A £3.7 million residential development with a £5.2 million GDV produced more than £1 million of difference between the highest and lowest modelled lender advances in new Brickflow research — illustrating why the amount of developer capital consumed by a scheme can matter considerably more than a small difference in headline interest rate.
Developers spend considerable time testing build costs, sales values, professional fees, contingencies and projected profit before committing capital to a scheme.
Yet one of the largest variables in the appraisal can emerge only when the finance itself is properly compared.
New research published by specialist property-finance platform Brickflow on 26 August analysed 300 simulated finance searches across development finance, bridging and commercial mortgages.
The objective was to compare the net proceeds generated when different lenders assessed comparable borrowing scenarios.
The results showed material variations across all three areas of specialist property finance. The largest individual development-finance gap exceeded £1.03 million on the same modelled £3.7 million project. :contentReference[oaicite:0]{index=0}
Brickflow Research: The Funding Gaps
Across the simulated searches, Brickflow reported:
- £250,000 average difference in net proceeds on a £1.4m bridging purchase;
- £306,000 average difference on a £1.5m commercial purchase;
- £842,000 average difference on development finance for a £3.7m project with a £5.2m GDV; and
- £1,030,326 difference between the highest and lowest modelled advances on one Welsh residential development.
These figures come from simulated searches produced by Brickflow rather than completed whole-market transaction data. Brickflow is itself a commercial specialist-finance comparison platform, so the findings should be understood in that context.
What Happened on the £3.7m Development?
The most striking example in Brickflow's research involved a residential development in Wales.
The modelled project had a cost of £3.7 million and a projected £5.2 million gross development value.
When the same scheme was assessed across different lending options, the most competitive modelled net advance reached £3,371,262.
At the other end of the comparison, the net advance was £2,340,936.
That produced a difference of £1,030,326 in available debt on the same underlying scheme. :contentReference[oaicite:1]{index=1}
For a developer, that is not a marginal pricing difference.
It potentially changes the amount of personal or corporate capital that has to be committed to the project by seven figures.
Development Finance Is Not Just an Interest-Rate Comparison
Development lending is fundamentally different from comparing two conventional mortgages with broadly equivalent structures.
A quoted interest rate tells a developer something about the cost of borrowing, but it does not by itself tell them how much capital the lender will actually provide.
Development facilities can be constrained through several interacting measures, including:
- loan-to-cost;
- loan-to-gross-development-value;
- minimum developer equity;
- maximum day-one land advance;
- whether interest is retained or serviced;
- whether interest is funded inside or outside the stated facility;
- how professional and finance costs are treated;
- drawdown mechanics;
- contingency requirements; and
- the lender's valuation of the completed development.
Brickflow itself notes that development finance is calculated using combinations of LTGDV, LTC, minimum client equity and day-one land-loan caps, with factors such as geography, asset type, developer experience and lender exposure also capable of influencing leverage and pricing. :contentReference[oaicite:2]{index=2}
Consequently, a lender quoting a slightly lower interest rate can still leave the developer needing considerably more cash.
Equity Is Often the Developer's Scarce Resource
This is where the research becomes commercially significant.
Debt has a cost. But for an active developer, equity also has an opportunity cost.
Suppose a sponsor has £1.5 million of capital available for new projects.
If a lender structure requires almost all of that capital to be committed to one development, the sponsor may have little capacity left to acquire another site, fund planning expenditure or provide equity for another project.
If another suitable lender can fund the same viable development while requiring materially less sponsor capital, the developer may preserve enough liquidity to maintain a wider pipeline.
That means the relevant comparison is not simply:
“Which lender has the lowest rate?”
It is:
“Which suitable capital structure gives this project the funding it needs while using the developer's equity most efficiently?”
A Small Rate Saving Can Be Less Valuable Than a Large Equity Saving
Developers understandably focus on the cost of finance because interest and fees directly reduce scheme profit.
But rate should be considered alongside leverage.
A difference of 20 or 30 basis points can matter on a multimillion-pound facility. Yet it may be economically secondary if obtaining that lower rate requires the sponsor to commit several hundred thousand pounds of additional equity.
That additional cash cannot simultaneously be used for another acquisition, planning application, option payment or project.
For an active development business, the effect can therefore extend beyond the return generated by one scheme.
It can affect how many projects the developer is capable of undertaking with the same equity base.
Compare the Capital Structure, Not Just the Rate
A meaningful development-finance comparison should normally put the following figures side by side:
- day-one net advance;
- total facility;
- loan-to-cost;
- loan-to-GDV;
- developer equity required;
- interest rate and calculation basis;
- retained versus serviced interest;
- arrangement and exit fees;
- valuation, monitoring and legal costs;
- drawdown timing;
- minimum equity requirements;
- personal guarantees and other security;
- sales conditions or pre-sale requirements; and
- the proposed repayment exit.
