
- Broker Selection: Choose brokers who offer transparency, quick decision-making, and access to multi-lender panels such as KIS Finance and The Loans Engine for UK-wide deals or Scottish Bridging Loans for Scottish projects.
- Deal Size Awareness: Ensure your project fits within the broker’s published loan bands to ensure suitability.
