A development appraisal can look profitable on paper, then lose its margin because a cost has been missed, under-allowed or cannot be funded when it falls due. Knowing what costs are included in development finance is therefore not just a lending question. It is central to protecting cash flow, securing the right facility and delivering a scheme that meets its projected profit.
Development finance is designed to fund a project from acquisition through to completion, usually with loan advances released in stages as work progresses. Yet no two lenders fund precisely the same cost categories or to the same percentage. The strength of the borrower, planning position, build contract, loan-to-cost, gross development value and proposed exit all affect the final structure.
What costs are included in development finance?
In broad terms, a development finance facility may cover land or property acquisition, construction expenditure, professional fees, certain finance costs and a contingency allowance. Most lenders will assess these against the total development cost and the projected gross development value, often referred to as GDV.
The critical distinction is between an eligible project cost and an amount the lender will actually advance. A lender may recognise a cost in the appraisal but require you to contribute some of it from your own equity. They will also retain a margin for risk, so a facility rarely covers every pound of a scheme.
Land or site acquisition costs
For a ground-up development, the land purchase is usually the first major cost. For conversion, refurbishment or part-built schemes, it may be the purchase price of the existing property. Development lenders can fund a proportion of this acquisition, particularly where planning is in place and the projected GDV supports the loan.
However, the lender’s valuation is decisive. If you agree to pay more than the valuer considers reasonable, the shortfall will normally need to come from your own funds. This is one reason experienced developers do not rely solely on an estate agent’s opinion or optimistic comparable evidence when agreeing a purchase.
Acquisition-related expenses should also be budgeted. These can include Stamp Duty Land Tax, legal fees, valuation fees, broker fees and, where relevant, auction fees. Some can be incorporated into the facility, but others may need to be paid up front. Ask this question early, because a deal can be viable overall while still creating a sizeable cash requirement at completion.
Construction and refurbishment costs
Build costs are the core of most development finance loans. They generally include labour, materials, plant, subcontractors and the costs of delivering the agreed works specification. In a refurbishment project, this could cover structural repairs, rewiring, plumbing, kitchens, bathrooms, roofing and finishes. In a new-build scheme, it extends from groundworks and foundations through to utilities, fit-out and external works.
Rather than releasing the full construction budget on day one, lenders usually draw funds in arrears against work completed. A monitoring surveyor may inspect the site and confirm progress before each drawdown. This protects the lender, but it means the developer must plan working capital carefully. You may need enough liquidity to start a phase of works before reclaiming that expenditure through the next loan advance.
Build budgets need to be credible, itemised and supported by a schedule of works or fixed-price contract where possible. A low tender price is not automatically a benefit if the contractor lacks capacity, omits key items or is likely to seek variations later. Lenders will be focused on whether the budget can genuinely deliver the finished asset.
Professional, statutory and site costs
A viable project has costs beyond the contractor’s invoice. Development finance can often include professional fees where they are necessary to obtain consent, manage construction and complete the scheme. Depending on the project, these may include architect, planning consultant, structural engineer, quantity surveyor, project manager, building control and warranty provider fees.
Statutory and technical costs can be equally material. Planning application charges, Community Infrastructure Levy, Section 106 obligations, building regulations fees, ecology reports, drainage surveys, utility connections and highway works can all affect the development budget. On complex sites, ground investigation, contamination remediation, flood mitigation and retaining structures may be substantial.
Whether these items are fully funded depends on the lender and the evidence available. A cost supported by quotations, planning documentation and specialist reports is far easier to underwrite than a vague allowance. If a site has potential abnormal costs, disclose them early. Surprises discovered after completion can delay work and erode profit far faster than a higher initial budget.
Finance costs and interest reserves
The finance itself has a cost, and many development facilities include an interest reserve. This means interest is calculated throughout the term but retained within the loan rather than paid monthly from your bank account. It can make project cash flow more manageable, particularly while a site is generating no income.
The interest reserve is not free money. It forms part of the total debt and must be repaid from sales, refinance or another agreed exit. Arrangement fees, exit fees, monitoring surveyor fees, valuation fees and legal costs may also be included in the overall facility or deducted at drawdown. The exact treatment varies, so compare the net funds available, not simply the headline loan figure.
A lower monthly interest rate does not automatically make one offer cheaper. A facility with larger fees, restrictive drawdown conditions or an insufficient interest reserve could place more pressure on the project than a slightly higher-priced loan with a more workable structure. The right comparison is based on total cost, timing of funds and the certainty that the facility supports your delivery programme.
Contingency: the cost allowance that protects the margin
Most lenders expect a contingency allowance, often calculated as a percentage of build costs. It is there to absorb unforeseen expenditure such as price increases, additional structural works, delays caused by weather or specification changes required by building control.
The appropriate figure depends on the scheme. A straightforward light refurbishment with a detailed scope may justify a lower contingency than a conversion of an older commercial building, where hidden defects and service upgrades are more likely. Planning conditions, a constrained site or an unproven contractor should also lead to a more cautious allowance.
Do not treat contingency as spare profit. A lender may only release it when a genuine cost overrun is evidenced, and its availability may be subject to approval. If it remains unused, that is good news for your profit, but it should not be relied upon as cash for upgrades or additional acquisitions.
Costs that may sit outside the facility
Even a strong development finance package will usually require borrower equity. The lender may ask you to fund a proportion of the purchase price, costs incurred before drawdown, VAT timing gaps or any expenditure above agreed loan-to-cost limits. If the valuation comes in below expectations, the equity requirement can increase.
VAT needs particular care. Whether VAT is recoverable, chargeable or a genuine project cost depends on the property type, works and ownership structure. A specialist accountant should confirm the treatment before you finalise your appraisal. Funding a VAT payment is one issue; being unable to recover it is a very different commercial outcome.
Marketing and sales costs should also be considered. Estate agent fees, sales legal fees, show-home expenditure and incentives may be included in a development appraisal, but lenders differ on whether they advance funds for them. For rental exits, the equivalent consideration is refinance: the completed value, rental income, stress testing and mortgage availability must support repayment of the development loan.
Build the facility around the exit, not just the works
A lender will want to see a clear route to repayment, typically open-market sales or refinance onto a buy-to-let, commercial mortgage or portfolio facility. That exit determines how much debt the project can safely carry and how much contingency your profit margin can withstand.
Before committing to a site, model a slower build, a higher build cost and a lower end value. If the deal only works under perfect conditions, it is not a strong development proposition. A realistic appraisal gives you a better chance of securing competitive funding and making decisions from a position of control.
The most effective finance structure is not necessarily the one with the largest headline loan. It is the one that funds the right costs, releases money when the project needs it and leaves enough margin to reward the risk you are taking. A specialist adviser such as Max Property Finance can help test that structure before your deposit is committed.