Only then can the developer see the economic impact of each option on both the project and the wider development business.
The Same Principle Applies to Bridging Finance
Brickflow's analysis found an average £250,000 difference in net lending on its modelled £1.4 million bridging transactions.
One London residential purchase produced a particularly wide range.
The highest modelled net loan was £979,265, while the lowest was £646,106 — a difference of £333,159. Brickflow calculated that the higher advance represented 52% more debt against the same asset. :contentReference[oaicite:3]{index=3}
Again, headline LTV does not always tell the complete story.
A bridging facility can be affected by whether the lender quotes gross or net LTV, retained interest, arrangement fees, minimum interest periods, valuation methodology and whether fees are added to or deducted from the advance.
A borrower who believes they are comparing two similar 70% or 75% LTV facilities can therefore discover that the actual cash available on completion is materially different.
Commercial Mortgages Produced Similar Variations
The same pattern appeared in commercial finance.
Brickflow reported an average difference of £306,000 on modelled £1.5 million commercial purchases.
In one North West retail-property example, net advances ranged from £1.125 million to £750,000 — a £375,000 difference on the same purchase scenario. :contentReference[oaicite:4]{index=4}
Commercial mortgage leverage can depend on far more than the property's purchase price.
Rental income, tenant quality, lease length, vacant possession value, investment value, property type, borrower experience and the lender's appetite for a particular sector can all influence the amount available.
A borrower therefore needs to understand both the lender's pricing and the underwriting methodology that sits behind the proposed leverage.
Why Lenders Can Reach Different Answers on the Same Development
The difference does not necessarily mean one lender has calculated the deal correctly and another incorrectly.
Specialist property lenders have different risk appetites and funding models.
One lender may be comfortable at a higher LTGDV but apply a tighter LTC restriction.
Another may lend more heavily against land at day one but require more conservative staged drawdowns.
A lender may have strong appetite for experienced regional housebuilders but be more cautious about a first-time developer.
Another may have reached its internal exposure limit for a particular geography or property type.
Lenders can also take different views of the same valuation, construction method, planning position, sales strategy or exit.
This is precisely why development finance is a structuring exercise rather than simply a product-selection exercise.
The £1m Difference Needs an Important Caveat
Brickflow's figures are useful, but they should not be interpreted as evidence that every developer is currently losing £1 million by choosing the wrong lender.
The research is based on 300 simulated specialist-finance searches, not 300 completed transactions recorded independently across the whole UK lending market.
Brickflow also has a direct commercial interest in encouraging developers and brokers to compare a broad range of lenders through its platform.
Its own borrower information explains that it uses a consistent modelling process to compare lenders and that figures generated on its results screens can differ from final lender quotations, although Brickflow says it monitors those estimates against actual quotes. :contentReference[oaicite:5]{index=5}
Those limitations matter.
However, they do not undermine the broader financing principle illustrated by the exercise.
Development lenders genuinely do apply different LTC, LTGDV, day-one and equity parameters, and those differences can materially change the amount of sponsor capital required.
More Debt Is Not Automatically Better
There is an equally important qualification for developers.
The lender offering the largest facility is not automatically the right lender.
Higher leverage normally increases financial risk.
A developer should consider whether the scheme can withstand construction delays, cost overruns, slower sales, reduced GDV or a longer interest period.
The facility also needs to be deliverable.
An apparently attractive high-leverage offer may be of little value if its conditions are unrealistic, its valuation assumptions cannot be achieved or its credit process does not fit the transaction timetable.
Likewise, personal guarantees, cost-overrun guarantees, pre-sale conditions and other covenants may make a lower-leverage lender more appropriate for a particular sponsor.
The objective is therefore not to maximise debt at any cost.
It is to find the appropriate balance between leverage, cost, risk, certainty and capital efficiency.
Developers With Several Projects Have More to Gain From Capital Efficiency
This issue becomes particularly important for developers operating a pipeline rather than a single scheme.
Imagine a developer considering three potential projects.
All three may be viable on paper. But each requires an equity contribution before development debt can be deployed.
If the financing structure on the first project absorbs substantially more equity than necessary, the second and third projects may have to be delayed even though the business has adequate experience and each scheme is individually profitable.
For a growing developer, the constraint can therefore be deployable equity rather than access to debt itself.
This changes the purpose of the finance search.
The broker is not simply trying to get Project A funded.
The financing needs to be considered in the context of Projects B and C as well.
Existing Property Can Sometimes Change the Structure
Developers and investors may also have equity sitting elsewhere in their balance sheet.
That might include completed investment properties, unencumbered land, a trading commercial asset or another development approaching exit.
Depending on the circumstances, additional security can sometimes alter the way a new transaction is structured.
A lender may consider cross-collateral security, a separate bridge against another asset or another form of secured funding.
That does not automatically make the transaction better. Cross-collateralising assets can increase the amount of property exposed if a project fails.
