The role of valuations in development finance
The RICS (Royal Institution of Chartered Surveyors) valuation is one of the most critical components of the development finance process. It provides the lender with an independent assessment of the property's current market value, the gross development value (GDV) of the completed scheme, and the viability of the development proposal. Lending decisions, facility sizes, and loan covenants are all based on the valuation figures.
All development finance valuations are prepared in accordance with RICS Valuation — Global Standards (the "Red Book"), which sets out the professional standards, bases of value, and reporting requirements that valuers must follow. Red Book compliance ensures consistency, transparency, and professional accountability in the valuation process.
The valuer is instructed by the lender (not the borrower), and their primary duty is to the lender. However, the borrower pays for the valuation and has a right to see the report (which is shared by the lender during the due diligence process). This creates a dynamic where the borrower has a financial interest in the outcome but no control over it.
Valuation methods for development sites
The residual method is the primary valuation approach for development sites. The valuer estimates the GDV of the completed development, deducts all development costs (construction, professional fees, finance costs, marketing costs, developer's profit), and the residual figure represents the site's current market value.
The formula is: Site value = GDV - (Construction costs + Professional fees + Finance costs + Marketing costs + Developer's profit + Contingency). Each element requires the valuer to make informed judgments based on market evidence, experience, and professional standards.
The comparable method is used to assess GDV by reference to prices achieved for similar properties in the local market. The valuer identifies comparable transactions — recent sales of similar properties in similar locations — and adjusts for differences in size, specification, condition, and location. The quality and relevance of comparable evidence directly affects the confidence of the GDV assessment.
The investment method is used for schemes where the exit is investment sale rather than individual unit sales (e.g., build to rent, student accommodation, care homes). The valuer capitalises the projected net income at an appropriate yield to arrive at the investment value, which functions as the GDV for development finance purposes.
What the valuer assesses
Current site value. The value of the site in its current condition, with or without planning permission. This establishes the baseline for the lender's day-one security and informs the initial drawdown (typically 60-70% of current site value for the land acquisition tranche).
Gross development value. The aggregate value of the completed development — typically the sum of individual unit values for a residential scheme. The valuer assesses each unit type based on comparable evidence, adjusting for floor level, aspect, specification, and other relevant factors. This is the figure against which the LTGDV ratio is calculated.
Build cost reasonableness. While the valuer is not a quantity surveyor, they will comment on whether the proposed build costs appear reasonable in the context of the development. If the costs appear materially low or high, the valuer may flag this to the lender as a concern.
Market conditions and risk factors. The valuation report includes commentary on local market conditions, supply and demand dynamics, and any risk factors that may affect the development's viability or the achievability of the GDV. This qualitative assessment informs the lender's overall risk evaluation.
Common valuation issues in development finance
GDV shortfall. The most common issue is when the valuer's GDV assessment is lower than the developer's expectation. This can occur because the valuer uses different comparable evidence, applies different adjustments, or takes a more conservative view of market conditions. A GDV shortfall reduces the maximum facility size and may require the borrower to inject additional equity.
Insufficient comparables. In areas with limited transaction data or for unusual property types, the valuer may struggle to find relevant comparables. This creates uncertainty in the GDV assessment and may result in a more conservative valuation. Developers can help by providing their own comparable research to supplement the valuer's analysis.
Site value disagreement. The valuer's assessment of current site value may differ from the purchase price paid by the developer. If the valuation is below the purchase price, the lender will base their lending on the lower valuation figure, effectively increasing the borrower's equity requirement.
Caveats and special assumptions. Valuers may include caveats that limit the reliance the lender can place on the valuation — for example, subject to satisfactory environmental reports, subject to planning confirmation, or subject to structural survey. These caveats may create additional conditions precedent in the facility agreement that must be satisfied before drawdown.
Managing the valuation process
Developers can influence the valuation outcome positively (without improperly directing the valuer) by providing comprehensive information. A well-prepared information pack should include the planning consent and approved drawings, a detailed cost plan, marketing agent reports supporting the GDV, comparable evidence the developer has gathered, and a clear description of the development proposal.
Arranging a site visit with the valuer and being available to answer questions can also help. The valuer may have specific questions about the site, the local market, or the development proposal that can be addressed efficiently during the inspection. A knowledgeable and professional developer makes a positive impression.
If the valuation comes back lower than expected, resist the temptation to argue aggressively. Instead, review the comparable evidence used by the valuer, identify any factual errors, and provide additional evidence that may support a higher figure. The valuer may agree to review their assessment in light of new information, but they will not change their professional opinion under pressure.
Selecting the right valuer
Most lenders have panels of approved valuers and will select from this panel when instructing a valuation. Borrowers can sometimes request a specific panel valuer, and it is worth doing so if you know a valuer with strong local knowledge and development valuation experience.
The ideal valuer for a development finance instruction has specific experience in the local market, understands the development process, and has valued similar schemes previously. A valuer unfamiliar with the area or the property type is more likely to take a conservative approach, potentially resulting in a lower GDV and a smaller facility.
Some lenders will accept dual-instructed valuations (where both lender and borrower instruct the same valuer), which can save costs if the borrower also needs a valuation for their own purposes. However, the valuer's primary duty remains to the lender, and the dual instruction does not change this.