But it illustrates why development finance should be considered against the sponsor's wider property position rather than assuming the new site must always be financed entirely in isolation.
Introducers Should Look for Clients With Too Much Cash Trapped in Projects
The research also creates a useful conversation for accountants, quantity surveyors, development managers, lawyers and other professional advisers.
An accountant may be able to see that a successful development business has substantial capital tied up across several schemes.
A QS may identify that the development facility is not keeping pace with construction expenditure, forcing the sponsor to inject cash earlier than expected.
A lawyer or land agent may know that the developer is struggling to complete another acquisition because too much capital is committed elsewhere.
Those situations do not necessarily mean the underlying development is performing badly.
The issue may instead be that the finance structure is consuming more of the sponsor's capital than another viable lender structure would require.
A Development Capital Efficiency Review
For developers with schemes in the £2 million to £20 million range, a useful funding review should go beyond asking which lenders are willing to finance the project.
The first stage is to establish the complete development appraisal: land cost, acquisition costs, construction costs, professional fees, finance, contingency, projected GDV, sales timetable and required developer return.
The next stage is to compare how suitable lenders translate that appraisal into an actual facility.
| Comparison | Lender A | Lender B | Why It Matters |
|---|---|---|---|
| Day-one advance | Compare | Compare | Determines cash required to acquire or refinance the site |
| Total facility | Compare | Compare | Shows total debt potentially available through the project |
| LTC / LTGDV | Compare | Compare | Can materially change maximum leverage |
| Developer equity | Compare | Compare | Shows how much sponsor capital is tied up |
| Interest treatment | Compare | Compare | Affects both facility size and cash flow |
| Drawdowns | Compare | Compare | Determines when debt becomes available against expenditure |
| Guarantees / security | Compare | Compare | Changes the sponsor's wider risk exposure |
| Exit conditions | Compare | Compare | Can affect sales, refinance and repayment flexibility |
That comparison can reveal something a simple rate table cannot: how much of the developer's own capital each structure consumes and what that means for the wider pipeline.
The Finance Decision Can Determine How Quickly a Developer Scales
Brickflow's latest research provides a useful illustration of a principle experienced developers already encounter in practice.
The difference between lenders is not limited to interest rates.
On the same development, different approaches to leverage can potentially alter the available debt by hundreds of thousands of pounds — and, in Brickflow's most extreme modelled example, by more than £1 million.
For an active developer, that difference can influence far more than the profitability of one project.
It can determine how much equity remains available for the next site.
That is why development finance should be judged not merely on the price of the debt, but on how effectively the facility allows the developer to deploy their own capital.
Is Your Development Facility Using More Equity Than It Needs To?
A development loan can look competitive on rate while still requiring substantially more sponsor capital than another suitable structure.
Willow Private Finance can compare development lenders across day-one leverage, total facility, LTC, LTGDV, interest treatment, drawdowns, fees, guarantees and the developer equity required — allowing the funding decision to be considered against both the current scheme and the wider development pipeline.
For developers running several projects, the objective is not simply to obtain the largest loan. It is to structure appropriate debt while preserving capital for the opportunities that follow.
Explore Development Finance →Frequently Asked Questions
Development finance can vary materially between lenders because leverage, equity, interest treatment and drawdown structures are not standardised across the market.
Why can two development finance lenders offer very different loan amounts on the same project?
Development lenders can apply different limits to loan-to-cost, loan-to-GDV, minimum developer equity, day-one land advances, interest treatment and other elements of the facility. Their appetite can also vary by location, asset type, developer experience and current loan-book exposure. As a result, two lenders can produce materially different net advances even when assessing the same scheme.
What did the Brickflow research find on development finance?
Brickflow analysed simulated specialist-finance searches and reported an average £842,000 difference between the highest and lowest net development finance proceeds on a modelled £3.7 million project with a £5.2 million GDV. In one Welsh residential development scenario, the difference exceeded £1.03 million.
Is the development finance lender with the lowest interest rate always the cheapest option?
Not necessarily. Developers should consider the entire facility, including the net advance, retained or serviced interest, fees, drawdown mechanics, loan-to-cost, loan-to-GDV, equity contribution, guarantees and exit conditions. A lower headline rate can be less attractive if the structure requires substantially more developer equity.
How much equity does a developer normally need?
There is no universal equity requirement. It depends on the land value, total development cost, GDV, lender criteria, developer experience and structure of the transaction. Different lenders can calculate the required developer contribution very differently, which is why the available market should be assessed against the specific project.
What should developers compare when choosing development finance?
Developers should compare the net day-one advance, total facility, loan-to-cost, loan-to-GDV, equity required, interest treatment, arrangement and professional fees, drawdown timing, guarantees, covenants and exit requirements. The objective is to understand the complete capital structure rather than comparing the headline interest rate alone.
